A recent meta-analysis of randomized clinical trials has shown that the Mediterranean diet can have a positive impact on the cardiometabolic health of children and adolescents. The study, conducted by José Francisco López-Gil, PhD, and colleagues, indicated that interventions following the Mediterranean diet led to improvements in various health markers such as blood pressure, cholesterol levels, and triglycerides among young individuals.
The meta-analysis included nine randomized clinical trials with a total of 577 participants aged 3-18 years. The results revealed that adherence to the Mediterranean diet was associated with significant reductions in systolic blood pressure, triglycerides, total cholesterol, and LDL cholesterol. Additionally, there was an increase in high-density lipoprotein cholesterol among those following the Mediterranean diet.
López-Gil emphasized the importance of incorporating dietary counseling and Mediterranean diet-based interventions into clinical practice, especially for young patients at risk of cardiometabolic issues. The findings of the study suggest that starting prevention strategies for cardiovascular disease early in life is crucial, given the link between atherosclerosis and cardiovascular risk factors in childhood and adulthood.
Despite the positive outcomes associated with the Mediterranean diet, the study authors acknowledged several limitations. Some trials included in the meta-analysis had concerns regarding bias, and not all interventions focused solely on the Mediterranean diet. There were also variations in the design of the studies, with some incorporating physical activity or exercise alongside dietary changes.
Further research is needed to determine the long-term effects of the Mediterranean diet on cardiometabolic health in children and adolescents. Subgroup analyses based on factors such as sex, race, or ethnicity could provide valuable insights into the differential impact of the diet. Additionally, exploring the effects of variables like intervention duration, age, and baseline BMI on health outcomes is essential for optimizing dietary recommendations.
The Mediterranean diet shows promise as a beneficial intervention for improving cardiometabolic health in young individuals. Clinicians and healthcare providers should consider incorporating dietary counseling and Mediterranean diet-based interventions into their practice to help prevent and manage cardiovascular risk factors in children and adolescents. Further research is needed to determine the optimal strategies for implementing the Mediterranean diet in youth populations and to assess its long-term effects on overall health and well-being.
