Macronutrients are the basic building blocks that allow our bodies to generate energy, in the form of calories. The 3 macronurtients are:
Our bodies require fat for healthy cellular structure and function. Breast milk is a perfect example of how nature gets it right, as it is made up of 55% fat, 38% carbohydrates, and 7% protein. Also, eating fats with vegetables (i.e. olive oil on a salad or steamed veggies) helps your body better absorb vitamins A, D, E, and K. These vitamins will support a healthy cell function in mom and growth of baby. Protein is important for muscle creation. However, studies have found that pregnant hunter gather women are mildly adverse to protein intake. This is due to a decrease in the body's ability to make urea, a waste product of protein metabolism. Typically, a pregnant body will crave less protein. If the body require more protein, she will crave more. The prental body needs 10-15% protein, which equates to 50-75 grams (g): 1 egg has 6 g, 1 cup of chicken breast has 43 g, 1 cup of black beans has 39 g.
Major prenatal nutrition goals:
- Eat real, whole foods
- Maintain steady blood sugar levels
- Maintain steady blood pressure levels
- Incorporate essential nutrients to support developing baby and maintain mom's health
- Reduce risk of gestational diabetes, pre-eclampsia, over or under weight gains
- Promote best post-partum recovery

Beyond a prenatal vitamin there are 3 other essential nutrients for building baby.
Vitamin D3 is a hormone that influences almost every cell in your body, and has been linked to boosting fertility rates in women and men.
Vitamin D benefits:
- Improves reproductive health
- Improves sperm quality and count
- Higher fertilization and implantation rates
- Lower risk of miscarriages
- Reduces risk of pre-eclampsia, premature delivery, and pregnancy complications
- Enhances immune system
- Decreased risk of infection, asthma, and eczema in baby
It is recommended to have your vitamin D levels (serum 25(OH)D) checked prior to supplementing. Optimal vitamin D levels are between 50-100 ng/mL. A minimum of 50 ng/mL is recommended to be hormonally healthy. Maternal levels greater than 65 ng/dL are optimal for transferring vitamin D to infant while breast feeding. The general recommended dosage is 2,000-4,000 IU per day to meet your body's needs; however, higher dosage may be necessary depending on you level.
Fish Oil/Omega 3 Fatty Acids (EPA and DHA) are important in promoting fertility and development of your baby's brain, eyes, and heart during pregnancy.
Fish oil benefits:
- Regulate hormones and increase blood flow to the uterus
- Help normalize menstrual cycle
- Promote ovulation
- Increase white cervical mucus to help the sperm reach the egg
- Produce healthier sperm
- Higher rates of conception
- Lower rates of miscarriage and premature birth
- Decreases chances of developing postpartum depression
- EPA is necessary to grow a healthy circulatory system (heart and blood vessels)
- DHA is important to build a healthy central nervous system (brain and spinal cord)
Sources of fish oil:
- Dietary: fish, eggs, meat, nuts, seeds, dark greens, and leafy vegetables
- Supplements: 1,000 - 3,000 mg/day
Probiotics help to establish a healthy microbiome. Microbes (bacteria, viruses, and fungi) colonize our mouth, gut, genitourinary tract, skin, and breastmilk. Supplementing with probiotics (10-20 billion c.f.u/day) will support a healthy immune system and digestion during pregnancy. During vaginal delivery mom gives baby their first dose of microbes. She continues to share and help baby's colonization through skin on skin contact and nursing, which helps the developing immune system and digestion.
