The findings from the randomised clinical trial presented at the Nutrition 2023 conference of the American Society of Nutrition (ASN) suggest that daily strawberry consumption is associated with various health benefits. The study, conducted at San Diego State University, focused on healthy individuals between the ages of 66 to 78.
During the trial, the participants consumed 26 grams of freeze-dried strawberry powder, equivalent to two servings of strawberries daily, or a control powder for eight weeks each. The trial was double-blind and placebo-controlled to ensure accurate results.
The results showed that daily strawberry consumption led to the following positive effects:
- Improved Cognitive Performance: Cognitive processing speed increased by 5.2%, indicating potential benefits for brain health and cognitive function.
- Reduced Blood Pressure: Systolic blood pressure decreased by 3.6%, suggesting potential cardiovascular health benefits.
- Higher Antioxidant Capacity: Total antioxidant capacity increased by 10.2%, which indicates an improvement in the body’s ability to combat oxidative stress.
Additionally, waist circumference decreased by 1.1% during both the control and intervention arms of the trial, suggesting potential metabolic benefits. However, it’s important to note that participants experienced increased serum triglycerides while consuming the control powder.
Strawberries are rich in bioactive compounds, providing various health benefits. They are a good source of vitamin C, folate, potassium, fiber, phytosterols, and polyphenols, all of which contribute to heart-healthy nutrients.
“This study demonstrates that consuming strawberries may promote cognitive function and improve cardiovascular risk factors like hypertension,” stated Shirin Hooshmand, professor in the School of Exercise and Nutrition Sciences at San Diego State and principal investigator on the study. “We’re encouraged that a simple dietary change, like adding strawberries to the daily diet, may improve these outcomes in older adults.”
Previous clinical trials have also linked strawberry consumption to improvements in cardiovascular health, including reduced total and LDL cholesterol levels and lower blood pressure. Furthermore, several studies have explored the connection between strawberry consumption and brain health, showing potential benefits for reducing the risk of Alzheimer’s dementia.
Long-term observational studies, such as the Health Professionals Study and the Nurses’ Health Study, have also found that individuals who consume strawberries regularly tend to have lower rates of cognitive decline.
The study adds to the existing body of research supporting the health advantages of incorporating strawberries into one’s diet. However, it’s essential to consider individual dietary needs and preferences when making dietary choices.
