Blueberry Drinks Linked to Improved Mood in Children, Young Adults
Blueberries are high in flavonoids, particularly anthocyanins and flavanols. A recent study suggests that drinking flavonoid-rich blueberry drinks may help improve mood in children and young adults.
The study had two parts. The first part involved 21 young adults between the ages of 18 and 21 who were given a flavonoid-rich blueberry drink or a matched placebo. The second part involved 50 children who were given either a flavonoid-rich blueberry drink or a placebo.
In both parts of the study, the researchers used the Positive and Negative Affect Schedule to assess mood before consumption and two hours after consumption. The groups who drank the blueberry drink had increased positive affect but no change in negative affect.
A low positive affect is linked to depression and a high negative affect is linked to anxiety. The results of the study suggest that the effect of flavonoids on mood may be specific to depressive disorders rather than applying to different mood states.
Researchers from the University of Reading conducted the study. It was published on February 20, 2017 in Nutrients.
Previous studies suggest that they may help decrease the risk of dementia, aid in weight management, improve blood vessel function, lower blood pressure and reduce cholesterol.
Blueberries are easy to add to your diet because they go well with pancakes, salads and smoothies.
