Gut Check: Digestive Health Boosts Your Immune System

GettyImages-997808980Fall is here and winter is nearly upon us, and that means that cold and flu season have also arrived. Have you noticed that some people just don’t get sick no matter what? Or maybe you have wondered why after being exposed to the same virus, one person gets sick while the other doesn’t.

The answer to that lies in your immune system and how strong it is. When you are exposed to bad bacteria or viruses, it’s up to your immune system to protect you from being infected. If your immune system is strong, your body will fight off the threat of sickness. If you have a weak or compromised immune system, you may end up sick. What you might be surprised to learn is this: The strength of your immune system is highly dependent on the condition of your digestive system.

The Good, the Bad, and the Ugly: Let’s Talk Microbes

Microbes live inside your digestive system. They are living organisms that affect your overall health. The protection that some of these organisms provide is beneficial to your immune system. The good bacteria recognize when illness-producing intruders enter your body; the organisms attack the intruders so that you don’t get sick. If you don’t have enough of the good bacteria in your gut, you will be more susceptible to viruses like colds and stomach viruses. You also may be at more risk for autoimmune diseases such as colitis, rheumatoid arthritis, and Crohn’s disease.

Although there is a large supply of these good microbes living in your gut, they can easily become diminished. If you have recently taken antibiotics, you have not only wiped out the bad bacteria, but also the good bacteria. Antibiotics are not selective in their destruction.

With that being said, antibiotics are not the only way that good bacteria becomes exhausted in your digestive system. For example, the chlorine in your drinking water can destroy them, as can the pesticide residue on the food that you eat.

Once the supply of helpful microbes in your intestines dwindles, bad microbes such as yeast, fungi, and disease-causing bacteria begin to take over. Immune systems become compromised when the bad takes over the good.

Cue the Probiotics

If you think that your good microbes might be minimal, it is not difficult to remedy the problem. The solution is to take probiotics. These are the good microbes that you can consume in your diet. Once they have entered into your body, they settle in your digestive system and get to work protecting you from sickness and destroying the bad bacteria that might reside there.

The option of consuming probiotics in a capsule form is there, but you can also replenish the good microbes by eating yogurt. Check the label to be sure that the yogurt you buy says that it contains active cultures, which is the good bacteria that you need to eat.

It is important to act now and get a jump on this year’s cold and flu season. Improve your gut function and fight off illnesses by getting ahead of the game.
