Indy51, going to listen to it now. Thank you!
Interesting, particularly the information he provided on constipation, but I had problems with a lot of what he had to say.
He made three statements:
1. Fiber is not a necessity for a healthy diet
2. There are some low carbohydrate foods which commonly cause bloating and other symptoms, and we can identify these and improve gut symptoms on a low carbohydrate diet.
3. There's simply not enough evidence that altering our gut bacteria can lead to weight loss.
I've wondered for some time how the microbes in the microbiome are fed and nourished on an animal protein and fat diet only. He didn't address this question. He simply said that ketones better supply the cells that form the barrier between what's in our colon and what's in our blood.
He totally lost me on the non-celiac gluten sensitivity isn't a gluten problem, it's a fructan problem - (one of the FODMAP types of foods). Well, I have NCGS, experienced bloating until I gave up gluten, and I eat most of the fructan foods he listed and experience no bloating. I really am frustrated with the Australian's about their argument that NCGS is not due to gluten, it's due to one or more of the FODMAP foods. In my mind you can have one or the other or both.
Also, initially he talked about inflammatory bowel disease, then as soon as he began talking about FODMAP, he switched to irritable bowel syndrome. They are very different conditions. I have IBD and have never had IBS symptoms.
As for the weight loss discussion, we know the low carb diet helps many lose weight, but the problem with fecal transplants is to sustain the benefits, I'm going to speculate that you have to know what to eat to keep the desirable microbes fed and happy.
There was a gem in there though. What was the ingredient used in foods like ice cream that was introduced in early 2000? Could it really be cause of the increase of C. diff infections? I need to go back and hear what that ingredient is. [Found it. At minute 21:12 he begins discussing this study or article, Dietary trehalose enhances virulence of epidemic Clostridium difficile". And here's an article that explains when it's important to avoid eating foods that contain trehalose...

Quote from article:
For most people most of the time, there’s no need to avoid foods containing trehalose. Under normal circumstances, helpful bacteria in your gut outcompete C. diff, preventing illness.
But a great danger exists when you have a serious infection treated with “broad-spectrum” antibiotics, especially the kind that is serious enough to land you in the hospital. Those antibiotics wipe out helpful gut bacteria. Take action: Read ingredients lists on all packaged foods you eat, and avoid any that include trehalose while you are taking such antibiotics and for several weeks afterward. And avoid trehalose if you have or have recently recovered from a C. diff infection.
I was most interested in his first statement. Managing constipation is important for health, but that's not the only reason I eat nutritionally dense, fiber rich plant foods.
I also find it amusing that I only have problems with constipation ON the LCHF/Keto diet! I don't know what I'd do if I didn't take magnesium daily.
Fiber and the microbiome is a subject that I'm intensely interested in. If you come across more, please share them. Complaints aside, I really did like the first part of his three part presentation. Thank you.
