Menstruation is a normal biological process that many women go through. In simpler terms, menstrual cycle (period) occurs when the uterus sheds its inner lining of blood and tissues each month. A regular period cycle happens every 28-35 days. While many women go through this, their periods are different from each other. While some women have periods in regular intervals, others may experience irregular periods, meaning their periods could be much more apart in days than the usual time. Usually, periods can start any time after the age of 8 and before 17 and it is the first sign of puberty. The Cleveland Clinic explains that first periods, that menarche, which symbolizes the fact that your body is mature enough to grow a fetus. There are many things that can influence menarche like hereditary, your genes could play a part in when you period starts, hormones, body composition, health etc. A new study published in the Human Reproduction journal showed that there is a possible connection between a child's diet and the timing of puberty. What They Eat Can Affect Periods Researchers found that for girls, eating more foods that can cause swelling inside the body might lead to their first period starting sooner. These kinds of foods are sometimes called "inflammatory." The study showed that girls who ate more of these foods had a 15% higher chance of getting their first period in the next month. This suggests that what girls eat could have a quick effect on when they reach this important milestone in their development. It highlights how diet might have a direct impact on the body's timing. What Are Inflammatory Foods? Inflammatory foods are types of food that can cause ongoing swelling throughout your body, known as chronic, systemic inflammation. These foods include things like red and processed meats, commercially baked goods, white bread and pasta, deep-fried foods, and items high in added sugar or sugar-sweetened drinks. Eating a lot of these foods might make inflammation worse, which has been linked to health problems like heart disease and diabetes. So, choosing to eat less of these could be better for your overall health. Healthier Diets Associated with Later Onset On the other hand, the study also found that eating a healthier diet seemed to push back the timing of a girl's first period. When girls ate more nutritious foods, the chances of them getting their first period in the next month went down by about 8%. This suggests that a good diet might help the body develop at a slightly slower pace when it comes to puberty. The researchers studied data of over 7,500 kids between the ages of 9 and 14. They discovered that the link between diet and when girls got their first period was still there even when they considered the kids' body size. Body Mass Index (BMI) is a way to estimate body fat based on height and weight. The fact that the connection remained even after considering BMI suggests that it's not just about being bigger that causes earlier puberty; something else in an unhealthy diet might be playing a role. Dietary Recommendations for Children The access to healthy foods plays a really important role. They stressed that it's really important for all kids and teenagers to have access to healthy food. The researchers pointed out that the food served at schools for breakfast and lunch should follow good, science-backed guidelines. This would help make sure that all children have the chance to eat nutritious meals, which could have a positive impact on their health and development, including when they start puberty. Making healthy food available to everyone is a big step.
