Answer:
Nutrition is the science of food and its relationship to health – how the human body uses food and processes the nutrients it contains to enable the body to perform functions (i.e. the heart to beat, the lungs to breathe, the kidneys to filter blood, the brain to think etc.).
Encompassed in this definition is how much energy (kilojoules) a body needs to maintain a healthy weight. Energy is delivered to the body through foods. Any energy consumed (in the form of carbohydrates, protein or fat) and not used for metabolism, growth or physical activity will be stored as body fat. There are many factors that dictate how much energy a person needs, but in simple terms the more the body moves, the greater the amount of energy will be needed.
The kilojoule is the measure of energy used in Australia. It is the International unit for energy, but some countries (e.g. USA) still use the calorie.
The conversion is: 4.2kJ = 1 calorie. We use it to determine how much energy a food will provide when we eat it.
The nutrients that provide energy are commonly referred to as macronutrients (carbohydrates, lipids, and proteins). Carbohydrates and proteins provide a similar amount of energy per gram of food. Lipids are a concentrated source of energy and provide almost twice the amount of energy than that supplied by proteins and carbohydrates.
For your information only:
CHOs = 16 kJ per gram of CHO
Protein = 17 kJ per gram of protein
Lipids = 37 kJ per gram of lipid
Children aged between 4-18 years require ~6500 to 14000 kJ per day. The approximate number of kilojoules a child consumes per day will depend on their age and physical activity level. The values given are for average physical activity only. For further information, please refer to the
Explanation:
kj means kilo joules
Answer:
1. There are seven main classes of nutrients that the body needs. These are carbohydrates, proteins, fats, vitamins, minerals, fibre and water. It is important that everyone consumes these seven nutrients on a daily basis to help them build their bodies and maintain their health.
2.Macros are macronutrients. Your body needs these nutrients in larger amounts in order to function properly as macro means large. In addition, all of these nutrients provide your body with energy measured in the form of calories or kcals. There are three types of macronutrients: carbohydrates, proteins, and fats.
3. Micronutrients are essential elements needed by life in small quantities. They include microminerals and Vitamins. Microminerals or trace elements include at least iron, cobalt, chromium, copper, iodine, manganese, selenium, zinc, and molybdenum.
4. Vitamins and minerals are two of the main types of nutrients that your body needs to survive and stay healthy. Vitamins help your body grow and work the way it should. There are 13 vitamins—vitamins A, C, D, E, K, and the B vitamins
5. A vitamin is an organic molecule that is an essential micronutrient which an organism needs in small quantities for the proper functioning of its metabolism. Essential nutrients cannot be synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the diet
6.A vitamin that can dissolve in water. Water-soluble vitamins are carried to the body's tissues but are not stored in the body. They are found in plant and animal foods or dietary supplements and must be taken in daily. Vitamin C and members of the vitamin B complex are water-soluble.
7.In rare cases in the United States or in other parts of the world where nutritional diets may vary, vitamin A deficiency can also lead to night blindness. Vitamin A, also called retinol, plays a role in transforming nerve impulses into images in the retina. The retina is a light-sensitive area in the back of your eye.
8. Both vitamin K-1 and vitamin K-2 produce proteins that help the blood to clot. Blood clotting or coagulation prevents excessive bleeding internally and externally. While vitamin K deficiency is rare, it means a person's body cannot produce enough of these proteins, increasing the risk of excessive bleeding.
9. Thiamine, folate, biotin, riboflavin, and panthothenic acid are water-soluble vitamins that are plentiful in the diet, but that are also synthesized by gut bacteria. Likewise, it has been estimated that up to half of the daily Vitamin K requirement is provided by gut bacteria
10. Vitamin B1
A deficiency can cause weakness, fatigue, nerve damage, and psychosis. When the deficiency becomes severe, it causes a disease known as beriberi. There are many foods that provide thiamin so it's easy to get enough from your diet.
