Strawberries Boost Cognitive Function, Heart Health in Seniors, Study Finds

Strawberries may improve cognitive processing and cardiovascular health in adults aged 65 and older, according to new research.

A study by researchers at San Diego State University, published in the journal Nutrition, Metabolism and Cardiovascular Diseases, found that elderly participants who consumed strawberries showed improved cognitive processing speed and enhanced antioxidant capacity. The study also demonstrated blood pressure regulation effects, with lower systolic blood pressure observed in the strawberry group.

The research team divided 35 healthy adults aged 65 and older into two groups. One group consumed strawberry powder for eight weeks, while the control group received nutritionally similar food products.

Results showed the strawberry group experienced faster cognitive processing speed, reduced blood pressure, and improved antioxidant function. While triglyceride levels increased in the control group, no significant change was observed in the strawberry group.

"Polyphenols, anthocyanins, and ellagitannins in strawberries likely contributed to improvements in cognitive function and cardiovascular health among older adults," the researchers said.

The team noted that additional research is needed to determine whether the same benefits apply to seniors with existing cardiovascular disease or cognitive decline, as the study involved only healthy elderly participants.

Other fruits have also shown cardiovascular benefits. Research indicates that consuming blueberries three or more times weekly reduces heart attack risk by 32%. Regular pomegranate consumption has been shown to lower systolic blood pressure by 5-8 mmHg.

Pectin and polyphenols in apples block intestinal cholesterol absorption and help prevent vascular disease. Potassium-rich fruits such as bananas and oranges aid sodium excretion, effectively regulating blood pressure.
