I’ve had some (panicked) questions about the recent articles on folic acid supplementation during pregnancy and increased risk of autism. Let’s chat science:
1. This study is what is called an Observational Study. Do these types of studies have their merits? Absolutely. Do they establish causation? Absolutely NOT. This study looked at blood levels of folate and B12 in newborns 24-72 hours after birth, and then the development of ASD later in life. A correlation was established. Correlation – just like how eating ice cream increases your risk of being bitten by a shark.
“LOGIC”: eating ice cream happens more in the summer –> the summer equals more people swimming in the ocean –> more people swimming in the ocean increases the risk of shark attacks, therefore eating ice cream –> increased risk of shark attack. Absurd.
Now it’s important to not simply throw out a study because it’s correlational. Correlational studies are the jumping off point for mechanistic studies. But, we can’t make recommendations, especially dramatic ones, on correlation.
2. No mechanism is established. But you know what we do have a mechanism for? Folate deficiency and neural tube defects. The neural tube is the part of the embryo that turns into the spine. It closes at 3 weeks post-conception, and REQUIRES folate to do so successfully. There is a known, causal mechanism for folate deficiency and NTDs like spina bifida. And the fact that it is required so early in pregnancy, before many women know they’re pregnant, shows how important it is to be taking folate (or eating a TON of leafy greens and chicken livers) prior to conceiving.
3. Population. Direct quote from the study:
“Data are from the Boston Birth Cohort…that recruited low-income urban, primarily minority mother-offspring pairs…followed them from birth through childhood…”
There are many confounding factors in that statement alone. For example, income is the number one determinant of health. This shows that it is important to analyze the actual study, instead of just reading a headline.
4. Folate vs. Folic Acid. Have you noticed that I’ve only used the word “folate” thus far? That’s because FOLATE is the food-based version of this important B vitamin. It’s the one the body needs and recognizes as usable. Folic Acid is a synthetic form of folate – it is not the same thing, and in some cases (usually with genetic anomalies) it can cause problems. Most people uses these 2 terms interchangeably but I cannot stress the importance of recognizing the difference. Finding a pre-natal supplement that contains FOLATE is challenging, but there are a few out there. You want to look for something that says “folate” or “active folate” or “methylated folate”. My favourite is Designs for Health, in combination with lots of leafy greens and regular liver consumption.
5. More isn’t better, it’s just more. As with all supplementation, more isn’t better. Follow your practitioner’s recommendations for the amount of folate to consume (just make sure it’s folate, not folic acid, and make sure that if your practitioner wants you to stop supplementing, they read the STUDY not the news article…otherwise get a second opinion.) Better yet, get most of it from your food. Leafy greens and chicken livers are your best sources!
6. Nutrients do not work in isolation. High levels of plasma folate and B12 indicate a metabolic issue – either stemming from a genetic anomaly (like the MTHFR mutation) or more often, other nutrient deficiencies. A diet high in all the nutrients (as in, not just from a pre-natal, but from consuming lots of vegetables, fruit, liver, meat, fish, eggs and quality fats) is required for all systems to function properly. Check out my free handout for a nutrient dense diet for fertility and pregnancy.
7. The media and nutrition. This is a post in and of itself, but to sum up quickly – the media should be ashamed of themselves for the way they create fear through headlines. No one ever reads the study before creating a shocking, and terrifying title. Case in point this study – the study authors conclusion:
“In this urban low-income minority birth cohort, we observed an elevated risk of ASD associated with high maternal plasma folate levels (>59 nmol/L), which far exceeds the excess cutoff suggested by the WHO (>45.3 nmol/L); however reported maternal vitamin supplementation was protective. Excess maternal vitamin B12 (>600 pmol/L) in pregnancy was also shown to be associated with greater ASD risk in offspring. The risk of ASD was highest if mothers had both excess prenatal folate and vitamin B12 levels. Our findings warrant additional investigation and highlight the need to identify optimum prenatal folate and vitamin B12 levels that maximize health benefits, at the same time minimize the risk of excess and its associated adverse consequences such as ASD.”
“Our work is very consistent with previous work showing that supplementation is critical to maternal health and child development and health, so at this point the recommendation is definitely to continue supplementation. What this study finds is that while maintaining adequate levels of folate is important, extreme levels may be harmful.”
What does all that mean?
Continue supplementing during pregnancy!
In summary, please do not freak out if you’ve been taking prenatals thus far. They are incredibly important (and this is coming from someone who prefers food over supplements most of the time!). Ideally switch to a version that contains folate, the active form of the nutrient recognized by the body. Keep the diet incredibly rich in nutrients by focusing on lots of leafy greens, quality meat & organ meats, egg yolks, fish, grass-fed dairy (if tolerated), bone broth and probiotic-rich foods (like sauerkraut & kombucha).
This recipe sounds fancy. It looks fancy. It tastes fancy. But it’s so darn easy. Which is amazing, since over or under cooking fish is the worst!!
If you follow me on Instagram, you might be familiar with our #TacoTuesday tradition. Since we work late on Tuesdays, we need to make something quick for dinner. Lettuce Wrap Taco‘s have been our go-to for years, however with the recent changes in my life (a.k.a. pregnancy) I’ve been doing everything possible to get as much seafood in my diet as I can.
“Why fish?”, you might ask… well the omega-3 fat found in fish, especially cold-water fish like salmon, is one of the most important (and least consumed) nutrients in our diet. The particular omega-3’s found in fish are EPA and DHA and are absolutely essential for proper development, not to mention all around heath. Here’s why:
EPA & DHA make our cell membranes function better. Since our cell membranes are the brain of the cell (yep, that’s a major dogma shift from what most of us were taught back in highschool/university. The nucleus is in fact, NOT the brain of the cell, it is simply the gonads) if our cell membranes work better, cells work better, which means the tissues that they are a part of work better. All of our organs and systems in our entire bodies work better when our individual cell membranes work better. (note: this is also why we want to avoid vegetable oils because they do the exact opposite)
EPA & DHA have a critical role in the development of the nervous system (brain, spinal cord, nerves, eyes).
EPA & DHA are powerfully anti-inflammatory. They provide the building blocks for our endogenous anti-inflammatory molecules known as cytokines. (note: vegetable oils do the opposite, they feed into our pro-inflammatory pathways)
There are 2 very important things to note about omega-3 oils:
The omega-3’s found in plants (flax, walnuts, chia etc.) are not the same. They are a different kind of omega-3 known as ALA. And while we can convert some to the usable form, the amount we can convert is in the range of 1-3% – and that’s with an optimally functioning body, which most people do not have. Which means it would take a cup of flax oil to provide the same health benefits as a few bites of salmon.
Fish oil supplements only work in the short term. Once you pass 6 weeks, the benefits peter out. So a supplement will not suffice.
So what does that mean? Well, it’s time to start eating fish my friends. Not a fan? At risk of sounding like a total jerk, that’s kind of not an option if you want to make sure you’re hitting your required nutrients. Now I appreciate that some people have fish/seafood allergies, so that definitely is a roadblock, but unless that’s your case, start learning and wanting to develop a taste for it (trust me – I get it. I did not like liver. But I knew how important it was, so I set my mind to it and learned to like it.) If you are in the transition of learning to like fish, or you are allergic, the only other places you can find usable omega-3 fats in are grassfed beef and pastured egg yolks.
As with all food, the better the quality, the better the nutrition. For fish you want to try and purchase wild, sustainably caught species whenever possible. That can be challenging to find (and crazy expensive) in the middle of the continent, but luckily demand is going up, so places like Costco (where I get my frozen, wild salmon) are carrying more of this type of product! Though it definitely comes at a price, so you want to make sure you cook it up nicely!
Enter: Salmon en Papillote
This meal can be pulled together in 15 minutes flat – as long as the fish is thawed. It pairs beautifully with rice (cooked in bone broth of course!), cauli-rice, steamed potatoes or a simple salad.
Aside from being incredibly heathy and the minimal prep/cook time, one of the best features of this meal is it is super scalable. Last night I made it for just me (not too shabby for a solo dinner eh?) and I’ve also made it for a large dinner party.
The ingredients are very flexible as well, although I am partial to the ones I use! However if you need to avoid nightshades, simply omit the red peppers and if desired, sub another vegetable like yellow squash or bok choy.
Finally, while I made this particular one in the oven, you have the option of using the BBQ as well. We often do that in the summer to keep the house cool!
Salmon en Papillote
Sounds, looks and tastes fancy - actually super simple! Not to mention delicious and nutritious!
It’s pretty hard to look at any health-related article these days, without seeing the microbiome mentioned at least once! And for good reason. The microbiome (or flora) is the sum total of all the critters that live in your gut (and skin, vaginal tract etc.). By critters I mean bacteria, viruses, yeast, fungi, parasites. There are about 100 trillion microorganism cells in/on our body – which is about 10 times the amount of human cells we have. So what that means is we are more bacteria than we are human!
So far we know that the make up of your gut flora is absolutely critical to determining your health. We also seem to understand that what we know is only the tip of the iceberg. Some of the functions we know they are responsible for are:
create food for your intestinal cells
prime your immune system and support lymph tissue surrounding the intestinal tract (known as the GALT)
digest your food
release vitamins that are bound up in fibres
maintain the integrity of your intestinal tract
synthesize vitamins (like vitamin K and some B vitamins)
suppress pathogenic and opportunistic microbial growth
compose about 75% of our immune system
Dysregulated Microbiome (a.k.a. Dysbiosis)
When the opportunistic or pathogenic microbes overgrow and take over the good guys, you get a state of dysbiosis. Dysbiosis, or an imbalance in gut flora, has been associated with:
autism spectrum disorder
type 1 diabetes
inflammatory bowel disease
and many more diseases (pretty much any area of health which we don’t understand, and actually lots of those that we do, have cutting edge research being done on how the gut flora impact/contribute to that disease)
This imbalance is caused by 3 things:
consuming foods that promote overgrowth (sugar, refined carbs, vegetable oils, too much fat, gluten, whole grains, legumes) or foods that you are sensitive to
not consuming enough vegetables (both non-starchy and starchy), the food for beneficial flora
not consuming beneficial bacteria regularly as part of your diet
Why Fermented Foods?
Fermented foods are the original probiotic. In an effort to preserve vegetables and have them last through the winter, humans started to ferment them. With the advent of refrigeration, we stopped needing to ferment veggies to preserve them. Unfortunately we didn’t realize how much we actually needed the byproduct of fermentation – probiotics.
Food > Supplement
So why consume fermented foods if you can take a probiotic? Well, the top of the line, highest quality probiotic supplements usually contain between 4-10 strains of bacteria. Homemade sauerkraut can contain between 50 and 500 different strains. And what’s most important for creating a healthy gut microbiome, is variety and frequency.
So choosing a variety of different types of foods – fermented vegetables like sauerkraut, homemade yogurt (either grassfed dairy or coconut) and kombucha – on a daily basis is a fabulous way to constantly be reinoculating your gut with a wide variety of beneficial critters.
Kombucha is one of my favourite fermented foods – mostly because it tastes way more like a treat, than a ferment like sauerkraut. Full disclosure, it’s not nearly as rich in numbers or variety of bacteria, but it does have one good thing going for it. It’s filled with beneficial yeast, who do an awesome job at keeping opportunistic yeast (like Candida) from overgrowing. So while I love the ‘booch, I don’t recommend relying on it as your main source of probiotics.
NOTE: during my first trimester my sour taste buds were like on steroids. Salad dressings, grapefruit, even romaine lettuce were painfully sour. So you can imagine what fermented veggies were like. The only fermented food I could tolerate was kombucha!
Making Your Own Kombucha
As much as I love kombucha, it can get real expensive. A bottle of GT’s (a popular brand) ranges from $3.70-$4.99 – which adds up quick! So when I started consuming ‘booch regularly (instead of just as a treat), I knew I had to make my own otherwise I’d drink us out of house and home! It took me a while to get a routine going, and there are lot of variations out there, but this is how I do it and I’ve been very successful for months now!
1L purified water (divided into 2x 2 cups)
1 organic tea bag, plain black
¼ cup organic sugar cane
¼ cup kombucha from a previous batch
1 small SCOBY (symbiotic culture of bacteria and yeast – this little mushroom like thing that floats around in your liquid, eats up the sugar and infuses your beverage with gut-healing magic. Note – the SCOBY seen in the pictures below is HUGE because I’ve been using it with high volume continue kombucha brewing for about a year now. Most are just a few inches in diameter.)
Directions – Part 1
Boil 2 cups of the water in a small pot.
Once boiled, stir in the sugar until fully dissolved.
Add the tea bag. You’re now making sweet tea! (note, I’m making a quadruple batch here)
Add remaining 2 cups of water (to help speed up the cooling down process).
Cover the pot with a lid and let cool to room temperature. You can put it in the fridge for a few hours to help speed up the process, but don’t let it get too cold.
Once it’s at room temperature, pour the sweet tea into a clean jar, add the SCOBY and kombucha from a previous batch.
Cover with a coffee filter or dish towel and let sit in a cool, dark place for 2 weeks.
Once the 2 weeks are up, pour off almost all of the kombucha into a separate jar or juice jug, retaining enough to make another batch.
You have the option to do a 2nd fermentation at this point, but I didn’t like the hassle so I don’t do it. Feel free to google it if you’re interested in a more fizzy beverage!
Add flavour to your kombucha. My favourites are:
lemon / ginger
Store kombucha, with the flavouring in it, in the fridge!
Meanwhile, repeat Part 1, with the leftover kombucha you retained.
Every other Friday I make a new batch of kombucha. I start with Part 1, but since I have an old batch going, as soon as the new sweet tea is cooled to room temperature, I begin Part 2. I empty out most of the 2 week fermented kombucha into juice jugs with flavouring, leaving the SCOBY and enough kombucha in the bottom for the next batch. Then I pour the cooled sweet tea in and recover. Takes me about 20 minutes (plus a few hours wait time) every 2 weeks.
Start tasting the kombucha after 1 week to make sure you achieve your desired flavour. The goal is to have most of the sugar gone, so it shouldn’t be super sweet. But it also shouldn’t be vinegary.
Don’t increase the size of your batch too quickly. I did and it resulted in a mouldy mess because the SCOBY wasn’t big enough to handle the sugar and keep the opportunistic microbes at bay. Start increasing slowly. Start with 1L, then do 1.5L, 2L, 3L etc. I now follow the exact ratio above, but for 4L at a time. It lasts 2 of us 2 weeks – and we each drink abut 4oz a day.
The SCOBY is a slimy mushroomy looking thing. But it’s not mould. Mould is very different. Here’s a good visual:
Your best bet is to get a piece of SCOBY from someone who has one going. Alternatively you can rehydrate one from a company like Cultures for Health. Apparently you can create a SCOBY by following the above process with a bottle of plain, store-bought kombucha too. But I’ve never done it, so you’ll want to google that!
You need to use sugar cane, not honey. Honey can introduce undesirable bacteria. Most of the sugar gets eaten up by the SCOBY.
If you let your ‘booch go too long, don’t throw it out. Instead turn it into jello jigglers – just make sure to add honey to combat the vinegary taste!
