The original China Study, the Cornell-China-Oxford Project, which is today being widely used to promote veganism, included egg whites and dairy as part of its dietary recommendations:
The Vegetarian Diet Pyramid emphasizes a wide base of foods to be eaten at every meal, including fruits and vegetables, whole grains (oats, wheat, whole grain bread, barley, couscous, noodles, pasta, corn) and legumes (soy, beans, peanuts and other legumes). The middle band to be eaten from daily includes nuts and seeds, egg whites, dairy and soy cheese, milk (almond, dairy, rice and soy) and plant oils. The top tip of the pyramid are optional foods or foods to be eaten occasionally or in small quantities and includes eggs and sweets…
The Vegetarian Diet Pyramid was developed by nutrition scientists and medical specialists from the Cornell-China-Oxford Project on Nutrition, Health and Environment, which is based at Cornell; the Harvard School of Public Health; and the Oldways Preservation & Exchange Trust, a non-profit food-issues educational organization in Cambridge, Mass., whose mission is to preserve traditions and foster cultural exchanges in the fields of food, cooking and agriculture.
“This pyramid reflects the growing body of research that suggests that Americans will not reduce their rate of cancers, cardiovascular disease and other chronic, degenerative diseases until they shift their diets away from animal-based foods to plant-based foods,” said T. Colin Campbell, Cornell professor of nutritional biochemistry, one of the scientists who helped develop and present the pyramid at the conference and the director of the Cornell-China-Oxford Project, a massive survey of more than 10,000 families in mainland China and Taiwan designed to study diet, lifestyle and disease across the far reaches of China.
T. Colin Campbell wrote the book entitled The China Study, based on the Cornell-China-Oxford Project’s findings:
More recently, Dr. Campbell has disavowed the consumption of all eggs and dairy products.
