(HealthDayNews) -- In case you thought you had a complete list of all the foods you're supposed to eat to help keep you healthy, add another item: walnuts.
According to the journal Preventive Medicine, French researchers
studied blood cholesterol levels in the country's walnut-growing regions and found that the greater the walnut consumption, the lower the cholesterol.
Beware, however: researchers haven't yet determined exactly how many walnuts you need to eat before there's a measurable difference in your cholesterol levels.
