Shan Z, et al. Overall, low-carbohydrate and low-fat diets do not affect mortality risk; however, the quality of foods consumed as part of these diets could impact mortality risk, according to a study published in JAMA Internal Medicine. Although low-carbohydrate diets are often used for weight loss and management, and low-fat diets are recommended by some dietary guidelines to help prevent chronic diseases, researchers noted that long-term health associations for both have been inconsistent. Shan and colleagues conducted a prospective cohort study of participants in the U. National Health and Nutrition Examination Survey between and Those aged 20 years and older with data available from hour dietary recalls were included in analyses. Using dietary recalls, they determined scores for overall, healthy and unhealthy low-fat diets and low-carbohydrate diets. Among 37, adults with a mean age of During that time, there were 4, deaths. Researchers found that overall low-carbohydrate diet and low-fat diet scores were not associated with mortality.

Little is known about the long-term association between low-carbohydrate diets LCDs and mortality. We evaluated the link between LCD and overall or cause-specific mortality using both individual data and pooled prospective studies. These findings were robust in sensitivity analyses. Our study suggests a potentially unfavourable association of LCD with overall and cause-specific mortality, based on both new analyses of an established cohort and by pooling previous cohort studies. Given the nature of the study, causality cannot be proven; we cannot rule out residual bias. Nevertheless, further studies are needed to extend these important findings, which if confirmed, may suggest a need to rethink recommendations for LCD in clinical practice. The pandemic of obesity is a major health issue worldwide and obesity is a predisposing factor for several chronic diseases, including cardiovascular disease CVD, hypertension, Type 2 diabetes T2DM, and cancer.
