The Link Between Gut Health and Inflammation

Don’t be so quick to dismiss buzzwords like ‘gut health’ and ‘good bacteria.’ The two – or lack thereof – have a direct connection to your body’s wellness.

Health buzzwords like “gut health” and “good bacteria” are thrown around all the time now, and for many, they often walk the line between seeming a little “out there” and overwhelming — a combination that can make you want to turn the page. But there’s legitimacy to maintaining a healthy gut, because it has a direct relationship to inflammation.

The Role of a Healthy Gut

Without sliding down a dark hole of complex microbe-gut talk, let me share the basics of the relationship. During digestion, foods are gradually broken down as they make their way through the gastrointestinal (GI) tract, with the goal being to dismantle the food into single nutrients or components small enough to be absorbed through the intestinal walls and into the body. It’s the variety of good bacteria that largely determine gut permeability — the level to which the nutrients in foods, as well as foreign bodies and irritants, can enter or “leak” into the bloodstream.

Healthy Gut: 

  • An intestinal tract with a variety of plentiful good bacteria provides a strong, fairly impermeable barrier in the lining of the intestines.
  • The strong microbe barrier allows digested nutrients to pass through, but prevents — or greatly limits — foreign compounds (toxins, chemicals, bad bacteria, etc.) and waste products from escaping into the rest of the body.

Not-So-Healthy Guts:

  • An intestinal tract where the good bacteria have been reduced or the balance disrupted (a state called dysbiosis) provides a weakened, much more permeable barrier with holes or gaps in the intestinal lining.
  • The weaker, fairly permeable microbe barrier allows digested nutrition to pass through, but also allows foreign bodies and waste components to cross the intestinal walls into the rest of the body as well. 
  • Research suggests that it’s “leaking” of foreign bodies and waste from the gut into the body that augments or encourages inflammation and initiates or worsens symptoms and diseases. 

The Influence of Diet on Gut Health

While there are still many unknowns, research suggests that there are key components in the typical American diet—too many added sugars, saturated fats, and processed foods, and too little fiber — that are largely responsible for disrupting gut health. What appears to restore or maintain the gut is a diet consisting of less-processed, whole foods with plenty of fiber-rich fruits and vegetables, as well as foods that either contain “good” bacteria or support their growth.
