In addition to these theories of heart disease, the American Heart Association has espoused the theory since the 1960s that the major cause of heart disease in Western nations (atherosclerosis) is dietary, "the lipid hypothesis, namely that dietary saturated fat and cholesterol lead to elevated levels of cholesterol in the blood, and that these elevated levels of cholesterol cause the pathogenic atheromas that block blood vessels" (Fallon et al. 15). Other authors like Mary P. McGowan in her book, Heart Fitness for Life, agree with the theory that diet has a profound impact on the formation of or prevention of heart disease.
