How to eat heartily.

How to eat heartily

The American Heart Association (AHA) has just issued minor changes to its dietary guidelines aimed at preventing heart disease. In the March issue of CIRCULATION, the group recommends: limiting dietary fat to less than 30 percent of calories, with polyunsaturated and saturated fats each accounting for no more than 10 percent of total calories; limiting dietary cholesterol to 300 milligrams per day; making carbohydrates 50 percent or more of one's calories allowance, with emphasis on complex carbohydrates; letting protein provide the remainder of calories. In addition, AHA recommends limiting sodium to 3 grams daily and alcohol consumption to 1 or 2 ounces of ethanol daily.

The major difference between this list and the one issued in 1986 (SN: 8/30/86, p.135) is that the earlier one tied quantitative limits -- such as 300 mg of cholesterol -- to each 1,000 calories consumed. The new version makes such limits a rigid daily total, even for people consuming more than 2,000 calories.
