How Does Coffee Affect Blood Sugar?

Lowers Insulin Sensitivity
Some short-term metabolic research studies have showed that intake of too much of caffeine can cause a decrease in the insulin sensitivity. Because of this, the cells fail to get the effect of insulin, resulting in an increased blood level of glucose. However, lower levels of coffee consumption doesn't have any effect on the insulin sensitivity.



Impaired Glucose Tolerance
Increased intake of coffee can cause impaired glucose tolerance. This changes the blood glucose levels significantly. The normal mechanism of the body to process glucose can be impaired, resulting in a noticeable fluctuation in the blood sugar concentration.



Caffeine And Carbohydrate
Another study about the effects of coffee on blood sugar came with an interesting finding. This study showed that the concentration of blood glucose increases significantly when people, who have diabetes, eat carbohydrates immediately after drinking coffee.

Transient Insulin Resistance
Intake of coffee can cause a state of insulin resistance for a short period of time. This is called transient insulin resistance. This is considered as one of the major reasons for an increase in the blood glucose level after drinking coffee. When carbohydrate is consumed after coffee, the short-term insulin resistance can cause an increase in the blood glucose level.

Adrenaline
Coffee, with too much of caffeine, can cause an increase in the adrenaline level. Adrenaline is a hormone that has an effect on the blood glucose level. Increase in the adrenaline level can cause a temporary rise in the blood glucose level. However, this effect is only for a short period of time.

While studies show that coffee can cause a temporary increase in the blood glucose level in diabetic people, there are many other studies, which suggest that long-term intake of coffeecan decrease the chance of getting diabetes in non-diabetic people. What is your experience? Do share with us.
