Sugar and Diabetes

As diabetes is a condition characterized by elevated concentrations of blood sugar, many people ask if eating sugar may trigger it. Although eating huge amounts of sugar could increase the risk of developing diabetes, sugar consumption is only one component of the puzzle. Numerous other factors -- such as lifestyle, diet, and genetics, affect your risk. Know about diabetes treatment.

How does sugar affect diabetes?

Diabetes affects your body’s ability to regulate glucose levels. Usually, type 1 is a result of autoimmune damage caused to the immune system which makes your body incapable of producing insulin which causes the inability to reduce sugar levels in your body. Likewise, in type 2 your body does produce insulin but the quantity produced is not optimum or the body is not able to efficiently use the insulin produced. 

For a adult person are advised to consume no more than 30g of sugar per day, or around seven teaspoons. If you are diabetic then your daily sugar intake should be your enemy as sugars and refined carbs are absorbed quickly into the bloodstream and result in elevated blood sugar levels. Being a diabetic your blood has high glucose levels due to its inefficiency to transport it to the cells. Having diabetes if you fail to manage your sugar intake you become prone to severe complications that might even result in death. Also know is sugarcane juice good for health.

What is Diabetes and Its Causes?

It is a condition wherein the body's ability to control your blood sugar level is diminished. It could occur when the pancreas stops making enough insulin, and your cells develop intolerance toward the produced insulin. Insulin is the primary hormone used for sugar absorption from your bloodstream into your cells in the form of energy. 

Blood sugar levels that are high for a prolonged period could cause complications, such as the increased risk of developing heart disease, kidney and nerve damage; therefore, it is essential to ensure they are in good order.

There are prime forms of diabetes, each having distinct causes:

Type 1: Occurs as your immune system attacks your pancreas, which destroys its ability to make insulin.

Type 2: Occurs when the pancreas stops producing enough insulin to manage blood sugar levels.

Type 1 sugar diabetes is rare, primarily genetic, and is only responsible for 5-10 % of all cases of diabetes. 

Type 2 diabetes is responsible for greater than 90% of all diabetes cases and is usually triggered by lifestyle and diet. Also know more about diabetes diet chart.

This results in an increase in blood sugar levels which is a signal for the pancreas to release insulin. The hormone insulin commutes the glucose from the bloodstream into the cells where it can be metabolized and used as energy. A major amount of fructose is transported to the liver where it gets transformed into glucose for energy or is stored as fat. A small amount of fructose is also used by cells as energy.
