“Our study [China Diet and Health Study] suggests that the closer one approaches a total plant food diet, the greater the health benefit. … It turns out that animal protein, when consumed, exhibits a variety of undesirable health effects. Whether it is the immune system, various enzyme systems, the uptake of carcinogens into the cells, or hormonal activities, animal protein generally only causes mischief. High fat intake still can be a problem, and we ought not to be consuming such high-fat diets. But I suggest that animal protein is more problematic in this whole diet/disease relationship than is total fat.”

“We used to recommend meat, poultry, and fish for children because they are rich in protein and iron. However, we now know that there are harmful effects of a meaty diet, particularly changes in the arteries and weight problems, and that these changes begin in childhood. When children develop a taste for meats, it is hard to break this habit later on. It turns out that children can get plenty of protein and iron from vegetables, beans, and other plant foods that avoid the fat and cholesterol that are in animal products.”

“Diabetes is not and never was caused by eating a high carbohydrate diet, and it is not caused by eating sugar. The cause of diabetes is a diet that builds up the amount of fat into the blood. I'm talking about a typical meat-based, animal-based diet. You can look into the muscle cells of the human body, and you find they're building up tiny particles of fat which is causing insulin resistance. What that means is the sugar that is naturally from the foods that you're eating can't get into the cells where it belongs. It builds up in the blood and that is diabetes.”

“When the ratio of nutrients to calories is high, fat melts away, and health is restored. The more nutrient-dense food you consume, the more you'll be satisfied with fewer calories, and the less you'll crave fat and high-calorie foods.”

“I still believe that a plant-based diet has tremendous health benefits but I have incorporated more animal protein into my diet. I found that my body personally got to a point where I needed something more. I used to yell at people who said that, but now all of a sudden, my body just kind of went, ‘I need something.”

“For those who are still merely vegetarian and not yet vegan, I ask, what in heaven's name are you waiting for? If you are trying to avoid the health pitfalls of eating carcasses—high fat, saturated fat, and cholesterol content; lack of fiber; deficiency of vitamins and enzymes; abundance of stored toxins—well, then take a good look at the dairy you're eating. Dairy is basically liquid meat without the iron. … Milk should be viewed as no more or less than what it is: a delivery system for fat, cholesterol, blood, pus, antibiotics, and carcinogenic growth hormones. … If your reason for abstaining from meat has more to do with an emotional attachment to animals than a concern for your health, then understand that dairy cows are truly sick, miserable, abused creatures … Someone who has become vegetarian for emotional reasons ought to switch to the vegan diet as swiftly and surely as someone brought to vegetarianism for reasons of health.”

“Populations with diets with little or no saturated fat have little or no heart disease. The development of heart disease begins in childhood. Not only do unhealthy childhood diets high in saturated fat and low in the protective micronutrients found in unprocessed plant foods accelerate heart disease, but they promote the aging process, and create a cellular environment favorable for the development of cancer. To add insult to injury, much of the processed foods children eat are rich in trans fat, a man-made fat that is also linked to cancer and heart disease. We could not have designed a cancer-causing environment more effectively if we scientifically planned it. We feed our children a diet high in saturated fat, add lots of processed foods with those dangerous (man-made) trans fats, and combine it with an insufficient intake of unrefined plant foods to guarantee sufficient phytochemical deprivation, and presto, we have created a nation rich in autoimmune illnesses, allergies, obesity, diabetes, and finally, heart disease and cancer.”

“Fruit and vegetables, instead, are foods extremely low in fats and high in fiber: by easing the passage of ingested food, they reduce the time of contact between possible carcinogens—present in our daily diet—with the walls of the intestines.”

“Whether you eat a vegetarian diet or you include a very small amount of animal foods, for optimal health you must get the majority of calories from unrefined plant food with a minimal amount of animal products. A large quantity of unrefined plant food grants the greatest protection against developing serious disease.”

“If I could deliver one message to the researchers who are looking for the cause of diabetes, and the cause of clogged arteries, and the cause of high blood pressure, and the cause of obesity, I would tell them the answer is in three words. It's the food! … If people adopted a plant-based diet, the changes we would see in our individual health, in our national health situation and in this physical, environmental world we live in, would be so profound.”
