The studies included represent an expansion of the concepts
introduced in the three papers below.

Categories where evidence is stronger include MetS, T2DM, CVD risk parameters and Epilepsy (see recent review by Sukkar et al). Other areas are emerging evidence and the articles available to date reflect this. Some of the studies use diets that are therapeutic in effect with features of carbohydrate restriction such as gluten free or emphasise unprocessed foods etc – this is particularly in areas where the evidence is emergent.
