Volkoren ontbijt tegen hartzwakte.*
Uit een Amerikaanse studie blijkt dat het regelmatig eten van een volkoren granenontbijt goed is voor het hart. In de studie bestond een volkoren granenontbijt uit minimaal 25% haver of zemelen. Zij die 7x per week dit ontbijt aten hadden 28% minder kans op hartzwakte. Bij 2-6 keer per week was de kans 22% kleiner en bij 1x per week 14%.
Whole-Grain
Breakfast Cereal Associated With Reduced Heart Failure Risk
Eating
whole-grain breakfast cereals seven or more times per week was associated with a
lower risk of heart failure, according to an analysis of the observational
Physicians' Health Study. Researchers presented findings of the study at the
American Heart Association's 47th Annual Conference on Cardiovascular Disease
Epidemiology and Prevention. For the present study, breakfast cereals that
contain at least 25 percent oat or bran content were classified as whole grain
cereals.
The analysis shows that those who ate a whole-grain breakfast cereal seven or
more times per week were less likely (by 28 percent) to develop heart failure
over the course of the study than those who never ate such cereal. The risk of
heart failure decreased by 22 percent in those who ate a whole-grain breakfast
cereal from two to six times per week and by 14 percent in those who ate a
whole-grain breakfast cereal up to once per week.
According to researchers, if this data is confirmed by other studies, a healthy
diet including whole-grain breakfast cereals along with other measures may help
reduce the risk of heart failure.
"There are good and powerful arguments for eating a whole-grain cereal for
breakfast," said Luc Djoussé, M.D., M.P.H., D.Sc., lead author of the
study and assistant professor of medicine in the Division of Aging at Brigham
& Women's Hospital and Harvard Medical School in Boston, Mass. "The
significant health benefits of whole-grain cereal are not just for kids, but
also for adults. A whole-grain, high-fiber breakfast may lower blood pressure
and bad cholesterol and prevent heart attacks."
Djoussé urges the general public to consider eating a regular whole-grain,
high fiber breakfast for its overall health benefits.
In the Physicians' Health Study, the majority of the physicians in the study ate
whole-grain cereals rather than refined cereals. Whole grains are rich in
vitamins, minerals, and anti-oxidants and have a high fiber content. Of 10,469
physicians reporting cereal consumption at baseline, 8,266 (79 percent) ate
whole-grain cereals compared to 2,203 (21 percent) who ate refined cereals.
Among the physicians who ate whole-grain breakfast cereals, 2,873 (35 percent)
said they ate them seven or more times per week; 3,240 (39 percent) said two to
six times per week; and 2,153 (26 percent) said they ate up to one cereal
serving per week.
The findings reported here were based on annual detailed questionnaires about
major heart events and reported breakfast cereal consumption at baseline.
However, the results did not change when possible changes in cereal consumption
over time (assessed at 18 weeks; two years; four years; six years; eight years;
and ten years) were taken into account. Researchers conducted the study from
1982 to 2006. The average age of physicians in the study at baseline was 53.7
years. Djoussé hopes the findings of the Physicians' Health Study will
encourage the general population to eat heart-healthy diets.
"The Physicians' Health Study shows that even in a population with overall
healthy behavior, it is possible to see less heart failure in those who eat a
whole-grain cereal breakfast," Djoussé said.
In the United States, foods considered "whole grain" contain 51
percent or more whole grain ingredients by weight per reference amount
customarily consumed. ###
