This article is full of silly things. I'd take any advice given in it with a pillar of salt.
Serious alarm bells should be ringing in your head:
The article itself, "I am NOT a licensed nutritionist and I strongly urge everyone to consult a doctor before making any major changes in one's diet."
One of the sources cited, "Dr. Michael Lam, who specializes in natural healing"

"Are you confused about the nutrition information you hear about these days? Seems like we hear something new every day and it is hard to know who to listen to. Next time someone gives you nutrition "advice" ask yourself "what are the credentials of this person giving me this advice?" A nutritionist is typically someone who completes an undergraduate or graduate degree in nutrition. They may be working as a research scientist, health and wellness educator, professor at a university etc. Be aware that there are individuals who market themselves as "nutritionists" with very little or no training whatsoever in nutrition. They may be selling "nutrition products"at a health or fitness center . Before you take "nutrition advice," be sure to check out the professional background and training of the individual giving it."
