Importance of Good Nutrition in Pregnancy

Trying to conceive or already pregnant and looking to learn what nutritious foods are suggested for a growing baby? While you won’t need to live off salads and smoothies, there are some foods containing ingredients that are more beneficial for growth than others. We will talk about what vitamins are essential, where to find them, and I created a sample meal plan to help get you started! Pregnancy doesn’t require a strict diet but we can optimize the foods we eat most of the time and sneak in some cookies or ice cream when baby craves them (I swear it’s the baby and not us!).

When Is Nutrition Most Important In Pregnancy?

Nutrition is very important during all trimesters of pregnancy. What you eat is important even before your baby is born but not to worry, it is never too late to improve your eating habits throughout your pregnancy. Eating well is vital to helping baby grow from start to finish so being mindful of what you’re eating during these nine months will be beneficial for your little one. 

What Is the Average Weight Gain During Pregnancy?

Generally speaking, the average amount of weight women gain during pregnancy is 25-30 pounds. That number can vary based on if you are over/under weight before becoming pregnant, how much fluid your body retains, etc. If you are worried about how much weight you are gaining, please know that it is not all going to stay with you once you give birth. Weight gain during pregnancy can be attributed to amniotic fluid, placenta, increased blood volume, breast growth, increased uterus size, baby’s weight, and body fat. If you still have concerns about how much weight you are gaining, try incorporating exercise a few times a week. Studies show that strength training during pregnancy can help mom and baby.

Avg weight gain per trimester:

  • 1st trimester: 2-6 lbs, no increase in calories
  • 2nd trimester: 1 lb per week, increase caloric intake by 300 calories/day
  • 3rd trimester: 1 lb per week, increase caloric intake by 400 calories/day

What Nutrients are Essential While Pregnant?

It is important to make sure you are getting all the vital nutrients needed to help grow your developing baby. Most prenatal vitamins will have all of these vitamins in it but it may not be at the appropriate levels. Knowing what you need and why it’s important can help you be successful in a well rounded diet. I also have a full list of prenatal vitamins I take during pregnancy and why.

Folate– It’s important in the beginning of pregnancy to help develop your baby’s neural tube and prevent spinal defects such as spina bifida. The daily dose is 600 micrograms and can be found in leafy greens, broccoli, and brussels sprouts.

Omega 3– Omega 3’s are an excellent source of EPA and DHA which help develop the baby’s brain and retina. The daily dose is 200 mg and can be found in most fish and seafood. It should be in your prenatal and while the guideline is not to eat too much fish for the mercury content, try to work in smaller fish which will have lower concentrations of mercury. 

Calcium– Calcium plays the same role in babies as it does for adults- it helps build strong bones and teeth! Not to mention, it will help your bones as well. The daily dose is 1,000-1,200 mg and can be found in dairy products. If you don’t consume dairy try to incorporate beans into your diet. 

Choline– Choline is similar to folate and will be beneficial for brain development, spinal defects, and prevents mental illness for mom and baby. The daily dosi is 450 mg and can be found in eggs, beans, cod, and pork chop.

Vitamin B– Vitamin B is crucial to making red blood cells in the body. It is important to get 12400 mcg/day and is found in most meats.

Niacin (B-3)– Niacin is great for mother’s metabolism, helping with nausea, and migraines. It’s also good for baby’s development. The daily dose is 18 mg and found in most meats, avocado, tomatoes, and sweet potatoes.

Riboflavin (B-2)– Riboflavin aids in the production of energy which every mom could use! For baby’s development it’s helpful for baby’s growth, good vision, and healthy skin. Riboflavin is also essential for your baby’s bone, muscle, and nerve development. The daily dose is 1.4milligrams and can be found in dairy products, organ meats and enriched grain products

Thiamin (B-1)– Thiamin helps convert carbohydrates into energy for mom and baby. The daily dose is 1.4milligrams and is found in pork, whole grains, and lentils.

Vitamin A- Helps with growth and health of the body’s tissues and cells, especially postpartum tissue repair. It also helps support your immune system and metabolism. The daily dose is 5,000 IU and is found in sweet potatoes, carrots, spinach, milk, and liver.

Biotin– Biotin helps convert food into energy, levels blood sugar, and helps with baby’s growth. Daily dose is 30 mcg and is found in Eggs, legumes, nuts, liver, sweet potatoes, bananas, and broccoli.

What Foods Should I Avoid During Pregnancy?

Most foods that need to be avoided are due to the possible contamination of bacteria such as listeria, salmonella, and E. coli. It’s a fairly short list and is definitely worth skipping these items to avoid infection or possible miscarriage. 

Food/Drink to Avoid:

  • Deli meats
  • Sushi
  • Energy drinks
  • Fish high in mercury
  • Caffeine more than 200 mg/day
  • Alcohol
  • Raw Eggs
  • Unpasteurized cheese/milk
