How Fast Food Affects Nutrition In Teens

Fast food can be a tempting option for meals, especially if your teenager has a busy schedule.

It is important to understand the problems it can cause, along with ways you can encourage your teen to make healthy choices at fast food restaurants.

Nutritious Foods

While eating fast food occasionally won’t affect her ability to obtain nutrients, eating it frequently or for most meals can be harmful.


Fast food’s large portions and high number of calories contribute to weight gain. According to the Academy of Nutrition and Dietetics, just one large soda and french fries can be more than 600 calories, which can be a considerable chunk of your teen’s recommended daily calorie intake. Regularly eating fast food can lead to obesity, which will place your teen at increased risk for obesity in adulthood.
