The Bugs In Your Body

Mar 12, 2010 BY Joy McCarthy

Did you know that your digestive system is home to more than one hundred trillion bacteria. Yes you read that correct - 1,000,000,000,000 creepy crawlies found primarily in your small intestine and colon (oh and a few BILLION in your mouth). In fact, you have more bacteria in your gut, than cells in your entire body. According to Elizabeth Lipski, Ph.D., and author of "Digestive Wellness" the dry weight of your stool is comprised of 80% bacteria and a whopping 50% of it is still alive. The balance of good vs bad bacteria is absolutely critical for health and they do a heck of a lot more than just give you the heebeejeebees. I know I got a little itchy when I first wrote this article too. :)

What do these trillions of bacteria do?

These bacteria are a hot topic in the news and there's no shortage of products popping up everywhere on store shelves with added "bacteria". The bacteria does an absolutely incredible job at keeping us healthy, but can also have a negative effect too,  if the bad guys get out of hand. So what's all the fuss about? Bacteria does all this and more:

Keep our immune system strong and play a very important role in our ability to fight infectious disease

Affect our nutritional status - absorption of minerals/manufacture of vitamins

Friendly bacteria actually make: biotin, B1, B2, B3, B5, B6, B12, folic acid and vitamin K

And they increase absorption of calcium, copper, iron, magnesium and manganese

Manufacture substances that raise and lower our risk of disease and cancer

Impact the effect of drugs

Impact our rate of aging - whoa! I bet you are thinking about that organic yogurt now?

Some of these bacteria can cause acute or chronic disease

And some can cause serious illness in people who are more genetically susceptible, but no problems in other people

Help us increase our resistance to food poisoning

Improve digestive health: inflammatory bowel diseases (IBS), constipation, diarrhea etc

Help us digest lactose. This is why some people can tolerate yogurt but not milk, for the simple reason that there is more good bacteria in yogurt

Beneficial in treating: vaginal yeast infections, thrush, urinary tract infections, arthritis, cholesterol

I could list more reasons, but I think you get the point, they are important for a healthy body, not just a happy colon

Where did these creepy crawlies come from?

The two most important groups of flora are the lactobacilli (I just love saying that word aloud) found in the small intestine and bifidobacterium (say that 5 x fast), found primarily in the colon. Here's the deal: we are literally born with a sterile digestive tract. We are then exposed to good bacteria in breast milk and with every breath and touch, bacteria enter the body to colonize and make a cozy home. Within the first few days of life, we are home to hundreds of bacteria and breast-fed babies have increased numbers of lactobacillus and bifidobacteria species from mama - yet another reason to breast feed your bebe. Often times when babies are unable to properly colonize the friendly bacteria they become irritable, colicky, have gas and even eczema on their bottom. They are also more susceptible to allergies and asthma according to Elizabeth Lipski, Ph.D.

Not all the creepy crawlies want to make us healthy.

Unfortunately, the friendly bacteria only comprise a very small percentage of our total bacteria. Most disease causing bacteria thrive at human body temperature, while a fever kills them by overheating your body. Don't you just love how smart your body is? If you have a sudden invasion of salmonella your body reacts quickly by saying "GET THIS OUT OF HERE IMMEDIATELY", and you get a bout of diarrhea or vomiting. Be thankful for this response, I cringe at the thought of people taking diarrhea suppressing drugs when they have food poisoning, as this could lead to more health complications later on down the road. The last thing you want to do is plug up that bad bacteria.

How do you balance your gut with more good than bad?

You eat them, avoid processed foods and take a good quality supplement. As a nutritionist, this is the sort of thing I teach people everyday in my practice - what foods to eat to increase friendly bacteria and what supplements are best. Here's a great article on my favourite bacteria rich food: http://joyoushealth.wordpress.com/2010/01/04/kefir-is-a-super-food/

There is an array of probiotic supplements on the market and believe me, some of them I wouldn't touch with a 10 ft pole. I prefer to use only professional lines that can be purchased from a certified Nutritionist or N.D. because they are batch tested, adhere to strict regulations and grow and source their bacteria from reputable companies. I once had a client come to me with very poor gut health and serious digestive problems. She was taking a very cheap brand of probiotics and as soon as I switched her to a reputable brand, her symptoms went away. Here's the thing, every person has slightly different needs, nutritional status/deficiencies, age impacts what you should and should not take and therefore, it is absolutely critical to speak with a certified nutritionist to find out what your needs are. You may not need to take a $120 bottle of probiotics, but you might need to make some dietary changes and take a $30 bottle of acidophilus.

As Dr. Bernard Jensen has stated many times in his books, the gut is really the root cause of disease. Keeping your gut healthy with good bacteria is absolutely critical to the health of your whole body. I'm not saying that probiotics solve every problem, but they are certainly one of the most basic supplements that every person should be taking.

Thanks for your comment Marci. I'm actually going to write an article about this next week. Stay tuned :)

Great article Joy! I agree 100%. The more people realize the importance of their gut health, the healthier everyone will be.

Awesome article. When I first started breastfeeding my first I knew it was healthier but didn't really understand why and I had a bunch of moms telling me that formula was just as good and I had nothing to say back. Now that I've been breastfeeding for nearly 1.5 years collectively I have so many things to say back(too bad no one says it to me anymore, haha). Anyone that says it's just as good is ignorant. I don't take a supplement(although I do eat a good amount of yogurt) but I think I will consider it. It bothers me too when I hear of people trying to stop their symptoms when it's just their body doing its job! I know I said it before, but I reeeaaaally enjoy your site :)

You are absolutely right Heidi, there is nothing on planet earth as nutritious for a baby, as a mom's milk. And yes, I totally agree, symptoms are simply your body's sign that an imbalance exists. Society has become so accustomed to just popping pills to make symptoms go away. Thank for your nice compliment, it is always wonderful to hear that people are getting something out of these articles. Take care Heidi, Joy

Probiotic and Prebiotic. Which is the best ? Both these supplements often you hear as a supplement that helps maintain the health of your digestive tract. Both these supplements are also available in a variety of dairy products, beverages, and food which good for you or your baby. It's not important supplements? So which one is better, pre-biotic or pro-biotic? Before discussing further, of course you have to know what pre-biotic or pro-biotic is?

Both are important. Prebiotic is needed for the probiotic to work. Think of the prebiotic as the soil that the probiotic grows in. Many probiotic supplements have a prebiotic fibre in the capsule already. Yes there are some prebiotic foods like yogurt, kefir and other fermented foods which you will find bacteria in the millions. However if you want a therapeutic dose in the billions, then a supplement is the only way to obtain this - diet alone will not achieve this.

Yes, both are important. But according to a reliable source, probiotics are better than the prebiotic. You can see an explanation about this on this site. http://www.nutrition-for-health.net/supplement/ProbioticAndPrebiotic.html

Wow, this gave me the chills for a second in a gross yet fascinating way! Very interesting. Could I ask is there a probiotic brand you recommend that can be found in the US? I remember one of your videos a while back mentioned HMF Forte which I could not find at Whole Foods, Vitamin Shoppe, or practically any health store in my neighborhood.

hi joy, this is such a fabulous article. i have a question...not sure if your can answer or not...can probiotics wipe out estrogen? i love & have been taking hmf forte probiotics for a while, but can't take them everyday. if i do, i don't get my period! so, i take them about 3 times a week. i'd love to be able to take everyday though to get the full benefit, as i feel so much better taking them everyday.

Hi Marissa, No probiotics cannot wipe out estrogen but they can certainly aid the body in detoxification. Therefore if you have an excess of estrogens, then taking a high quality probiotic will help your digestive system which in turn can help elimination of harmful and excess hormones. I have never heard of someone not getting their period. Could there be something else going on?
