Nutrition involves understanding how diet impacts health and disease. It is the process by which the body takes in and uses nutrients from food, including macronutrients like proteins, carbohydrates, and fats, and micronutrients like vitamins and minerals. These nutrients support growth, energy, immune function and more. A balanced diet containing a variety of whole foods is important for meeting nutritional needs, especially during periods of growth like adolescence. While vitamins and minerals are essential in small amounts, consuming supplements in large concentrated doses can be harmful.

2. NUTRITION

4. Is the science that studies the process by which living organisms acquire all the things that are necessary for them to live and grow.

5. Is commonly seen as a combination of basic requirements such as food and water.

7. The study of nutrition is able to identify how certain illnesses and conditions may be triggered by poor diet, metabolic diseases, food allergies, and other dietary factors. When you ask any health experts, whether he be a doctor, dentist, or psychologist, to name a branch of medicine that is completely unrelated to nutrition, they will most probably be dumbfounded, since there is no answer at all. Nutrition is present in all aspects of life. Form the moment of fertilization, right at that time a sperm cell fertilizes an egg, until a fetus develops, to its birth, to its maturity and death, some form of nourishment always takes places. Even at death, the body serves as nourishment for several other organisms. Anything that has life and carries out, and all various chemical and biochemical activities, will rely on nutrition to survive – because all of us depend on energy to live and energy results from food combustion.

13. minerals

14. waterThey are needed in large amount of nutrients. They are needed in small amount to sustain our normal health and body functions. Having good nutrition means eating the right types of foods in the right amounts so you get important nutrients. There are no special diets, or particular foods, that will boost your immune system. But there are things you can do to keep your immunity up.

16. Fats gives you extra energy.

17. Proteins builds muscles and a strong immune system.

18. Water gives cells shape and acts as a medium where body processes can occur.

19. Vitamins regulate body processes.

21. Two categories of vitamins LIFESTYLE

22. Fat-soluble> dissolve in fat and can be stored in your body. vitamins A, D, E, and K Vitamin Aprevents eye problems, promotes a healthy immune system, it is essential for the growth and development of cells, and keeps skin healthy. Vitamin Dstrengthens bones because it helps the body absorb bone-building calcium. Vitamin Eis an antioxidant and helps protect cells from damage. It is also important for the health of red blood cells. Vitamin KNaturally produced by the bacteria in the intestines, vitamin K plays an essential role in normal blood clotting and helps promote bone health.

23. 2. Water-soluble> need to dissolve in water before your body can absorb them. vitamins C and B complex VitaminCis needed to form collagen, a tissue that helps to hold cells together. It's essential for healthy bones, teeth, gums, and blood vessels. It helps the body absorb iron and calcium, aids in wound healing, and contributes to brain function. vitaminBare a group of water-soluble vitamins that play important roles in cell metabolism. B complex: Vitamin B1 (thiamine)helps the body convert carbohydrates into energy and is necessary for the heart, muscles, and nervous system to function properly. Vitamin B2 (riboflavin) is essential for turning carbohydrates into energy and producing red blood cells. It is also important for vision. Vitamin B3 (niacin or niacinamide) helps the body turn food into energy. It helps maintain healthy skin and is important for nerve function. Vitamin B5 (pantothenic acid) is the amide between pantoate and beta-alanine Vitamin B6 (pyridoxine) is important for normal brain and nerve function. It also helps the body break down proteins and make red blood cells. Vitamin B7 (biotin) is composed of a ureido (tetrahydroimidizalone) ring fused with a tetrahydrothiophene ring. Vitamin B9(folic acid) helps the body make red blood cells. It is also needed to make DNA. Vitamin B12 (cobalamins) helps to make red blood cells, and is important for nerve cell function.

25. 1. Major minerals (macro minerals) >Large amount of minerals -> Calcium, Iron, Magnesium, Phosphorus, Potassium, and Sodium Calcium (Ca)Key constituent of bones and teeth; Essential for vital metabolic processes such as nerve function, muscle contraction, and blood clotting. Iron (Fe) Essential for transfer of oxygen between tissues in the body; Magnesium (Mg)Essential for healthy bones; Functioning of muscle & nervous tissue;Needed for functioning of approx. 90 enzymes. Phosphorous (P)Constituent of bone tissue; Forms compounds needed for energy conversion reactions (e.g. adenosine triphosphate - ATP). Potassium (K)Main base ion of intracellular fluid; Necessary to maintain electrical potentials of the nervous system - and so functioning of muscle and nerve tissues. Sodium (Na) Controls the volume of extracellular fluid in the body; Maintains the acid-alkali (pH) balance in the body; Necessary to maintain electrical potentials of the nervous system - and so functioning of muscle and nerve tissues.

26. 2. Trace minerals (micro minerals) >Small amount of minerals -> Chromium, Copper, Manganese, Selenium, Sulphur, Zinc, Iodine, Boron, Germanium, Selenium, Silicon, Vanadium, and Molybdenum Chromium (Cr)Involved in the functioning of skeletal muscle. Copper (Cu) Part of the enzyme copper-zince superoxide dismutase (CuZn SOD); Also present in other enzymes, including cytochrome oxidase, ascorbic acid oxidase, and tyrosinases; Found in the red blood cells, and in blood plasma. Manganese (Mn) Antioxidant properties; Fertility; Formation of strong healthy bones, nerves, and muscles; Forms part of the enzyme copper-zince superoxide dismutase (CuZn SOD) system. Selenium (Se) Antioxidant properties (prevents peroxidation of lipids in the cells); Essential component of the enzyme glutathione peroxidase; Contributes to efficiency of the immune system - very wide variety of protective functions within the body. Sulphur (S)Healing build-up of toxic substances in the body; Structural health of the body (sulphur is a part of many amino acids incl. cysteine and methionine); Healthy s kin, nails & hair.

27. f. Zinc (Zn) Needed for: Functioning of many (over 200) enzymes; Strong A immune system. g. Iodine ( I )helps to metabolize excess fat and is necessary for thyroid gland health. h. Boron (B) is needed for healthy bones, muscle growth, and cognitive function. i.Germanium (Ge) Germanium enhances cellular oxygenation, which in turn improves total body health. It is found in basically all organic food, with high amounts in shiitake mushrooms, broccoli, celery, milk, and rhubarb. j. Selenium (Se) This mineral works synergistically with vitamin E to protect free radical damage to fatty material. k. Vanadium (V) Used for cellular metabolism, bone and teeth formation, and growth, vanadium is another micro mineral that athletes may need more of. l. Molybdenum (Mo) An integral nutrient for the conversion of purines to uric acid and nitrogen metabolism, as well as bone and teeth health, deficiencies of this micro mineral are linked to mouth and gum problems as well as cancer.
