I would say that diets containing, well, theoretically, 8-9% fat is enough ... Of course, we go higher that, as we know. We're far, far higher. And a lot of it comes from animal foods, but actually the majority of that now, as you know well, is coming from added oils.

Health doesn't come from the end of a needle or from a pill; it comes from the food we put in our mouth.

The low-carb diet, the better name for that, it should be called a high-protein, high-fat diet. And there is no evidence, I find no evidence in the scientific literature or any place else, that you can actually take that kind of diet and treat and reverse disease.

Nature had it that we should keep a balance of omega-6 to omega-3; it should be around 2 to 1, 3 to 1, maybe 4 to 1, something like that ... But in fact, we're like 20 times that. So, we're consuming, really, a very pro-inflammatory diet, largely comprised of added oils.

We don't have a good immune system for the same reason that we have a lot of heart disease, for the same reason we have a lot of diabetes, the same reason we have a lot of obesity and cancer—because nutrition.

Consuming a more plant-based diet actually builds the immune system almost better than anything. And that immune system is what handles pathogens like bacteria or fungi or viruses, if you will, or new cancer cells.

The environment, the environment problems we have, global warming and climate change... The number one cause of that problem... is we're eating the wrong food, producing the wrong food, that just tears up the environment.

For type 2 diabetics who are taking insulin, just to give another example, if they switch to this whole food plant-based diet, the changes kick in so fast that, were they not to be careful, and they're still taking their drugs, they can go into hypoglycemic shock. In other words, the blood sugar really drops like a rock.

As far as the protein itself is concerned, surely those kinds of proteins, the plant-based proteins, they're going to be better. There's no question about that.

One thing is important to say, though: We do not need to eat animals in order to get the protein. That's very clear.

Doctors don't get trained in nutrition. There's not a medical school in the United States where they teach nutrition ... They're trained to treat illness, primarily through the use of pharmaceuticals or drugs. So, nutrition is kind of strange to them.

It's abundantly clear to me, even more now than ever, that when we eat food, we're eating countless nutrients and nutrient-like substances ... They're not operating independently ... They work together in an integrated fashion for the most part.

We can get all the protein we need from whole plants.

The average rural Chinese person is eating about 15% of their calories from fat, and Americans are at like 37%.

There are virtually no nutrients in animal-based foods that are not better provided by plants.
