As growing incidence of lifestyle induced Dia-besity continues to pose a major challenge for health experts and affected individuals alike, here is some good news on diet based management of diabetes and obesity.

Scientists at the CSIR- Indian Institute of Chemical Technology [ IICT ]have analysed green yellow and red bell peppers for their anti-hyperglycaemic and anti-hyperlipidemic effect and found encouraging results.

Normally carbohydrates are broken down into disaccharides and ultimately  into glucose by the activity of alpha glucosidase enzyme present in the intestinal wall while pancreatic lipase converts lipid into fatty acids.

Interestingly the scientists found that yellow and red bell peppers slowed down digestion of carbohydrates and lipids. The research work was published recently online in Natural Products Research.

He said that once the digestion of carbohydrates and lipids get slow down the concentration of glucose and lipids in the blood would be less and as a result the chances of developing hyperglycaemia and hyperlipidemia would be reduced.

Dr Tiwari said yellow and red capsicums were more effective than green capsicum due to the presence of oligomerised anthocyanins. They were better inhibitors than pro anthocyanins found in green capsicum. He suggested eating yellow and red capsicum in raw form as salad before the main course.

Pointing out that hyperglycemia and hyperlipidemia induce oxidative strees he said yellow and red capsicums possess better anti oxidative activity than green variety. Oxidative stress gives raise to free radicals which damage biomolecules and has been implicated in many diseases including diabetic complications cardiovascular diseases and cancer.
