>we have seen that patients who ate mostly plant-based meals, with dishes like black bean vegetarian chili and whole wheat penne pasta with roasted vegetables, achieved reversal of even severe coronary artery disease. They also engaged in moderate exercise and stress-management techniques

Ask any of the 1% or so of the population medically diagnosed with celiac disease. If wheat was "invented" today instead of being a popular historical ethnic food, there's no way the USDA / FDA would allow it to start being sold knowing it makes so many people very ill.
Wheat isn't dangerous, it's just not very good for you.
