3 Ways Sugar & Artificial Sweeteners Affect Gut Health

Written by Dr. Group, DC Founder
A jar full of sugar. Sugar and artificial sweeteners can affect your gut health in a negative way.

Right now, your gut is swimming with bacteria — good and bad. Maintaining a good balance between the two is key to helping you stay healthy. One of the ways to support that is to give your gut flora supportive food, not detrimental. Sugar and artificial sweeteners can affect your gut health in some not-so-friendly ways. You probably have heard about the artificial sweeteners aspartame, saccharin, and sucralose — three of the biggest offenders — but can also add sugar to that list.

Shocking Facts about Artificial Sweeteners & Your Gut

Here’s a rundown of three concerns artificial sweeteners could cause.

1. Fake Sweeteners Cause Glucose Intolerance

One study suggests popular sucralose-based sweeteners can decrease good bacteria levels in the gut.[1] But it’s not just sucralose; other studies suggest all artificial sweeteners can actually influence the microbiota (your gut’s bacteria). This loss of good bacteria can lead to glucose intolerance, something that could lead to diabetes.[2]

2. Artificial Sweeteners Lead to Weight Gain

If you’re using artificial sweeteners and sugar, you might want to know that a recent report suggests fake sweeteners can actually change the way your body processes sugar. Yes, while this could raise blood sugar, leading to a bigger issue like diabetes, weight gain is also an outcome. Because these sweeteners contain no calories, they’re not digested, but they still have to travel through the gut. While there, they “may favor the growth of bacteria that make more calories available to us, calories that can then find their way to our hips, thighs, and midriffs.” [3]

3. Sugar Damages Your Gut Flora

Sugar can also promote the growth of bad bacteria in the gut.[4] This could lead to irritation in the gut, which could even manifest itself as an autoimmune response — like allergies or skin conditions. There’s even recent evidence suggesting depression is actually your body’s response to swelling in the gut.[5]

Restoring the Health of Your Gut

While the best thing you can do is cut sugar and artificial sweeteners out of your life altogether, that probably isn’t practical advice for most people. A more achievable goal is to reduce the number of sweets you eat as much as possible, and further support your gut health with a quality probiotic.
