Fried chicken on a waffle, washed down with sweet tea — it’s a classic Southern lunch. That fat/sweet nexus is also a recipe for a stroke, according to a recent study.

Researchers at the University of Alabama in Birmingham have been trying to nail down out how diet relates to stroke, particularly in the “Stroke Belt” — the Southeastern states that have the dubious distinction of hosting the nation’s highest stroke rates.

Diet has always been considered a major culprit. But this big study, with 20,239 people tracked over five years, let the researchers slice and dice eating habits much more finely. They came up with five eating styles:

– Southern: fried chicken and fish, lunch meat, gizzards and other organ meats, sweet tea and other sugar-sweetened drinks

– Convenience: Mexican and Chinese food, burgers, pizza, pasta

– Plant-based: fruits, vegetables, juice, cereal, fish, poultry, yogurt, nuts, whole-grain bread

– Sweets: added fats, bread, chocolate, dessert, sweet breakfast food

– Alcohol: beer, wine, liquor, green leafy vegetables, nuts and seeds, coffee

People who ate the Southern diet had a 41 percent higher risk of stroke, while the plant-eaters’ risk was 30 percent less. Those results held up even after other factors, like smoking, exercise and income were excluded.

Salty foods raise blood pressure, which adds to stroke risk. High sugar intake makes diabetes more likely, a disease that Southern food queen Paula Deen was diagnosed with last year. Being overweight ups the risk of stroke and diabetes.

Suzanne Judd, leader of the study, says that people eating Southern style were eating veggies, but not enough to counteract the bad effects of all that sugar, salt, and fat.

But subbing in just one serving of fruit, veggie, and whole grains each week would be enough to lower stroke risk for the worst of the Southern food junkies, Judd told The Salt. “Maybe cut back a little bit, so you’re not eating that every day.”

The results were presented at the American Stroke Association conference in Honolulu.

Scientists have lots of ideas about why people living in the Stroke Belt are more vulnerable, including poverty and African-American heritage. But none of them have been definitively linked.

But there’s no question that traditional Southern food, or soul food, is far from healthy. Efforts are underway to recast Southern classics with less fat, sugar, and salt.
