Eating vegetables cuts the risk of snoring.
Research has revealed that adopting a largely vegetarian diet can reduce the chance of developing obstructive sleep apnoea - the medical condition that causes heavy snoring.
Experts studied data from 14,120 people taking part in the US National Health and Nutrition Examination Survey, who provided information about what they ate in a day.
Those on diets high in junk food such as burgers and chocolate bars were up to 22 per cent more likely to suffer from heavy snoring.
Dr. Yohannes Melaku, author of the study at Flinders University in Australia, explained: "Risk factors for obstructive sleep apnoea may stem from genetics or behaviour, including diet. Previous research has primarily focused on the impact of calorie restriction, specific dietary elements and weight loss.
"There's a gap in our knowledge of how overall dietary patterns affect obstructive sleep apnoea risk. With this study, we wanted to address that gap and explore the association between different types of plant-based diets and the risk of obstructive sleep apnoea."
