A recent study published in the journal Nutrition, Metabolism, and Cardiovascular Diseases has shown that strawberries may positively impact heart health and brain function in older adults. The research, conducted among individuals over 65, indicated improvements in processing speed and a reduction in systolic blood pressure after regular consumption of this fruit.
Strawberries are known for their high vitamin C content—just 100 grams provide 65% of the recommended daily intake—as well as manganese, which is essential for metabolism and antioxidant protection. They are also a rich source of dietary fiber, polyphenols, and other beneficial compounds. Previous studies have already linked strawberry consumption to improved hippocampal function, which influences spatial learning, word recognition, and memory.
In the study, participants consumed two different beverages in separate periods—one containing strawberry extract and the other a placebo. The protocol was randomized and controlled, assessing cognitive performance and cardiovascular risk factors. Results showed that strawberries did not significantly affect body weight, BMI, or calorie intake but they improved information processing speed among participants. A slight decrease in systolic blood pressure was also observed, while cholesterol and blood sugar levels remained unchanged.
Scientists believe polyphenols in strawberries are responsible for these effects, but they emphasize that the study had a limited sample size and short duration. Nevertheless, the findings suggest that regular strawberry consumption could improve brain and heart health, particularly in older individuals.
