Stoewsand joined the faculty in 1967 coming from Albany Medical College. He held a prior three-year appointment at the U.S. Army Natick Laboratories, Massachusetts.
Research Interests
This research is concerned with consumer health effects of natural components and environmental contaminants present in fruits and vegetables. The general areas are: anti-carcinogens present in Brassica vegetables and wines, natural toxicants in fruits and vegetables and their products, and heavy metal toxicology when plants are cultured on waste materials, e.g. sludge, fly-ash, etc.
Currently, Stoewsand is studying the mechanism of natural sulfur compounds in brussels sprouts, broccoli, and cauliflower that exert anti-carcinogenic effects when laboratory animals are exposed to chemical carcinogens. He is also looking into the interaction mechanism of ethanol and polyphenol intake on the development of liver/lung cancer of ethyl carbamate, a compound naturally found in most fermented foods including wines and brandies. A recent research program on biotechnology risk assessment has observed natural pesticides, i.e. cholinesterase inhibitors, are present in insect resistant apples and lettuce.
