Aging is the result of biological changes that occur in multiple organ systems. The rate of aging is determined by a combination of genetic and environmental factors. Chronic disease contributes to the aging process by hastening the rate and accumulation of damaging cellular alterations. Coronary heart disease (CHD) is a multi-factorial chronic disease that begins in childhood and progresses with age. CHD remains the leading cause of death and disability globally, with approximately 3.4 million deaths in women and 3.8 million deaths in men each year. It is estimated that 60% of these deaths occur within low- and middle-income countries. Many factors, particularly diet and lifestyle practices, can slow the progression of age-related diseases. The study of dietary patterns is increasingly used in investigations of longevity to define those that are useful for predicting mortality and longevity. It has been postulated that a dietary pattern followed over a lifetime contributes importantly to the development of age-related diseases. The purpose of this paper is to describe major dietary patterns that are associated with increased longevity and lower rates of age-related diseases such as CHD.
