Men living alone were more likely to have a poor diet than women, researchers from the Queensland University of Technology (QUT) have found.
Dr Katherine Hanna and Dr Peter Collins, from QUT's School - Exercise and Nutrition Sciences, analysed 41 previous studies to investigate the link between living alone and food and nutrient intake.
"Our results found that people who live alone have a lower diversity of food intake and a lower consumption of some core food groups like fruits and vegetables and fish," Hanna said.
"For example, a lack of motivation and enjoyment in cooking and/or eating alone often led to people preparing simple or ready-made meals lacking key nutrients.
"The absence of support or encouragement to comply with healthy eating guidelines and difficulty in managing portion control were also factors influencing diet," Hanna said.
Hanna said people living alone were diverse in range of age, gender, education and socioeconomic status but could be unprepared for cooking for themselves for a range of reasons.
"Economic factors also explain lower consumption of foods like fruits and vegetables and fish, as they require more frequent purchase and consumption, which can be expensive.
"The psychological impacts of living alone can also influence diet. Previous research has found loneliness, for example, is a significant predictor of malnutrition in the elderly," Hanna said.
The study has been published in the journal Nutrition Reviews.
