Foods That Are Secretly Causing Your Bloating
13. Cruciferous Vegetables (Cooked, Large Portions): Beyond Raw's Gas

Even when cooked, large portions of cruciferous vegetables like cabbage, broccoli, or Brussels sprouts can still be a secret source of bloating for sensitive individuals. While cooking breaks down some compounds, these vegetables remain rich in unique sulfur-containing compounds and complex sugars (raffinose, stachyose) that require specific enzymes for digestion. When these aren't fully broken down, they ferment in the large intestine, leading to persistent gas and abdominal distension, even from seemingly "healthy" cooked dishes.
14. Oats (Specific Types & Quantities): The Soluble Fiber Surprise

While steel-cut oats are celebrated for their soluble fiber, a rapid increase in any type of oat consumption, especially highly processed instant oats, can be a surprising bloat culprit. The soluble fiber forms a gel that can be difficult for some guts to process quickly, leading to fermentation and gas. For sensitive individuals, even the beneficial beta-glucans in oats can overwhelm the system. Gradual introduction and adequate hydration are key to harnessing oat's benefits without the uncomfortable bloating.
