Researchers studied 35 older adults in four visits over the course of five months and looked at whether consuming more strawberries daily improved their cognitive function and cardiovascular health.
Before each visit, the participants were told not to eat or drink overnight for at least 10 hours and avoid alcohol, caffeine and strenuous exercise.
They were then told to consume 26 grams of freeze-dried strawberry powder (equivalent to two cups of fresh strawberries) mixed with about 8 ounces of water for eight weeks. Then, they repeated the process with a control powder that mimicked the strawberry powder's flavor and macronutrients.
According to the study, which was published in the journal Nutrition, Metabolism and Cardiovascular Diseases, the participants' cognitive processing speed improved after consuming the strawberry powder drink. They also had lowered blood pressure, the results showed.
The benefits of strawberries were linked to phytochemicals that play a role in reducing oxidative stress and inflammation, researchers stated.
The study was conducted by Kristin Delaney, Michelle Tsang, Mark Kern, Vernon Uganiza Rayo, Nathaniel Jason, Mee Young Hong, Changqi Liu and Shirin Hooshmand of the School of Exercise and Nutritional Sciences at SDSU.
