Overview

• A study of over 7,500 U.S. girls found that healthier diets in childhood are associated with a later onset of menstruation, independent of BMI and height.
• Diets high in fruits, vegetables, whole grains, and legumes delayed menarche, while inflammatory diets with processed meats, refined grains, and sugary drinks hastened it.
• Early menarche is linked to increased lifetime risks of breast cancer, cardiovascular disease, and diabetes, highlighting the long-term health implications of childhood diet.
• Researchers advocate for evidence-based school meal programs and broader access to nutritious foods for children and adolescents to support healthier development.
• The findings underscore the role of diet in influencing puberty timing through inflammatory pathways, warranting further research in more diverse populations.
