But not always accurate. His push of olive oil, the MED
diet and the GI have all been shown to be flawed, even by some of his own studies.
However, while the evidence pointing to this exact
diet is limited to the studies done on this exact
diet, the overwhelming body of evidence from the WHO, FAO, IOM, NAS, NIH, AICR, etc etc, points to this.

"Populations should consume nutritionally adequate and varied diets, based primarily on foods of plant origin with small amounts of added flesh foods. Households should select predominantly plant-based diets rich in a variety of vegetables and fruits, pulses or legumes, and minimally processed starchy staple foods. The evidence that such diets will prevent or delay a significant proportion of non-communicable chronic diseases is consistent. A predominantly plant-based diet has a low energy density, which may protect against obesity." "Although two-thirds of the world’s population depends on cereal or tuber-based diets, the other one-third consumes significant amounts of animal food products. The latter group places an undue demand on land, water, and other resources required for intensive food production, which makes the typical Western diet not only undesirable from the standpoint of health but also environmentally unsustainable. If we balance energy intake with the expenditure required for basal metabolism, physical activity, growth, and repair, we will find that the dietary quality required for health is essentially the same across population groups."
