Paleonutrition by Mark Q. Sutton, Kristin D. Sobolik, and Jill K. Gardner is the analysis of prehistoric human diets and the interpretation of dietary intake in relation to health and nutrition. This is a substantial text that combines background to paleonutrition, an extensive bibliography, a discussion on methods, and case studies. Published February 23, 2010.
As of 2016 there are limited data on the metabolic effects on humans eating a paleo diet, but the data are based on clinical trials that have been too small to have a statistical significance sufficient to allow the drawing of generalizations.[not in citation given] These preliminary trials have found that participants eating a paleo nutrition pattern had better measures of cardiovascular and metabolic health than people eating a standard diet, though the evidence is not strong enough to recommend the paleo diet for treatment of metabolic syndrome. As of 2014 there was no evidence the paleo diet is effective in treating inflammatory bowel disease.
That being said, I wasn't surprised to see Whole30 on the naughty list last year. In case you're not familiar with the program, you cut out all processed foods, grains, legumes, soy and dairy (that includes sugar and alcohol) for 30 days. You're left with meats, seafood, fruits, vegetables, nut butters and nut milks (as long as there's no added sugar — read your labels).
