This list is going to be a little longer than the last. You cut out all sugar (both real and all substitutes whether natural or artificial, like honey, maple syrup, Splenda, etc.). No grains, legumes (including all forms of soy), dairy, or alcohol. You’re also told to avoid additives like MSG and carrageenan, although that should happen naturally if you’re sticking to whole foods.
With a very simple shift we not only remove the foods that are at odds with our health (grains, legumes, and dairy) but we also increase our intake of vitamins, minerals, and antioxidants. Here is a great paper from Professor Loren Cordain exploring how to build a modern Paleo diet: The nutritional characteristics of a contemporary diet based upon Paleolithic food groups. This paper also offers significant insight as to the amounts and ratios of protein, carbohydrate and fat in the ancestral diet.
When you open the can, the cream will have risen to the top and become solid, while the coconut water remains at the bottom of the can. Just scoop out the thick stuff at the top and use it in recipes that call for coconut cream. You can also find prepared coconut cream or “culinary coconut milk” at some health food stores, but why would you pay extra when the only thing required to make your own is opening your refrigerator?
Another downside: If you have had chronic health issues (especially gut related), you may find that reintroduction actually teaches you that you're sensitive to most foods. It turns out peanut butter, gluten, and most dairy are now off limits. That rots!! But I'll live. I feel so, so much better without them, as I learned. And wouldn't you rather know why you feel crappy all the time?
The data for Cordain's book only came from six contemporary hunter-gatherer groups, mainly living in marginal habitats. One of the studies was on the !Kung, whose diet was recorded for a single month, and one was on the Inuit. Due to these limitations, the book has been criticized as painting an incomplete picture of the diets of Paleolithic humans. It has been noted that the rationale for the diet does not adequately account for the fact that, due to the pressures of artificial selection, most modern domesticated plants and animals differ drastically from their Paleolithic ancestors; likewise, their nutritional profiles are very different from their ancient counterparts. For example, wild almonds produce potentially fatal levels of cyanide, but this trait has been bred out of domesticated varieties using artificial selection. Many vegetables, such as broccoli, did not exist in the Paleolithic period; broccoli, cabbage, cauliflower, and kale are modern cultivars of the ancient species Brassica oleracea.
Research into the weight loss effects of the paleolithic diet has generally been of poor quality. One trial of obese postmenopausal women found improvements in weight and fat loss after six months, but the benefits had ceased by 24 months; side effects among participants included "weakness, diarrhea, and headaches". Any weight loss caused by the diet was merely the result of calorie restriction, rather than a special feature of the diet itself.
Looking back on my lifestyle before the Whole30, my personal recipe for making unhealthy food choices typically consisted of being hungry and on a time crunch, which meant I'd choose whatever was most convenient (read: something overly processed from the vending machine). "Whole30 requires you to plan ahead, mainly so you stay 'compliant' and don’t go hungry," explains Liz McMahon, RDN. "Planning out meals and batch cooking ensures you have healthier food available and won’t constantly be reaching for fast food options." Making pre-planning a habit — even when I'm dining out — helps keep me on track even when I'm not following the Whole30.

In Defense of Food: An Eater's Manifesto by Michael Pollan gives a guided tour of 20th century food science, a history of "nutritionism" in America and a look at the marriage of government and the food industry. Then the book presents a commonsense shopping-and-eating guide, which like the paleo diet focuses on shopping the perimeter of the supermarket. He also now has a much shorter Food Rules: An Eater's Manual.
A few days ago I was delighted to learn that Dr. Oz was going to again feature The Paleo Diet on his nationally syndicated television show along with one of my co-authors, Nell Stephenson, of The Paleo Diet Cookbook. I tuned into the Dr. Oz show and was happy about most of what I saw except for Chris Kresser, expounding upon the health virtues of a food group, beans and legumes, that definitely are not Paleo. Please read the following...
"We settled, because I don't want to spent 50 to 75 grand getting sued," says Jason Janke. "I covered up the sign." Saran, CrossFit's general counsel, says it's all part of the fight against "the road to genericization." If people can sell "CrossFit equipment" the way they sell "baseball equipment," says Saran, then it becomes crossfit. Soon anyone will be able to coach crossfit or promote a crossfit tournament--effectively killing the value of being an official affiliate, or being CrossFit, for that matter.
