  • Changing Our Nutrient Needs.
    • Age
      • Children need a lot of energy and nutrients to support their rapid growth
        • Calcium and vitamin D are important as tooth and bone development occurs during childhood
        • High energy foods rich in protein, iron and vitamin A are also important
      • Teenagers grow rapidly so they need more protein and energy to support this. (Especially boys)
        • Iron is important for growth, muscle development and menstruation.
      • Adults should eat a balanced diet, with moderate amounts of meat and alcohol.
        • The amounts of saturated fats and sugars should be limited to reduce the risk of obesity and the development of type 2 diabetes
      • Older adults generally require less energy but still recommended that they have a balanced diet
        • Vitamin D and calcium may help reduce the risk of osteoporosis and arthiritis
    • Athletes have extra nutritional needs because they use more energy, vitamins, minerals and water than non-athletes.
      • Get most of their energy from carbs, so a starch-rich diet is recommended
      • Need protein for muscle build.
      • Water is important because dehydration can cause fatigue and muscle cramp.
    • Diabetics have to monitor their blood sugar levels frequiently.
      • If a diabetic eats to much carbs their blood sugar level can become to high and cause serious problems.
      • A healthy diet and taking regular meals can help a diabetic maintain normal blood sugar levels.
