Eating fruit is good for your well being. Who Knew?

A recent study surveyed 428 adults and looked at the relationship between their consumption of fruit, vegetables, and sweet and savoury food snacks and their psychological health. The more often people ate fruit, the lower they scored for depression and the higher for mental well-being.

According to new research from the College of Health and Life Sciences, Aston University, people who frequently eat fruit are more likely to report greater positive mental wellbeing and are less likely to report symptoms of depression than those who do not,

The researchers’ findings suggest that how often we eat fruit is more important to our psychological health than the total amount we consume during a typical week. The team also found that people who eat savoury snacks, which are low in nutrients, are more likely to report greater levels of anxiety.

After taking demographic and lifestyle factors such as age, general health and exercise into account, the research found that both nutrient-rich fruit and nutrient-poor savoury snacks appeared to be linked to psychological health. They also found that there was no direct association between eating vegetables and psychological health.

Based on the survey, the more often people ate fruit, the lower they scored for depression and the higher for mental wellbeing, independent of the overall quantity of fruit intake.

People who frequently snacked on nutrient-poor savoury foods were more likely to experience ‘everyday mental lapses’ (known as subjective cognitive failures) and report lower mental wellbeing. A greater number of lapses was associated with higher reported symptoms of anxiety, stress and depression, and lower mental wellbeing scores.

By contrast, there was no link between these everyday memory lapses and fruit and vegetable intake or sweet snacks, suggesting a unique relationship between these nutrient-poor savoury snacks, everyday mental lapses, and psychological health.

Examples of these frustrating little everyday mental lapses included forgetting where items had been placed, forgetting the purpose of going into certain rooms, and being unable to retrieve names of acquaintances whose name was on the ‘tip of the tongue’.

Other studies have found an association between fruit and vegetables and mental health, but few have looked at fruit and vegetables separately – and even fewer evaluate both frequency and quantity of intake.

Both fruit and vegetables are rich in antioxidants, fibre and essential micronutrients which promote optimal brain function, but these nutrients can be lost during cooking. As we are more likely to eat fruit raw, this could potentially explain its stronger influence on our psychological health.

“It is possible that changing what we snack on could be a really simple and easy way to improve our mental wellbeing. Overall, it’s definitely worth trying to get into the habit of reaching for the fruit bowl.
