Can you naturally help regulate your menstrual cycle? like changes in diet, incorporate or avoid certain food?

Depends: It depends on what you mean by 'regulate'. A diet rich in iron can help to replenish the iron stores that are lost when you menstruate if your bleeding is heavy. If you are having specific problems with your cycle (missing periods or too frequent) there can be dietary changes that can help. Most significantly, if you are heavy, weight loss and being at healthy bmi can help regulate periods.
