      Lesson details

      Learning outcome

      I can explain the importance of a balanced diet and how it supports overall health and performance.

      Key learning points

      1. A balanced diet includes a variety of foods to provide essential nutrients, vitamins and minerals.
      2. No single food item provides all the necessary nutrients, so diversity in food choices is crucial.
      3. Calorie requirements are dependent on activity levels and the length and intensity of the activity.
      4. Athletes may need to eat more of a specific nutrient to meet their needs., e.g. weightlifters and protein.

      Keywords

      • Balanced diet - it is defined as eating: the right amount (of calories) for energy expended; according to how much you exercise; different food types to provide suitable nutrients, vitamins and minerals

      • Carbohydrate - the body's preferred energy source

      • Protein - essential for the growth and repair of muscle tissue

      • Energy - the ability to perform activities and sustain effort

      Common misconception

      There are many misconceptions about diet, such as, the need to cut out carbohydrates or fat because they are seen as responsible for weight gain.

      A balanced diet requires all nutrients because each has its own benefits to the body and health. Cutting any of them out completely will negatively impact overall health and performance in sport and physical activity.

      Teacher tip

      A complementary activity for this lesson is for pupils to input the food they ate the previous day into an online nutrition calculator and reflect on the results.
