    I received a FMT ( fecal microflora transplant) one month ago! I had a bacteria infection, took an antibiotic to get rid of it (C Diff bacteria)! I have no more C DIFF spores 🌝 Now that I have brand new gut bacteria, I am living ,and eating to feed THEM ❤ I feel like a new person mentally, physically, and spiritual!!!

    I'm a formula fed 70's child FUT2 non excretor. Suffered ADHD, numerous illnesses, addiction issues etc.. I'm finding health through organically growing my own vegetables with which to support my microbiome. Prolonged fasting has massively helped too as has cutting out alcohol, bread and vegetable fats. I make my own ferments and herbal extractions for digestive tonics. I fully subscribe to modulating your microbiome to help the physiology reach homeostasis.
  • @marthahicks8569
    The speaker gave a fantastically well-organized and concise presentation! No off-topic rambling at all. This made it very easy to follow and stay focused on the information. Great job!
  • One of THE BEST presentations on the impact of the human microbiome. She so clearly & concisely condenses this vital, newer field and its critical role in human health.
  • As an infectious disease physician who has had an abiding interest in the health and disease implications of the human micro biome for several years, I almost skipped this presentation. So glad I didn’t! Great information, well-organized and communicated in a highly engaging and compelling manner.
  • @aquamarine99911
    She is one of the best speakers I've ever heard. I can listen to her all day. Little bit of residual Irish brogue, but she's clearly been in SoCal for a long time. And doing great work!

    Diet works to address inflammation. I’ve been a private health chef for 30 years and have seen positive results in 99% of my clients in their health journey.

    Sulfite intake is directly linked to asthma symptoms and urticaria. Sulfites are ubiquitous, as they are used as a fumigant, antimicrobial agent and bleaching agent in the manufacturing/processing of foodstuffs. In the U.S. ingredients of ingredients are not required to be listed on food labels. So you won’t see sulfites listed when they are used in the processing of food raw materials. The worst offender is high fructose corn syrup (HFCS). Sulfites are used as antimicrobial “preservatives” in high fructose corn syrup at 1000 times the level permitted by the FDA as an additive, but as an ingredient of an ingredient, it need not be disclosed. Compounding this problem is the fact that many pediatricians tell parents of asthmatic children to replace milk with juice - often containing high fructose corn syrup, thus heavily laden with sulfites. Sulfites are also used as a bleaching agent in regular sugar, flour and salt. So condiments and gravy and other flour products can be a problem. Sulfites are also used in the manufacturing process of all alcoholic beverages and all sugared beverages. Additionally, sulfites are found in all frozen seafood, to prevent black spots. The food technology industry has been allowed to become insidious in renaming high fructose corn syrup and even changing the manufacturing process, making it more potent and requiring more sulfites. There is information available on the internet regarding the tested content of sulfites in foodstuffs and the renaming of HFCS. If you, or someone you know suffer from asthma it’s worth the effort to research. Most of this information regarding sulfites became known because previously, restaurants were allowed to sprinkle metabisulfite on salad bar foods, e.g., greens, veggies, fruit, etc., resulting in more than a few asthmatics having immediate lethal asthma attacks. HTH!
  • @Salmanistaan
    Wow. What a speaker she is. I watched this video 4 times and got answers to many of my questions about gut microbiome. Thank you for sharing.
  • @Biomeducated
    Simply fascinating! As a biomedical PhD student working on the Gut-Liver axis, the gut microbiome is extremely relevant for my research. I'm glad I convinced my PI to include a segment of experiments to check how the gut bacteria play a role in our models. Great things will come from microbiome research! It's still early days to come up with targeted therapies, but man, this is exciting research!
  • @roswithabed3650
    What a pleasure to hear that proactive scientists are unraveling so many causes and interactions in our own body ecosystem. 👏
  • @pogchamp7983
    It's so funny cos my sisters boyfriend (who has Colitis) reckons the doctor told them to 'not eat highly fibrous foods as their body cannot break it down and they should stick to refined stuff'. Goes to show a lot of doctors don't learn about nutrition and are just taught to prescribe drugs!
  • Very instructive presentation. This lady is gifted by such a harmonious voice and perfect diction that I would pay to listen to her reciting the content of the phone book.
  • @jetsetter8541
    I am highly impressed ! Microbiome Science is in it's very beginning stage and has the enormous potential for application in treatment of ALL medical conditions. They are a true biomarkers of most deseases. I am full of admiration for Dr. Lynch for linking different ailments with different Microbiome diversity. These studies might be awarded with the Noble Price. It is already revolutionizing diagnostics.
  • @Pmc07AyeUrDa
    I have suffered from asthma all my life and have been doing everything I can to improve my lifestyle and diet to reduce my symptoms. This lecture is mind blowing and has completely changed my view on the disease. If there was ever an opportunity to take part in clinical trials I would jump at the chance. Until then the new topic of study is gut biome health. Thanks for this great lecture!
  • For over a month I've been preparing home made keffeir a glass intially each day, now every second day. I include a healthy Mediterranean diet and I can't believe how much better I feel . This is good research presented by the lady. Thank you from Australia 🙌

    This is a little long but I think it’s kind of interesting. I was a 4oyr old nurse that had naturally been thin all my life. I could eat all I wanted and did. I was a formula feed baby. I was brought up an a meat and potatoes diet. We always has a meat (beef, pork mostly, and sometimes chichen, NO fish or NO seafood) so we always had a meat, a starch whether it was potatoes or rice, and a vegetable. I don’t remember there being any fruit in my house when I was a child. I even had a set of triplets and all the weight I had gained came right off at age 33. However, everything changed when I was 37. I have breast cancer and needed surgery and 3 different chemo medications over 4 months. I pretty much made it through okay. But come about 1 1/2 - 2 years later I started to blow up like a balloon. I was gaining weigh so fast that sometimes my abdomen ached. I couldn’t stop it. I couldn’t eat as much as a used to eat and I started eating very little but still the weigh kept coming. It hit my belly first convincing everyone around me that I was pregnant. I was not. My doctor looked for tumors or cysts like on an ovary and there was none. Just fat. I know had a fatty liver and I don’t drink. The weight still kept coming. I went from weighing 125 lbs to 200 lbs over a few years. I have been at 200 lbs for probably 4 years now. I’m currently 50. But my weight still creeps up. I will look at the scale and I will be 210 lbs and then I have to starve to death to try to get back down to 200. I have tried dieting but I get sick when I down eat. Meaning my stomach hurts, I get a headache, and I’m nauseous. So instead a try eating just a small portion of food but that only holds me at this weight, Here’s the interesting part and this is all guess work on my part. This is all so new my doctors think I crazy. Remember that I am a nurse. My specialty is working with diabetics. Almost of of them are type II which is the one associated with obesity. My glucose level has been steadily raising and I now had pre-diabetes. No doubt to become full on type ii diabetes. I had 21 patiences a day and I worked a lot of hours. If you’re thinking many diabetic nurses are thin you are probably right but there are a lot of fat ones too. Here’s what’s different in my case. I had my gut biome completely destroyed by chemo therapy. One week before I started chemo I had some kind of skin infection so the doctor gave me everything under the sun that would kill whatever was affecting my skin. I had strong full spectrum antibiotics, anti-virus medicates and I don’t remember what else. So for the week prior to starting chemotherapy I had already given my gut biome a good killing. Then for four straight months, death to my gut biome. Going back to my job. I always eat the same foods that these people eat because I never brought my lunch so i would just steal the extra trays of food. I was very up close and physical with all these patients while taking care of there missing limbs, wounds that wouldn’t heal, and all kind of diabetes ii problems they had. At times I would have to use the main bathroom where many patients also used although they were supposed to use their bathrooms in their room. I know my microbiome was pretty much wiped out. The chemo also wipes out and reeks havoc with your immune system. I think as my biome was replacing itself it did it just like when you are a child. It got it from my environment and that happen to be a diabetes ward with a bunch of obese patients and their families. I think a fecal transplant but there’s not a lot doing obesity. Most are already full. And beside I live on the gulf side of Florida. And the weigh transplants aren’t near me. Another problem is that nobody takes me seriously. My story could be a possibility. It’s not impossible that it happened sort of like this. One good thing came out of chemo. Before chemo I had restless leg syndrome so bad most nights that I would cry because i was frustrated and it hurts. It would go on so long that eventually I would be so exhausted I would fall asleep for a little while. Well, guess what’s gone for almost a decade and a half? Yep, RLS completely gone. I think that is due to the destruction that chemo therapy does to your nerve or maybe it’s an unknown virus. I have no idea but I am so glad it’s gone. I wish I could tell this to a chief researcher of RLS. It might just be a fluke or maybe it could give them a clue.
  • I would like to hear this professor's assessment of glyphosate, the ingredient in the herbicide Round Up. It kills the bacteria in our gut, on a daily basis. This is a call for the practical knowledge of this expert.
