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 middleaged 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
The test subjects in the recent study who ate fish twice a week were not significantly more likely than those who did not to engage regularly in activities known to augment cardiorespiratory health.
