I spent the last few days with Jack LaLanne and Paul Jaminet...well, their books anyhow.
In Jack's last book, Live Young Forever, which he wrote a year or so before he died at age 96. In the beginning, he says something like, 'don't just skim this book, read it carefully, these are my thoughts on health and fitness from observing people for 95 years.' Besides a grueling workout regimine he kept til the end, he ate whole food and didn't compromise. He ate grains, but not flour. He ate potatoes, but not with butter and sour cream. I don't think he mentioned carb-fat-protein in the whole book, which was a breath of fresh air!
In Paul Jaminet's new Perfect Health Diet, with an intro by Mark Sisson, he recommends everyone eat 1-2 pounds of potato, sweet potato, rice, plantain, or cassava, AND 1-2 pounds of veggies/fruit, AND 1 pound of meat. His DO NOT EAT list is short...vegetable oil, grains, beans, and sugar. Everything else is allowed to some extent.
Since rice is a grain, I'm surprised it made his safe starch list, but at any rate, I think we are being steered toward a diet that is 1/3 starch based. Notice I didn't say 'carb based', but starch based.
I am leery of rice, and eat it sparingly. I think sweet potatoes and potatoes will be the new "Big Ass Salad" of the PB future.
In his intro to Perfect Health Diet, Mark Sisson says "I am a generalist, Paul Jaminet is a scientist". I think you guys might be ahead of the game if you get a copy and read it.
When discussing keto and low carb diets, Paul Jaminet still wants us to eat potatoes and rice while on these diets. There is 'stuff' in potatoes, sweet potatoes, etc... that is vitally important to our health. It's way bigger than glycogen and insulin.
