Are Baked Beans Low FODMAP? Servings & Swaps 2025
Navigating a low FODMAP diet can feel like a minefield, especially when it comes to comfort foods like baked beans. You’re trying to manage your digestive symptoms, but the conflicting information and hidden ingredients in everyday foods make it a constant challenge. Are you supposed to give up this classic dish forever just to find relief?
No, traditional store-bought baked beans are generally considered high in FODMAPs and are not suitable for the elimination phase of the diet. This is primarily because they are made with navy beans and contain high-FODMAP additives like onion and garlic powder, which are major triggers for IBS symptoms.
But don’t lose hope. This isn’t the end of the road for your love of baked beans. Leveraging a deep analysis of food composition data and preparation techniques, this comprehensive guide will give you the clear, actionable answers you need. We’ll break down exactly why commercial baked beans are a problem, show you proven strategies to make beans more digestible, and even provide a delicious recipe so you can enjoy this comforting classic without the painful side effects.
Key Facts
- Primary Culprits: The main reason baked beans are high FODMAP is their content of Galacto-oligosaccharides (GOS) and fructans, two types of fermentable carbohydrates that can trigger digestive distress in sensitive individuals.
- Human Biology: Humans naturally lack the enzyme alpha-galactosidase, which is necessary to properly break down the GOS found in beans, leading to their fermentation in the large intestine.
- Preparation is Key: The FODMAP content in beans is significantly reduced through processing. Since FODMAPs are water-soluble, using canned and thoroughly rinsed beans can wash away a large portion of the symptom-causing compounds.
- Brand Warnings: Major brands like Bush’s and Heinz are not low FODMAP. Their recipes use high-FODMAP navy (haricot) beans and include other triggers like onion and garlic powder in their sauces.
- Portion Control is Non-Negotiable: Even “safe” beans are only low FODMAP in small, specific quantities. For example, Monash University data confirms that canned chickpeas are only low FODMAP at a serving size of ¼ cup (42g).

The Short Answer: Why Traditional Baked Beans Are High FODMAP
No, traditional baked beans are generally high in FODMAPs. This is due to their main ingredient, navy beans, and added flavorings like onion and garlic powder, which are high in fermentable carbohydrates called galacto-oligosaccharides (GOS) and fructans that can trigger IBS symptoms.
If you’ve ever felt that familiar bloating or discomfort after a meal of classic baked beans, you’re not imagining it. The very components that make up this beloved dish are a perfect storm for someone on a low FODMAP diet. A FODMAP is a type of short-chain carbohydrate that your small intestine has trouble absorbing, leading to fermentation by gut bacteria and the resulting gas, pain, and bloating. Traditional baked beans are loaded with two specific types.
The main culprits in baked beans are Galacto-oligosaccharides (GOS) from the navy beans themselves and fructans from common additives like onion and garlic.
So, does this mean baked beans are off the menu forever? Not necessarily. Let’s break down how you can still enjoy them.
Understanding the FODMAPs in Beans: GOS and Fructans Explained
Beans contain high levels of GOS and fructans, which are FODMAPs the human gut cannot break down. This leads to fermentation by gut bacteria, causing common IBS symptoms like gas and bloating.
To understand why your body reacts this way, you need to know what a FODMAP actually is. The acronym stands for:
- Fermentable
- Oligosaccharides (like GOS and Fructans)
- Disaccharides (like Lactose)
- Monosaccharides (like excess Fructose)
- And
- Polyols (like Sorbitol and Mannitol)
The “O” in FODMAP, oligosaccharides, is the category that beans fall into. Here’s the deal: to digest these specific carbohydrates, our bodies need a special enzyme called alpha-galactosidase. The problem? Humans don’t produce it. Without this enzyme, the GOS and fructans pass through the small intestine undigested and arrive in the large intestine, where they become a feast for your gut bacteria. This fermentation process releases gas, which leads to the painful bloating, cramping, and discomfort associated with IBS.
Quick Fact: Did you know? The FODMAPs in beans are water-soluble. This is a crucial piece of information we’ll use later to our advantage!
Brand Breakdown: Are Bush’s or Heinz Baked Beans Low FODMAP?
Popular brands like Bush’s and Heinz are high in FODMAPs. They use navy beans and add ingredients like onion and garlic powder, making them unsuitable for the elimination phase of the diet.
When you’re standing in the grocery aisle, it’s easy to wonder if one brand might be safer than another. Unfortunately, when it comes to the big names in baked beans, the answer is a clear no. We analyzed the typical ingredients in these popular products to give you a definitive verdict.
| Brand | Main Bean Type | High FODMAP Additives | Verdict |
|---|---|---|---|
| Bush’s Baked Beans | Navy Beans | Onion Powder, Garlic Powder | High FODMAP |
| Heinz Baked Beans | Haricot Beans (Navy) | Onion, Garlic Powder | High FODMAP |
Both brands use navy beans (also known as haricot beans), which are naturally high in GOS. To make matters worse, their signature sauces almost always contain onion and garlic, which are potent sources of fructans. This combination makes them a double threat for anyone sensitive to FODMAPs.
Pro Tip: Always read the label! Even if a product seems simple, hidden high-FODMAP ingredients like onion powder are common.
How to Reduce FODMAPs in Beans: 4 Key Strategies
You can significantly reduce the FODMAP content of beans through proper preparation. Key methods include using rinsed canned beans, soaking and boiling dried beans, sprouting, and strictly controlling portion sizes.
Remember that key fact about water-soluble FODMAPs? This is where we put it into action! Rinsing canned beans isn’t just for cleaning them—it’s actively removing symptom triggers. Because GOS and fructans dissolve in water, we can use specific techniques to wash them away.
Here are the four most effective strategies:
- Choose Canned and Rinse Thoroughly. This is the easiest and most effective method. During the canning process, a significant amount of the oligosaccharides leach out of the beans and into the brine. When you open a can, pour the contents into a colander and rinse them under running water for at least 30 seconds. This simple step washes away a substantial portion of the FODMAPs.
Soak and Boil Dried Beans (The Long Way). If you prefer to use dried beans, you can still reduce their FODMAP load. Soak them in a generous amount of water overnight (or for at least 8-12 hours). Crucially, you must discard the soaking water, as this now contains the leached FODMAPs. Then, boil the beans in fresh water until they are tender and drain them well.
Try Sprouting. Sprouting certain legumes, like mung beans, can also help lower their FODMAP content as the sprouting process breaks down some of the complex carbohydrates.
Master Your Portion Size. This is the most important rule of all. Even with low-FODMAP beans, size matters. Exceeding the Monash University-recommended serving sizes can lead to what’s known as “FODMAP stacking.”
FODMAP Stacking occurs when you eat multiple “safe” servings of different low-FODMAP foods in one meal. While each food is low in FODMAPs on its own, the small amounts can add up, pushing your total intake into the high-FODMAP range and triggering symptoms.
Safe Low FODMAP Bean Choices & Serving Sizes
Choose canned, drained chickpeas (¼ cup), lentils, or black beans (2 tbsp) for low FODMAP options. Precise portion control is non-negotiable.
Now that you know how to prepare beans, let’s look at which beans you can safely incorporate into your diet during the elimination phase. The following table, based on Monash University data, outlines the safest choices and their strict serving sizes for 2025. Always remember to buy canned varieties and rinse them thoroughly.
| Bean Type | Preparation | Low FODMAP Serving Size (oz/g) | Low FODMAP Serving Size (cups/tbsp) | Main FODMAP Type |
|---|---|---|---|---|
| Chickpeas | Canned, Rinsed | 1.48 oz / 42g | ¼ cup | GOS |
| Lentils (Brown/Green) | Canned, Rinsed | 1.62 oz / 46g | ¼ cup | GOS |
| Black Beans | Canned, Rinsed | 1.41 oz / 40g | 2 tablespoons | GOS |
| Butter Beans | Canned, Rinsed | 1.23 oz / 35g | ¼ cup | GOS |
As you can see, the safe serving sizes are quite small. This is why precise measurement and avoiding FODMAP stacking are absolutely critical for success.

Advanced Tip: Using Enzyme Supplements like Beano or FODZYME
Supplements with the enzyme alpha-galactosidase may help you tolerate beans by breaking down GOS. Always consult a dietitian before trying enzyme supplements.
For some individuals, an enzyme supplement can be a helpful tool for reintroducing higher FODMAP foods after the elimination phase. Products like Beano or FODZYME contain the enzyme alpha-galactosidase—the very enzyme our bodies lack. When taken with a meal containing beans, this enzyme gets to work in your gut, helping to break down the GOS before it can cause fermentation and symptoms.
While this sounds like a magic bullet, these supplements are not a license to eat unlimited quantities of high-FODMAP foods, and they don’t work for everyone. Their effectiveness can vary greatly from person to person.
Important: The low FODMAP diet is a complex diagnostic tool. You should only try enzyme supplements or reintroduce high-FODMAP foods under the guidance of a registered dietitian who specializes in digestive health. They can help you determine if these products are right for you and guide you through the process safely.
