Scientists Link One Everyday Drink to Lower Depression Scores

A new study published in the British Journal of Nutrition suggests that including a daily glass of 100 percent fruit juice or a smoothie in one's diet may be linked to lower depression scores. Researchers from Newcastle University investigated the impact of increasing fruit and vegetable intake, with some participants adding fruit juice or smoothies to their daily routine.

After four weeks, those who consumed the juices or smoothies alongside whole fruits reported a 2.52-point drop on a 27-point depression scale compared to the control group. The study's principal investigator, Dr. Anthony Watson, explained that fruit juice and smoothies can provide concentrated sources of compounds like vitamin C and flavonoids, which have been linked to brain health.

Dr. Noura Filali, a medical doctor not involved in the study, pointed to the potential of polyphenols and flavonoids, particularly in citrus juices, to have antioxidant and anti-inflammatory effects that may influence brain function. Dr. Oliver Shannon, another senior author, emphasized that the findings warrant further investigation, as simple dietary changes like increasing fruit intake could support mental well-being.
