THE CASE AGAINST TRANS FAT
A 1997 study led by HSPH Associate Professor of Nutrition and Epidemiology Frank Hu found that for each 5 percent increase in energy intake from saturated fat, the risk of coronary heart disease (CHD) increased by 17 percent. For each 2 percent increase in energy intake from trans fat, the risk rose by 93 percent.The good news? Vegetable-derived fats had an inverse relationship to CHD. For every 5 percent rise in energy intake from monounsaturated fats, CHD risk fell by 19 percent. For every 5 percent rise in energy intake from polyunsaturated fats, the reduction in CHD risk was even more impressive: 38 percent.
