5 Snacks That Damage Gut Health: Gastroenterologists Warning to Avoid Immediately

To have a healthy gut, take a close look at five harmful snacks that damage the gut microbiota, with advice from a gastroenterology specialist for a balanced digestive system.

"A healthy gut means good overall health." This phrase is not an exaggeration, as the gut is often considered the body's second brain. But did you know that your snacking habits during the day might be unknowingly damaging your gut ecosystem? Today, Thairath Online explores expert recommendations from a gastroenterologist on which snacks to "say goodbye to" in order to restore gut health.

Why is gut health more important than you think?

Scientists have found that the microbiome, or gut microorganisms, play a crucial role in the immune system, mental health, and metabolism. Eating foods high in sugar or heavily processed can encourage harmful bacteria to grow and disrupt this balance, leading to symptoms like bloating, fatigue, and even chronic inflammation.

Five harmful snacks that gastroenterologists strongly advise to avoid.

1. Fried snack foods

Potato chips and most packaged fried snacks are loaded with trans fats and saturated fats, which are major contributors to gut inflammation. Doctors note these fats are hard to digest and interfere with the gut lining's function.

2. Sweets and candies

Refined sugar is a prime fuel source for harmful bacteria. Consuming large amounts of sugar can cause gut dysbiosis and negatively impact the growth of probiotics, the beneficial microbes.

3. Processed meats

Sausages, bologna, and dried meats that contain preservatives and high sodium are gut enemies. Research clearly shows these foods increase colorectal cancer risk and reduce microbial diversity.

4. Artificially sweetened beverages

Many choose zero-calorie sodas, but synthetic sweeteners like aspartame or saccharin may alter the gut microbiome structure, making the body more prone to insulin resistance.

5. Baked goods made from refined flour

Cakes, cookies, and donuts made with refined flour contain no fiber, which is the main food for beneficial microbes. Without fiber, gut motility slows and constipation can occur.

What should you choose instead for a healthy gut?

Doctors recommend that when feeling hungry between meals, opt for "real food" or natural snacks such as:

  • Plain yogurt: directly adds probiotics.
  • Nuts and whole grains: sources of fiber and good fats.
  • Fresh fruits: especially berries high in antioxidants.

Taking care of your gut health isn’t difficult. Start by observing what you consume during breaks. Avoid processed foods and choose high-fiber options. This not only improves digestion but also lays a solid foundation for long-term overall health from the inside out.
