Anna,

That is good to know, but what are the negative effects of paleo? A study I read compared weight loss between a control group on an average healthy diet (15% protein, 25-30% fat, 55-60% CHOs) compared to the intervention group on a paliolithic diet (40% fat, 30% protein, and 30% CHOs). The paleolithic diet was based on lean meat, fish, eggs, vegetables, fruits, berries, and nuts. There were no significant differences in the anthros at 24 months. Triglyceride levels were significantly lower in the paleo group, but the adherence to protein was poor in that group. It seems to me that the paleo is beneficial because they are sticking to the diet not because of the diet itself.

A gluten-free diet is not beneficial for those without Celiac Disease or Gluten sensitivity. When a person cuts out significant food groups from their diet, they run the risk of cutting out important nutrients and becoming deficient in those nutrients. A gluten-free diet is low in nutrients such as: B vitamins, calcium, iron, zinc, magnesium, and fiber (1). A study conducted on children consuming a gluten-free diet showed a lower intake in dietary fiber, vitamin D, magnesium, and selenium compared to children on a normal diet (2). There is no point in cutting out gluten and eliminating these nutrients because they are hard to replace through other parts of the diet (1). There also is the fact that gluten-free foods are more expensive and harder to find. Gluten-free versions of wheat based foods were found to be 518% more expensive than the standard wheat products (3). A gluten free diet may be beneficial for someone experiencing symptoms of Celiac disease but if you really want to know if you have a gluten intolerance, go get tested (1).
