Healthy eating for teens

A healthy diet can help you look and feel great. Don't follow the latest food fad: find out the truth about eating well.

Your body needs energy and nutrients from food to grow and work properly. If you don't eat a healthy, balanced diet, you could be putting your health and growth at risk.

A healthy diet also gives you the energy you need and can help you look and feel great. But eating well doesn't have to mean giving up all your favourite foods. A healthy diet means eating a wide range of foods so that you get all the nutrients you need, and eating the right number of calories for how active you are.

Beware of fad diets: they're rarely the best way to reach a healthy weight. Instead, use our tips to help you eat more healthily.

Get started

  • Don't skip breakfast. Some people skip breakfast because they think it will help them lose weight. But skipping meals doesn't help you lose weight and is not good for you, because you can miss out on essential nutrients. Research shows that eating breakfast can actually help people control their weight. In addition, a healthy breakfast is an important part of a balanced diet and provides some of the vitamins and minerals we need for good health. Whole grain cereal with fruit sliced over the top is a tasty and healthy start to the day.
  • Aim to eat at least five portions of a variety of fruits and vegetables a day. They are good sources of many of the vitamins and minerals your body needs. It's not as hard as it might sound: fresh, frozen, tinned, dried and juiced fruit and vegetables all count towards your total. So one glass (150ml) of fruit juice, smoothies and vegetables baked into dishes such as stews all count. Learn more at Why 5 A DAY?
  • At snack time, swap foods that are high in saturated fat or sugars for healthier choices. Foods high in saturated fat include pies, processed meats such as sausages and bacon, biscuits and crisps. Foods high in added sugars include cakes and pastries, sweets, and chocolate. Both saturated fat and sugar are high in calories, so if you eat these foods often you're more likely to become overweight. Too much saturated fat can also cause high cholesterol. Learn more in Eat less saturated fat.
  • Make sure you drink enough fluids. Aim to drink six to eight glasses of fluids a day: water and milk are all healthy choices. Even unsweetened fruit juice is sugary, so try to drink no more than one glass (about 150ml) of fruit juice each day.
  • If you're feeling tired and run down, you may need more iron in your diet. Teenage girls are at higher risk of being low on iron, because they lose iron when they have their monthly period and they are still growing. Good sources of iron include red meats, breakfast cereals fortified with iron, and baked beans. Learn more in Anaemia, iron deficiency.
  • If you often feel hungry, try eating more high-fibre foods such as wholemeal bread, beans, wholegrain breakfast cereals, fruit and vegetables. Foods that are high in fibre are bulky and help us to feel full for longer, and most of us should be eating more of them.
  • If eating makes you feel anxious, guilty, or upset, or you're often worried about food or your weight, you may have an eating disorder. Help is out there: tell an adult you trust. Learn more in Eating disorders explained.
  • If you are underweight, you may not be eating enough. Restricting foods (or food groups) or not eating a balanced diet can stop you getting enough of the calories and other important nutrients your body needs. This can lead to weight loss. Being underweight can cause health problems, so if you're underweight it's important to gain weight in a healthy way. Your GP can help with this.
  • If you are overweight, you may be eating too much. Foods high in fat and sugar are high in calories, and eating too many calories can lead to weight gain. Try to eat fewer foods that are high in fat and sugar, such as swapping to low- or no-sugar fizzy drinks. A healthy balanced diet will provide you with all the nutrients your body needs. Your body mass index (BMI) can tell you whether you are a healthy weight – check yours with our BMI healthy weight calculator.
  • Don't follow fad diets. If you have an overweight BMI, aim to lose weight to bring your BMI into the healthy range. If you want to lose weight, it's important to choose your diet plan carefully. It can be tempting to follow the latest fad diet, but these are often not nutritionally balanced and don't work in the long term: once you stop, the weight is likely to come back. Diets based on only one or two foods may be successful in the short term, but can be dull and hard to stick to and deficient in a range of nutrients. The healthier, long-term way to lose weight is by combining long-term changes towards a healthy, balanced diet with more physical activity. If you're concerned about your weight, your GP can help.
  • Watch out for "low-carb" diets, or any eating plans that advise you to cut out whole food groups. This can be unhealthy, because you may miss out on nutrients from that food group. Low-carb diets can be high in saturated fat. Eating too much saturated fat can cause high cholesterol, which can lead to an increased risk of developing heart disease. Other diets may involve cutting out dairy foods such as milk, yoghurt and cheese. These foods are high in calcium, which you need to ensure your bones grow properly. Choose lower fat dairy foods when you can – semi-skimmed, 1% fat or skimmed milk contain all the important nutritional benefits of whole milk, with less fat.

Please dont listen to the 2 comments below mine.

Whilst some parts of their posts may be partialy true, its in no way sensible or healthy to follow a low carbohydrate/ high fat lifestyle.

The key point the previous 2 commentators missed.... the above information is aimed a pemanent lifestyle not a diet.

No one is suggesting sugar is good for you but to over simplify metabolism and suggest all carbohydrates are sugar for the sake of a 1 sided arguement is irresponsable.
as is stating that fat wont make you fat , it contains twice as many kcals as carbohydrates and certainly can make you fat if over consumed.

Follow the above advice to maintain a healthy weigth, it may not help you lose lots of weight if your already overweight but its a long term ideal lifestyle.

I think that it is high time that both the government and the nhs stop lying to us about what is healthy and what is not, and that losing weight is merely a matter of choosing to eat a little less/ a little "healthier". No one like being fat. It's uncomfortable, dangerous, and makes you feel bad about yourself. Surely if it was a matter of simply choosing not to be fat, the obesity epidemic would not be taking over the UK. I cannot believe that it still says on this website that we should beware of Low Carb diets and that fat is bad for you! The body processes carbs as sugar and stores anything not burned immediately as fat. Fat, however, is slow burning, and the is not an addictive substance such as sugar (what carbs are.) and does not trigger the same brutal dopamine response. Science has disproven the cherry picked experiments of decades ago that sugegestd that high carb were good, but in order to save the money making, sugar based companies the government keeps pushing carbs! This is false information and it is ridiculous and frankly disgusting that in this day and age we think that it acceptable to lie to a whole country when we know the truth. We don't claim that smoking is good for you, so we should stop claiming that carbs are.

I can't believe the NHS is still telling us to do the exact opposite of what we should be doing. We're now officially the most obese country in Europe and I definitely believe the NHS has played a major part in this.

Low carb, high fat (especially saturated fats) is the only healthy way to lose weight. Fat keeps you full, whereas carbs keep you full for a short while, before you "crash" and feel hungry again (the same goes for sugar). Carbs also stop the body burning up fat properly, which is why you get fat if you eat a high amount of fat and carbs. But limit your intake of carbs (and eat lots of fat and vegetables to keep you full instead) and you'll start losing a lot more weight than if you tried to eat less fat. Fat does not make you fat - carbs do.

Sweden started recommending a low carb, high fat diet, based on a review of 16,000 studies.

And for those who are concerned about saturated fats "raising cholesterol" - there hasn't been a single study that has proven or even given very strong evidence for there being a link between saturated fats and raised cholesterol. Not one.

Wake up Britain.

heyy reader

to be honest i think that healthy eatings great at my age (14) i think that it's great because it decreases the risk of having a heart disease/ a coronary heart disease or a high blood pressur to be honest neither a cholesterol level it's always bad to start off eating a lot at the age of teenagers because to be honest you may think you look big as in getting fatter so im not saying don't eat because you'll get fat all im saying is that eating heathier is better but! if you still chose to eat food with saturated fat I suggest hit the gym or run on the tredmill or do leisure activities and if not them do school activities like rounders you can be trained up for a rounders tournament etc... you may think it's boring but to be honest it'd worth it than trying it at the age of 36+ trust me my mums trying...
