Sugar has been evidenced to have a number of detrimental effects on health. In particular, consuming sugar can cause a decrease in insulin sensitivity, and this can lead to weight gain and type 2 diabetes. The reason that sugar is so damaging is because it contains glucose and fructose, and fructose can be converted readily in the liver to fatty acids and triglycerides. These can accumulate in tissue and this can be a direct cause of insulin resistance. White bread can also be damaging to the health, and this may also relate to the detrimental effects it can have on blood sugar. However, white bread is composed of starch, and chemically starch only contains glucose, with no fructose. Because white bread is processed, it is generally digested too quickly due to the lack of fibre and this causes elevations in blood sugar levels that can cause poor blood sugar control. However, the long term damage is less severe when compared to sugar consumption because the lack of fructose limits the severity of any insulin resistance that may result.
