Low-Fiber Diet Gradually Depletes Good Bacteria In The Gut: How This Can Affect Overall Health


The bacteria we have inside our body aren’t all bad. For instance, good bacteria or probiotics in our stomach help the body digest food and fight against invading microbes.

Probiotics can be found in dairy products such as yogurt and in other dietary supplements. A previous study conducted by Lund University has even discovered that a glass of water contains about 10 million good bacteria. These probiotics are significantly vital to our mental and physical health.

Now, new research suggests that a low-fiber diet may be posing a threat to these essential microbes. This could someday result in internal deficiencies that are passed down over generations, experts said.

A Low-Fiber Diet Depletes Gut Microbes

Researchers from Stanford University School of Medicine found that Western diets – food rich in fat, sugar and cholesterol but low in fiber – may be gradually depleting probiotics over time.

Unfortunately, about 90 percent of people in the United States admit to eating too much salty food from the Western diet.

Along with that, obesity and diabetes rates in the country are skyrocketing every year. According to the World Obesity Federation, about 2.7 billion adults will become obese worldwide by 2025.

The obesity epidemic in the U.S. can be blamed to poor diet, low physical activity and increasing sedentary behavior, experts said. The Stanford study builds upon this notion.

Gut Bacteria In Mice

In a study featured in the journal Nature, the team examined mice that had been raised without access to normal nutrient-rich food. The gut bacteria in these mice were found to have depleted entirely.

Led by Associate Professor Justin Sonnenburg, the team inserted human gut bacteria into lab mice to recreate the lost microbiomes. They divided the mice into two groups: the first would eat a diet rich in fiber, while the second would eat a no-fiber diet.
