Nutrient Basics
Identify the six essential nutrients.
Carbohydrates, Proteins, Fats, Vitamins, Minerals, Water
What does GI stand for?
Glycaemic Index
Identify the Micronutrients for each function:
1. Which mineral helps transport oxygen around the body?
2. Which vitamin helps the body absorb calcium?
3. Which mineral is important for strong bones and teeth?
1. Iron
2. Vitamin D
3. Calcium
Identify the 5 dimensions of H/W
Social H/W
Physical H/W
Emotional H/W
Spiritual H/W
Mental H/W
Which lifespan stage occurs between 12–18 years?
Adolescence
Outline the difference between a macronutrient and a micronutrient?
Macronutrients are needed in large amounts; micronutrients are needed in small amounts.
Explain why protein is important during adolescence.
Supports growth, muscle development, and repair during periods of rapid physical development.
What is the function of Vitamin A and B12
Vitamin A: Maintain healthy vision and support an immune system.
Vitamin B12: Produce Healthy Red blood cells, synthesize DNA and maintain a functioning nervous System.
What are the three characteristic of emotional health?
Ability to 'identify' 'understand' and 'express' emotions
A child is learning to walk, say their first words, and begin to feed themselves independently.
Which lifespan stage is this most likely occurring in, and explain why these milestones are significant for development in this stage.
This is most likely the infancy stage (birth to 2 years).
These milestones are significant because infancy is a period of rapid physical, cognitive and emotional development. Learning to walk shows gross motor skill development, speaking first words shows language development, and feeding independently demonstrates increasing physical coordination and growing independence. These milestones indicate that the child is developing key foundations for later stages of development.
Which nutrient is the body's preferred source of energy? Why?
Carbohydrates - Readily avaliable in the body and can be stored in the liver
Compare the effects of a high GI breakfast and a low GI breakfast on energy levels.
High GI gives quick energy followed by a crash; low GI provides steady energy over a longer period.
Explain how insufficient Vitamin D intake can affect both physical health and one other dimension of health.
Vitamin D deficiency reduces calcium absorption, leading to weaker bones and increased risk of fractures (physical health). This may also reduce participation in physical and social activities, negatively affecting social or emotional wellbeing.
Explain how physical health can influence mental health.
Regular exercise can reduce stress and improve mood.
Name the three stages of prenatal development.
Germinal, embryonic and fetal
Explain why fibre is important for digestive health.
Fibre helps food move through the digestive system and reduces constipation
Explain why unsaturated fats are generally recommended over saturated fats.
Unsaturated fats can support heart health, whereas excessive saturated fat intake can increase cholesterol levels and cardiovascular disease risk.
Explain why iron deficiency is common in adolescents and how it affects energy levels.
Adolescents have increased iron needs due to growth and, in females, menstruation. Iron is needed for haemoglobin production, which transports oxygen. Low iron reduces oxygen delivery, causing fatigue and low energy.
A student experiences social isolation. Explain how this could affect two other dimensions of health.
Social isolation may negatively affect mental health (loneliness) and emotional health (reduced self-esteem).
Identify all 8 Life stages in order.
Prenatal, Infancy, early childhood, late childhood, adolescence, early adulthood, middle adulthood and late adulthood
Analyse how poor nutrient intake may affect three dimensions of health and wellbeing.
Poor nutrient intake may reduce physical health through fatigue, mental health through reduced concentration and social health through decreased participation in activities due to low energy levels.
Discuss impacts of high saturated fat and low protein intake.
High saturated fat increases cholesterol and heart disease risk; low protein reduces growth, muscle repair and may weaken physical health.
Analyse how a diet low in fruit and vegetables could affect both Vitamin C intake and overall health outcomes for a student.
Low fruit and vegetable intake reduces Vitamin C, weakening immune function and slowing wound healing. This may lead to more frequent illness, reduced school attendance, fatigue, and decreased participation in physical and social activities, negatively affecting overall health and wellbeing.
Analyse a sports injury affecting ones health and wellbeing. Refer to 3 dimensions in your response.
Physical injury reduces mobility; mental health affected through frustration/stress; emotional health affected through sadness and loss of identity or confidence.
Compare adolescence and older adulthood nutritional needs.
Adolescence requires more nutrients for growth; older adulthood requires fewer calories but more nutrients like calcium to maintain bone health.
