I keep the seed oils out of the house too. But of course, you can't completely avoid them.

But the body has the ability to take care of itself, as long as you don't overwhelm it.

And I don't think just because a person calls himself/herself a doctor and writes a book, means that book is the bible. It could be a covert advertisement, or written in good faith. It could work for one and not the other or nobody at all.

Gather from many sources, and see what works for you.

I tried a few different diets, some of which have stellar reputations, but didn't work for me. When I found the Ketogenic diet, it did. Decades later, it's still working. Plus, I'm healthier than probably 90% of the other folks my age.

Will it work for everyone? I doubt it. We are all different.
