Diabetic and non-diabetic patients alike seek answers to queries such as what are normal blood sugar levels and how to maintain them.. Normal blood sugar levels are those levels that fall within range after a glucose testing. However, others still need answers to questions on what happens if their blood sugar level spikes up. Aside from the dangers of hypoglycemia which could be fatal, other complications might also occur and may affect the vital organs of the body. Even as the body systems transform food into glucose for energy, waste products which are referred to as free radicals are created and may also cause damage to the organs as well as to the tissues of the body.

Fluctuating blood sugar levels can lead to devastating damage to the different organs of the body as the extra blood sugar combines with some proteins, collagen or enzymes and may react with the cellular DNA. Diabetic patients are at a higher risk when the body is exposed to more free radicals and other chemical reactions. Other effects may also include a faster rate in the aging process as free radicals rapidly react with other molecules that create a chain reaction in the long run. High glucose levels in blood increase the oxidation damage that is caused by free radicals.

Knowing the answer to the question on what are normal blood sugar levels is not enough as diabetics and non-diabetics need to be able to keep their glucose levels within this specified range. Excess blood sugar contributes to the production of free radicals that may be harmful too. Antioxidant-rich foods should be included in the diet not only to maintain normal blood glucose levels but to fight the harmful free radicals in the body as well. Foods that have glow glycemic index are also recommended but proper exercise and healthy lifestyle should likewise be observed.
