Selection criteria for the study included the following for people with type 2 diabetes: age >40 years, not on insulin therapy, not taking medicine for other health conditions, and fasting blood glucose levels between 7.8 and 22.2 mmol/l (140–400 mg/dl). This study was conducted in the Department of Human Nutrition, NWFP Agricultural University, Peshawar, Pakistan and was approved by the Ethics Committee and Human Studies Review Board of the University of Peshawar. Examples of these include bitter melon, Gymnema, Korean ginseng, onions, garlic, flaxseed meal, and specific nutrients including α-lipoic acid, biotin, carnitine, vanadium, chromium, magnesium, zinc, and vitamins B 3, E, and K ( 5). A number of medicinal/culinary herbs have been reported to yield hypoglycemic effects in patients with diabetes.

Botanical products can improve glucose metabolism and the overall condition of individuals with diabetes not only by hypoglycemic effects but also by improving lipid metabolism, antioxidant status, and capillary function ( 4). Spices such as cinnamon, cloves, bay leaves, and turmeric display insulin-enhancing activity in vitro ( 2, 3). The dietary components beneficial in the prevention and treatment of these diseases have not been clearly defined, but it is postulated that spices may play a role. Although the causes of type 2 diabetes and cardiovascular diseases are multifactorial, diet definitely plays a role in the incidence and severity of these diseases. The incidence of cardiovascular diseases is increased two- to fourfold in people with type 2 diabetes ( 1). Changes in HDL cholesterol were not significant.ĬONCLUSIONS-The results of this study demonstrate that intake of 1, 3, or 6 g of cinnamon per day reduces serum glucose, triglyceride, LDL cholesterol, and total cholesterol in people with type 2 diabetes and suggest that the inclusion of cinnamon in the diet of people with type 2 diabetes will reduce risk factors associated with diabetes and cardiovascular diseases. RESULTS-After 40 days, all three levels of cinnamon reduced the mean fasting serum glucose (18–29%), triglyceride (23–30%), LDL cholesterol (7–27%), and total cholesterol (12–26%) levels no significant changes were noted in the placebo groups. The cinnamon was consumed for 40 days followed by a 20-day washout period. Groups 1, 2, and 3 consumed 1, 3, or 6 g of cinnamon daily, respectively, and groups 4, 5, and 6 were given placebo capsules corresponding to the number of capsules consumed for the three levels of cinnamon. RESEARCH DESIGN AND METHODS-A total of 60 people with type 2 diabetes, 30 men and 30 women aged 52.2 ± 6.32 years, were divided randomly into six groups. OBJECTIVE-The objective of this study was to determine whether cinnamon improves blood glucose, triglyceride, total cholesterol, HDL cholesterol, and LDL cholesterol levels in people with type 2 diabetes.
