Is white sugah good for health?

White sugar is polished and refined sugar. It has a high glyciemic index (Glycemic index) GI represents the total rise in your blood sugar level following consumption of the food. White sugar probably has a GI of around 96 which is pretty close to the highest (100 of pure glucose).

Hence it is unhealthy because the body is unable to burn off this sudden spike in glucose levels.

It is often said that brown sugar is a healthier option than white sugar ... Because of its molasses content, brown sugar does contain certain minerals, most notably calcium, potassium, iron and magnesium (white sugar contains none of these).
