Low-Carb Diet Can Be Heart-Healthy

Low-Carb Diet Can Be Heart-Healthy

WEDNESDAY, Nov. 8 (HealthDay News) — A low-carbohydrate diet does not increase the risk of heart disease in women, a major new study finds.

However, while the regimen skimped on bread and other carbohydrate foods, it was not the fatty Atkins diet that most people associate with the term "low-carb diet."

In a 20-year study involving over 82,000 women, the incidence of coronary heart disease was roughly equal for women who ate low- and high-carbohydrate diets, researchers reported in the Nov. 9 New England Journal of Medicine.

Heart risk was also 30 percent lower for
participants who got their protein and fat from vegetables rather than
from meat, they noted.

The Atkins diet, which became popular after its introduction in the 1970s, allows for unlimited intake of animal fat.

"I
feel the take-home message of the investigation is that neither the
low-fat or low-carbohydrate dietary pattern is ideal," said researcher
Thomas L. Halton, who led the study while a doctoral student at the
Harvard School of Public Health. "Both have strengths and weaknesses.
However, you can get the best features of both diets and eliminate the
negative features of both diets by choosing healthy vegetable sources
of fat and protein."

The real goal is "taking steps to reduce the glycemic load of the diet
by substituting lower glycemic fruits, vegetables and whole grains as
well as vegetable sources of fat and protein for refined, high-glycemic
carbohydrates," said Halton, who now teaches part-time at Simmons
College in Boston

In the study, researchers tracked the health
of more than 82,802 women in the Nurses Health study followed for 20
years, looking especially at the incidence of coronary heart disease.
The women filled out questionnaires on their eating habits, and this
information was used to calculate their percentage of energy intake
from carbohydrate, fat and protein.

"The main message I walked away with is that a diet
rich in vegetable protein and vegetable fat appears to have a benefit
in lowering heart disease risk," said Susan Moores, a nutritional
consultant in St. Paul, Minn., and a spokeswoman for the American
Dietetic Association.

The women in the study reported "not what people think of as a low-carbohydrate diet, more of a moderate-carbohydrate diet,"
Moores said. "When you look at the amount of carbohydrates in the diets
of women reporting the lowest levels, they were not eating a
low-carbohydrate diet like the Atkins diet."

It’s
difficult to make specific recommendations based on the study because
"there are so many qualifiers and questions about the diets the women
actually ate," she said. "And it is hard to draw the conclusion that an
Atkins-type diet affects the risk of heart disease."

But
it was satisfying to see the benefits of eating plant-based fats and
proteins laid out in the report, Moores said. "We have talked about it
for years, and it is so nice to see it validated for a large group of
women,"
