What is glucose?

Glucose is a simple sugar that provides the body with a primary energy source. This type of sugar comes from the digestion of carbohydrates into a chemical that the body can easily convert to energy. If glucose levels in the bloodstream are not properly regulated, a person can develop a serious condition such as diabetes.

from carbohydrates

people gain most of their glucose from digestion of sugar and starch in carbohydrates. Foods such as rice, pasta, grain, potatoes and processed sweets contain carbohydrates that can be converted into glucose. The digestive system of the body by bile and enzymes decomposes starch and sugar into glucose in these foods. This functional form of energy is then absorbed by the small intestine into the bloodstream. It then carries all over the body and provides energy to perform all types of activities such as simple movements, requiring physical exercise or even thinking.

glycemic index

food can be evaluated according to the glycemic index, indicating how fastE are carbohydrates decomposed by the body and glucose is released into the bloodstream. White bread and most breakfast cereals have a high glycemic index, which means that carbohydrates decompose and blood sugar levels increase faster. Most fruits, vegetables and nuts have low glycemic indices. Wholemeal products and some types of potatoes have in the middle of glycemic indices.

regulatory levels

Glucose is such a vital source of energy and interacts with the digestive and endocrine system in the body, so maintaining its levels-called blood sugar levels to the normal range is extremely important to human health. The human body has adapted to maintain this ideal level by storing extra glucose in the vjatra and muscles like glycogen, so it can be reabsorbed into the bloodstream when blood sugar levels fall. Insulin, hormone released by pancreas, regulatee levels of blood blood sugar.

excessively high blood sugar, a condition called hyperglycemia, can be caused by too large sugar or too small insulin in the blood. For example, a person who has type 1 diabetes does not produce insulin, so they usually have to receive regular insulin injections. Extremely low blood sugar can be caused by food too little food or too much insulin in the bloodstream.
