Fertility Diet - Is Plant-based the best choice?
Science and human experience tell us that an omnivorous diet is the best choice.

Let's look at what the American Academy of Pediatrics says about early life nutrition, starting at conception: (those critical First 1000 Days)
"Although all nutrients are necessary for brain growth, key nutrients that support neurodevelopment include protein; zinc; iron; choline; folate; iodine; vitamins A, D, B6, and B12; and long-chain polyunsaturated fatty acids. Failure to provide key nutrients during this critical period of brain development may result in lifelong deficits in brain function despite subsequent nutrient repletion. Understanding the complex interplay of micro- and macronutrients and neurodevelopment is key to moving beyond simply recommending a “good diet” to optimizing nutrient delivery for the developing child." (1)
When you work with me, I will teach you how to "move beyond a good diet to optimizing nutrient delivery" for you and your baby-to-be. I will make sure you get the right balance of micro- and macronutrients so you and your baby will thrive.
Reasons why not to eat a largely or exclusively plant-based diet when trying to conceive or pregnant:
- Some of those "key nutrients" are only found in animal foods: B12, DHA and ARA (the two critical long-chain polyunsaturated fatty acids), and heme iron (the most bioavailable form).
- True vitamin A, AKA retinol, is also only found in animal foods, the plant-based form is inadequate for many women due to genetics (BCOM polymorphisms) and a variety of other factors. Because this is a critical but under-recognized issue, I wrote comprehensive articles on this. (2,3)
- The best sources of choline are eggs, seafood, and organ meats.
- Zinc from shellfish, meat, poultry, and even dairy is significantly easier to assimilate than from legumes and other plant foods; I can teach you however how to maximize your zinc absorption from plant foods.
- Iron deficiency during pregnancy is much more a risk for women who choose vegetarian or vegan diets. Iron supplements can help, but heme iron from meat and organ meats, along with cofactors like vitamins A, B6, and B12 in these meats, can be instrumental in keeping blood counts in the optimal range. This is so important for your baby's brain!
- Best dietary source of iodine is shellfish and seaweed, similarly for selenium; both of these trace minerals work together to support thyroid and central nervous system development and function.
- Traditional cultures always valued a variety of animal foods as essential for couples anticipating pregnancy.
In a 2018 article, scientists from the University of Toronto and Columbia University (4) scored foods according to the amount of essential nutrients they contain that support mental health (folate, iron, long-chain omega-3 polyunsaturated fatty acids, magnesium, potassium, selenium, vitamins A, B1, B6, B12, and C, and zinc - they were looking specifically at the benefits of these "anti-depressive" nutrients, but you can see how this nutrient list is similar to the AAP list.) The highest scoring animal foods were oysters/mussels/clams, various seafoods including fish eggs, and organ meats for several of these nutrients. The highest scoring plant foods were leafy greens, peppers, and cruciferous vegetables. Animal-sourced foods vs. plant-based foods differ in these essential nutrients, so it is important to balance them.
I have always recommended an omnivorous diet for women and their partners desiring a healthy pregnancy. However, not everyone will eat enough of the variety of foods that score highest in these critical vitamins and minerals for a baby's development. Because of this, I will first determine where your diet is lacking based on your signs, symptoms, available bloodwork, and dietary records, along with ongoing confirmation by additional targeted labs. Then we will work together to design an eating plan and prenatal vitamin choice that ensures you meet every single important nutrient target. I will also make sure you get the right balance of macros, avoid foods high in anti-nutrients, and get to an optimal body composition. Through this individualized guidance, optimizing your energy and gut health will also be a focus of my recommendations.
