London:  What is your New Year resolution? Well, if you choose a healthy one, you are more likely to end up being even more virtuous, says a new study.

Researchers at the National Centre for Social Research (NatCen) in the UK found that people who make healthy changes to their life tend to get other benefits tag along for free.

Positive changes, according to them, have a domino effect meaning non-smokers tend to eat less fatty food and those who quit cigarettes may like to eat more fruit and vegetables.

While healthy habits breed more healthy habits, the same was found with vices, according to the study which was carried out for the UK's Department of Health.

People who regularly ate fried food were more likely to eat too much salt and people who consumed too much alcohol also ate fewer fruit and vegetables.

Chief Medical Officer, Prof Dame Sally Davies said: "The New Year is a great time to renew efforts and give up unhealthy habits, such as smoking, and take up healthier ones, such as regular physical activity, improving our diet and drinking less.

"This NatCen research shows that if you make one healthy resolution this New Year you might get double the benefits as you are more likely to make other positive healthier changes too. So, start thinking about other areas where you can improve your health and set yourself up for a healthier life, for 2012."
