Healthy eating during adolescence is critical because it fuels the second-fastest growth spurt of a human life, establishes lifelong dietary habits, and prevents serious long-term health conditions. Between the ages of 12 and 19, the body undergoes rapid physical development, hormonal shifts, and brain maturation, all of which demand an immense amount of high-quality energy and targeted nutrients. Proper adolescent nutrition serves four primary functions: 1. Supporting Rapid Physical Growth and Brain Development - Bone Building: Nearly 50% of adult skeletal mass is formed during early adolescence. Consuming enough calcium and vitamin D is necessary to maximize bone mineral density and lower the risk of osteoporosis in later years. - Muscle and Blood Volume Expansion: The sharp increase in lean body mass in boys and the onset of menstruation in girls create a high demand for iron. Meeting this need protects teenagers from iron-deficiency anemia, which causes severe fatigue and weakness. - Cognitive Function: Essential fatty acids, such as omega-3s found in fish, directly support the ongoing structural development of the brain, boosting learning capacity and emotional regulation. 2. Preventing Chronic Disease The dietary patterns formed in youth act as a shield against chronic illness. A balanced diet rich in whole foods helps prevent: - High blood pressure and high cholesterol - Type 2 diabetes - Cardiovascular diseases and stroke - Certain types of cancer 3. Establishing Lifelong Habits Adolescence is a vital "window of opportunity". As teenagers gain autonomy, their food choices begin to stabilize into permanent routines. Prioritizing whole grains, lean proteins, fruits, and vegetables early makes individuals much more likely to continue these health-promoting habits throughout adulthood.

Vigorous activities (full of energy) will feel like your heart is beating much faster than normal and breathing is much harder than normal.
An example of a vigorous activity is jogging.
Children and young people (aged 2 to 18)
Children and adolescents should be active for at least 1 hour per day. This should be at a moderate to vigorous level.
Do strength exercises at least 3 days per week.
Adults (aged 18 to 64)
Adults are recommended to be active at moderate intensity for at least 2 hours and 30 minutes per week. Do strength activities on at least 2 days per week.
You can break this up into shorter bursts each day. For example, 3 times 10 minute bursts of activity.

Adults with disabilities
People with disabilities should be as active as they can for their level of ability. Aim to meet adult guidelines of at least 30 minutes of moderate-intensity activity on 5 days a week.
How to get started
Find an activity you can do every day. Take part in a team sport, attend classes at a leisure centre, or be more active in your daily routine. Try walking or cycling instead of travelling by car or public transport.
Build up your fitness
Start at your own pace and aim to build up to 30 minutes of activity 5 days per week. Improve your motivation by trying group activities or ask a friend to join you.
If you prefer to exercise alone, you can also track your activity and set yourself challenges.
Getting help
Talk with your GP if you have not exercised for a long time. You can also talk to them if you're worried about the effects of exercise on your health. Your GP can help you decide what type of activity will suit you, especially if you are taking any medicine.
