High-Fiber Diet Has Its Drawbacks

High-fiber weight-loss diets which prescribe unlimited amounts of fruits, vegetables and whole grains may help shed pounds, but they are frequently low in valuable nutrients like protein, calcium and iron, says a registered dietitian with the American Heart Assn. and the Dairy Council of California.

“Protein, calcium and iron are generally found in dairy products or meat group foods--foods that are often eliminated or underemphasized in high-fiber diets,” said Judith Levine, an RD in San Francisco.

Levine pointed out that weight watchers can enjoy the benefits of fiber without sacrificing important nutrients if they incorporate fiber-rich foods into a balanced diet.

Supplying Needed Nutrients

A daily diet plan consisting of two servings of low-fat milk, yogurt or cheese; two servings of lean meat, fish, poultry or legumes; four servings of fruits and vegetables and four servings of whole grain breads and cereals will supply 1,200 to 1,400 calories. This plan includes 20 to 25 grams of fiber and all the nutrients necessary to stay healthy and active.

“Adding large amounts of pure fiber, such as bran, to foods can result in dehydration and digestive tract problems,” Levine said.

“Dieters can avoid unpleasant side effects by gradually adding fiber foods to the diet and drinking plenty of fluids.”

For breakfast, try a whole-grain waffle topped with a dollop of low-fat or nonfat yogurt, or have a bowl of bran cereal, fruit and milk.
