2022-11-11 20:22:09 How many and what food do we need?

Age, sex, weight, height, and level of activity determine the number of calories a person needs each day. The recommended daily caloric intake for a child aged 11 to 14 can range from 1,600 to 2,600 calories per day. For adults, this can range from 1,800 to about 3,000.

A healthy diet contains a balanced mix of different foods that together provide all essential nutrients.

A food pyramid is a diagram of a healthy diet that shows the number of servings of each food group a person should eat every day.

Malnutrition is the lack of a balanced diet. Too few or too many nutrients, or an imbalance of nutrients (too many carbohydrates, for instance, and not enough fruits and vegetables) can lead to malnutrition.

Undernutrition is a form of malnutrition. Usually linked to hunger, it happens when the body does not get enough food to meet its needs. It can cause many diseases and even lead to death, which is called starvation in this context.

2022-11-07 20:11:02 What are functions of B vitamins and of two vitamin-like nutrients?

Vitamin B6 is also called pyridoxine. Vitamin B6 helps form red blood cells and maintain brain function. This vitamin also plays an important role in the proteins that are part of many chemical reactions in the body. The more protein you eat the more pyridoxine your body requires.

Vitamin B12, like the other B vitamins, is important for metabolism. It also helps form red blood cells and maintain the central nervous system.

Biotin (B7) is essential for the metabolism of proteins and carbohydrates, and in the production of hormones and cholesterol.

Niacin (B3) is a vitamin that helps maintain healthy skin and nerves. It also has cholesterol-lowering effects at higher doses.

Folate (B9) works with vitamin B12 to help form red blood cells. It is needed for the production of DNA, which controls tissue growth and cell function. Any woman who is pregnant should be sure to get enough folate. Low levels of folate are linked to birth defects such as spina bifida. Many foods are now fortified with folate in the form of folic acid.

Pantothenic acid (B5) is essential for the metabolism of food. It also plays a role in the production of hormones and cholesterol.

Riboflavin (B2) works with the other B vitamins. It is important for body growth and the production of red blood cells.

Thiamine (B1) helps the body cells change carbohydrates into energy. Getting enough carbohydrates is very important during pregnancy and breastfeeding. It is also essential for heart function and healthy nerve cells.

Some vitamin-like nutrients are also needed by the body such as:
Choline that helps in normal functioning of the brain and nervous system. Lack of choline can cause swelling in liver.
Carnitine that helps the body to change fatty acids into energy.

2022-11-06 20:02:04 What are functions of vitamins A, C, D, E, K?

Vitamin A helps form and maintain healthy teeth, bones, soft tissue, mucous membranes, and skin.

Vitamin C, also called ascorbic acid, is an antioxidant that promotes healthy teeth and gums. It helps the body absorb iron, maintain healthy tissue and heal wounds.

Vitamin D is also known as the "sunshine vitamin”. 10-15 minutes of sunshine 3 times a week is enough to produce the body's requirement of vitamin D for most people. It helps the body absorb calcium that we need for the normal development and maintenance of healthy teeth and bones, and maintain proper blood levels of calcium and phosphorus. Without sunshine, it is rather hard to get enough vitamin D from food sources.

Vitamin E is an antioxidant also known as tocopherol. It helps the body form red blood cells and use vitamin K.

Vitamin K is needed because without it, blood would not stick together. Some studies suggest that it is important for bone health.

2022-11-05 19:16:11 What are vitamins?

Vitamins are micronutrients that help the body make full use of other nutrients by assisting the chemical reactions that make those nutrients work. They are needed for normal cell function, growth, and development.

There are essential vitamins:
Vitamin A
Vitamin C
Vitamin D
Vitamin E
Vitamin K
Vitamin B1 (thiamine)
Vitamin B2 (riboflavin)
Vitamin B3 (niacin)
Vitamin B6 (pyridoxine)
Vitamin B12 (cyanocobalamin)
Pantothenic acid (B5)
Biotin (B7)
Folate (folic acid or B9)

Vitamins are grouped into categories:
The four fat-soluble vitamins - A, D, E, and K – are stored in the body's liver, fatty tissue, and muscles. They are absorbed more easily by the body in the presence of dietary fat.
The nine water-soluble vitamins – C and all the B vitamins – are not stored in the body and should be consumed on a regular basis. The exception to this is vitamin B12, which can be stored in the liver for many years.

2022-11-02 20:15:40 What are food, calories and nutrients?

Food is one of the basic necessities of life, it is any substance consumed to provide nutritional support for an organism.

Food contains nutrients, which are essential for the growth, repair, and maintenance of body tissues and for the regulation of vital processes. Nutrients provide the energy our bodies need to function.

A food staple is a food that makes up the dominant part of a population's diet. It varies from place to place, depending on the food sources available, is eaten regularly—even daily—and ideally should supply a major proportion of a person's energy and nutritional needs.

The energy in food is measured in units called calories.

Scientists divide nutrients into major groups:
carbohydrates
fats
proteins
minerals
vitamins
water.
Most foods contain all or most nutrient groups, in different amounts.
