The food we eat has one Altai Balance of the important nutrition called carbohydrate. During metabolism, the carbohydrate is converted into sugar. Insulin in our body absorbs the sugar and gives it to the cells. Two important activities happen. The sugar in the blood is maintained and not allowed to go high. The cells in our body get the energy.Assume for a moment that there is insulin deficiency. Obviously the blood will have more sugar. The cells will not get energy. It is fatal.
We should know that there is no substitute for natural system. If insulin is deficient, we take insulin from outside source to solve the diabetic problem. But it cannot be fool proof. There is already damage done and repairing can only be done. A repaired system cannot be brought to its original mode. In this way, a diabetic patient even if he is more careful about his insulin intake and food habits, he cannot get the benefit of the full natural system. What happens? The sugar in the blood becomes cholesterol and it is deposited in the blood vessel. That is the reason why the blood flow is hampered and not reaching the place near the wound to heal.
When blood vessels are plagued with cholesterol deposits, the arteries etc., are blocked thus free flow of blood is affected. It has the impact near the heart. The vessels near the heart, though stronger than any other place in our body is subjected to strain while pumping. In this way, the strained vessels also get damaged and leads to heart attack.
