Clive Maine, McCay (1898—1967) was an American biochemist, nutritionist, gerontologist, and professor of animal husbandry at Cornell University from 1927-1963. His main interest was the influence of nutrition on aging. He is best known for his work in proving that caloric restriction increases the life span of rats, which is seen as seminal in triggering further research and experiments in the field of nutrition and longevity. Scientists are still trying to understand the connection between caloric restriction and longevity.

Following his discovery between a low calorie diet and longevity, McCay played a prominent role in the development of nutritionally-sound rations during World War II, and the creation of Cornell Bread, a type of high protein, high vitamin bread meant to echo the same high protein vitamin meal he fed to his mice in longevity experiments. His further research centered on canine nutrition, fluoride and its use in water treatment, and parabiosis. A 1957 study on fluoridation showed that low levels (1-10 ppm) of sodium fluoride added to the drinking water of rats did not have carie-protective effects.
