List of Pus, Acid, and Mucus Forming Foods

What foods are pus, mucus, and acid-forming? In the Mucusless Diet Healing System, Prof. Arnold Ehret asserts that pus and mucus-forming foods are the foundation of human illness and should not be eaten. In short, pus and mucus-forming foods include meat, poultry, dairy, grains, starches, and fats. Yet, it must be understood that just knowing what these foods are is not enough. It is important to know how to rationally and safety TRANSITION off of the most dangerous pus and mucus-formers over a longer period of time.

The word “mucus” is from the Latin mucus which means “slime, mold, snot, etc.” Mucus refers to a thick, viscous, slippery discharge that is comprised of dead cells, mucin, inorganic salts, water, and exfoliated cells. It also refers to the slimy, sticky, viscous substance left behind by mucus-forming foods in the body after ingestion. The word “pus” is from late 14c. Latin “pus” (related to puter [putrid] “rotten”), from Proto-Indo-European*pu- compared to Sanskrit. puyati “rots, stinks,” putih “stinking, foul.” Pus often refers to a thick white, yellowish, or greenish opaque liquid produced in infected tissue, consisting of dead white blood cells, bacteria, tissue debris, and serum. It also refers to the substance that dead animal flesh is chemically changed to after being consumed or while rotting in one’s digestive tract. The ingestion of meat and dairy products create pus residue in the body, while starchy and fatty foods are mucus-forming.

The word “mucusless,” or mucus-free, refers to foods that are not mucus-forming. Such foods digest without leaving behind a thick, viscous, slimy substance called mucus. These foods include all kinds of fat-free, and starchless, fruits and vegetables.

All foods that are pus/mucus-forming are acid-forming. The word “acid” is from the early 1600s meaning “of the taste of vinegar,” from French acide (16c.) or directly from Latin acidus “sour, sharp,” adjective of state from acere “to be sour,” from PIE root *ak- “sharp, pointed.” In chemistry it refers to a class of substances whose aqueous solutions are characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals to form salts. From a mucusless perspective, pus and mucus-forming foods are understood to be “acid-forming” inside the human body. Such foods create an acidic internal environment that is detrimental to wellness.
mucusless-diet-healing-system-kindleThree years ago we released the first revised and annotated edition of Arnold Ehret’s Mucusless Diet Healing System. The following is a list of pus, mucus, and acid-forming foods that will be in this new reference edition of the Mucusless Diet. This is not an exhaustive list, but the most common acid-forming foods. It must be emphasized that not all of these foods are forbidden on the Mucusless Diet as a Healing System. Ehret’s TRANSITION DIET will show you how to use less harmful mucus-forming foods to get off of the worst ones. Pus and Very Mucus-forming foods should be avoided from the beginning if possible. But Moderately or Slightly mucus-forming items may be used effectively during the transition. See the TRANSITION DIET section of the Mucusless Diet or Spira Speaks for more details:

What are Deceptive Mucus-Formers?

Here is a list of foods that many people do not realize create mucus:

  • Rice (great for creating glue to bind books, bad for the transition to a mucus-free diet)
  • Avocados (fatty item that may be used on the transition, but are highly addictive. Although technically a fruit, if used it is best to combine them with a mucus-free combination salad or vegetables to aid elimination. However, it is recommended to stay away from them if you are not already stuck to them.)
  • Nuts (Mucus-forming, but may be used on the transition. It is best to eat with dried fruits like raisins to aid with elimination.)
  • Plantains (Starchy)
  • Tofu (Slimy and mucus-forming.)
  • Un-ripened fruits like green bananas (the riper the fruit you eat the better).
  • Corn (It does not eliminate well. When cooked, corn becomes mushy and slimy in the intestines.)
  • Corn chips (Some people use them on the transition, but they are very addictive and do not eliminate well)
  • Beans (They are starchy and mucus-forming. But, they may be used sparingly on the transition within close proximity to green-leafy salads)
  • Starchy Vegetables (Some vegetalbes are starchy and mucus-forming in raw or cooked forms, such as white potatoes. But, many other vegetables, such as sweet potatoes, become almost mucus-free (starchless) after proper cooking.

The Transition Diet

It is very important that people learn how to transition from the most harmful mucus-forming foods to the ones that leave behind the least amount of waste. To learn more about this transitional process, check out the TRANSITION DIET section of the Mucusless Diet Healing System.

Prof. Spira is an expert on the Mucusless Diet, webmaster of, and author of “Spira Speaks: Dialogs and Essays on the Mucusless Diet Healing System” where he reveals how he lost 110lbs and overcame numerous illnesses by practicing Arnold Ehret’s Mucusless Diet Healing System. He is also the editor of the first critical edition of the diet entitled “Prof. Arnold Ehret’s Mucusless Diet Healing System: Annotated, Revised, and Editied by Prof. Spira.”

About Spira

Prof. Spira learned of Arnold Ehret's Mucusless Diet Healing System from Brother Air in 2002 and the information profoundly changed his life. By 2003 he'd lost over 110 pounds and cured many ailments including chronic migraine headaches, lower back pain, allergies, and chronic cases of bronchitis. In 2004 he and Brother Air formed the Breathairean Ensemble which would act as a support system for its members as they pursue superior health. Prof. Spira believes that Ehret uncovered the cure for chronic human illness which consists of eliminating pus and mucus forming foods from one's diet followed by a transition to mucus-free fruits, green-leaf vegetables, and fasting.

  1. any food becomes acid if is not proper digested. The best raw fruit and vegetable if not proper digested, it will become acid and even mucus forming if eating in excess.

  2. Anthony bahlibi says:

    Great article and list. Very informative and will prove helpful for its broadness and easy access.

  3. Baja says:

    There is a conflict between your list and Dr Sebi’s list. Which one is the most accurate?

    • Spira says:

      What are the items that conflict?

      • Baja says:

        Rye bread,Quinoa, Spelt, Amaranth.
        Nuts: Almonds
        Seed: Sesame seeds
        Apple Cider Vinegar
        Vanilla Extract
        Mushrooms(according to Dr Sebi is not fungus)

        • Spira says:

          I did notice this conflict years ago when I first checked out some of Dr. Sebi’s works. We both have been influenced by Prof. Ehret to varying degrees, but do not see eye to eye on all issues. Ehret explains that all fats are mucus-forming, thus all nuts, seeds, and fatty fruits (olives, avocados). Cereals are certainly mucus forming. You can test this yourself. Take a cereal product, add a bit of water and heat it at 98 degrees on the stove. Do the same to grapes. Let them both sit in an air tight bag for a few days. You will see that the cereal starts to turn into a viscous sludge, whereas the grapes turn into a kind of syrup that has no viscous, mucus-forming constituents. Like I’ve mentioned before, some of the items listed above may be used in moderation on the transition. But it must be understood that they are mucus/acid-forming and will cause illness if eaten too much. And for those aspiring to be mucusless, they will need to eventually be eliminated all together. Peace, Love, and Breath.

          • Adriano says:

            Dr Sebi is against starch, yet he recommends black & wild rice, spelt and rye. Anyone can or heard him explain this? Is it just because they are not too acid and not hybrid?

          • Spira says:

            I appreciate Dr. Sebi and love that he promotes Ehret’s works to his followers. Yet, I disagree with him on some of the foods that he lists as mucus-free vs. mucus-forming (as you pointed out a couple). I’m not quite sure why he identifies certain items that Ehret or I list as mucus-forming to be non-mucus-forming. And on the other side, we tend to not be as concerned with the hybrid vs. non-hybrid analysis. We examine how effective a food item is at eliminating from the body and leaving behind the least amount of metabolic waste or degrade into slime. Non-hybrid, Mucus-free fruits may be the highest level, but I’d rather see someone eat a hybrid mucus-free fruit than any kind of rice or grain (although some grains may be used within the context of “the transition diet,” but they should viewed as “mucuslean’ and not mucus-free).

            Peace, Love, and Breath!

          • Vito says:

            it is mainly because of hybrid and unnatural protiens and vitamins they contain that keep them from Dr Sebi’s list. that and they are to be maintained with natural herbs that naturally flush and keep body clean. The fact that they have a cell food that hybrids do not will replenish you

  4. After reading the list I got stronger and was more inclined to buy more fruits and veggies instead of what I thought I had to buy for my kids to make other people happy. But then now with more fruits and veggies they actually like it better and are eating great, even my fussy one is loving the fruits and the fried up veggies I make with onions, green bell peppers, garlic and purple cabbage. (I just add some water to cook/fry it a little with just a tiny bit of olive oil, my bad, and a tynny bit of pink salt. I was also able to cut down substancially on our sugar and salt intake. Then, happy me, after having 5 kids I am weighing my most ideal weight 128, feeling great, lots of energy, doing a lot of things I like and feeling happy again and ready to live the life I was meant to live…feel closer to God and to that higher dimension paradisial state , my ability to smell is what I normally notice first thing as a progression on my health…Thanks again this list made a huge difference for me to stop being on denial about what’s really the right things to eat which like most people say little option but who needs more when you get the best of foods???NO thanks I am done with spitting mucus…

  5. According to Prof. Ehret’s book that list from one of his partners or Dr. from his time who wrote similar list olives were on the top rant of one of the best things to eat and I was eating a lot of them, so they are not as good as it was mentioned???If not what do they resemble in the mucus level? Avocado? I really thought it was super good and ate a tons of it before.

    • Eric Sprik says:

      I noticed that too Georgia, ate quit a few myself because it also gives the next food a nice ride through the body 😉
      I also wonder if heating products to 98°C does represent the body’s processing of food. Once, I left some (cut) leek leaf lying on the bench and after half a day it would not come off. Had to hammer it off! The fluid inside had turned into a glue. Later, as an experiment I actually glued things together with leek leaves… Don’t want that (or any onion family) in my body I guess.

    • Spira says:

      The ‘list’ that Ehret has in the book is problematic. Ehret advises that you ‘take it with a grain of salt’, as it was not meant to be a recommended foods list. I will be releasing a post about the Ragnar Berg Table and its problems very soon. And olives are fatty and acidic. Although not the worst thing you could eat during the transition, I do not recommend getting too comfortable with them for extended periods of time. Peace, Love, and Breath!

      • Eric Sprik says:

        Thx Spira for keeping in touch with your readers, not so common these days. I am interested in the pursuit of truth regardless of the subject and you are helping (me and others). Love that, the world needs us.
        When my mother was pregnat of my (my body) she wanted to eat lots of pickles (the green veggie). I do not believe these are acid forming in the blood, because normally seets are acid-forming and acids re alkaline/sweet forming in the blood. Moreover, a very healthy homeless guy I know eats a lot of them and when I ate macrobiotic it was a *recommended) part of my menu; Also leaven bread with (cooked/raw) veggies was. I went out in wintertime without any coat in that period, lots of energy…
        We must search for our personal salvation and stay open for general info i.m.o. :-)

        • Eric Sprik says:


        • Spira says:

          As far as I can tell, and according to Ehret, they are acid-forming. As a rule of them, any fermented food or item with vinegar in it is acid-forming. Ehret is adamant about getting rid of vinegar as soon as possible, and I agree. Of course, if your bowels are fairly clean, such items will not be as devastating as eating pus (meat) since they will eliminate fast. Another thing is that most people who have cleansed for a while find the smell and taste of fermented foods to be awful. I used to like things that had vinegar in them, but can not stand them now that I’ve changed the nature of my taste buds.

          • Colleen K. Peltomaa says:

            Aside from the commercial krauts that sit in distilled vinegar, does this also include the home-made krauts which ferment in a brine?

            After a long fast I just asked myself, “what’s next”, and my heart says this is next, thank you for putting this information out there.

          • Spira says:

            All fermented foods are certainly acid-forming and not recommended to use at higher stages of the Mucusless Diet. Although, such items could be used during the transition. But, I normally advise people to get away from fermented foods as early in the transition as possible. Peace, Love, and Breath!

  7. Drisana Malaambo says:

    Honestly, the lifestyle seems extreme. I think about all the other parts of the world where people live in various climates without the ability to always eat fresh fruits and veges. The reason for why we created all these other foods to help sustain us such as kombucha, rich, milk, etc.. Would it be fair that all our creations in an attempt to live better were all mucus forming and essentially killing us slowly? Many cultures have lived very well in a state of health without having to be strict on all fruits and veges lifestyle. I’m not sure that it’s about perfection, but balance. Chinese medicine dates back thousands of years as does Ayurvedic medicine. Perhaps all things can be taken into consideration before making one way THE right way.

    • Spira says:

      Greetings Drisana! First, you must understand that this is not a list of ‘what foods I recommend’ on the mucusless diet, but an objective list of mucus/acid forming vs. non-acid forming foods. In the future I plan to release a list of mucusless and transitional mucus-formers that will not be as objective, but more of a ‘recommended foods’ list. We certainly respect perspectives the world over, although we may have a unique understanding or critique of them and how they work based upon our own empirical knowledge with the Mucusless Diet. Some people use the diet for short term healing, and others as a lifestyle. The methods could also be used for people who just want to transition to an improved vegan or raw-food diet. As a lifestyle, it is not as strict as many people assume, but a TRANSITIONAL DIET that includes raw and cooked mucus-free and mucus-forming foods. The key is to systematically transition away from the worst mucus-formers first to less harmful ones. I highly recommend that you take a look at the diet book to get a better understanding of what the Mucusless Diet is about. Peace, Love, and Breath!

  8. ousa says:

    I mean seriously, what is left for us to eat, your lists include each and every food that I personally know, so what are the ‘good’ food please

    • Spira says:

      These two lists were meant to be more objective, i.e. acid-binding vs. acid-forming. The lists can certainly be used to explore some options. I plan to release a list of mucusless and transitional mucus-formers that will act more as a ‘recommended foods’ list in the near future.

    Hi there :)
    Love your stuff.
    I’m sorry, I have a few questions :)
    1) What about persimmon?

    You said 98 degree :)
    2) How much time should I heat it up? like an hour or ? :)

    Thank you for all your awesome stuff.
    Best regards,
    Artem :)

    • Spira says:

      Thank you for your kind words. Persimmons are fine for the transition as long as they are good and ripe. Are you asking about cooking the persimmons or cooking in general?

      • Artem says:

        Thank you for your response :)

        I’m sorry, I wasn’t clear :)

        And, my question is -> How much time should I heat it up? Anything, I wanna test a bunch of stuff :) not only persimmons :)

        One more :) Can I just put stuff in hydrochloric acid? I heard that hydrochloric acid almost represent stomach environment.

        & :) How old is Brother Air? :) He is awesome :)

        Again, thank you very much ^^
        Best regards,

        • Spira says:

          I’ve never tried putting it in acid. Yet, the cleaner we get the acid nature of our stomach totally changes. So it might not be a great example of what goes on inside of everyone. I’d heat it for at least 20 min, but you could experiment with that.

  17. Rohith says:

    What about sprouts? are they mucus forming

    • Spira says:

      Some of the more starchy sprouts might be slightly mucus-forming. The less starchy ones, like alfalfa, are relatively mucusless. During more intensive cleansing periods I would probably avoid the sprouts that I know are more starchy.

      • Alex says:

        But isn’t alfalfa very rich in proteins and fat ?

        • Spira says:

          It is not high in fat that I’m aware of, and “protein” analysis is not really a concern. After performing “mucus-forming foods” tests like the ones described by Ehret, they are mostly mucus-free and seem to eliminate well. As Ehret points out, we cannot rely on “food value” concept alone when determining the usefulness of a food item on the mucusless diet.

          • kell says:

            What kind of spices/herbs and oils are recommended and also Celtic Seasalt is unrefined I use that to flavor up my foods is that accepted

          • Spira says:

            Greetings Kell,

            I tend to keep it simple and use onion and garlic powder the most. Oregano, thyme, and other aromatic herbs are also nice. From time to time I’ll use chili powder. I’m not a fan of any kind of salt and avoid using it for food. Kelp powder, dulse flakes, or celery powder/granules can be a good substitute for salt.

            Hope this helps.

    so, that list was petty much every food there is other than fruit. and one post says of course even fruit eventually can be mucus forming in the long run if not suggested properly ( and my stomach has been backed up lately but I can’t eat yogurt or anything so I dont know what to do)
    and if we can’t eat any of that stuff, What in the World am I supposed to eat? :(

    p.s please be through, I could hardly come up with a healthy meal idea when all of these things listed were an option.

    • Spira says:

      As mentioned in another comment, nowhere do I suggest that this list be viewed as a “forbidden foods list.” It is an objective list that identifies mucus and acid-forming foods. As I mention above “Ehret’s TRANSITION DIET will show you how to use less harmful mucus-forming foods to get off of the worst ones. Pus and Very Mucus-forming foods should be avoided from the beginning if possible. But Moderately or Slightly mucus-forming items may be used effectively during the transition.” The key is always the “Transition Diet,” and this list, along with the mucusless foods list, is simply a tool that can be used by people who are endeavoring to transition to a more mucus-free diet. See the Mucusless Diet ( for a much better understanding on how to use this list. Peace, Love, and Breath!

  20. Duncan says:

    I appreciate all the time you spent researching this topic. I do feel that your “list” is a bit over the top. If I was to follow your list of foods that should be eliminated from my diet, I would be able to eat virtually nothing. I would also probably become horribly malnourished. Although, I really do enjoy reading about these “extreme diets” such as the paleo diet, Atkins, etc. The important thing to remember is that keeping food intake in moderation is key. Too much of some things can lead to not enough of other things…

If you were to read the Mucusless Diet carefully, you will see that it is by no means an extreme diet. However, many people fail to understand the “transitional” nature of the diet and try to be mucusless right off the bat, which is not what Ehret or I recommend at all. Peace, Love, and Breath!

  21. Adi says:

    What about the gelatin used to wrap herbs and natural mucus free vitamins-could this be a source of disease and mucus?


    • Spira says:

      Yes, if that is the path one wants to take, plant-based caps would be the way to go. However, most mucusless diet practitioners pride themselves on being as “natural” as possible and avoid the use of processed supplements. They would rather “eat” the herbs on a salad than in a capsule.

    Prof Spira: Any feedback regarding Goji Berry, Spirulina, Chlorella and other sea algae “Super-foods”, from a mucus-less/acidic perspective?

    • Spira says:

      Goji berries are mucus-free. I’m not fan of spirulina or chlorella. Most people use these items as “nutritional” supplements, and Ehret’s work challenges the foundation of such theories and approaches. They do not aid with the removal of cellular wastes, thus they would not be looked at favorably by most mucusless diet practitioners. The only sea vegetables that I find useful are dulse and kelp. I like to put dulse on top of my salads and periodically use kelp granules instead of salt.

    I’m hoping to find a diet and lifestyle to guide my wife and i back to much improved vitality. I am reading Ehret’s book and have found this website to help along with your book, but I am also counseling with a naturopath/herbalist who studied extensively Ayurveda and the food diets based on the 3 dosha body types.

    Could you tell me how you feel about Ayurvedic nutrition and if it is agreeable with your views?

    Thank you.

    • Spira says:

      Greetings Steve, sorry for the delayed response. Ayurvedic nutrition does not correlate with the mucusless diet very well. From what I’ve read, there are many foods that are considered to be the best that are considered the worst from a mucusless diet perspective. Although, the idea of a specialized transitional approach for each person is important in the mucusless diet, the way of thinking about food and why we eat is totally different from Ayurveda. From a mucusless diet perspective, mucus-forming foods need to be systematically transitioned away from over time. And pus-forming foods should be eliminated as soon as possible (meat and dairy). Overall, I’m sure there are some useful principles and wisdom that can be found within the system’s texts, although I disagree with much of what I read. Peace, Love, and Breath!

    I have be aware of the first book by the author . I was introduce to the muculess diet healing system over 20 years ago. I was in college . I started the practice and continue today with some personal changes. But there was then and still is a question about the statement the Professor made in the original book . He stated the ” white race was an unnatural sick ” race . His justification was related to the color and mucus . I don’t have my copy of the book now , so I don’t remember the page number ,but I am sure you will find the passage about mid way into the original book . I would like to know your opinion on he logic and reasoning for such statement.

    • Spira says:

      Greetings Adi! Thank you for your question. I do not have the space to get too deep into a discussion about the subject here in the comment section, however I will share a brief explanation from the Annoated, Revised, and Edited Mucusless Diet: “Ehret’s proposition is that skin color and other physiological traits primarily reflect the degree to which a person is internally encumbered with waste on the cellular level. It challenges the popular notion that the radical physical morphology of humans occurred based primarily on adapting to non-tropical climates further away from the equator.” My notes on the role of iron in the blood and my clarification of Ehret’s discussion of eugenics from the Annotated version are also helpful. If you want to have a serious discussion about this, I’d recommend joining our affiliate program and attending an online meetup. These are the kind of topics that we examine (affiliate info). Peace, Love, and Breath!

      • Adi says:

        Well Put. The explanation is more expansive and softer than the Prof , less crude . Thank you for the more gentle approach to the subject of internal and external factors related to skin color and nutrition , including geographical locations of our ancestors. I have always believed that Power equals Vitality Minus Obstruction , but was a little concerned about the statement in the original Mucusless Diet Healing System , Arnold Ehret.

        I am Adi

    Enjoying your wonderful information. Please continue sharing. Just bought your e-books. awesome. My question – how do you properly cook a sweet potato. Thanks.

    • Spira says:

      Thank you for the kind words! My favorite way to cook a sweet potato is to back it. I might put it into the oven at about 425 and let it bake for 40-60 minutes, or cut it horizontally (like chips) into thin round pieces, put it on a baking sheet with some oil and spices placed in the oven for about 15 minutes, take it out and flip with a spatula, and then put it back in for about 10 minutes.

  27. Alex says:

    Hello Prof. Spira, thanks for your wonderful work !

    What do you think about lacto-fermented food like beet lacto-fermented juices ? It transforms the starch in grape sugar and was advocated by Ann wigmore ?
    What do you think about isotonic sea water (Quinton) ?

    • Spira says:

      I am not a fan of cultured or “lacto-fermented” foods. They are acid-forming and to be avoided as far as I’m concerned. In nature, we prefer ripe fruit over rotten fruit. Why would we want rotten “cultured” foods unless our taste buds are craving something unnatural and acidic? And I’m not a fan of using sea water solutions, particularly for nasal irrigation. I used saline-based things in my nose before the diet, and on the diet there is no use for such a product.

  28. Alex says:

    Thank you, it seems that René Quinton saved a lot of people by injecting them isotonic Sea Water which is very close to the blood serum.
    Some people like Jehovah witnesses refuses to have blood transfusion and use Quinton serum instead.

    • Catharina says:

      Hi! My dad gas low blood count and need extra iron. Could this be helpful? The state we live in won’t give him blood until the blood count is at an absolute minimum. …

      • Spira says:

        From our perspective, systemic cleansing and healing are necessary to overcome such issues. There are many people that have used mucus-free healing and fasting to overcome such issues.

        Peace, love, and Breath!

    I am eliminating foodsthat cause me to have mucous such as dairy and wheat. I am now eating more re vegetarian but enjoy wild caught salmon but now come to find out is mucous forming.

    I am at a loss as to what to eat now! I only weigh 118 lbs and am not wanting to lose anymore.

    Maybe I will try eating the bark off of the trees around us.

    Hello Dr Spira
    I am 40 I’ve been suffering from bad breath, stuffy, runny nose, coughing cause by excessive mucus for years and years
    I’m wondering how to heal this
    please would you be able tell me what to do
    Thank you

    • Spira says:

      First, closely read the New Annotated Mucusless Diet Healing System: The foundation of what you need to know in order to heal yourself is in the book. And read it with an open mind and willingness to work. You must clean out your system, which can be down with mucus-free foods, short-term fasting, and a few other therepies. Check out the book, and if you feel you need some one on one coaching, check out our consultation services here:

      You can do it! Just got to commit yourself to make the change, follow the principles outlined in the book, and follow through! Let me know if you have any further questions.

      Peace, Love, and Breath!

  33. Antonio says:

    Prof. Spira
    I would like to better understand the acid section. how can I determine if a substance is acidic and how does that affect the body? I understand that coffee should be avoided. I have gone through a huge struggle getting off it and find it more addictive then alcohol or even cigarettes. on the other hand I don’t feel like tea is addictive at all. With coffee I couldn’t stop myself from having another cup but with tea I can just have one cup and not crave anymore. so what makes tea acidic? is it the ph value or the caffeine that is problematic? what about things like cold brewed tea? that is supposed to have much lower acid content. and what about Japanese matcha green tea. I have a tin of relatively high quality matcha and it is much less bitter then regular green tea. the higher the quality of matcha the sweeter it is supposed to taste. to me it doesn’t seem acidic it tastes similar to drinking spinach juice or something like that. it also has like 10x more theanine than regular tea, witch is a substance that is supposed to counter balance caffeine. hope you get back to me. Im also curious about a bunch of Chinese herbs and tonics that are not classified in the diet. I would like to know how to determine if those are acidic.

    • Spira says:

      Greetings Antonio,

      Tea is much better than coffee and can be used on the transition. Herbal tea is the best, as it can be alkalizing if the right herbs are used. Conventional tea is just mildly acidic, but not the worst thing in the world to use at all. The caffeine is a stimulant that can harm the nervous system or endocrine glands over time, and it’s best to get your stimulation from fresh fruit or fruit juices. But, like I said, it’s okay for the transition and better than coffee. There are a lot of different types of tea and some may be a bit less acidic than others. In the long run, it is not something I would want to plan on using forever.

      You could get PH papers and do some of your own testing. Make the tea from an herb you want to check out and see where it is. Yet, results are not always perfect unless you have great equipment. And, it is hard to test how the acidity intensifies within the body (or in the case of acid fruits, becomes very alkaline when digested). So, I would get some PH papers and experiment a bit. But overall, a good rule of thumb I use with items in the herbal kingdom is to stay away from things that seem kind of addictive. That usually indicates to me that it is something that will be antagonistic in the long run.

      Peace, Love, and Breath!

    Is primerose oil mucus forming? I have been taking primerose oil tablets for approx a week and have noticed alot of mucus in my throat. Is this normal?

    • Spira says:

      The oil, which extracts fatty-acids from the seed, may be mildly mucus or acid-forming. In small quantities it is probably not going to create a bunch of slime, but from a Mucusless Diet perspective, there is not really a good reason to take it. We are not concerned with “nutritional” concepts and supplements, as much as we are with using things that will help eliminate wastes. In the herbal realm, herbs that promote increased circulation and expectoration may be very useful, along with certain essential oils of leaves that particularly sooth the nervous system in cases where people are revitalizing endocrine glands.

  36. healthy life says:

    Hi you have bananas in both to have and not to have ie mucus forming?

    • Spira says:

      Very well-ripened bananas (very yellow with black dots) are mucus-free, but “unripened” bananas (green skin) are starchy and potentially mucus-forming.

  37. healthy life says:

    Thank you about the bananas :) I am asthmatic so I always thought bananas was bad for me. I have had a fever and sinuses inflammation for the last week. I find eating nuts and cheese aggravates the situation. So definitely going to give your way a try for the next six months. Anyway Another ? , Where does mushrooms fit in ?

    • Spira says:

      I’m not particularly a fan of mushrooms. They do not aid in elimination and have the potential to be acid-forming. Also, in general our body wants to eliminate fungus when possible. If not, we can have a host of issues. Overall, if they are put on a salad I don’t think it’s a big deal. But, I wouldn’t go down the “mushroom-steak” type of road. And on days while being totally mucus-free, I’d probably leave them off the salad.

      Peace, Love, and Breath!

  38. John says:

    Hello. So, going on over a year now I’ve been dealing with digestive issues consisting of upper abdominal tenderness, (like when I lay on my stomach or push with my hands i experience some moderate pain), loose stools, constipation, my stool smells funny, undigested food particles, white coating on my tongue, more frequent urination, and a few others. I saw a doctor and I was advised to drink miralax and eat fruits and vegetables until I achieved a normal bowel movement. It helped remarkably, but I couldn’t stick to the diet long enough because I’m stubborn like most ppl. My diet prior to my digestive problems consisted of Convenience foods like soda, fast foods. Honestly all junk food. I’m 22, I work in the electrical field so I’m tend to buy a lot of foods that are on the go and already prepared. My main breakfast I used to buy from a gas station near my home on my way to work every morning was pizza and Mountain Dew. Every weekend I would go out drinking with my friends. So I strongly believe that constant soda, fast foods, coffee, and alcohol may have led to a congested, mucus filled, impaired, digestive tract. Garlic, fruits, and vegetables are the only things that improve my stools appearance, smell, and size. Once I start eating processed junk food, my stools immediately look bad again and my symptoms come back. Do you think I may possibly have an over abundance of mucus and that the mucus less diet will help repair my digestive tract? If so, how long does it usually take to fully repair and eliminate the build up up mucus and toxins from the body? I’m not planning on eating junk food immediately after healing myself but I want to be able to enjoy an occasional piece of pizza or a piece of cake at a family members birthday party instead of looking like some stuck up health freak that’s “too good for junk food”

    • Spira says:

      Greetings John! You can basically take the Mucusless Diet Healing System as far as you want or feel you need to. Many of my friends practice it as a lifestyle, but traditionally many people used it short-term to heal themselves of chronic illness. The length of time it would take for you to heal can not be determined ahead of time, as many factors are involved, including you physiology type, how aggressively you detoxify, etc. Definitely read the Annotated Mucusless Diet to check out the system. The key is learning to TRANSITION gradually, so that it does not feel like a shock to your system. If you ever need a private consultation to get a bit deeper into your specific case, check out our coaching packages HERE. Peace, Love, and Breath!

    How about ginger or dried ginger (with no additives)? It’s not mentioned in the annotated MDHS book.

      Ginger is mucus-free. When added to juices or herbal formulas, it can aid in circulation to a certain degree. I’m a fan of adding it to fresh juices.

  42. Ginger says:

    Hey spira! What about drinking apple cider vineger as a cleanser for killing body parasites and stuff? People usually drink it in the morning to wake up the body, saying it works like lemon water. Also, what about almond/hazelnut milk?

    do we really need a transition diet , can we just not jump into something that is just so simple and natural for our species, why we need always to make things more complicated!!! craving toxins ok just breath deeply and stick on what is best for us… get out of u mind and listen to u body

    • Jei says:

      I recommend that you read Ehret’s works to understand why a transition diet is safer and often necessary for the average person.

      In short, going straight from mucus-rich diet to mucus-free diet can overload your body as the accumulated gunk is broken down and attempting to get out. This can cause aggravated illness and death as your body is clogged by a lifetime’s worth of mucus and pus.

    Hello, I had a bout of pneumonia a few months ago. And I still feel mucus buildup of my left lung. It feels like it gets stuck there. It sometimes comes up. Can you recommend the best foods for the lungs? or other tips

    • Spira says:

      Greetings Cynthia,

      I’m sorry to hear about your mucus challenges. To give you the best advice and guidance for your specific situation, I’d need to know more details about your past/current eating habits, physiology, ailments, etc. This is information that I’d learn through the questionnaire I’d send you before a formal consultation. If you are interested in a one-on-one session or group of sessions, here is a bit more information on my consultation services: With that said, there are many things that can be done to over come your symptoms. Definitely check out the Annotated Mucusless Diet for details about the transition diet and fasting: It will answer a lot of questions. There are also a handful of herbal formulas that can help get things moving while systematically combined with fasting and mucus-free diet that I usually go over during consultations.

      One thing that could help a great deal is lemon juice enemas, which many mucusless diet practitioners use. Clearing out the slime in the colon can sometimes give immediate relief.

      Thanks for reaching out and let me know if you’d like to talk one-on-one.

    HI! So how do you feel about Irish Sea Moss? And herbs like burdock, dandelion, yellow dock, saw palmetto, and red clover? Plus I’ve read seemingly more studious and scientific articles that convey that Apple Cider Vinegar aids in cleansing the blood and breaks up mucus throughout the body, cleansing the lymph nodes and improving the immune system–the fighter of disease. Also, doesn’t your stomach acid make anything acidic? And then other excretions that are more basic allow whatever was eaten–no matter what–to pass through the small intestine for absorption? In other words, how could something possibly rot in your large intestine, as I’ve heard you say before, when it’s all broken down into readily-absorbable nutrients in the stomach and absorbed in the small intestine (with the exception of indigestible fiber of course)? The only thing that rots in the colon is indigestible fiber, and I’ve read that this is actually good for gut flora. What of fat soluble vitamins? How can you absorb Vitamin A, D, E, or K without fat? Do you promote any herbs? And do you eat raw kale? And do you think vitamins and enzymes don’t matter? Do you think all we should ingest is glucose-fructose cultivars? What do you think your ancestors ate? Do you think carnivorous shamans are more spiritual than you? Do you think our disconnect from the gods is the root cause of all this evil? Do you believe in the gods? How much don’t you know? Why do we even have teeth? Canines? Why do we have brains made up of fat? Why isn’t the body totally alkaline? Why does duality exist and why am I asking you? Do you know what phytate is? Have you ever spoken of actual chemical processes or do you only say stuff like “pus is the product of the digestion of animal flesh”? What of minerals, man?!?! What do you really eat? Do you starve yourself of anything that can be ingested via mouth? Is the ultimate goal to be so light that you’re 3-D body dissipates into your soul which was already inhabiting your body? What of astral travel? Isn’t it just as possible for a round-bellied person to have a spiritual experience? Do you think you could be over-occupying people with the physical world and bodily thoughts and stunting their metaphysical faculties? Please answer all of my questions. Or just the food related ones. I apologize for ranting. Thanks!

    Prof. Spira,

    I tried to let get of the following question but it just keeps haunting me in my dreams (since all of my waking hours are currently spent in the mucusless state :), but it had to be asked at last…

    Why do you recommend eating avocado with a salad (if it’s has to happen), while nuts (and seeds, like chia?) should be combined with low water content dried fruit? Logically, both avocado and nuts / seeds are best consumed with leafy greens? Or both with dried fruit?

    Actually, I am still unsure when Ehret recommended high fat / high protein items with high carb dried fruit – the ‘low water content’ argument doesn’t seem to hold water from my point of view (pardon the pun).

    Enlighten us, Plebeians, with your knowledge, good Sir!

    And thank you for the inspiring and life-changing work :)

    • Bob says:

      why* Ehret recommended

    • Bob says:

      Also forgot to ask about coconut meat – if it’s really really young, then it shouldn’t really be mucus-forming, right? There’s barely any fat in it…

      And if it is slightly fatty, would you advise mixing it with dried fruit or leafy greens or simply fruit for optimum digestion?

      Many thanks once again, Professor.
