You can get plenty of fibre (I'm from the "roughage" generation) from totally natural or minimally processed foods. Again, he threw potatoes into Dante's Inferno. Bonkers. Steamed, skin-on or baked potatoes are nutritious. Not convinced at all that you need to buy his heavily-processed space fillers in plastic bags and boxes.
I caught 5 minutes, during which Ellis mentioned that she was going to show us how to get involved, that they'd done the prebiotics, were going to do the probiotics, show us how to get involved, then do the collagen and finally show us how to get involved. Pretty sure that all three have dubious real benefits and border on being a useless, scaremongering scam. If you eat a varied diet with plenty of natural fibre, you don't need the worms or either of the "-biotics" (one produces the other, naturally).
He might have a point about seed oils (use fruit pressed oils, such as olive oil, and butter). Again, though, this is largely a generation thing. He will have been brought up by a generation influenced by those who endured WWII and rationing, where any form of fat was scarce, and food producers were encouraged to grow crops for sustenance as much as for nutrition. Yes, margarine should probably be avoided but it was created for a very good reason. Manufacturers of Ultra-Processed "food"s - where high levels of fats, emulsifiers, salts and other chemicals are used - ought to be worried. Nowadays, particularly recently, cooking in the home can be done with gadgets designed to use less added fats. There is a quiet revolution going on in the home kitchen, I think. I still think the answer is information sharing and not producing highly-processed alternatives.
Off to just check that I remember how I can get involved. Absolutely.
