The Nutrition Committee of the American Heart Association recently published its new recommendations for the prevention of cardiovascular disease.

One major change from past recommendations is an emphasis on general lifestyle recommendations rather than a strong, almost exclusive focus on diet.

Most of the dietary recommendations remain unchanged, such as these:

• Limit salt intake.
• Eat plenty of vegetables and whole fruits, rather than juices.
• Choose foods made with whole grains.
• Use lean cuts of meat and remove skin from poultry before baking.
• Select milk and dairy products that are either fat-free or low-fat.

Here are some of the dietary changes and new emphases:

• Limit saturated fat to less than 7 percent of calories and trans fats to less than 1 percent of calories.
• Minimize the consumption of beverages containing added sugars.
• Eat fresh, frozen, and canned vegetables without high-calorie sauces or added salt and sugar.
• The cardiovascular effects of antioxidant supplements, soy protein, folate and other B vitamins, and phytochemicals are unproven or uncertain.
• Exercise at least 30 minutes every day. Urge all family members to spend less time watching television, surfing the Web, and playing computer games.

A spokesperson for the AHA committee that devised the guidelines emphasized that a key message is "to focus on long-term, permanent changes in how we eat and live."

I strongly support this statement because too many of my patients have adopted dietary changes and improved their exercise habits - and followed them for about as long as most people adhere to their New Year's resolutions.
