CHAPTER I INTRODUCTION In the present time‚ the rate of proliferation of diabetic people is continuously and rapidly increasing. Further studies show that the number of diabetes cases worldwide has doubled since 1980 and is now at startling 350 million diabetics. (Laino‚ 2011). Diabetes is a lifelong disease in which the level of glucose in the blood is abnormally high. Connected to this is a condition called hyperglycemia. Hyperglycemia is the technical term for high blood glucose (sugar).

Apples have a good claim to promote health. They contain Vitamin C‚ which aids the immune system‚ and phenols‚ which reduce cholesterol. They also reduce tooth decay by cleaning one’s teeth and killing off bacteria. It has also been suggested by Cornell University researchers that the quercetin found in apples protects brain cells against neuron-degenerative disorders like Alzheimer’s disease. An apple a day may not keep any physicians at bay‚ but apples are very nutritious. They are high in fiber
