The teenage years are a time of rapid growth and development, and a healthy, balanced diet is particularly important. Teenagers have different nutritional needs than adults, requiring a steady supply of calories and nutrients to support their growth. Eating healthily means getting the right balance of nutrients, including protein, calcium, iron, vitamins, and minerals. A diet high in nutrient-dense foods is best, while still enjoying treats in moderation. A balanced diet can support energy levels and overall health, while an unhealthy diet can negatively affect mood, energy levels, and academic and sports performance.

What You'll Learn
The importance of iron, calcium, and vitamins
During the teenage years, a healthy balanced diet is particularly important as it is a time of rapid growth and development. Teenagers should be aiming for at least an hour of physical activity every day, eating fewer fatty foods, and drinking six to eight glasses of fluid every day.
Iron
Iron is a mineral found in plants and animals and is an important component of haemoglobin, the part of red blood cells that carries oxygen from the lungs to the rest of the body. Iron-rich foods include meat, fish, and poultry, as well as dried beans, seeds, nuts, and leafy green vegetables like kale. Iron is also added to some foods, such as infant formula and cereals. It is especially important for teenage girls as they start menstruating.
Calcium
Calcium requirements are also high during the teenage years to build strong bones and fight bone loss later in life. Good sources of calcium include dairy products such as low-fat milk, yoghurt, cheese, and cottage cheese, as well as broccoli and dark green leafy vegetables. Calcium-fortified tofu, soy milk, tempeh, soy yoghurt, and cooked soybeans (edamame) are also good options.
Vitamins
Vitamins are organic substances made by plants or animals and are essential for the body to work properly. They fall into two categories: fat-soluble (vitamins A, D, E, and K) and water-soluble (vitamin C and the B-complex vitamins). A well-rounded diet that includes a variety of whole-grain products, fresh fruits and vegetables, dairy products, nuts, seeds, eggs, and meats will provide most people with the vitamins and minerals their body needs.

The dangers of ultra-processed foods
During the teenage years, a healthy balanced diet is particularly important as it is a period of rapid growth and development. Teenagers should be aiming for at least an hour of physical activity every day, and eating fewer fatty foods such as chips, burgers, fried food, and processed foods like instant noodles.
Ultra-processed foods are edible products made from industrially manufactured ingredients that have been extracted from foods, processed, and then reassembled to create shelf-stable, tasty, and convenient meals. These include packaged snacks, ice cream, soft drinks, energy drinks, canned soups, packaged meat, fish, vegetables, bread, breakfast cereals, sweetened juices, margarines, and spreads.
To avoid the dangers of ultra-processed foods, it is important to eat a balanced diet with whole grains, fruits, and vegetables, and to limit the consumption of foods and drinks that are high in added sugars, saturated fats, and sodium.

The influence of peers and social media
Adolescence is a critical period of rapid growth and development, and a healthy, balanced diet is crucial for teenagers to meet their nutritional requirements. Teenagers are vulnerable to various influences when it comes to their dietary choices, and peers and social media play a significant role in shaping their eating behaviours.
The Influence of Peers
Peers have a substantial impact on adolescent eating habits. Teenagers often look to their friends and peers when deciding what and how to eat. This influence can be positive or negative, depending on the dietary habits of their peers. Research has shown that adolescents with healthier peer groups tend to have better dietary patterns themselves. For example, if their peers are perceived to engage in healthy eating behaviours, it can positively influence their own eating habits. Conversely, if their peers have unhealthy eating habits, it can reinforce poor dietary choices.
The Influence of Social Media
Social media has emerged as a powerful force in shaping the dietary behaviours of teenagers. With over 90% of adolescents active on social media platforms, they are exposed to a multitude of influences that can impact their relationship with food. Social media platforms are often flooded with unrealistic images and idealised body types, which can lead to negative body image and body dysmorphia. This pressure to conform to unrealistic beauty standards can result in unhealthy dieting practices and, in some cases, contribute to the development of eating disorders.
Additionally, social media platforms are used extensively by food and beverage brands to market their products directly to adolescents. These advertisements often feature celebrities and influencers promoting unhealthy food choices. Adolescents are more likely to recall these unhealthy food advertisements, and the celebrity influence further reinforces their impact. The combination of peer influence and social media marketing creates a complex environment that can make it challenging for teenagers to develop a healthy relationship with food.
Furthermore, social media platforms provide a space for user-generated content related to food. While this content is different from traditional food advertisements, it often depicts high-calorie, nutrient-poor foods, with only a small percentage showcasing fruits and vegetables. This type of content can normalise and encourage unhealthy eating habits among teenagers.
In conclusion, peers and social media have a profound influence on the dietary habits of teenagers. It is essential to recognise the potential harm caused by negative influences and to promote positive, healthy messages through social media platforms to support adolescents in making informed and nutritious food choices.

The impact of diet on skin health
The skin is the body's largest organ, and its health is influenced by various factors, including diet and nutrition. Eating a well-balanced diet that includes a variety of whole foods is essential for maintaining healthy skin and promoting skin renewal.
The role of diet in skin health
Dermatologists agree that diet plays a critical role in skin health. A healthy diet provides the body and skin with essential nutrients such as vitamins, minerals, antioxidants, proteins, and healthy fats. These nutrients work together to nourish the body and support the skin's natural processes of renewal and protection.
Common skin concerns associated with diet
An unhealthy diet high in sugar, dairy, refined carbohydrates, and processed foods can negatively impact the skin, leading to increased breakouts, premature aging, dryness, and hyperpigmentation.
- Increased Breakouts: Diets high in sugar, dairy, and refined carbs cause spikes in insulin, leading to increased oil production and clogged pores, resulting in more frequent and severe acne.
- Premature Aging: A lack of antioxidants in the diet can lead to oxidative stress, causing wrinkles, fine lines, and loss of elasticity. High sugar intake can also damage collagen, causing the skin to sag and wrinkle prematurely.
- Dryness and Dehydration: Not consuming enough healthy fats, such as omega-3s, can leave the skin feeling dry, flaky, and prone to irritation.
- Hyperpigmentation: Excessive sugar intake and processed foods have been linked to increased dark spots and uneven skin tone. Poor diet choices can also make the skin more susceptible to sun damage.
Nutrient-rich foods for skin health
To support skin health, it is essential to incorporate nutrient-rich foods into your diet:
- Antioxidants: Fight off free radicals that damage skin cells and accelerate aging. Antioxidants are found in colorful fruits and vegetables like blueberries, leafy greens (spinach, kale), and nuts and seeds (almonds, walnuts).
- Vitamins: Leafy greens, nuts, and seeds are rich in vitamins A, C, and E, which help maintain skin health and protect against oxidative stress.
- Healthy Fats: Omega-3 fatty acids help maintain skin moisture, preventing dryness and irritation.
- Water: Staying hydrated is crucial for maintaining skin moisture and flushing out toxins that can cause breakouts. Aim for at least 8 glasses of water per day.
Teenagers and diet
During the teenage years, a healthy balanced diet is particularly important due to the rapid growth and development that occurs during this time. Teenagers should aim to eat well-balanced meals from the five main food groups, including iron-rich foods, calcium-rich foods, and vitamin D sources. They should also limit their intake of fatty, sugary, and salty foods and aim for at least an hour of daily physical activity.

How to maintain a healthy weight
As a teenager, it is important to maintain a healthy weight by eating a well-balanced diet that meets your energy needs. Here are some tips to help you achieve and maintain a healthy weight:
Eat a Variety of Nutrient-Dense Foods
Include a variety of whole grains, fruits, vegetables, lean proteins, and healthy fats in your diet. Aim for at least 2 cups of fruit and 2 1/2 cups of vegetables every day. Choose whole grains such as brown rice, whole-wheat bread, and oats. Opt for lean meats, fish, chicken, and plant-based sources of protein like beans, lentils, and nuts.
Get Enough Calcium and Vitamin D
During adolescence, your body has high calcium requirements due to rapid growth and development. Include calcium-rich foods such as low-fat or fat-free milk, yogurt, cheese, spinach, and fortified plant-based beverages. Vitamin D is also crucial for healthy bones, and the best source is sunshine. Consider taking a daily supplement, especially during autumn and winter.
Limit Processed and Sugary Foods
Ultra-processed foods, sugary drinks, and snacks are high in added sugars, saturated fats, and salt, which can negatively impact your health. Limit your intake of desserts, sweets, fried foods, and fast food. Instead, opt for natural sweeteners like fruit, and choose baked or broiled foods over fried options.
Stay Hydrated
Drink plenty of water throughout the day to stay hydrated and maintain your energy levels. Avoid sugary drinks and flavoured waters, as they can contribute to weight gain and provide empty calories. Water will help you stay hydrated without adding extra calories.
Be Physically Active
In addition to a healthy diet, regular physical activity is essential for maintaining a healthy weight. Aim for at least 60 minutes of moderate to vigorous physical activity every day. This can include activities like walking, cycling, sports, or any form of movement you enjoy.
Remember, it's important to consult with a healthcare professional or a registered dietitian if you have specific concerns or need personalised advice regarding your diet and weight.
