The evidence has been converging for decades.

The nutrition literature is noisy because food is emotional and industry-funded. Cut through it and the consensus is boring: eat more legumes, whole grains, nuts, fruit and vegetables. Eat less red and processed meat. That advice comes from every major health authority — the WHO, the American Heart Association, the Academy of Nutrition and Dietetics.

A well-planned plant-based diet is nutritionally adequate for every life stage. B12 supplementation is required (it's a bacterial vitamin, not an animal one). Iodine, omega-3s and vitamin D warrant attention. Everything else is easier than most people think.
