Research Interests

The focus of Dr. Martin's research has been on nutrient sensing mechanisms in the gut and brain and how these mechanisms may be altered by dietary fermentable carbohydrates, gut microbiota and metabolic end products. It has been shown that dietary fermentable carbohydrates decrease plasma cholesterol and triglycerides, improve insulin sensitivity, decrease obesity, and produce anticancer effects in humans.
