Kelvin asks: What is the world's unhealthiest food?
Wynnie says: There are no truly 'good' or 'bad' foods - just unhealthy eating habits. Rather than categorising foods as good and bad or healthy and unhealthy, we should focus on our overall diet.
Eating food you enjoy is crucial to maintaining a healthy diet and lifestyle. If you really like crisps or chocolate, there is no reason you can't indulge if you have an otherwise balanced approach to food. The key is moderation.
Adolescence is a period of rapid growth, so the nutrient and energy needs of teenagers are higher than those of any other age group, especially teens who are particularly active.
It's vital that you eat nutrient-dense and well-balanced meals to satisfy your healthy appetite. Just because a teen's energy needs are high, that doesn't give you the licence to munch on sugary or fatty snacks every day - your nutrient intake can be seriously compromised.
A healthy diet for a teen should therefore be based on as wide a range of foods as possible. There are five food groups which form part of a balanced diet.
Bread, rice, potatoes, pasta. This group is rich in complex carbohydrates. It also includes breakfast cereal, noodles, oats and barley, and should form the basis of most of your meals - eat at least four portions a day.
