Previously, I wrote a post about gut health and allergies. In that post, I mentioned a study conducted in Sweden highlighting the benefits of having a diverse bacterial ecosystem in the gut to help protect against future allergies and conditions, including eczema.

The Importance of a Diverse Gut Ecosystem

Strong and diverse gut health does more than protect against allergies. It is also crucial for babies when it comes to colic. Colic is believed to affect as many as 1/3 of all babies. There does not appear to be a difference between those babies that are breastfed and those that are bottle-fed.

There are many different theories as to the cause of colic, and it's important to note that no one knows for certain. Given that we are bio-individual creatures, it's likely that there are multiple reasons. Dietarily, there appears to be some success for a large number of babies when lactose (milk sugar) is removed from their diet.

These babies have what is referred to as lactose overload, or functional lactase insufficiency. In plain English, they are not producing enough lactase (the enzyme which breaks down lactose), and this causes gastric distress. This is not lactose intolerance, but rather the undeveloped digestive system not having enough lactase; this situation does correct itself over time.

Gut Health and Colic

Over the past few years, the health of the intestinal ecosystem has come under scrutiny as a possible reason for colic.

Back in 2009, researchers at the Texas Health Science Center (THSC) in Houston found a connection between gut health and colic. The study seemed to indicate a correlation between bacterial balance and colic. Although the initial study was small, all the colicky infants tested positive for Klebsiella, a bacteria often found in the mouth and intestines of adults.

The study concluded, "Infants with colic, a condition previously believed to be nonorganic in nature, have evidence of intestinal neutrophilic infiltration and a less diverse fecal microflora." (The less diverse microflora theory was shown to be true in the Sweden study mentioned above.)

Benefits of Probiotics

Now another study, published in the journal BMC Microbiology in June 2011, appears to show positive results for inoculating with beneficial bacteria, such as lactobacillus.

In this study, two strains of lactobacillus had positive antimicrobial effects. Studies are continuing to see which strains are best; I assume the studies will also look at how to best deliver probiotics to the infant without overwhelming their system.

I know many mothers add higher levels of probiotic foods to their diet to help their immune systems be as strong as possible. I also know some mothers who have used liquid probiotics and put it on their nipples just before breastfeeding to help the infant get some beneficial effect. If you feel it would be beneficial to add probiotics to the diet of your infant child, it's important to let your healthcare professional know. If you are working with a lactation specialist, let them know as well.

The Mother's Gut Health

One thing that neither of these studies addresses is the gut health of the mother. As I've mentioned before, Dr. Natasha Campbell-McBride points out that most gut disturbances tend to be generational disorders.

It is highly beneficial for the mother to have a strong bacterial ecosystem; this is what gets passed along to the infant and what helps to inoculate them during a natural birthing process.

For all of us, having a strong, diverse, healthy gut is important to health. Now it looks like it's even more important to support the health of future generations.
