10 Foods That Are Probably Making You Bloated (And What to Eat Instead)

One of the first things I tell new clients is this: bloating is not about eating unhealthy food. Some of the most nutritious foods in the world are major bloating triggers for people with IBS or SIBO. It has nothing to do with how "clean" your diet is.

It has everything to do with FODMAPs — fermentable carbohydrates that your gut bacteria love to feast on. When those carbs reach your small intestine undigested, bacteria ferment them and produce gas. That gas is your bloating.

Here are ten foods that are very commonly the culprit — and what to reach for instead.

1. Garlic and Onions

These are the number one offenders I see, and they're hiding in almost everything — restaurant sauces, packaged foods, soups, dressings, marinades. They're extremely high in fructans, a type of FODMAP that a lot of people with IBS simply cannot tolerate. The good news? Garlic-infused oil gives you all the flavor without the fructans — they don't transfer to the oil. Green scallion tops and chives are great swaps too.

2. Wheat-Based Products

Here's something that surprises almost everyone: for most people with IBS, the issue with wheat isn't gluten — it's fructans. Bread, pasta, crackers, flour tortillas. If you've gone gluten-free and felt better, fructans were probably why. Try sourdough (fermentation reduces the FODMAP content significantly), rice, quinoa, or certified low-FODMAP breads.

3. Apples and Pears

They feel like the healthiest snack you could possibly choose. But they're high in excess fructose and polyols — two major triggers. Swap them for oranges, strawberries, grapes, or kiwi. Just as satisfying, much kinder to your gut.

4. Milk and Soft Cheeses

Lactose is the issue here. Hard cheeses like cheddar and parmesan are naturally very low in lactose and usually well-tolerated. Lactose-free milk is a seamless swap. Many of my clients are genuinely shocked by how much better they feel once lactose is off the table.

5. Beans and Lentils

High in galacto-oligosaccharides (GOS), which are well-known gas producers. That said, canned and well-rinsed lentils in small portions are often tolerated. Firm tofu and eggs are excellent high-protein alternatives.

6. Cauliflower and Mushrooms

Both contain mannitol — a polyol that commonly causes bloating and diarrhea. Cauliflower in particular has become such a staple of "healthy eating" that people are genuinely caught off guard when I flag it. Zucchini, bell peppers, carrots, and bok choy are delicious swaps that won't leave you miserable.

7. Honey and Agave

Both are high in excess fructose. Maple syrup and regular table sugar in moderation are actually better tolerated by most people with IBS. Stevia works too.

8. Dried Fruits

The drying process concentrates the fructose — a small handful of dates or raisins can be enough to trigger significant symptoms. Stick with fresh fruit in appropriate portions.

9. Sugar-Free Gum and Mints

I talk about this constantly because it flies under the radar. Sorbitol, mannitol, xylitol — these sugar alcohols are notorious gut irritants. And you're swallowing extra air every time you chew. It's a double hit. Ditch the gum.

10. Artichokes and Asparagus

Both are high in fructans. I know — delicious and nutritious. Green beans, spinach, and cucumber are great swaps that won't set you back.

One thing I really want you to understand.

This is not a permanent "never eat these foods again" list. The low-FODMAP diet is a structured elimination and reintroduction process — not a life sentence. The whole point of reintroduction is to figure out YOUR specific triggers so you end up with the least restrictive diet possible.

Most of my clients end up tolerating many of these foods once their gut has healed. The goal is always to get you eating as broadly and freely as possible — with a body that actually cooperates.

If you want someone to walk you through this properly, that's exactly what I do.
