Quotations by T. Colin Campbell

In my own research program in the 1970s and 1980s on experimental rats, as well as in The China Study, we repeatedly established the ability of higher consumption of the milk-based protein casein to dramatically increase a growth hormone associated with increased cancer development. In contrast, high levels of a "low-quality" wheat protein had the opposite effect. Due to its "deficiency" in the amino acid lysine, the wheat protein prevented cancer development. (We know that the missing lysine was responsible for this change because when lysine was restored, cancer growth resumed to the same level as for the casein.) [2020] - T. Colin Campbell

At its simplest and most accessible, the whole food, plant-based (WFPB) diet can be described in a dozen words, distilled into two recommendations: 1. Consume a variety of whole plant-based foods. 2. Avoid consumption of animal-based foods. [2020] - T. Colin Campbell

Experimental laboratory-animal studies observed a strong and mostly causal association between modestly high consumption of animal protein (anything in excess of about 10% of calories) and cancer--an effect that was not observed in the consumption of plant protein. Increasing dietary protein intake to just 20% has been shown to increase a range of serious health problems, including cancer, with each successive percentage increase associated with an increase in response, commonly referred to as a dose-response. There are virtually no nutrients contained in animal foods that are not better provided by plant foods. [2020] - T. Colin Campbell

Polyunsaturated fats in the context of whole foods behave differently than when they're extracted from plants and put into a bottle. Whole foods contain many antioxidative factors (antioxidants, minerals), and thus able to control the damage of free radical production that otherwise might occur when these oils are consumed in isolation, such as added oils. Whereas the consumption of isolated oils should be avoided to minimize risk of heart disease, cancer, obesity, and related chronic diseases, whole plant foods containing these fats (nuts, seeds, avocados, etc.) are generally nutritious when consumed in moderation. [2020] - T.

A diet low in cholesterol but high in animal protein would increase blood cholesterol more than a diet low in animal protein. Whereas cholesterol and saturated fat can easily be removed from animal foods, as in the case of skim milk and lean cuts of meat, the removal of protein would result in a far less appetizing dinner party. [2020] - T.
