10 Possible Reasons Your Daughter’s First Period Hasn’t Started Yet

2. Nutritional Status: Fueling Development

Nutrition is a cornerstone of healthy development, particularly during puberty. Adequate intake of essential nutrients supports the body's growth and hormonal balance, both of which are critical for the onset of menstruation. Malnutrition or specific nutrient deficiencies, such as iron, zinc, or vitamin D, can delay menarche. Conversely, a balanced diet rich in fruits, vegetables, whole grains, and lean proteins can promote timely development. The body's fat stores also influence the production of estrogen, a hormone crucial for menstruation. Girls with very low body fat may experience delayed periods, as their bodies prioritize essential functions over reproduction. Encouraging a healthy relationship with food and body image is vital, as is consulting with a healthcare provider if dietary concerns arise.
