Answer:
There are 6 essential nutrients that the body needs to function properly. Nutrients are compounds in foods essential to life and health, providing us with energy, the building blocks for repair and growth and substances necessary to regulate chemical processes.
There are six major nutrients: Carbohydrates (CHO), Lipids (fats), Proteins, Vitamins, Minerals, Water.
Explanation:
Proteins: meat, dairy, legumes, nuts, seafood and eggs
Carbohydrates: pasta, rice, cereals, breads, potatoes, milk, fruit, sugar
Lipids (most commonly called fats): oils, butter, margarine, nuts, seeds, avocados and olives, meat and seafood
Vitamins: common vitamins include the water soluble B group vitamins and vitamin C and the fat soluble vitamins A, D, E and K
Fruits and vegetables are generally good sources of Vitamin C and A and folic acid (a B group vitamin)
Grains and cereals are generally good sources of the B group vitamins and fibre
Full-fat dairy and egg yolks are generally sources of the fat soluble vitamins A, D and E
Milk and vegetable or soya bean oil are generally good sources of vitamin K, which can also be synthesised by gut bacteria
Minerals: (sodium, calcium, iron, iodine, magnesium, etc.): all foods contain some form of minerals.
Milk and dairy products are a good source of calcium and magnesium
Red meat is a good source of iron and zinc
Seafood and vegetables (depending on the soil in which they are produced) are generally good sources of iodine
Water: As a beverage and a component of many foods, especially vegetables and fruits.
Answer:
Nutrients That Build and Maintain Body Cells
- Water
- Vitamins
- Mineral Elements
- Carbohydrates, including fiber
Nutrients That Provide Energy
- Fats
- Carbohydrates (starches and sugars)
- Proteins
Fats
- Fats should make up a very small percentage of your whole diet, 15 percent or less. But nevertheless fats are needed, and you should not eat a fat-free diet, rather eat a low fat diet. Avoid saturated fats like they were cancer (because these are the fats that are attributed to causing cancer and cardiovascular disease). The best fats are plant based uncooked oils (olive, canola, safflower and flaxseed).
Carbohydrate
As an athlete, carbohydrates are the major nutrients that give you energy. Everything you do in life requires a certain amount of carbohydrates, sleeping, studying, breathing, and training. Athletes who truly desire to become the top dog will stop at nothing to get the most out of the foods they consume and thus make wise choices as to what type of carbohydrates they eat.
Proteins
Proteins received their name from the Greek and mean "to take first place." As nutrients, they actively build living nitrogenous tissue, they are the building blocks for all human tissue; if you do not eat them, you do not recover and rebuild after tough workouts. Plain and simple. However this does not mean the more you eat the more you rebuild/grow. Balance is the key to proper sports nutrition. Your body can only assimilate and absorb between 30-40 grams of quality protein per meal. If you consume more protein, or any macronutrient, than your body can use, it will place unnecessary strain on your digestive system as well as end up being stored as excess energy/fat. For protein to work properly it must be complete, all the essential amino acids must be present.
