‘Gateway’ foods: Ultra-processed foods leading to unhealthy teen diets

2 mins read Children's dentistry Diet and nutrition
Research presented at the American Heart Association’s Hypertension Scientific Sessions 2022 suggests that ultra-processed foods might act as a “gateway” causing teenagers to eat higher quantities of unhealthy foods.

In discussions around mouth health there has always been a correlation between sugary or ultra-processed foods and negative impacts on oral health. In recent months, the UK has seen debates around sugary children’s snacks particularly.

Research suggests that ultra-processed foods (foods high in sugar, salt, unhealthy trans-fat, artificial flavours and colours) account for approximately 60 per cent of the average American diet. A 2019 study published in the BMJ suggests that the figure is slightly lower in the UK at 56.8 per cent.
