Nutrition Encyclopedia - Accordion
Nutrients are the compounds in foods that sustain all of your body processes: they give you energy, allow you to grow and help to regulate all of your body processes. There six major classes of essential nutrients grouped together based on similarities in function. : carbohydrate, protein, fats, vitamins, minerals, and water. There are also other types of nutrients that are non-essential, such as chlorophyll and anti-oxidant, which help your body to achieve optimum health.
- CARBOHYDRATE
- carbohydrates are converted into glucose that are either used directly to provide energy for the body, or stored in the liver for future use.
- glucose from carbohydrate is needed by some cell tissues in the brain to prevent the reduction of brain function
- prevents the body from breaking down muscle tissue for fuel due to the lack of sufficient carbohydrate energy.

Sources:
- Purified water has been processed usually by procedures that remove minerals and contaminants. The 2 most used methods are reverse osmosis and distillation. Reverse osmosis forces water through a filtering membrane. The pores in the membrane are small enough to filter out most of the dissolved minerals, but not all. Distillation boils water and the condensed steam is collected. Distilled water leaves most of the non-volatile components behind and therefore, has less minerals than reverse osmosis. Drinking too much of de-mineralized water can lead to increase mineral deficiencies and an acid state.
- Spring water comes from an underground formation and must flow naturally to the earth's surface. Spring water is typically protected from microorganisms sometimes found in surface water. Bottled spring water is collected at the spring or through a hole that taps the source, and the source must be stated on the label.
- Mineral water originates from a geologically and physically protected underground water source, a mineral spring, containing various minerals such as salts and sulfur compounds. These minerals must occur naturally and bottled mineral water should be bottled at the source. Mineral water comes in sparkling or still. Minerals are essential for the optimum growth and health of the body, and mineral content of water can be easily absorbed by the body as compared to mineral content of the food.
- ANTIOXIDANTS
Free radicals are molecules produced when your body breaks down food, or by environmental exposures, such as tobacco smoke and radiation.
Benefits:
- protect the body from heart disease and cancer
- maintains cells to slow down the aging process
Deficiency: a general lack of anti-oxidants means that the body cannot protect itself against oxidation, which can cause or assist Alzheimer's disease. Cancer, cardiovascular disease, cataracts, diabetes, hypertension, infertility, macular degeneration (eye lens degeneration), measles, mental illnesses, periodontal disease, respiratory tract infection as well as rheumatoid arthritis.
Sources: blueberries, tomatoes, pomegranate, and black rice.
