Know this: Eating healthfully can save you money.
With a little planning, eating well can actually cost less than typical fast-food fare. Are you surprised? A study at the Mary Imogene Bassett Research Institute in Cooperstown, N.Y., found that a person who follows a heart-healthy diet can reduce her grocery bill by up to $8 a week. That translates to an annual savings of $416 a year for a single person or $1,664 for a family of four. Granted, wild salmon and imported olive oil cost more than a Happy Meal, but you need to factor in the hidden costs of a diet that is high in fat.

More than half of all Americans eat too much, with the extra pounds costing about $400 per person in added health-care bills, not to mention the more than $30 billion spent annually in this country on weight-loss products and services.

Pound for pound, health-boosting whole foods are a lot cheaper than fast-food fare. To help pare down your grocery bill, swap legumes for meat products; buy less-expensive produce such as apples, oranges, carrots, spinach and cabbage; and purchase whole grains like oatmeal, rice and bulgur in bulk.
