High-Protein Diets
AHA Recommendation
The American Heart Association doesn't recommend high-protein diets for
weight loss. Some of these diets restrict healthful foods that provide
essential nutrients and don't provide the variety of foods needed to
adequately meet nutritional needs. People who stay on these diets very
long may not get enough vitamins and minerals and face other potential
health risks.
Many Americans follow popular diets, such as the Atkins, Zone, Protein
Power, Sugar Busters and Stillman diets. Most of these diets aren't
balanced in terms of the essential nutrients our bodies need. Some are
high protein and emphasize foods like meat, eggs and cheese, which are
rich in protein and saturated fat. Some restrict important
carbohydrates
such as cereals, grains, fruits, vegetables and low-fat dairy products.
If
followed for a long time, they can result in potential health problems.
That's why the American Heart Association guidelines urge adults who are
trying to lose weight and keep it off to eat no more than 30 percent of
total daily calories from fat and less than 10 percent from saturated
fat.
On most high-protein diets, meeting these goals isn't possible.
Some high-protein diets de-emphasize high-carbohydrate, high-fiber
plant foods. These foods help lower cholesterol when eaten as part of a
nutritionally balanced diet. Reducing consumption of these foods
usually means other, higher-fat foods are eaten instead. This raises
cholesterol levels even more and increases cardiovascular risk
Most Americans already eat more protein than their bodies need. And
eating too much protein can increase health risks.
UWAGA UWAGA:
High-protein animal foods are usually also high in saturated fat. Eating
