Dietitian Shares: Breastfeeding? Here’s Why You Should Eat Fish Every Week
Hey mama, are you still trying to figure out what to eat while breastfeeding? We understand that you want to take care of yourself and give your baby the best care possible. Well, one food that you should never skip? Fish. Yes, you and your baby can benefit from this delicious dish.
If you ever wondered if fish is good for breastfeeding, the answer is yes and here’s why.
It’s Great for Your Baby’s Brain
Omega-3 DHA, which is abundant in fish, especially in oily ones such as seabass and salmon. It helps to promote the development of your baby’s brain and eyes. Make sure to get enough DHA from fish, as it helps with your baby’s healthy growth, because your breast milk is a reflection of your diet.
If you are looking for fish good for breastfeeding, try fish high in healthy fats, such as sardines, mackerel, and salmon.
It Supports Your Mental Health
Postpartum depression and baby blues have been associated with low DHA in mothers. By lowering inflammation and promoting normal brain function, eating fish can support your mental health.
It Helps With Immunity & Gut Health
Plus, fish can lower inflammation and improve your gut microbiome, which will help boost your immunity and that of your unborn child.
It’s Full of Iodine
Iodine is essential for thyroid function and brain development, and your baby gets it from your breast milk. Because marine fish are a natural source of iodine, they make an ideal fish for breastfeeding mom who want to stay nourished and energised.
It May Help Prevent Fish Allergies in Babies
Believe it or not, consuming fish while breastfeeding may actually help your baby develop tolerance and lower their risk of developing fish allergies in the future.
