Southern, fried foods raise stroke risk, new study shows
Eating lots of fried foods and
Southern-style cuisine may significantly raise a person's risk for
having a stroke, according to a new study.
Southern-style foods
consist of fried foods like fish and chicken and potatoes, bacon, organ
meats including liver and gizzards, lots of salt and sugary drinks like
sweet tea. Previous research shows Southerners are about 20 percent more
likely to have a stroke than the rest of Americans. The so-called
"Stroke Belt" of the U.S. consists of Alabama, Arkansas, Georgia,
Indiana, Kentucky, Louisiana, Mississippi, North Carolina, South
Carolina, Tennessee, and Virginia, according to the National Heart, Lung, and Blood Institute. Ten of these states are in the Southeast.
In what researchers are calling the first large-scale study on
the relationship between stroke risk and Southern foods, epidemiologists
compared the dietary habits of more than 20,000 black and white adults.
Beginning in 2003, questionnaires were given to participants from 48
states who were minimum age of 45. Each person was also given an
in-person physical exam and were followed-up with every six months to
see if they had a stroke.
Researchers found a direct relationship between the amount of Southern foods participants ate and stroke risk.
For
example, a person who ate Southern foods about six times a week were 41
percent more likely to have a stroke compared with people who ate the
cuisine once a month.
"We've got three major factors working together in the Southern-style
diet to raise risks of cardiovascular disease: fatty foods are high in
cholesterol, sugary drinks are linked to diabetes and salty foods lead
to high blood pressure," study author Dr. Suzanne Judd, a nutritional
epidemiologist at the University of Alabama Birmingham's biostatistics
department, said in a statement.
On
the flip side, participants who ate fruits, vegetables, legumes and
whole grains about five times per week were about 29 percent less likely
to have a stroke compared to those who ate them infrequently, less than
three times per week.
Eating
Southern foods was also tied to a 63 percent higher stroke risk among
black participants compared to their white counterparts. That's a red
flag, according to Judd, because the research found black participants
were five times more likely to eat Southern foods than white
participants. On top of that, black people's risk for a first time
stroke doubles that of whites, according to American Stroke Association
statistics.
While two-thirds of participants who reported eating
Southern foods lived in the Southeast, Judd emphasized that stroke risk
remains high if a person eats this diet, regardless of where they live.
The study was presented Feb. 7 at the International Stroke Conference in Honolulu.
More than 750,000 Americans suffer a stroke each year, about 610,000
of whom have one for the first time. Symptoms include sudden numbness or
weakness in the face and limbs, confusion, trouble seeing, dizziness
and loss of coordination and sudden, severe headaches. Other risk
factors include smoking, alcohol use, physical inactivity, heredity and
medical conditions like diabetes, obesity, and high blood pressure and
cholesterol.
Almost 130,000 Americans die from a stroke each year.
The American Stroke Association's Power to End Stroke campaign has more information on reducing risk.
