CEA is the abbreviation for carcinoembryonic antigen. This is a protein normally produced in the fetus while developing, but the production of CEA stops before birth. CEA levels increase in patients with breast, colon, gastric, pancreatic, and lung cancer.

In this study 60 people with type 2 diabetes (30 mne/30 women) between the age of 46 to 58 were given various dosages of Cinnamon or placebo for 40 days. Cinnamon reduced fasting blood glucose by 18-29%, triglycerides by 23-30%, LDL-cholesterol by 7-27%, and total cholesterol by 12-26%. There were no significant changes in the placebo group.
