1542: Fatty Acid & Inflammation/ acid metabolism

Postmenopausal women, ages 50 to 85 years

This research study will determine how diets containing three different types of fatty acids: stearic (found in cocoa butter, meats), palmitic (found in meats, dairy and some plant oils) and oleic (found in olive and corn oil) affect cardiovascular disease risk factors, with a specific emphasis on inflammation.  In addition, the purpose will be to determine how stearic acid and oleic acid are metabolized in the body.
