Glycemic index is the index, which relates to the measurement or identification of impact of food on the blood sugar level of humans. Different type of food have different impact on blood sugar level, some may raise it more than others may. Foods that break down quickly during the process of digestion have the highest glycemic index and they are also known as dietary glycemic index. Glucose a type of sugar, which forms after breaking of food in the body, is the main source of energy to human body. Glycemic index helps in measuring that how fast the glucose travels and how a food affects blood glucose level. High glycemic index foods raise blood sugar level more as compared to food with low glycemic index value.

Now, body of different people reacts differently to different kinds of food that is why glycemic index cannot be generalized to one it is different for different people. Foods that have high carbohydrate content have high glycemic index and respond immediately to blood while food with low glycemic index reacts slowly and gradually with the blood. Pasta and potatoes are examples of food items, which have high glycemic index. Brown bread, soybean are examples of food items with low glycemic index. High glycemic index foods are those, which have the value of more than 70.

A proper level of glucose is to be maintained if that is not done than the person feels weak who have very low level of glucose. People tend to stop eating food with carbohydrates in order to lose their weight and because of this their glucose level is very low and they feel weak.

High glycemic index foods; watermelon, baked potatoes, rice cakes, Kaiser roll, corn chips, honey, puffed wheat, cream of wheat, mashed potatoes, and dates. Other examples of foods in this list are doughnuts, jelly beans, grape nuts flakes, French bread, tofu frozen dessert, corn flakes, pumpkin, parsnips, weetabix, coco pops, bran flakes, tapioca, puffed crisp bread, maple flavored syrup, scones, pretzels, white bread, soda crackers, Swede, millet, broad beans, carrot, biscuits and cookies.

Health is a concern for all today, be it a child's health or an adults health almost everyone today is suffering from one or the other problem, which may include diabetes, high blood pressure, obesity. In addition, among all obesity is the major one. Ranking is given from 0 to 100. Eating pure glucose will have a ranking of 100.

Food with the index ranking of 95 will give glucose as having a pure glucose but the food with index rating of 20 will not raise sugar level that much. A balance diet is very important. Having a diet with high glycemic value may increase the chances of obesity which may later lead to other problems as well. In order to lose weight food with low glycemic value is to be consumed. So consume a balance diet between low glycemic food and high glycemic food and stay healthy forever.
