Transcript of Essential Nutrients

By: Monica, Shannon and Nikola

Your body uses proteins in your diet to build new cells, maintain tissues, and synthesize new proteins that make it possible for you to perform basic daily functions. Protein is an essential nutrient found in animal products, nuts, and beans.
The human body is chock-full of proteins. They are present in the outer and inner membranes of every living cell. protein makes an appearance in many body parts, such as: hair, nails, and the outer layers of your skin .Muscle tissue contains proteins, bones have plenty of protein as well, red blood cells, white blood cells ...etc... All proteins are made up of 20 different combinations called amino acids. Daily base of protein needed is 55g for men and 45g for women.

Carbohydrates in foods contain starch and glucose to produce energy for the organism.The body prefers glucose for the brain, central nervous system and red blood cells to function. The Institute of Medicine's Dietary Reference Intakes for Macronutrients list the food groups consisting of grains, vegetables and fruits as sources of carbohydrates. Carbohydrate food molecules are made up of carbon, hydrogen and oxygen. Each gram of carbohydrate has four calories.
There are 7 essential Nutrients:
- Water
- Protein
- Carbs
- Fats
- Minerals
- Vitamins
- Fiber

So, what exactly are vitamins? Vitamins are organic compounds wich are needed in small amounts. We mostly get our vitamins from food, because our body does not produce enough of the vitamins, or none at all. Sometimes the compound is a vitamin for a human but not for some other kind of animal. For example, vitamins c is for humans but not for dogs, because dogs can produce enouph for their own needs, while humans cant.

So, vitamin is both an
organic compound and an
essential nutrient that the body
cannot produce enouph on its own.

The body uses fat as a fuel source, and fat is the major storage form of energy in the body. Fat also has many other important functions in the body, and a moderate amount is needed in the diet for good health. Too much fat or too much of the wrong type of fat can be unhealthy. Some examples of foods that contain fats are butter, oil, nuts, chocolate and some dairy products.

oligosaccharides, starch polysaccharides and non-starch polysaccharides. If you do not have enough
fiber in your body you may suffer from constipation, irritable bowel syndrome, diverticulitis, heart
disease and some cancers.
Water is a liquid. It keeps you hydrated so you have to drink it a lot. The average person should drink
