Guest Post, The Paleo Mom: Gut Health For Kids

Today’s guest post (we’re a day late, sorry!) is by our favorite scientist, The Paleo Mom! In the wake of Stacy’s diet changes of late, we’ve been getting lots of questions about gut health and what foods to eat, especially for children. This post should answer many of your questions and help you set up your child for a life of good digestive health!

Gut health is essential for overall health.  A healthy digestive tract is efficient at absorbing nutrients from your food, protecting the body from foreign invaders including mounting appropriate immune responses when required, and at regulating a wide variety of hormones.  A growing number of health conditions are being linked to poor intestinal health.  As you already know, the foods you eat can have a powerful influence on your gut health (for more information on how grains, legumes and dairy contribute to a leaky gut, read this post, this post, and this post). 

So, what about kids?

A paleo diet is a fantastically healthy diet for kids, as we consume only the most nutritionally-dense foods (I am very fond of the nutritional analysis presented in
The Paleo Diet).  It is also a great starting place if your child requires a focus on healing the gut.

Many of the recommendations for optimizing adult gut health (as outlined in here and here) are appropriate for babies and younger children. However, getting a child to eat what you know is good for them can be a challenge!  Also, many of the supplements recommended to promote healthy digestion are inappropriate for children (such as digestive enzyme, hydrochloric acid, and apple cider vinegar supplementation; other supplements such as L-glutamine and quercitin should only be given to your child under the supervision of a medical professional).  So what can you do to help them?  Whether you are looking for strategies to heal your child’s confirmed or suspected leaky gut or are looking for ways to protect your healthy child from developing a leaky gut, here are some ideas for promoting a healthy gut for your child (including some practical tips for pulling it off!).

1. Start Them Off Right:

Breastfeeding your baby is the best way to ensure that their digestive tracts develop a healthy diversity of beneficial bacteria.  However, if you face insurmountable obstacles to breastfeeding or have gut dysbiosis yourself (or if your child requires antibiotic treatment), you may want to supplement with a source probiotics to help their digestive tracts establish this essential probiotic diversity.  I chose to supplement with a small amount of acidophilus for a couple of months before starting my youngest on solid foods (I didn’t know any better for my oldest and I still regret it).  I bought acidophilus/bifidus supplements in capsule form, broke open the capsules and put a tiny pinch of the powder in her mouth before nursing a couple of times a day, starting at about 3 months old.  I bought the highest diversity/quality probiotic supplement I could find and changed brands every time I bought a new bottle (I was taking it for myself at the time, so I went through a small bottle fairly frequently).

Other people achieve the same using fermented foods (for a baby or toddler who can’t chew raw sauerkraut, a little of the “juice” around the sauerkraut can be given on a spoon or mixed in with other foods). It also helps not to start solid foods too early (typically, the digestive tract isn’t really ready for solids until about 6 months old).

I am a big fan of “baby-led weaning” which essentially means that you don’t start your baby on solids until they are ready to self-feed.  For both of my girls, that was around 7 months old (they could pick up small pieces of cooked vegetable or soft fruit, put it in their own mouths, chew and swallow), but many babies aren’t ready until older than this, and that’s okay!  If you are wondering what foods to introduce first, check out my post on paleo baby foods (this post is written for traditional introduction of solid foods, but the information is also relevant to baby-led weaning).  Don’t worry if your child is older and you missed your chance, because you can still…

2. Sneak Some Probiotics Into Their Diet:

Even after your child is eating solids, a continuous supply of good bacteria and yeast in their diet is good for them, especially if you are trying to restore gut microflora diversity after illness.  You can introduce these in the form of kombucha, yogurt and kefir (I’m a big fan of homemade coconut milk yogurt and kefir), fermented vegetables like raw sauerkraut and homemade pickles, and/or acidophilus supplements (you can continue to break open acidophilus capsules or switch to chewable tablets once your child is old enough).

Frequent small doses are more effective than one large dose, so 1 Tbsp of homemade kombucha or coconut milk kefir mixed in with your child’s food or beverage daily is a great way to go (do keep in mind that regular kombucha does have a small amount caffeine).

This is especially important after any infection requiring antibiotics or steroids and after stomach bugs.  Is this important to do if your child is healthy and you are just looking to prevent problems?  The answer is yes and no.  If your child is healthy now, they almost certainly have a healthy diversity of bacteria growing inside them now. There is no added benefit to including a probiotic supplement in their diet. Fermented foods however, are still beneficial as these help feed the good bacteria growing in their guts in addition to adding a much greater variety of beneficial bacteria than typically found in supplements.

3. Include some healing foods in their diet.

Homemade bone broth is rich in glycine, which is very important for healing the lining of the gut and reducing inflammation (for more information, see this post).  My 2.5-year old loves to drink plain bone broth, but it can also be added to mashed vegetables, smoothies and even homemade popsicles!

Organ meats like liver (especially if grass-fed) contain Vitamin D, tons of vitamin and minerals, and more glycine than muscle meat.  Just because you don’t love liver, doesn’t mean your child won’t.  It’s a soft meat and many young kids find the texture more enjoyable than muscle meats.  If your child isn’t a big fan, check out my recipes for hidden-liver meatloaf and hidden-liver Turkish meatballs.

Oily cold-water fish is not only rich in omega-3 fatty acids (the highest omega-3 fish are salmon, mackerel, sardines, herring, kipper, anchovies, trout, fresh tuna, and carp) which helps resolve inflammation, but is also high in vitamin D and selenium.  My 2.5-year old loves brisling sardines and both my kids love poached or baked salmon.  There are dozens of neat seafood recipes out there, from salmon cakes to fish sticks (which could be made with haddock, cod, hake, halibut, sole, flounder, bass or perch which are all moderately high in omega-3), which may entice your child to eat them.

The medium chain triglycerides (MCTs) in coconut oil are known to have anti-microbial and anti-inflammatory properties. Extra virgin coconut oil also contains a large amount of Vitamin E and other anti-oxidants and is wonderful for cooking just about anything, from paleo baking to scrambled eggs (or even just eating off a spoon!).  Coconut butter can be eaten by the spoonful or added to soups and curry dishes. Full-fat coconut milk (which can be easily made at home) can be added to smoothies or used to make homemade kefir or yogurt.

Grass-fed meat (and butter and ghee from grass-fed diary) is rich in conjugated linoleic acid (CLA), a fat known to promote healing, as well as providing plenty of vitamins, minerals and having a balanced omega-3 to omega-6 ratio.  My kids love anything made with ground beef, from Swedish meatballs to tacos!

4. Avoid gut irritating foods, including foods you child has a sensitivity to:

Avoiding grains, legumes, dairy, processed foods and refined sugar will go a long way to improving your child’s gut health.  However, if your child is facing an uphill battle with health, there are some other culprit foods worth eliminating as well.

If your child has signs of Small Intestinal Bacterial Overgrowth (SIBO), youÆll want to limit starchy vegetables (see this post for a guide on which vegetables are okay for SIBO and which are better to avoid).  Another class of vegetables that can cause issues for some people are those high in types of sugar that qualify as FODMAPs (Fermentable, Oligo-, Di-, Mono-saccharides and Polyols). Continued digestive symptoms after following a paleo diet may indicate SIBO or FODMAP-sensitivity (also known as fructose malabsorption).  There is a high degree of overlap between vegetables that are avoided to address SIBO and those that contain FODMAPs.

If you aren’t sure, try an elimination diet approach where you avoid all vegetables which may be problematic for 3-4 weeks and then slowly try reintroducing them one at a time to see if they cause digestive symptoms. In addition to these vegetables, other foods may be problematic due to development of food sensitivities (this is common in children and adults with severely leaky guts).  You can evaluate whether or not these foods are problematic for your child using an elimination diet approach (where you leave the suspected foods out of your child’s diet for 3-4 weeks and then add them back in one at a time).

Sensitivities to eggs, nuts, seeds, and vegetables from the nightshade family (tomatoes, eggplants and peppers) are common.  Alternatively, you can find a naturopathic physician or chiropractor who can order a food sensitivity blood test (IgG and IgA).  Any foods that your child tests positive for in a food sensitivity test should be avoided completely for at least 6 months, after which you can reintroduce small amounts to see if the sensitivity persists (many sensitivities will disappear after the gut has fully healed).

5. Play and Have Fun:

Kids need both structured and unstructured play time, both active play and quite, focused play time, and both independent and social play time (with other kids and/or with adults).  Having this mix of different types of play is important for the developing brain, but also helps regulate hormones (like stress hormones, which are particularly important to gut health) and helps tire kids out for a good nap and a good night’s sleep (also critical for healing and staying healthy).  And making sure to take time to have fun with your kids is good for your stress levels too!

6. Get them outside:

If you read my post on the importance of sunlight, you’ll remember just how important it is to be outside for a good amount of time every day.  For kids, it also provides space to run around and a stimulating environment for their developing brains to explore (you get to play and get sun exposure! Yay for efficiency!).

I aim to have my kids outside for at least 1-3 hours every day, weather permitting (I am a big supporter of playing outside in just about any weather as long as you’re dressed for it!).  Beyond the benefits of fresh air and exercise, sun exposure on their skin is essential for the formation of Vitamin D (you don’t want to let them get sunburned, of course).  Vitamin D is very important for healing and reducing inflammation. If getting outside is not possible for you and/or your child or if you feel that your child may deficient in Vitamin D, it is worth talking to your doctor about a Vitamin D3 supplement.

7. Provide an environment conducive to sleep:

Sleep can be more or less of a challenge depending on your child.  One book that I really like for gentle sleep strategies for babies is The No-Cry Sleep Solution (also available in a toddler through preschooler edition).  The tips that have been most helpful for me and both of my non-sleepers are:  have a rock-solid routine (not just at bedtime but consistent structure throughout the day), put your kids to bed earlier rather than later (they will often sleep longer if they go to bed earlier), and have kids sleep in a cool, very dark room.  A white noise machine may also be helpful.

8. Don’t make food a battle:

However you chose to introduce food to your child, whether or not you chose to give your child options or only give them what everyone else is eating, don’t make meals a battle.  This means having a realistic expectation of what and how much your child might eat, of how long they might sit up at the table, and of age-appropriate table manners.

Even if you are taking a firm stance, don’t argue or raise your voice.  Stress and food just don’t mix.  And stress can hinder healing.  Keep in mind that, when given a variety of healthy foods, the vast majority of children will naturally eat what their bodies need.

The two most important things that you can do to help your child learn how to eat healthily is do so yourself and present them only with healthy options.

As a final thought, I believe you are already doing the most important thing you can to help your child get/stay healthy by learning about how food affects the human body.  If you are unsure how to apply any of these recommendations or whether they are appropriate for your child, please discuss them with your child’s doctor or alternative healthcare provider.
