Still, many scientists have expressed concern that we do not yet have enough evidence to make any strong claims about the paleo diet’s health benefits, especially its long-term effects. In fact, in an article in response to the first review, authors Tanis R. Fenton and Carol J. Fenton, from the Cumming School of Medicine in Canada, wrote a letter to the editor in which they expressed their disappointment with the review. (5)
Advocates of the diet argue that the increase in diseases of affluence after the dawn of agriculture was caused by changes in diet, but others have countered that it may be that pre-agricultural hunter-gatherers did not suffer from the diseases of affluence because they did not live long enough to develop them. Based on the data from hunter-gatherer populations still in existence, it is estimated that at age 15, life expectancy was an additional 39 years, for a total expected age of 54 years. At age 45, it is estimated that average life expectancy was an additional 19 years, for a total expected age of 64 years. That is to say, in such societies, most deaths occurred in childhood or young adulthood; thus, the population of elderly – and the prevalence of diseases of affluence – was much reduced. Excessive food energy intake relative to energy expended, rather than the consumption of specific foods, is more likely to underlie the diseases of affluence. "The health concerns of the industrial world, where calorie-packed foods are readily available, stem not from deviations from a specific diet but from an imbalance between the energy humans consume and the energy humans spend."
Primal Body-Primal Mind: Beyond the Paleo Diet for Total Health and a Longer Life by Nora Gedgaudas advocates a diet that our paleo ancestors ate. Meat, lots of fat, and seasonal fruits and berries when available. Basically, sugar and starchy carbs are discouraged. You can download a chapter from the author's site. She has a Primal Body, Primal Mind Radio weekly show on Voice of America. It started May 20, 2009, so there are many shows you can listen to. Published June 30, 2011.
Rice is a grain, and grains are a paleo no-no for sure. Our family has recently re-introduced small amounts of white rice and even smaller amounts of red potatoes. We don't eat it often, and when we do, we don't eat large portions. For the most part, we are an active family (especially Rob and I, what with CrossFit and all) and replenish every now and then with a little extra starch. We don't have any medical conditions that can be aggravated by eating these starches, so it's a personal choice that we have made. White rice is making a comeback in most paleo circles, but this is a personal choice for you. Don't do it just because it's in this recipe if eating white rice doesn't agree with you.
I LOVE Whole30. I preach it and I live it. The reason I am only posting 3 stars is because I am really disappointed in this cookbook, which I anticipated for months. I love crockpot meals and soups, and this didn't hardly have anything like that. Most of these meals did not look very appetizing. I don't want to have to purchase odd ingredients for that 1 meal and you'll be doing that with every one of these recipes. I hope they come out with another cookbook that focuses more on altering the more common meals that we are comfortable with.

CrossFit is promoted as both a physical exercise philosophy and a competitive fitness sport, incorporating elements from high-intensity interval training, Olympic weightlifting, plyometrics, powerlifting, gymnastics, girevoy sport, calisthenics, strongman, and other exercises. It is practiced by members of over 13,000 affiliated gyms, roughly half of which are located in the United States, and by individuals who complete daily workouts (otherwise known as "WODs" or "workouts of the day"). CrossFit has been criticized for allegedly causing people to suffer from unnecessary injuries and exertional rhabdomyolysis.
