Coffee May Contribute to High Blood Sugar Levels after Meals

A lot of people drink coffee for more than the caffeine kick they get from it. Coffee is the leading source of antioxidants. This is a type of molecule that inhibits oxidation caused by free radicals. The consumption of antioxidants has been linked to several health benefits including increased protection against cancer and heart disease, anti-aging, and immune system support. In addition to increased wakefulness, coffee has also been shown to protect against Parkinson’s disease, liver and colon cancer, and Type 2 Diabetes.

However, coffee has its disadvantages as well. Not only can it make you jittery and anxious if you are sensitive to caffeine or over consume it, it can also result in elevated heart rate and blood pressure. Studies have also shown that it can cause high blood sugar levels if you drink a coffee beverage after you have consumed a large meal.

According to a University of Guelph study, people who drank coffee after a high lipid (fat) meal retained 33 percent more sugar (glucose) in their blood than people who did not drink coffee after the meal. The researchers in the study think that the caffeine interfered with the communication that occurs between gastrointestinal system and the pancreas.

The pancreas is responsible for manufacturing insulin, a hormone that assists cells in using the sugar circulating in the blood. It could be that the coffee is causing a miscommunication that prevents the pancreas from producing the correct amount of insulin needed. In any event, it may be better to obtain your antioxidants from other dietary sources.
Other foods high in antioxidants include blueberries, cranberries, blackberries, plums, pecans, red beans, apples, and strawberries. Dietary supplements are also a good source of antioxidants. A registered dietician, nutritionist, or qualified healthcare provider can offer some insight into a good diet to follow for optimum health.
