Getting Nutrition Guidance
May 8, 2000 -- The ancient pyramids have long conjured up visions of King Tut, golden statues, and the dusty sands of Egypt. Our own homegrown version of the pyramid symbolizes something a little less exalted: good nutrition. Even so, the U.S. Department of Agriculture's (USDA) Food Guide Pyramid, the nation's official advice on diet, promises the key to a long and healthy life.
But in an age of ethnic and fusion cuisines, when was the last time you saw tortillas and jalape?os on the pyramid? Or bok choy and edamame soybeans? They don't appear, of course, which is just one reason why critics have complained recently about the official guidelines. Instead of reflecting the fast-changing face of America, they charge, the pyramid remains culturally biased. Worse yet, it's out of touch with current nutrition research. Some critics say that the pyramid places too much emphasis on dairy and meat products. Others worry that it encourages people to eat more meat than is healthy.
Editor's Note: Food Pyramid Replaced
In June 2011, the USDA replaced the food pyramid with a new plate icon.
Most Minorities Can't Take Lactose
More immediate are the severe cramps, diarrhea, and gas that millions of lactose-intolerant Americans can suffer from eating the dairy products emphasized on the pyramid. Without the ability to digest the sugars in milk, people with lactose intolerance, including 90% of Asians, 70% of African-Americans and Native Americans, and 50% of Latinos, aren't likely to get enough bone-strengthening calcium. They avoid dairy products without substituting other foods that are also rich in calcium.
To remedy that situation, the Physicians' Committee for Responsible Medicine (PCRM), a pro-vegetarian advocacy group, is currently lobbying health officials to list other calcium-rich foods on the pyramid. Broccoli, collards, and other dark-green leafy vegetables are great sources of calcium, says Milton Mills, MD, an associate director of preventive medicine at PCRM.
Other good alternatives are lactose-free dairy products, available in many grocery stores, and yogurt or buttermilk. Though these last two are officially dairy foods, both contain bacteria that digest lactose.
No Limits Needed on "Good" Fats
Another disagreement centers on how much fat a healthy diet should contain. The USDA Dietary Guidelines proposed for the year 2000 recommend that no more than 30% of the day's total calories should come from fat. But people who follow the traditional heart-healthy Mediterranean diet typically consume as much as 45% of their daily calories as mono- and polyunsaturated fats.
In the days of lard and tropical oils, it made sense to cut back on total fat. But if you use unsaturated oils like canola and safflower oils, says Meir Stampfer, MD, professor of epidemiology and nutrition at the Harvard School of Public Health, there's no need to fret about how much you consume.
"I wanted them to get rid of the restriction on 'total fat' entirely," Stampfer says. It is true that saturated fats are directly linked to elevated cholesterol levels. He goes on to explain that mono- and polyunsaturated fats, like those found in olive and canola oils, have been shown to prevent blood cholesterol levels from climbing.
