You've probably read about how having an unhealthy diet could increase your risk for all sorts of serious illnesses from heart disease to cancer. So it would be natural to assume eating healthily would help you live longer, right?
So eating your greens now may help you reap the benefits when you're older.
The researchers defined a healthy foods diet as one that comprises low-fat dairy foods, fruit, whole grains, poultry, fish and vegetables, with just a small amount of meat, fried foods, sweets, high-calorie drinks and added fat (and vice versa for an unhealthy foods diet).
The study analysed the eating patterns of more than 2,500 people over a 10-year period. The results, claims Amy Anderson, the study's lead author, suggest that adults who eat "relatively high amounts of vegetables, fruit, whole grains, low-fat dairy products, poultry and fish may have a lower risk of mortality".
Eating healthily can be tricky, however, with many foods that claim to be healthy really having hidden high levels of salt, sugar and fat. So when it comes to diet, it pays to read the labels to make sure you really are taking the healthy option.
Are you going to attempt to eat healthily over the holiday season?
