immediate sources of energy
carbohydrates, especially in their natural form and is not refined, have a high nutritional content and are our most immediate source of energy. Should be taken in large quantities, especially by those who carry out activities involving significant physical effort.
The body converts carbohydrates into simple glucose, the form of sugar used by cells throughout the body. Glucose can be used immediately to provide energy or stored for a short time in the muscles or the liver as glycogen or starch, whose molecules contain branched chains of glucose, which, if kept for too long and the excess is converted and stored as fat.
carbohydrate molecules contain only carbon, hydrogen and oxygen, including sugars and starches. Sugar cane and refined sugar from beet is our main source of carbohydrates simple and rapid use an important source of energy. It consists mostly sucrose and is the sweetest natural carbohydrates in our diet.
Refined sugar is not easily give that feeling of satiety feature of other foods based on carbohydrates, so we tend to take greater quantities, at the risk of turning it into fat reserves, may also cause damage to teeth. We should take sugar and honey (and this is particularly true for sugar) only in small quantities in each meal, so as to allow a slower absorption.
molecules of starch include chains of glucose molecules that the body must break through the digestive juices before they can absorb. Although the trial has begun in the mouth, most of it happens in the gut, so that the starch-based foods also cause damage to the teeth smaller than those containing sugar. Starches also compared with sugary foods contain more vitamins, fiber and minerals, and are thus more comprehensive.
Insulin, a hormone produced in the pancreas, is necessary for the oxidation of glucose, ie the process that provides the energy needed by the body. Where insulin is produced in sufficient quantities can cause the onset of diabetes.
honey and many fruits such as figs (and some vegetables, including carrots and beets) contain a sugar called fructose, also known as fruit sugar. The metabolism of fructose does not require insulin directly, so that sugar is particularly suitable for people with diabetes. These foods also contain other substances of high nutritive value.
Starches should represent the most significant amount of daily carbohydrate intake. The best sources are derived from wheat, oats, rice, corn and other cereals, as well as beans, peas and potatoes. As has been repeatedly pointed out that the bread is good, one might conclude that the white bread hurt. In fact, the white bread is a healthy food, but the whole is more complete. More balanced diet, we eat a greater quantity of products such as bread and pasta, and decrease in proportion to the amount of red meat, fat and sugar refined.
cakes, biscuits and puddings made with white sugar and flour do not cause damage, but should not become part of a regular diet. These foods are usually high in fat, and eating them, we introduce too many calories. Sostituitoli with vegetables or fresh fruit when you feel the need for a snack. Many recipes have the same success if made with whole wheat flour instead of white with fresh or dried fruit to sweeten instead of sugar.
