I came upon this clip a couple of days ago:
SecretsOfLongevity speaks against 80/10/10, to which I comment that people fail when they don't fully pay attention. I also remind him that his bland setup and quick verbal pace is a stressful mix - although, I must admit, I was probably wording it in a more provocative tone.
In the comments, you can probably spot the conversation I had with him. He keeps referring to other videos, while I try to keep him on track with the first one. When I finally look at one of his other videos, where he is debunking snake oil, I ask him how that is relevant to a discussion about the 80/10/10 diet. I was blocked.
I believe it proves that when a salesman is challenged and has no counter argument, and fails when pushing more of his own products, his circuitry starts frying.
Perhaps I was being harsh. I didn't mean for my comments to come across that way, but writing is an obscure element, and unfortunately it is often read with skeptical eyes.
I'm not totally opposed to superfoods or supplements, but not a single person has yet convinced me of the advantage. It is pretty darn difficult to argue against a ripe banana.
