Raw salmon sashimi is not recommended during breastfeeding, but cooked salmon can be eaten. Salmon fillets without heating and cooking are likely to contain parasites and bacteria, which may easily cause intestinal parasites or bacterial infections after consumption by mothers and jeopardize their health, thus affecting the secretion of breast milk and the quality of breast milk, and adversely affecting the babies. Salmon usually needs to be frozen after filleting to keep it fresh. If mothers consume too much raw and cold salmon fillets, it will easily irritate the mucous membrane of the gastrointestinal tract, leading to gastrointestinal dysfunction, causing abdominal distension, diarrhea and other discomforts. Lactation can eat cooked salmon fillets, through high-temperature heating can be raw fish carrying bacteria killed, and salmon contains high-quality protein, calcium, iron, phosphorus and other nutrients. Eating salmon fillets in moderation during breastfeeding can replenish the nutrients needed by the body and promote the secretion of breast milk. Mothers need to maintain a comprehensive and balanced nutrition during breastfeeding.
