Where did you learn it’s not backed up by science?

Leaky gut by definition is intestinal permeability. Mayo, Harvard, John Hopkins and Cleveland medical institutions all state this. That means the lining of the intestines has broken down allowing bacteria and toxins to leak through the intestinal wall. So it’s real. What is not understood by these medical institutions is how or if this is the cause of diseases.
I agree Dr. Gundry is a scam in terms of trying to sell his products. Foods he believes should be omitted also baffles me. One example is avocados that are highly nutritious. There are others like him who have these 30 minute videos and in the end talk about why you should buy their products. And in my opinion there’s nothing unique about their products that you couldn’t find elsewhere.

Yes… 🙁

There’s an excellent book, SUPER GUT by Dr. William Davis, you can get on Amazon. He talks about tests you can order yourself for SIBO or other concerns you may have, foods to include in your diet, prebiotics and probiotics as well as recipes. There are so many illnesses that are triggered by the lack of a healthy gut biome. It’s worth the read.

I fell for it and they got me for about $500. It is a total 100% scam from my experience. They doubled my online order “by accident” and changed my card the full amount for both orders, I called customer support about the mix up and after a very long hold a very pleasant young lady assisted and assured me that all I needed to do was return the extra merchandise (I would be responsible to pay shipping both ways) and that the refund would show up on my card between 30 to 60 days. She actually laughed a few times while assisting me. She also advised me that I would end up needing the doubled order anyway because the best results occurred over a longer period of time. I kept them and took the probiotics as directed 4ea daily for 120 days with absolutely zero results.. not even a slight placebo in the beginning etc. I could have bought an awful lot of sauerkraut for $500, what a rip off. The best probiotics you can get are in organic plant based foods. It turns out that all of my low energy, bloated gut and digestive problems disappeared after 45 days of abstaining from drinking beer or any other alcoholic beverage.

In answer to the original question, Dr Anthony Fasano discovered Zonulin, which regulates the trafficking of environmental antigens across the mucosal barrier. A web search should bring up details.

I believe that is related to leaky gut, but may not be exactly the same.

Gundry is a CON MAN!

Some notable medical research online suggests that “leaky gut” is not taught in medical school. It could mean that one needs to see a Gastroenterologist who could make a legitimate diagnosis.

Yes, I think so.
I ordered a 6 month supply of microbiome pills on July 1, 2023.
I have been taking 2 twice a day since then.
I haven't noticed any difference in my health or my elimination patterns.
Furthermore, I think they were somewhat expensive.
And having read some of the copious junk mails that I was receiving, I started thinking not even half of this can be true. It's more like he's trying to start a hysteria about food choices than using any common sense.

So then I tried to opt out of all the Gundry emails. More than once. I still have one pesky notification coming through on a regular basis from this email address: < newsletter> I finally had to create a filter for disposing of emails received from this email address.

Even if the pills were doing anything for me, I still find the relentles marketing very annoying.
I started a personal swimming program back in early May, and in my opinion that has done a lot more for me than any pills. I'm steadily firming up and losing weight and my appetite is steady and reasonable. My breathing is very good. I'm less winded going up staircases.

I think that could have saved myself the $300 that I spent on the pills. Wasted money. I still have 3 months left (because though I ordered them in July, I didn't start taking them until August, and I plan to continue taking them, but after 3 months with no visible changes, I'm not holding my breath.

Hope this helps anyone else who is thinking of joining a Gundry Program.

Hi, @tokyok. What I have found most disconcerting about this and a half dozen other "expert professional" advertisers (most notably Dr. Gundry and Sanjay Gupta) is that they undermine information about a number of medications so that their ads ultimately address "the only solution that works." Of the solutions they blackballed are a number approved by the FDA and the American Medical Association and foundations established by groups of medical specialists to expand the use of reliable medical diagnoses and processes across the nation, including the victims of the rifle-shot ads that are paid to mislead, even lie to, those of us in need of considering the full range of help from organized medicine.
