If you are a diabetic, sure you already are aware that your body has an inability to control levels of sugar in the blood and that you need to stay away from foods with high glycemic index (simple carbohydrates). However, recent researches point that smoking cigarettes and consuming tobacco doubles the damage to the body caused by diabetes by causing hardening of the arteries.
Nicotine & Diabetes
Smoking, in itself, poses many adverse effects on your health, but if you have diabetes and you smoke, your risk for heart associated problems, kidney disease, eye complaints (retinopathy), and other complications of diabetes increases dramatically. Not only do the risk levels rise, but existing complications can also worsen.
A research recently published in American Journal of Medicine and Diabetes have connected smoking to high risks for glucose abnormalities such as glucose intolerance and impaired fasting glucose. Smokers appeared to have a 44% higher risk of developing type 2 diabetes than non-smokers. The risk was highly linked to the smoking degree and not on the fact that whether you smoke cigars, cigarettes, or pipes. The risk increase with each cigarette you smoke and heavy smokers (at least 20 cigarettes daily) had been shown to have a 61% higher risk. On the other hand, less than 20 cigarettes daily were correlated to a 29% increase of the risk. Moreover, smoking has been shown to result in increased albuminuria (blood protein in the urine), an increased risk of damages of the nerves (neuropathy) and delayed wound healing in diabetic patients.
Caffeine & Diabetes
Other stimulants such as caffeine have also been linked to increasing the complications associated with diabetes by interfering with the movement of glucose through the body. Perhaps, stimulating the release of hormones known to boost the blood sugar levels. Further, caffeine creates a chemical called alloxan, which in turn generates free radical production. These free radicals may damage the pancreas and its ability to release insulin (the primary hormone involved in controlling normal blood sugar levels), increasing the risk to diabetes and worsening the diabetic complications.
Caffeine is found in many foods and beverages such as coffee, soft drinks, chocolates, and many supplements. Thus, the best way to limit the caffeine intake to control or prevent diabetes would be to eliminate its sources completely from your diet.
