Unsaturated fatty acids in adipose tissue of Israeli Jews

The ratio of polyunsaturated to saturated fatty acids in the adipose tissue of Israelis was found to be 0.88 for Ashkenazic Jews and 1.13 for non-Ashkenazic Jews, the highest reported for any population on a free-choice diet. Despite the unusually high ratios, indicating a high consumption of polyunsaturated fat, there is nevertheless, a relatively high incidence of ischemic heart disease among Israelis.
