Overview of Nutrition and Health |
Overview of Nutrition and Health - Nutrition studied the eating process, absorption and using nutrients needed by the body for growth, development and upkeep of life.
Nutrients are chemicals in food that nourish one's body.
Various nutrients can be done in your body. Nutrients that can 't be manufactured in our bodies, called essential nutrients, have to be consumed from the diet. Overview of Nutrition and Health
Important nourishment are:
# Proteins (in proteins)
# Certain fats (fat and oil)
# Nutritional supplements.
9 of 20 proteins from the protein are crucial nutrients.
If essential nutrients are certainly not for sale in sufficient quantities, can happen nutrient deficiency disease.
To discover whether you were getting enough nutrients, necessary:
- Info on diet plan
- Physical examination to assess the composition (quantity of fat and muscles) plus the function from the body
- Other laboratory tests to measure the content of nutrients from the blood and tissues.
Broadly speaking, the nutrients are divided into 2 varieties of macronutrients and micronutrients.
Macronutrients, which consists of proteins, fats, carbohydrates and many minerals, your whole body needs daily in good sized quantities. Macronutrients is a major part of the diet and offer the power necessary for growth, maintenance and activities on the body.
Micronutrients are expected in a small amount (milligrams to micrograms). Which remain in the micronutrients are vitamins and certain minerals that cause chemical alterations in using macronutrients.
Other food components which are useful, not digested or metabolized. Are especially component is often a fiber (cellulose, pectin) and sap.
Experts recommend to take no less than 20 grams of fiber / day for:
- Facilitate this function
- Reduces glucose levels and cholesterol changes after eating
- Increasing expenditure cancer-causing substances made by bacteria inside large intestine.
Macronutrients
Organic macronutrients.
Organic macronutrients are carbohydrates, fats and proteins, which constitute 90% on the dry weight of food and 100% energy.
Macronutrients digested inside the intestine and is separated into basic forms, namely:
- Sugar from carbohydrates
- Efas and glycerol from fats
- Amino acids in the protein.
Energy is made up of:
- 4 calories in 1 gram of protein or carbohydrate
- 9 calories in 1 gram of fat.
Energy requirements changes from 1000-4000 calories / day dependant upon age, gender and exercising:
1. Girls that don't move, small children and older adults need about 1600 calories / day
2. Children that are older, active women and men who will be not active needs about 2000 calories / day
3. Teenage boys and active young adult men need about 2400 calories / day.
The composition with the calories are listed below:
- 55% emanates from carbohydrates
- 30% are from fat
- 15% are from protein.
When energy intake seriously isn't according to the requirements of your body, weight reduction will occur. Fat reserves within the body are going to be utilized to meet the energy needs required. In additional severe circumstances, the body will use protein as a possible energy source.
Fat
Approximately 7% of fat consumed within the diet, a vital fatty acid (3% of total calories or approximately 8 grams), and incorporated into macronutrients.
Essential fatty acids consist of:
- Linoleic acid
- Linolenic acid
- Arachidonic acid
- Acid eikosapentanoat
- Dokosaheksanoat acid.
Linolic acid and linolenic acid present in vegetable oils.
Dokosaheksanoat eikosapentanoat acid and acid, which can be needed for brain development, within fish-liver oil.
By the body processes, arachidonic acid can be formed from linolic acid; eikosapentanoat acid and dokosaheksanoat acid may be formed from linolenic acid.
Makromineral
Which remain in the makromineral is:
- Calcium
- Phosphate
- Sodium
- Chloride
- Potassium
- Magnesium.
They belong the macronutrients as needed with the body in big amounts (about 1-2 grams / day).
Water is also contained in macronutrients, since it takes 1 milliliter / calories / day for each and every with the energy used (2 liters / day).
Micronutrient
Certain health supplements a part of micronutrients.
Vitamin is made up of two categories, namely:
- Fat-soluble vitamins (vitamins A, D, E, K)
- Water-soluble vitamins (ascorbic acid and 8 sorts of b vitamin complex).
Essential Minerals
Which are part of the essential minerals are iron, zinc, manganese, molybdenum, copper, selenium, iodide and fluoride.
Except fluoride, lots of minerals to operate activates the enzymes necessary for metabolism.
Fluoride and calcium elements forming an ingredient that assists stabilize the mineral in bones and teeth, and prevents cavities.
Other minerals, such as arsenic, chromium, cobalt, nickel, silicon and vanadium, which could greatly necessary for animals, not needed by humans.
All minerals are toxic when consumed wholesale, and many minerals (arsenic, nickel, chromium) has become labeled as the main cause kanker.Kecuali fluoride, a myriad of minerals to work activates the enzymes required for metabolism.
Fluoride and calcium elements forming a compound which enables you stabilize the mineral in bones and teeth, and prevents cavities.
Other minerals, such as arsenic, chromium, cobalt, nickel, silicon and vanadium, that might greatly essential for animals, not needed by humans.
All minerals are toxic when consumed large quantities, and some minerals (arsenic, nickel, chromium) may be identified as a contributing factor to cancer.
NUTRITIONAL NEEDS
The aim of the best foods is usually to achieve and maintain body composition and mental and physical strength are fantastic.
Needs essential nutrients daily depending on age, sex, weight, height and training, and metabolism.
U.S. Department of Agriculture has proposed four basic daily food groups, namely:
- Milk and milk products
- Meat and vegetables full of protein
- Wheat and bread
- Fruit and veggies,
to be a balanced diet guide.
The following information is supposed to help people choose foods that incorporate important nourishment and also have a small risk from the occurrence of certain diseases, for example cancer, blood pressure, heart disease and stroke.
In this particular slowly move the amount that must definitely be provided everyday, for every style of food, different. It depends for the energy required, between 1600 - 2400kalori/hari.
Generally, reduced fat consumption to 30% from the calories and utilization of fruits, vegetables and grains, should be improved.
