How taking probiotics can prevent intestinal parasites

  • Probiotics 101

  • By Desiree Nielsen, Registered Dietitian

    Even as you sleep, your gut microbiome is always working for you: creating vitamins, modulating your immune system, and fighting off potential infections – including intestinal parasites.

    Parasite infection is more common than you think: if you’ve ever known someone who came down with beaver fever after a week at the cottage, you’ve encountered parasites. Giardia, the parasite that causes beaver fever, can cause infection after consuming untreated lake water; symptoms such as diarrhea, cramping and fatigue usually show up two weeks post-exposure.

    Pinworm is another common parasite that can be very persistent: the intestinal worms lay eggs around the anus that can live on skin or surfaces for up to two weeks. Another common and interestingly controversial gut parasite is blastocystis hominis. 

    There is so much we don’t know about this organism, including how it spreads – although it is thought that daycare environments and exposure to animals may increase risk. It is also found in the guts of those without symptoms, leading researchers to question whether the bloating, diarrhea or constipation that is attributed to blastocystis hominis is in fact caused by another organism3.

     

    Bacteria vs Parasites

    When you’re exposed to these parasites, is infection inevitable? It would appear that it depends on your microbiome. For example, helminths were once common in the human microbiome but are now rarely seen – and some researchers believe that without them, our immune systems are more hyper-reactive1.

    Likewise, exposure to giardia doesn’t always cause symptomatic infection1. While much is still unknown, it is thought that the ability of gut microbes to strengthen the mucus barrier of the gut helps prevent parasites like intestinal worms from causing parasitic infection or gut infection1.

    Lab studies also suggest that gut bacteria excrete substances that kill parasites, along with allowing your body to work more efficiently to kill parasites as well as providing competition for space and resources1,3. In fact, in one human trial, there was noted similarities in the gut microbiota of people with parasitic infection – even if they lived in different regions2

    Similarly, despite living in regions far apart, the guts of those who were able to fight off intestinal parasite infection showed similar microbes2.

    Early laboratory trials suggest that probiotic bacteria may help reduce risk of, and assist in fighting off, some parasitic infections3. It has been shown that certain dietary probiotics can help get rid of potentially infectious organisms, while strengthening the mucus barrier of the gut and supporting our immune defenses3.

     

    Strength in Numbers

    While the research is underway, there is no harm in aiming to strengthen your intestinal microbiome now. A healthy gut microbiome is a diverse one.

    To get there, you need to build the right environment. A clinical strength probiotic, such as Bio-K+, helps to foster a favorable and balanced microbial community – in fact, you may not know this, but taking a probiotics for intestinal parasites doesn’t just add beneficial bacteria to your gut, it helps foster the growth of the beneficial bacteria and gut flora you already have3.

    And once those good bacteria are in place, you need to feed them well. Our modern diets, low in fibre and high in salt, sugar and fat tend to have a negative effect on our gut microbiomes, encouraging the growth of more pro-inflammatory strains such as certain E.coli strains. Eating a variety of high fiber plant foods such as vegetables, whole grains and legumes provide non-digestible carbohydrates that drive fermentation and keep your gut microbes happily fed.

    Prevent Parasite Infection

    Intestinal parasite infection is more common than you think; if you are experiencing symptoms such as watery diarrhea, cramping or severe bloating, don’t wait. Go see your doctor right away. Of course, an ounce of prevention is worth a pound of cure. When you’re feeling well, help strengthen your defenses by eating well and taking a daily dose of Bio-K+ probiotic drinks or capsules.
