Researchers uncovered the relationship between our favorite beverages and diabetes. Insights about the components of coffee and tea led to the study about caffeine. Both coffee and tea contain caffeine, which reduces the blood glucose concentrations. A study conducted on 10 type 2 diabetes patients using the caffeine capsules reported that caffeine increases the blood sugar by up to 10%. The pathology of how it raises the blood sugar is still unclear but it sure opens up to more questions. If your caffeine intake is over 500 mg a day, then you may want to cut it back. The American Academy of Pediatrics recommends that young people drink no more than 100 mg of caffeine a day while children should not drink any caffeinated beverages on a regular basis at all. The tea, energy drinks, chocolates, chewing gun, sweets, and even weight loss tablets may have caffeine content.


Amazing facts about tea

Also, it may interfere with the absorption of iron from digested food. If you drink your tea in excessive amounts, it causes insomnia, anxiety, restlessness, and increased bleeding. Drinking 2 cups of tea is equivalent to 1 cup of coffee. Drinking 2 colas is equivalent to drinking 1 cup of tea.




What is in caffeine that makes it disruptive to health?

coffee tea blood sugarThe caffeine is one of the world’s highly used drugs even among the ordinary individuals as it is being regularly consumed in drinking beverages such as tea, coffee, energy drinks or colas, and of course, by eating chocolates. In the US, adults regularly consume caffeine at an average of 2 to 3 cups of coffee a day. The consumption of caffeine leads to behavioral, autonomic, and endocrine responses. It activates the central nervous system, which may have a pathogenic effect when combined with stress. The caffeine has direct influence on the heart and blood vessels as well as elevates the stress hormone section. Several studies show that the normal dietary intake of caffeine ranges from an estimated of 50 to 1500 mg per day. This corresponds to a consumption of 1 soft drink up to 15 cups of coffee per day.


The caffeine is rapidly and completely absorbed after ingestion, appearing in the bloodstream after 10 min. The peak concentrations are generally reached in about 45 to 90 min. The caffeine concentrations and the resultant physiological effects can persist for many hours after oral ingestion from beverages, foods, or medications. The caffeine has the ability to exert widespread effects on the glucose metabolism and control. This could be a negative role in the management of diabetes. Studies in the late 1960s and 1970s reported that moderate doses of caffeine from instant coffee impairs glucose tolerance. Caffeine could adversely affect the glucose levels and its regulation. Caffeine can reduce hepatic glucose production.

A study closely associated the fracture incidence among mid and old age women to an increased risk of hip fractures. The interaction between dietary calcium and caffeine on bone density demonstrates that women with low dietary calcium of less than 800 mg of calcium per day tend to have lower bone density if heavy coffee drinkers. For those women not drinking at least a glass of milk on a daily basis, but drinking 2 or more cups of coffee a day were seen with a decreased bone density. The risk for osteoporosis or lower bone density seem to increase when the consumption of coffee exceeds 2 cups a day.

A person’s caffeine intolerance gradually increases as one progresses through ages 40, 50, 60, and beyond. Sometimes fasciculations are associated with painful muscle cramps. In a recent study, caffeine was found to raise both the blood sugar and insulin. This effect may be greater in some people than others. The effects of caffeine in your body may largely differ depending on your personality type and how much stress you are under. The caffeine magnifies stress significantly and can make you even touchier exploding at the slightest irritation. Sugar is seen to accelerate aging in many men and women.
