Study Notes
Human Diet and Nutrition
- A person's diet consists of six types of nutrients: vitamins, carbohydrates, minerals, proteins, water, and fats.
- A diet should also contain fibre (roughage), which is not a nutrient but helps with digestion.
Balanced Diet
- A balanced diet contains all the required nutrients in suitable proportions and the right amount of energy.
- A diet that lacks essential nutrients can lead to health problems.
Energy Needs
- The energy a person uses daily depends on age, sex, and occupation.
- Energy comes from the food we eat, and excess energy is stored as fat.
- If we eat too little, we may not have enough energy, leading to fatigue.
Energy Content of Food
- One gram of protein or carbohydrate contains a certain amount of energy.
- One gram of fat contains about twice as much energy as one gram of protein or carbohydrate.
Dietary Changes at Different Life Stages
- Pregnant women need to eat more and ensure they have extra calcium and iron for their baby's development.
- Breastfeeding women need to eat more to support milk production.
- People need to eat less as they reach their 50s and 60s due to slower metabolism.
Importance of Nutrients
- Nutrients provide energy and support overall health.
- A diet lacking essential nutrients can lead to health problems.
- Carbohydrates, fat, and protein are essential for energy and overall health.
- Vitamins, minerals, fibre, and water are also essential for proper bodily functions.
