Does your diet really affect your milk?

Simply put, no matter what you eat, your body works wonders and produces the nutrients your baby needs all the time. It's a wonderful design of nature. That means you don't have to eat specific foods to give your baby nutritious milk. But, there's another side to this.

When you eat a balanced, nutritious diet , it not only increases the nutritional value of your milk, but most importantly, it gives your body the energy and nutrition it needs . Think about it, your body produces the complete nutrition that another person needs to live. So it makes sense that it needs extra energy, right? Only if you are healthy and strong will you be able to take good care of your baby.

Remember, it's especially important to drink plenty of water while breastfeeding. Try to drink at least 2-3 liters of water a day.

The composition of breast milk is also amazing. When a baby starts drinking milk, the milk that comes out (foremilk) is more watery. It quenches the baby's thirst. After drinking for a while, the milk that comes out (hindmilk) is thicker, fattier, and more nutritious. It is what fills the baby's stomach and provides the nutrients needed for growth.

So what are the best things to add to food?

While breastfeeding, you need about 500 extra calories a day. That's like an extra small meal. But it's important to get these calories from something nutritious rather than junk food.

Let's take a look at the table below to see what you should add to your diet.

Nutritional category Examples and importance
Lean ProteinThese provide the body with essential amino acids. These are very important to give you the energy you need. Examples: Chicken, fish, eggs, milk, yogurt, cheese, soy, lentils, and legumes like chickpeas.
Whole Grains These are the best sources of carbohydrates and energy. Examples: brown rice, oats, quinoa, whole grain bread, pasta.
Healthy Fats These are essential for the baby's brain development. You also get nutrients like vitamin E, Omega-3, and Omega-6. Examples: avocados, peanuts, cashews, walnuts, eggs.
Fruits and vegetables An essential part of any healthy diet. These are a good source of vitamins B1, B2, B6, vitamin C, potassium, folate, and fiber. Examples: Greens like spinach, kale, collard greens, tomatoes, bell peppers, broccoli, oranges, grapefruit, and berries.

Are there any foods that you need to limit during this time?

Some of the strict rules like during pregnancy are relaxed during this time. The fear of things like raw fish and undercooked meat can now be reduced to a great extent. However, it is very important to eat some things in moderation .

What to limit What to know
CaffeineYou don't have to completely stop drinking coffee, tea, and soda. But it's best to limit it to 1-2 cups of coffee a day. If you're having trouble sleeping or feeling restless, it can affect your baby, making him fussy and crying.
Alcohol While a small amount once in a while is not a big deal, drinking alcohol frequently and in large amounts can cause problems with your baby's sleep, weight gain, and growth. It's best to wait at least two hours after feeding your baby if you drink a little alcohol.
High-Mercury Fish This is something that should definitely be avoided . Mercury is something that can damage a baby's nervous system. Examples: Large fish like shark, swordfish, and tuna. Small fish like king mackerel, king mackerel, and herring are safe to eat.

Are there any foods that are not good for babies?

It's rare for your baby to have an allergic reaction to something you eat. But sometimes, if you eat something like dairy products (milk, cheese, yogurt), soy, wheat, or eggs and your baby develops skin rashes, eczema, vomiting, diarrhea, or excessive crying, it could be that your baby is allergic to that food.

If you suspect something like this, the best thing to do is talk to your pediatrician or family doctor. They will give you the right advice.

Is it necessary to take additional vitamins?

It's common to experience vitamin and mineral deficiencies after having a baby. So sometimes taking extra vitamins (supplements) can help keep your nutritional levels in good shape.

  • Multivitamins: Many mothers experience vitamin deficiencies after giving birth. Taking a daily multivitamin will help supplement the nutrition you get from your diet.
  • Vitamin B-12: If you are a vegan/vegetarian or have a plant-based diet, you may be deficient in vitamin B-12. This vitamin is found mostly in animal foods like fish, meat, and eggs. If so, you may want to consider taking a B-complex or B-12 supplement.
  • Vitamin D:Vitamin D is essential for your immune system and bone health. Vitamin D deficiency is common among breastfeeding mothers. It can also increase the risk of postpartum depression .

The most important thing: The American Academy of Pediatrics recommends that babies get 400 IU (International Units) of vitamin D daily from birth to 12 months. Some studies have shown that if a mother takes a daily vitamin D supplement, that amount can be passed on to her baby through breast milk.

However, before starting any of these vitamins, be sure to talk to your doctor and take them only as directed.
