PrepTest 50, Section 3, Question 11
Scientists have long thought that omega-3 fatty acids in fish oil tend to lower blood cholesterol and strongly suspected that a diet that includes a modest amount of fish would provide substantial health benefits. Now these views have acquired strong support from a recent study showing that middle-aged people who eat fish twice a week are nearly 30 percent less likely to develop heart disease than are those who do not eat fish.
