I heard that when a woman has her period during breastfeeding, the milk becomes less nutritious. Is that right?

Patient's question:

It is said that during breastfeeding, when menstruation returns, the milk becomes less nutritious, right? My baby is only two and a half months old yet. Previous treatment history and effectiveness

Doctor's answer:

Menstruation brings many trace elements into the body, but it also brings many toxins. Therefore, the benefits outweigh the drawbacks. Don't put yourself under pressure.
2. The important thing isn't this, but rather how your diet is arranged. Second, lifestyle habits, emotions, and hormone levels can interfere with milk secretion.
Suggestions:
1. Balance meat and vegetables in your main meals, with each meal about seven parts full. Diversified food choices ensure better nutrition and absorption.
2. Eat less fried, pickled, and grilled foods, which are unhealthy.
