Eating home cooked meals may keep diabetes away: study

People who often eat food prepared at home are less likely to suffer from type 2 diabetes than those who consume such meals less frequently, new research has claimed.
There is an increasing tendency for people to eat out, and this could involve consumption of fast food, for example, researchers said.
Concerns have been raised that such people have a diet that is rich in energy but relatively poor in nutrients - this could lead to weight gain which is, in turn, associated with an increased risk of type 2 diabetes, said Qi Sun, from the Harvard T H Chan School of Public Heath in the US.

There has been little authoritative research investigating the role that preparing meals at home may play in altering the long term risks of developing diabetes and/or obesity.
Sun and colleagues employed large prospective datasets in which US health professionals - both men and women - were followed-up for long periods, with rigorous collection of data on health indicators, including self-reported information on eating habits and occurrence of diabetes.
The results were corrected for various known factors that could affect dining habits, including marital status. The study analysed 2.1 million years of follow-up data.

The findings indicate that people who reported consuming 5-7 evening meals prepared at home during a week had a 15 per cent lower risk of type 2 diabetes than those who consumed 2 such meals or fewer in a week.

A smaller, but still statistically significant, reduction was apparent for those who reported consuming more midday meals prepared at home, researchers said.
Other analyses suggest that less weight gain could partially explain the reported reduction in occurrence of type 2 diabetes in those often eating meals prepared at home.
Well-established diabetes prevention strategies include behavioural interventions aimed at increasing exercise and improving dietary habits.
The findings suggest that the nutritional and lifestyle benefits of consuming meals prepared at home could contribute to these diabetes prevention efforts.
The research was published in the journal PLOS Medicine.
