Lean red meat consumption and lipid profiles in adolescent girls

摘要

Background Epidemiological studies of red meat consumption often fail to distinguish between leaner and fattier or processed cuts of meat. Red meat has also been frequently linked with less healthy diet patterns. Data exploring the health effects of lean red meat in younger individuals are scarce, particularly in the context of a healthy diet. The present study examined the effects of lean red meat in combination with higher intakes of fruitonstarchy vegetables on lipid profiles in older adolescent girls. Methods Data from 1461 girls who were followed for 10?years, starting at 9–10?years of age, in the National Heart Lung and Blood Institute Growth and Health Study were used. Diet was assessed using multiple sets of 3-day records collected over eight examination cycles. Outcome measures included fasting levels of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-HDL-C and triglycerides at age 18–20?years. Results After adjusting for age, race, socioeconomic status, height, activity level, hours of television per day, and intakes of whole grains and dairy foods using multivariable modelling, girls consuming ≥6?oz lean red meat per week combined with two or more servings of fruitonstarchy vegetables per day had LDL-C levels approximately 6–7?mg?dL?1 lower (P?
