The Inflammatory Question: Red Meat Might Not Be So Bad for You After AllInflammation is a risk factor for many chronic diseases, including cardiovascular disease (CVD), and the impact of diet on inflammation is an area of growing scientific interest. In particular, recommendations to limit red meat consumption are often based, in part, on old studies suggesting that red meat negatively affects inflammation – yet more recent studies have not supported this.
“The role of diet, including red meat, on inflammation and disease risk has not been adequately studied, which can lead to public health recommendations that are not based on strong evidence,” said Dr. Alexis Wood, associate professor of pediatrics – nutrition at the USDA/ARS Children’s Nutrition Research Center at Baylor College of Medicine and Texas Children’s Hospital. “Our team sought to take a closer look by using metabolite data in the blood, which can provide a more direct link between diet and health.”
Methodology and FindingsWood and her team analyzed cross-sectional data captured from approximately 4,000 older adults participating in the Multi-Ethnic Study of Atherosclerosis (MESA), and recently published their findings in The American Journal of Clinical Nutrition. Cross-sectional data is a useful source of evidence on how diet affects health; it uses data that is observed with free-living people, without attempting to influence their usual lifestyle. In this way, it may be easier to take results from such studies and apply them to non-research settings.
In addition to assessing participants’ self-reported food intake and several biomarkers, researchers also measured an array of dietary intake metabolites in blood. Plasma metabolites can help capture the effects of dietary intake as food is processed, digested, and absorbed.
