In 2013, I had a thiamin deficiency. Not my proudest moment as a functional nutritionist, but hey, I relearned something I didn’t think would affect me. At the height of my green juicing habit, I was consuming lots of blueberries and LOTS of kale. I love kale; in my smoothie at breakfast, a kale salad at lunch, and oh heck I’ll through some in my soup/stir fry/dinner tonight, too. Well, kale and blueberries contain an anti-nutrient called anti-thiaminase. As you can surmise, anti-nutrient means it interferes with the utilization or absorption of a particular nutrient and that’s how I ended up with a thiamin deficiency. So I sadly said adieu to kale for a while, saved some blueberries for the rest of the planet and stocked my fridge with other fruit and veggies.
Now with the recent addition of our precious new niece Anna, and counseling several new mommies and mommies to be, I can’t stop reading about how nutrition affects the growing fetus. This video by Dr. Michael Gregor at NutritionFacts.org, illustrates the point that what we eat tells the body how to behave. Nutrients not only become the structure of our bodies, they are also messengers that deliver instructions on how to put together the structures in our bodies. While I am, admittedly, a whole food zealot, I have concerns about optimizing intake while not flooding the body with ‘messages’ that might in fact be harmful. The possibility that Mother Nature’s closing of a specialized opening in the heart might be adversely affected by high doses of antioxidants gets my attention. As does the research on depression, cardiovascular health, and immunity, all affected by the signaling molecules called nutrients that speak to developing DNA in utero. This ‘programmed DNA’ then dictates the health of the new human into adulthood. I always advocate a plant based diet, including plenty of vegetables and fruit during pregnancy. However, guzzling concentrated sources of polyphenols and other antioxidants via dehydrated powders and concentrated juices on a daily basis may not be the best advice we can give. In hopes of creating the best developmental environment possible for a developing fetus, 2-3 servings of fruit and veggies at each meal, in their whole unprocessed states seem more appropriate. And yes, paternal nutrition affects the health of the fetus, too. If you are pregnant or soon to be, I hope you watch the video and check out the links above. As the wise Michael Pollan reminds us: eat real food (not powdered, processed ‘health’ food), not too much (optimize, don’t flood the system), mostly plants (yep, plants heal).
