The Dietary Guidelines for Americans 2005, issued in January, suggests some key dietary changes for consumers. For starters, the guidelines encourage every American more than eight years of age to consume three servings of low-fat or fat-free dairy products each day. In addition, they also tell Americans to consume a sufficient amount of fruits and vegetables while staying within their energy needs. For a reference 2,000-calorie-a-day diet, two cups of fruit per day are recommended.
