Fiber consumption has long been known to reduce cholesterol levels in a dose-dependent fashion.

Current recommendations are to get 15+ grams of fiber per 1000 Calories, but we know from, e.g., hunter-gatherer populations that humans can eat far more than that.

Building a diet around whole food sources that are high in fiber and protein is basically all you need for a healthy diet, constrained by however many calories you need to support a healthy weight.

Fruits, veggies, legumes, whole grains, nuts, seeds, etc. should make up the majority of your diet.
