Until recently the conventional wisdom among health-
conscious Americans was to avoid nuts because of their
extremely high fat content. But within the past several years,
nutritionists and health researchers have taken another look
at nuts. The Harvard Heart Letter reported that much of the
momentum for giving nuts a second chance comes from a
long-term study of diet and heart disease in more than
26,000 Seventh Day Adventists in California that began in the
mid 1970s. One of the results, reported in 1992, aroused the
curiosity of health researchers — a strong association
between higher nut consumption and a lower risk of heart
disease. People who consumed tree nuts (pecans, almonds,
walnuts, etc.) frequently (at least 5 times a week) had
roughly half the risk of a heart attack or a coronary death as
those who rarely ate them. People who ate a portion of nuts
even once a week had about a 25% lower risk of heart
disease than those who avoided nuts.”
