Many cultures have been happily eating unrefined soy beans, tofu and tempeh for millennia. Those forms of soy are not the problem. it's the processed food soybean oil.

Saturated animal fats have their own specific problems. The science is clear on that. It's not just soy oil, it's not just animal fat, it's not just sugar, it's not just refined flours. It's all of them.

Michael Pollan's advice is still best: "Eat food. Not too much. Mostly plants."
