A diet
that includes three daily servings of whole
grains appears to help people live longer,
including by reducing the rates of death from
heart disease and cancer, according to findings
released Monday.
For each 16-gram serving of whole grains,
public health researchers at Harvard University
noted a seven percent decrease in overall risk
of death, including a nine percent decline in
risk of heart disease death and five percent
decline in risk of cancer-related death.
Upping whole grain intake to three servings per
day, or 48 grams, brought about a 20 percent
drop in overall risk of death, including a 25
percent decline in risk of heart disease death
and 14 percent decline in risk of cancer-related
death.
For their research, scientists analyzed results of
more than 12 previous studies conducted
between 1970 and 2010 in the United States,
Britain and Scandinavian countries, involving
786,076 male and female participants.
“These findings further support current dietary
guidelines that recommend at least three daily
servings (or 48 grams) of whole grains to
improve long-term health and prevent premature
death,” senior author Qi Sun of Harvard’s
Department of Nutrition said in a statement.
He warned against popular low-carbohydrate
diets that ignore the benefits of whole grains,
saying they should be “adopted with caution”
because they may be linked to higher risk of
heart disease and death.
Whole grains include foods such as whole
wheat, oats, brown rice and quinoa. They
contain fiber, which may improve cholesterol
levels and lower the risk of heart disease,
stroke, obesity and type two diabetes.
Whole grains also provide nutrients like B
vitamins and minerals that are lost during the
refining process.
The American Heart Association recommends a
diet rich in fruit and vegetables, and says least
half of grain consumption should be whole
grains.
Among the participants in the combined studies,
there was a total of 97,867 deaths, including
23,597 deaths from cardiovascular disease and
37,492 deaths from cancer.
The study was published online in Circulation,
the journal of the American Heart Association.
