Caffeine, a substance that occurs naturally in coffee, tea and some other Plants, is widely known as a stimulant of the central nervous system and diuretic, a substance that causes an increase in urine production. Caffeine has also been studied for its possible risks to health and benefits, including sugar, blood insulin levels and weight control. Consult your doctor before using caffeine to treat a health problem or medical condition.
Caffeine has been shown to be detrimental to insulin sensitivity in healthy individuals, as well as obese individuals and type 2 diabetics, according to a study conducted at the Department of Human Health and Nutrition Sciences of the University of Guelph, Canada. In this study, 10 healthy participants consumed coffee containing 5 mg per kg of body weight of caffeine had an hour later a high glycemic index and showed a 147 percent higher peak blood sugar and 29 percent higher insulin release in Comparison with decaffeinated coffee followed by the same meal. Coffee consumption followed by a low glycemic index meal resulted in a 216 percent higher peak blood sugar and 44 percent higher than the release of insulin from decaffeinated coffee. The researchers concluded that caffeine significantly affects the management of blood sugar and insulin resistance and recommends further investigation to confirm their results.
Consumption of caffeinated coffee may not promote weight loss and protection against type 2 diabetes, as some studies in recent years have claimed, according to a study conducted at the Department of Health and Nutritional Sciences, University of the City of New York and published in the October 2006 edition of the "American Journal of Clinical Nutrition." The protective effects associated with coffee consumption can, however, be due to weight loss as an independent factor. In some reports, coffee drinkers who lost weight showed a lower risk of type 2 diabetes, a disease that is associated with elevated insulin levels and weight gain, compared to coffee drinkers who did not lose weight. However, other studies link caffeine and possibly other components of coffee to weight loss.
Moderate consumption of caffeine, in the form of coffee consumption, was associated with a lower risk of type 2 diabetes, which implies better management of blood sugar and insulin, in the Nurses' Health Study, a study of more than 88.000 women Participants who drank between one and four cups of coffee per day had a lower risk of developing type 2 diabetes, which implies better weight control. However, the consumption of decaffeinated coffee of one cup per day produced similar results to coffee with caffeine, which indicates that there may be components that influence the blood sugar and insulin of coffee apart from caffeine. The study appeared in the February 2006 issue of the journal "Diabetes Care."
Induction of hunger
Moderate caffeine consumption decreases insulin resistance to a degree equivalent to the improvement in insulin resistance gained from some oral diabetes medications, according to Mary Vernon, MD, author of the book " Atkins Diabetes Revolution: The Innovative Program for Prevention and Control of Type 2 Diabetes. " Vernon defines moderate caffeine consumption as the amount of 1 to 2 cups of coffee and says that large amounts of caffeine, such as one that takes 4 or more glasses, can induce hunger, even when blood sugar is normal, that It leads you to eat and thus promoting weight gain.
