Duh!
Not that hard to figure it out after you've skimmed through a few too many magazines.

That's why if a person wants to use a supplement, just buy basic ones like whey (pure ones if possible), creatine, vitamins, fish oils, glucose.

I've read the Vince DelMonte book.

He didn't suggest no supplements at all. At the nutrition chapter, he did suggest whey and multivitamins, but heavy emphasis must be from natural & whole foods.

This is just the first part where he debunk the myth about relying on too much on supplements and the relationship between magazines and supplement companies.
When writing a book, an authors sometimes need to make some blanket ideas to kick start a noobs mind.

LOL! Hah hah!
Give the guy a break. He's learning along the way. So a change in his thoughts and direction is normal.
We all thought we were right once, then slowly as we pick up new information... we change our stance. Some do it subtly, some more public.

At least he isn't Budak84.
