Can I know what we cannot eat during bf? As in eating that will drop milk supply?

Parsley may decrease your milk supply when taken in large quantities. Parsley is a diuretic and it decreases your breastmilk by decreasing the amount of water in your body. Using small amounts of fresh parsley as garnish is fine but dishes full of it can decrease your supply. My friend is a huge fan of Lebanese food and was advised to cut down on dishes like tabouleh during her breastfeeding period because of the high parsley content.
