  • Another look at the diet-heart hypothesis
    When you replace saturated fat with polyunsaturated fat, some studies suggest that good things should happen. But there’s more than one way to interpret the available studies.
  • Can chondroitin save knee cartilage?
    Chondroitin’s mixed results for slowing the progression of osteoarthritis may be due to the low-quality or lower-dose chondroitin used in some studies. Looking at the structural effects of higher-dose, pharmaceutical-grade chondroitin could shed more light on its efficacy

  • Interview: Matthew Dalby, PhD
    Dr. Dalby’s research explores the links between diet, obesity, and the microbiome. In this interview, we discuss fecal transplants, the role of animal models in research, and more.
