A new research from New Zealand”s University of Otago has suggested that eating more fruit and vegetables may make young people calmer, happier and more energetic in their daily life.
Department of Psychology researchers Dr Tamlin Conner and Bonnie White, and Dr Caroline Horwath from Otago”s Department of Human Nutrition, investigated the relationship between day-to-day emotions and food consumption.
A total of 281 young adults (with a mean age of 20 years) completed an internet-based daily food diary for 21 consecutive days. Prior to this, participants completed a questionnaire giving details of their age, gender, ethnicity, weight and height. Those with a history of an eating disorder were excluded.
On each of the 21 days participants logged into their diary each evening and rated how they felt using nine positive and nine negative adjectives. They were also asked five questions about what they had eaten that day. Specifically, participants were asked to report the number of servings eaten of fruit (excluding fruit juice and dried fruit), vegetables (excluding juices), and several categories of unhealthy foods like biscuits/cookies, potato crisps, and cakes/muffins.
