The research indicates African Americans may be more likely to have deficiencies in calcium (a nutrient important for healthy bones and teeth) as well as several essential vitamins and minerals that often accompany calcium in dairy products, such as phosphorus and magnesium.

Numerous previous studies have shown that low rates of calcium intake are highly correlated with low bone mass and bone fracture rates and increased risk of osteoporosis. Calcium is also necessary to help baby teeth and adult teeth develop fully. After teeth have developed, calcium may help protect them from decay. Since the body does not make calcium, daily consumption of the mineral is important for healthy bones and teeth.

The newest study analyzed data collected during two nationwide health surveys: The Continuing Survey of Food Intakes by Individuals for 1994-1996 and 1998 and the National Health and Nutrition Examination Survey for 1999-2000. Non-African Americans were defined as people who were white, Asian/Pacific, American Indian, Alaskan and other races. There were more than 31,000 total participants in the two surveys.

The study found that African American adults and children on average did not meet the 2005 U.S. Dietary Guidelines for consuming three servings of low-fat or fat-free milk or milk products (cheese and yogurt) a day.

Researchers noted that many African Americans forego milk and dairy products because they have lactose or milk intolerance that causes digestive problems like gas and bloating. However, some studies have suggested the number of people affected by the condition may be overestimated.

Researchers suggested that people who avoid dairy products can take steps to minimize the digestive problems associated with lactose intolerance by eating dairy products as part of a complete meal rather than separately and to consume small quantities of dairy throughout the day. Other tips include eating natural cheeses and live-culture yogurt or lactose-free dairy products. Nutritionists recommend other sources of calcium, including broccoli, collard greens and kale and bony fish such as salmon.

The study, published in the February issue of the Journal American Dietetic Association, was supported by the National Dairy Council.
