Strawberries improve brain speed and lower blood pressure

A recent study suggests that strawberries may help improve processing speed and lower blood pressure in older adults. However, they do not seem to greatly enhance overall cognitive function or vascular health. Researchers published their findings in the journal Nutrition, Metabolism, and Cardiovascular Diseases. They looked into how strawberries might affect cardiovascular health and brain function in older adults. Cardiometabolic diseases, which raise the risk of heart disease, are also linked to cognitive decline. Strawberries are nutritious, containing high levels of vitamin C and beneficial antioxidants. Some studies have indicated that their components can aid memory and learning. However, this latest research did not clarify the exact role of certain elements in strawberries, such as anthocyanins, which are believed to protect the brain. The study included older adults aged over 65 who were generally healthy. Participants consumed either a strawberry beverage or a control drink over two cycles of eight weeks. The research aimed to assess their cognitive abilities and cardiovascular health. Allergies to strawberries were noted as a potential downside for some individuals, with reactions possibly linked to specific proteins in the fruit. Results showed modest improvement in processing speed during the strawberry phase. Blood pressure readings were lower among those consuming strawberries, but the overall effects on cognition and heart health were limited. The researchers concluded that while there are some benefits from strawberries, the study's short duration and focus on healthy individuals mean the findings may not apply to those with existing health issues. The study was funded by the California Strawberry Commission.
