Unexpected Foods That Can Wreck Your Digestive System

21. Excessive Raw Vegetables: A Fiber Overload

Raw veggies are healthy, but for those with compromised digestion or conditions like IBS, consuming too many raw cruciferous vegetables (like broccoli, cauliflower, or cabbage) can lead to gas, bloating, and discomfort. The high fiber content and natural plant compounds (like goitrogens and FODMAPs) can overwhelm a struggling digestive system. Lightly steaming or roasting these vegetables makes them easier to digest while still preserving nutrients.

22. Overuse of Antibacterial Mouthwash: A Surprising Gut Disruptor

The gut microbiome doesn’t start in your stomach—it begins in your mouth. Overusing antiseptic mouthwashes like chlorhexidine can kill not only bad oral bacteria but also beneficial ones that support nitric oxide production and downstream digestion. This microbial imbalance can affect the entire gut ecosystem. Consider switching to alcohol-free or microbiome-friendly oral care products, and use mouthwash in moderation.
