1. Define what is meant by the term ‘healthy diet’.A healthy diet is likely to include a large number or variety of foods, from each of the food groups, as this allows us to get all the nutrients that we need.
2. Describe why the healthy diets of adults and children may be different. Provide at least three examples of these differences. Older children often have higher nutrient requirements than adults in order for them to grow properly, 15-to-18 year-old boys need more B vitamins, calcium, phosphorus and iron than adult men

4. Name three sources of energy in food. Then, identify the amount of energy that 1g of each source provides.
Proteins – essential to growth and repair of muscle and other body tissues -1 gram = 4 calories Fats – one source of energy and important in relation to fat soluble vitamins- 1 gram = 9 calories Carbohydrates – our main source of energy -1 gram = 4 calories
5. Based on your own diet and lifestyle…
• Estimate your own Basal Metabolic Rate (BMR)• Estimate your own Physical Activity Level (PAL)• Based on these BMR and PAL values, what is your total energy requirement?
Basal Metabolic Rate=1681.59
Physical Activity Level
140lbs x 17 = 2380
1681.59×1.41=2371Energy requirement – could work hard with the amount of energy im taking in
6. Identify at least two factors that can affect a person’s energy requirements.
• Age• Gender
7. For a person you know who wishes to manage their weight, outline the relationship between their energy intake and energy expenditure and the impact this can have on their weight.
If you don’t eat loads off food and have loads off excise you will be under weight If you eat loads off food and don’t do much excise you will be over weight If you do equal amounts off both you will be the right weight

• In the first column, list the six key nutrients needed by the body. • In the second column, describe the foods that can provide each nutrient. • In the final column, describe the impact that each nutrient can have on your health (either positive or negative).
|Key nutrients |Food sources |Health impact | |1. protein |Meat, Eggs and dairy |Positive but can be negative if have to much | | | | | |2. carbohydrates |Pasta, rise, potatoes |To much can causes obesity | | | | | |3. fat |Dariy products,biscults and cakes |If you eat to much you will become fat. | | | | | |4. vitamins |Green veg, oranges |richsources of calcium, magnesium, | | | |potassium, iron, beta-carotene, vitamin | | | |B-complex, vitamin-C, vitamin A, and vitamin | | | |K | |5. calcium |Milk, yogurt, hard cheeses, fortified |Essential for bone growth and strength, blood| | |cereals, spinach |clotting, muscle contraction | |6. water |Any liquid drink |You need to drink so you don’t dehydrate | | | | |
