Tune in to this episode to learn about the details of a new research study as well as an in-depth discussion about the strengths and limitations of different types of nutrition research including randomized controlled trials, observational studies and industry funded research.

Nearly half of all American adults are living with some form of cardiovascular disease and 10 percent of Americans have type 2 diabetes, making it more important than ever that people have accurate, science-based nutrition advice to support a healthy diet. Relatively few studies have directly assessed the influence of specific foods, including red meat and beef, or dietary patterns on insulin sensitivity. Most recommendations have been based on observational studies, which do not illustrate cause and effect for these foods. New research, published in the Journal of Nutrition, compared the effect of following what the USDA defines as a Healthy U.S.-Style Eating Pattern to a modified version with an increased amount of lean beef. Then the researchers measured diabetes risks factors like insulin sensitivity and other cardiovascular disease risk factors.
