Although it would be stating the obvious that fruit is better for you than potato chips, a new study from Aston University in Birmingham, England, found that eating healthy snacks rather than other options like potato chips can help stave off psychological and memory problems. The findings, which were published in the British Journal of Nutrition, found that those who ate fruit more often showed reduced symptoms of depression and greater positive psychological well-being. More frequent eating of potato chips and other savory snacks resulted in increased anxiety, depression, stress and reduced psychological well being. Eating a portion of fruit of any size was good for mental health.
