Best Food to Prevent Common Childhood Infections

August 27, 2019


[Music] in 1989 the late Charles Janeway give a presentation that was to revolutionize her understanding of the immune system he proposed that we we must have some ancient innate first line of defense we knew about vaccinations for centuries how our bodies can learn from past infections but he figured that’s not good enough our body must have evolved some way to recognize foreign invaders the first time they invade he proposed that the way our immune cells discriminate between self and non-self our own cells versus invading microbes may arise from pattern recognition receptors we’re just born with the ability to recognize patterns of microbial structure for example there’s a unique component of fungal cell walls that naturally stimulates our immune system called beta glucan our own cells don’t produce it but fungal pathogens like Candida do Candida is a type of yeast that can cause serious blood infections so it’s a good idea our immune system recognizes it right off the bat so yeah you could stimulate your immune system injecting Candida into your veins but then you might also die luckily for us non disease-causing yeasts like sacrum I see cerevisiae which is what baker’s yeast is and brewers yeast and nutritional yeast also have that same molecular signature that beta glucan so the drug industry is all excited about capitalizing on this powerful immunostimulatory response to develop new anti infection anti-cancer therapies but yeah but does it have to be injected into the vein what happens if you just eat some nutritional yeast our digestive tract is our largest point of contact with the outside world more surface area exposed than our lungs and skin put together and so not surprisingly most of our immune cells are concentrated along our intestinal wall but they don’t just stay there once they’re tipped off – what’s happening in the gut then go off to defend other parts of the body that’s why you can give an oral cholera vaccine for example and end up with cholera fighting immune cells in your salivary glands pumping out antibodies into your saliva to protect against infection so what if we sprinkled some nutritional yeast on our kids popcorn for a snack might that help martial defences throughout their bodies adults tend to just get a few colds a year but the average school child can come down with a cold every other month and what can we really do about it modern medicine has little to offer for run-of-the-mill common colds nevertheless doctors still commonly prescribed antibiotics which can do more harm than good clearly there’s a need for effective safe and inexpensive treatments and beta glucan may be just the right solution but you don’t know until you put it to the test so researchers performed a randomized double-blind placebo-controlled trial about 1/2 a teaspoon of nutritional yeast worth of beta glucan in children who suffered from like repeated respiratory infections and after a month found a significant increase in salivary lysozyme levels compared to control lysozyme is an important protective immune component of our eyes nose and mouth but a larger follow-up study reported the opposite findings an apparent drop in salivary lysozyme levels although the researchers claimed that this was accompanied by pronounced improvements in general physical have no data is given but the only reason we care about the lysozyme levels though we were hoping it would result in fewer infections but that had never been directly studied until now the title kind of gives it away but basically a randomized double-blind placebo-controlled trial was performed to see if just a dusting of nutritional yeast worth of beta glucan a day could reduce the number of episodes of common childhood illnesses during the 12-week course of the study 85% of children in the placebo group experienced one or more episodes of infectious illness here it is graphically 85 percent got ill in the sugar pill group but just taking like an eighth of a teaspoon of nutritional you wertha beta-glucan sir or even just a sixteenth of a teaspoons worth appeared to cut illness rates in half and those on the yeast that did come down with a cold only suffered for about three days compared to more than like nine days in the placebo group the researchers conclude that by giving kids these yeast beta glucans we could decrease the incidence and severity of infectious illness during the cold and flu season and thereby benefit the parents as well [Music] you

    Awesome! Thanks again Dr Greger. I just bought my 1st bottle of Nutr Yeast this weekend. Great flavoring agent, with LOTS of good vitamins and virtually NO sodium! 😀

  • Reply Noah James Wescombe November 8, 2017 at 1:09 pm

    Most kids just don't eat enough fruit and veg, so low blood serum vitamin A and C levels. I don't think it is that complicated as to why their immune system is vulnerable — plus they are around other kids. Still very interesting though.

    I am confused now… in a previous video you tell us to stay away from yeast as it increases the risk of IBD (Inflammatory Bowel Diseases). Brewers and Bakers have a lot more IBD because of yeast. I feel like it’s not worth it to eat yeast to prevent a few benign colds when it increases the risk of developing such debilitating diseases.

  • Reply Eelke Aptroot November 8, 2017 at 1:37 pm

    Nutritional yeast definitely triggers some immune response in my body, every time I consume even a tablespoon of it, I wake up with red spots around my nose the next day, not acne, just red spots.

  • Reply Vegetable Madness Ⓥ November 8, 2017 at 1:42 pm

    nutritional yeast is not necessary though, just keep a healthy gut microbiome, which you get by following a whole food plant based diet,

    Another good study: https://www.ncbi.nlm.nih.gov/pubmed/23340963 but you don't have to buy supplments, get them from plant based whole foods. Mushrooms – particularly shiitake, maitake, reishi, shimeji and oyster varieties – are good sources of beta-glucans. In addition to promoting healthy cholesterol levels, the beta-glucans in mushrooms have been shown to boost immune system function.

    Did the study day if they were using raw or cooked yeast?
    Because, unless the good property exists because it's not active, the yeast in bread should do the same.

  • Reply Gigi Pizzuto November 8, 2017 at 2:53 pm

    It took me a while to find a nutritional yeast fortified, to get extra b12. WHYYYY they had to load it with topic acid… 230% DA. Unbelievable.

    A big request here Doc. I am suffering with dyslexia and its affecting my occupation as I find it hard to concentrate for long periods of time. Can you give me some insight on how to remedy with food? Thanks.

  • Reply Ben November 8, 2017 at 7:52 pm

    Oat milk contains beta-glucan too – but the structures of beta-glucan vary from source to source, so it isn't going to be identical to the type found in this yeast.
    Anyway, since becoming a vegan I've noticed a dramatic difference in colds. Rarely get them, and the few I've had have been pretty minor compared to before. I can't think of another possible cause for the difference so far. I still work in an environment with students and endless colds going around in the winter, I just seem to not be getting them any more.

  • Reply D Master November 8, 2017 at 8:14 pm

    so nutritional yeast works almost as well as high dose vitamin C for preventing colds and flu. but can it treat infections such as tetanus like vitamin C can. Can it treat whooping cough as well as high dose vitamin C? can it cure all acute viral infections like high dose vitamin C can?

  • Reply TheAltruismActivist November 8, 2017 at 8:18 pm

    +1 for nooch. One of the most noticeable health benefits that I’ve noticed from being on a plant based diet is my immune function (even years before I began occasionally consuming nutritional yeast). I rarely get sick anymore!

  • Reply Conscientious Omnivore November 8, 2017 at 8:44 pm

    This is great. I like adding a bit of nutritional yeast to our tofu scrambles. Not only does it give a nice flavor but apparently lessens our chance of getting sick too? Awesome!

  • Reply Tom Jones November 8, 2017 at 10:31 pm

    It seems from the charts displaced in the video that the lesser amount of 1/16 of tsp worked better than 1/8 of a tsp. Any reason why this would be true. Perhaps even LESS than 1/16 tsp would worked even BETTER? ? ?

    Can you make a video on how to use diet to help, fight, recover, and prevent lymphoma cancer(hodkins and nonhodkins). I was wondering if you has a video on it but I couldn’t find anything. So I searched online to see what foods help fight lymphoma and found nothing. Why is this?

    Candida is pronounced /ˈkandɪdə/, with the stress on the first syllable. It's the feminine form of candidus, which in Latin means white (as well as albus/alba/album. )

  • Reply JellyfishGroupStan February 12, 2018 at 4:07 pm

    so would it be safe to infer that the reason many vegans are sick so infrequently is due to consumption of nutritional yeast?
