In short, it is about the multiple health benefits of consuming plant-based foods, and the largely unappreciated health dangers of consuming animal-based foods, including all types of meat, dairy and eggs.

First, nutrition is the master key to human health. Second, what most of us think of as proper nutrition--isn't.

Nutrition is not a mathematical equation in which two plus two is four. The food we put in our mouths doesn't control our nutrition-not entirely. What our bodies do with that food does.

The ideal human diet looks like this: Consume plant-based foods in forms as close to their natural state as possible (“whole” foods). Eat a variety of vegetables, fruits, raw nuts and seeds, beans and legumes, and whole grains. Avoid heavily processed foods and animal products. Stay away from added salt, oil, and sugar. Aim to get 80 percent of your calories from carbohydrates, 10 percent from fat, and 10 percent from protein.

There’s only one thing that we have to do in life, and that is to die.

Perhaps it is a testament to the power of modern marketing savvy that an obese man with heart disease and high blood pressure became one of the richest snake oil salesmen ever to live, selling a diet that promises to help you lose weight, to keep your heart healthy and to normalize your blood pressure.

Quite simply, the more you substitute plant foods for animal foods, the healthier you are likely to be.
