A new study involving twins from the US, Australia, Denmark, and Sweden found a correlation between higher consumption of fruits and vegetables and a reduced risk of depression. Participants with higher intakes of fruits and vegetables (2.1 servings of fruit and 2.0 servings of vegetables daily) experienced a lower incidence of depression compared to those with lower intakes (0.3 servings of fruit and 0.5 servings of vegetables daily).
over time, according to a comprehensive new study of twins that included participants across the US, Australia, Denmark, and Sweden.Led by researchers from the University of New South Wales in Australia, the study analyzed survey data on diet and mood from 3,483 individuals. All the participants were aged 45 and above, with follow-up periods of up to 11 years.
"One of the advantages of the twin design is that it can help address the issue of unwanted factors, such as socioeconomic status early in life, influencing the results."between those classed as having a high fruit and vegetable intake , and those with a low fruit and vegetable intake . When moderate vegetable and fruit intakes were compared to low intakes, the difference in depression was less pronounced for vegetable consumption, and nonexistent with fruit intake."We found that fruit and vegetable consumption in the two large Scandinavian studies were particularly low, with the average for both being less than half the"We are unclear what the reduction in depression scores would be if intakes were increased to recommended levels.
Although the data isn't detailed enough to prove cause and effect – physical activity, for example, wasn't included in the analysis – the relatively large sample size and the use of twins counts in the study's favor, suggesting there is a connection here. "This study's finding of a protective association between higher fruit and vegetable intake and depressive symptoms is consistent with most prior evidence," the teambetween the ages of 55 and 75, and this research suggests eating more fruit and vegetables is potentially a simple way of tackling that.
