Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health by Gary Taubes expounds on his 2002 article in the NY Times (What if It's All Been a Big Fat Lie?) and then in Science Magazine (see below). He shows how public health data has been misinterpreted to mark dietary fat and cholesterol as the primary causes of coronary heart disease. Deeper examination, he says, shows that heart disease and other diseases of civilization appear to result from increased consumption of refined carbohydrates: sugar, white flour and white rice. Or in other words, without using the word Paleolithic, he justifies the paleo diet. Here is an excellent chapter by chapter summary of the book [archive.org].
Fat and Cholesterol are Good for You by Uffe Ravnskov is a new book which includes updated and simplified sections from his previous one (The Cholesterol Myths). Ravnskov also presents his own idea about the cause of heart disease, an idea that explains all the findings that do not fit with the present view. It is a powerful book. Also see his web site. The Amazon.com reviews average to 5 stars. Published January 26, 2009.
Additionally, the Paleo diet puts a heavy emphasis on meat products. For this reason, the Paleo diet may not be suitable for everyone, and you’re unlikely to find a Paleo diet vegetarian or vegan modification out there.

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.

The diet ranked last among 38 popular diets evaluated by U.S. News & World Report in its 2016 Best Diets Rankings; one of the raters, dietitian Meridan Zerner said: "We want behavioral changes and dietary changes that are slow and progressive and meaningful." David L. Katz said of the diet: "The grouping [of banned foods] is both random, and rather bizarre from a nutrition perspective. If the idea is good nutrition, cutting out whole grains and legumes is at odds with a boatload of evidence." It was selected as one of the worst health trends for 2013 by Health Magazine.
