Nutrient requirements
A balanced diet is particularly important for 14-year-olds, as they experience rapid growth and development during their teenage years. Here are the nutrient requirements for a healthy diet:
Iron
Iron is essential for teenagers to support their growing bodies. Girls have higher iron requirements once they start menstruating, and iron can be found in animal sources such as meat, fish, and poultry. Plant-based sources include beans, peas, lentils, dark green vegetables, nuts, and seeds. To enhance iron absorption, include foods rich in vitamin C and avoid tea or coffee during meals.
Calcium
Calcium is crucial for the development of strong bones and teeth during adolescence. Aim for lower-fat dairy products, as they contain the same amount of calcium as full-fat versions. If opting for plant-based alternatives, ensure they are fortified with calcium.
Protein
Protein is necessary for growth and maintaining healthy muscles. Include meat, chicken, fish, or eggs in the diet to ensure sufficient protein intake. Fish is particularly important for brain, eye, and skin health. For vegetarians and vegans, plant-based sources such as beans, pulses, lentils, nuts, and seeds can provide alternative sources of protein.
Vitamins and Minerals
Vitamin D is essential for healthy bones, muscles, and teeth, and it aids in calcium absorption. The best source of vitamin D is sunlight, but it can also be obtained through supplements, especially during autumn and winter. Additionally, aim to include whole grains, fruits, vegetables, beans, eggs, fish, nuts, and lean meats in the diet to ensure a variety of vitamins and minerals.
Fluids
Adequate fluid intake is crucial for hydration and overall health. Encourage drinking water instead of flavoured waters or sports drinks to prevent weight gain and provide necessary hydration. Aim for six to eight glasses of fluid daily, including water, low-fat milk, and sugar-free drinks.

Food groups
A balanced diet is particularly important for 14-year-olds, who are in a period of rapid growth and development. A healthy diet should consist of well-balanced meals, rather than snacks that are high in fat, sugar, or salt.
Fruits and Vegetables
A 14-year-old should eat fruits and vegetables every day. The recommended amount is 2 cups of fruit and 2 1/2 cups of vegetables every day for a 2,000 calorie diet. These are good sources of vitamins, minerals, and fibre.
Whole Grains
Whole grains are an important part of a healthy diet. Examples include whole grain cereals, brown rice, whole wheat bread, and quinoa.
Dairy
Dairy products provide calcium, which is important for developing bones and teeth. Choose lower-fat options such as skimmed milk, or low-fat yoghurt, as these have the same amount of calcium as full-fat versions.
Protein
Protein is needed for growth and to keep muscles healthy. Include meat, chicken, fish, or eggs in your diet at least twice a day. Fish is particularly important for the brain, eyes, and skin. Try to eat fish 2 to 3 times a week. If you are vegetarian or vegan, you can get protein from beans, pulses, and lentils.
Healthy Fats
Include foods such as nuts, seeds, and avocados, which provide healthy fats that are important for overall health.

Meal frequency
The teenage years are a time of rapid growth and development, and a healthy, balanced diet is crucial to support these changes. Teenagers should focus on eating well-balanced meals instead of consuming too many snacks that are high in fat, sugar, or salt. It is recommended to choose lower-fat dairy products as they provide the same amount of calcium as full-fat versions. Calcium is essential for growing teens, and it is recommended that adolescents from 11 to 18 years old aim for adequate calcium intake each day.
Iron is another critical component of a teenager's diet, especially for girls who have started menstruating. Iron can be found in animal sources such as meat, fish, and poultry, as well as plant-based sources like beans, peas, lentils, dark green vegetables, nuts, and seeds. Vitamin C aids in iron absorption, so including foods rich in vitamin C is beneficial for vegetarians and vegans.
To maintain a healthy weight, teenagers should avoid filling up on sugary and fatty foods like crisps, sweets, cakes, and biscuits. Instead, they should opt for fresh fruits and vegetables, which provide vitamins, minerals, and fibre. Drinking six to eight glasses of fluid daily is also recommended, with water being the best option to stay hydrated and prevent constipation.
Breakfast is an important meal for teenagers as it can help with memory and concentration and provide energy throughout the day. Regular breakfast eaters tend to have a healthier weight than those who skip this meal. It is advised to choose high-fibre, low-fat cereals with minimal added sugar or salt for breakfast.
In conclusion, a 14-year-old should aim for three regular meals a day with healthy snacks to meet their nutritional needs. A balanced diet, adequate calcium and iron intake, and smart choices for snacks and drinks will contribute to their overall health and well-being during these formative years.

Iron-rich foods
Iron is an essential mineral for teenagers, especially girls, as it is a period of rapid growth and development, and girls start menstruating. Iron is needed to make haemoglobin, which is a substance in red blood cells that carries oxygen to the body's tissues. A deficiency in iron can lead to iron-deficiency anaemia, which can cause fatigue, reduced sports performance, impaired concentration, and an increased risk of injury.
To ensure your 14-year-old is getting enough iron, include iron-rich foods in their diet. Meat is a good source of iron, with red meats, steak, poultry, and fish being particularly recommended. If your teenager does not eat meat, there are still plenty of plant-based sources of iron. Dark green leafy vegetables, such as spinach, pulses, beans, nuts, and legumes are all iron-rich. Additionally, iron is added to some foods, such as infant formula and cereals. Fortified breakfast cereals can be a good source of iron for teenagers who don't eat meat.
To enhance the absorption of iron, pair iron-rich foods with those high in vitamin C. Citrus fruits, tomatoes, peppers, strawberries, red pepper, grapefruit, broccoli, and oranges are all good sources of vitamin C. It is also recommended to avoid tea and coffee with meals, as they contain tannins that reduce iron absorption.
While iron is essential for a healthy diet, it is important to be mindful that too much iron can lead to unpleasant side effects and even more serious issues. If you are concerned that your teenager is not getting enough iron from their diet, speak to a healthcare professional about supplements.

Calcium-rich foods
Calcium is an essential nutrient for teenagers, as it supports the development of healthy bones, teeth, and muscles. During the teenage years, bones grow in size and density, which is why young people have high calcium requirements. Calcium also helps the heart, nerves, and blood clot normally. Here are some calcium-rich foods that can be included in a 14-year-old's diet:
Dairy Products
Dairy products are a great source of calcium, and choosing lower-fat options is generally recommended. These include:
- Milk: Opt for no-fat or low-fat milk, which provides the same amount of calcium as full-fat milk but with fewer calories and fat.
- Cheese: Varieties such as cheddar, Swiss, mozzarella, and Parmesan are good sources of calcium.
- Yogurt: Plain or flavoured yogurt can be a tasty and calcium-rich addition to meals or snacks.
Dark, Leafy Greens
Dark, leafy green vegetables are not only a good source of iron but also contain calcium. Some options include:
- Kale
- Collard greens
- Broccoli
- Bok choy
- Spinach
Calcium-Fortified Foods
Some foods are fortified with calcium during processing, which means extra calcium has been added. These can be a great way to boost calcium intake, especially for those following a vegan or vegetarian diet. Examples include:
- Fortified breakfast cereals: Look for options that are fortified with calcium and are low in added sugar and salt.
- Fortified plant-based milk alternatives: Check the labels to ensure the product contains added calcium.
- Fortified juices and tofu: These can also be good sources of calcium.
Other Calcium-Rich Foods
There are also other foods that naturally contain calcium and can be incorporated into meals or snacks:
- Beans
- Lentils
- Tofu (depending on the type)
- Nuts and seeds: Almonds, Brazil nuts, and sesame seeds are particularly good sources.
- Fish with edible bones: Sardines and canned salmon, for example, can be eaten with the bones, providing a good source of calcium.
It is worth noting that vitamin D is important for calcium absorption, so getting enough sunlight or considering a supplement, especially during autumn and winter, can help ensure your body makes the most of the calcium in your diet.

Frequently asked questions
A balanced diet for a 14-year-old should include a variety of foods from the five main food groups: fruits and vegetables, grains, proteins, dairy, and healthy fats. It is important to eat whole grains, fruits, vegetables, lean meats, eggs, fish, nuts, beans, and low-fat dairy products.
Iron is essential for teenagers as it helps their bodies grow and develop. Iron is needed to make red blood cells, which carry oxygen around the body. If you are menstruating, you will lose iron, and if you do not get enough, you can develop anaemia, which can make you feel tired and lightheaded. Good sources of iron include red meat, fish, poultry, beans, peas, lentils, nuts, seeds, and fortified breads and cereals.
Calcium is important for healthy bones and teeth, especially during the teenage years when bones are growing in size and density. Good sources of calcium include low-fat dairy products such as milk and yoghurt, as well as calcium-fortified plant-based alternatives.
Sugary foods and drinks, such as sweets, cakes, biscuits, and fizzy drinks, should be limited as they are high in calories and can lead to weight gain and tooth decay. From the age of 11, it is recommended to limit sugar intake to no more than 30g of sugar per day.
Healthy snacks for teenagers include fruits and vegetables, rice cakes with cheese, toast with a spread, or a fruited teacake. It is also important to stay hydrated by drinking water instead of sugary drinks.
