Is Eggplant a Low FODMAP Vegetable? A Comprehensive Guide

4 min read

According to Monash University, the global leader in FODMAP research, a 1-cup (75g) serving of eggplant is considered low FODMAP. This guide explores how to incorporate this versatile vegetable into a low FODMAP diet without triggering digestive issues.

Quick Summary

Eggplant is a low FODMAP vegetable in specific serving sizes, making it suitable for many with IBS. However, larger portions contain higher levels of sorbitol, a type of polyol, and can increase FODMAP content. Portion control and preparation methods are key to enjoying it safely.

Key Points

  • Portion Control is Key: A serving of 1 cup (75g) of eggplant is low FODMAP, but larger portions become high FODMAP due to sorbitol.

  • Cooking Shrinks Eggplant: Eggplant shrinks when cooked, so measure your portion before cooking to avoid accidentally consuming a high FODMAP amount.

  • Sorbitol is the Culprit: Larger quantities of eggplant contain higher levels of the polyol sorbitol, which can trigger digestive symptoms.

  • Prepare with Care: Cooked eggplant is generally easier to digest than raw. Peeling the skin can also help with digestion for some.

  • Avoid High FODMAP Accompaniments: When cooking with eggplant, use low FODMAP substitutes like garlic-infused oil instead of fresh garlic or onion.

Understanding FODMAPs and Your Digestive System

FODMAPs are a group of short-chain carbohydrates that can be poorly absorbed in the small intestine. For individuals with Irritable Bowel Syndrome (IBS) or other digestive sensitivities, these carbohydrates can ferment in the gut, causing symptoms like bloating, gas, and abdominal pain. A low FODMAP diet is often recommended to help manage these symptoms. The diet works by temporarily restricting foods high in FODMAPs, and then reintroducing them systematically to identify individual triggers.

The FODMAP Content of Eggplant

Eggplant, also known as aubergine, is generally considered a safe choice for those following a low FODMAP diet, but with one important caveat: portion size matters.

  • Low FODMAP Serving: Monash University, a leading authority on the low FODMAP diet, has tested eggplant and determined that a serving of 1 cup (approximately 75g or 2.65 ounces) is low FODMAP.
  • Moderate FODMAP Serving: When you increase the portion to about 2.5 cups (182g), the eggplant becomes moderate in FODMAPs, specifically due to the polyol called sorbitol.
  • High FODMAP Serving: At 3.5 cups (260g), the FODMAP content is considered high.

It is this dose-dependent nature that requires mindful consumption. Because eggplant shrinks significantly when cooked, it is very easy to exceed the low FODMAP serving size unintentionally, especially in recipes that call for large quantities, such as moussaka or parmigiana.

Low FODMAP vs. High FODMAP Vegetables: A Comparison

To better understand where eggplant fits in, here is a comparison of some common vegetables based on their FODMAP content, using information from reputable sources like Monash University.

Vegetable FODMAP Status (in standard portion) Key FODMAP(s) Notes
Eggplant Low (75g/1 cup) Sorbitol (in larger amounts) Safe in controlled portions; cooks down significantly.
Bell Peppers (Green) Low None in low serving A versatile, safe option for adding bulk.
Onions High Fructans A major trigger food; use garlic-infused oil for flavor instead.
Garlic High Fructans Another high-FODMAP staple; garlic-infused oil is a great alternative.
Cauliflower High Mannitol Best to avoid or limit significantly during the elimination phase.
Broccoli Variable (Depends on part) Fructans Florets are lower in FODMAPs than stems; portion control is important.
Kale Low None A safe leafy green to enjoy freely.

Practical Tips for Enjoying Low FODMAP Eggplant

For those on a low FODMAP diet, enjoying eggplant can be simple and delicious with a few adjustments. The key is controlling your portion size and being mindful of other high-FODMAP ingredients.

Preparing Low FODMAP Eggplant

  1. Roasting: Chop eggplant into 1-inch cubes and toss with a low FODMAP oil like garlic-infused olive oil. Roast until tender and golden. This method uses minimal oil and creates a delicious, melt-in-your-mouth texture.
  2. Sautéing: Sauté eggplant cubes in a pan with a small amount of garlic-infused oil until soft. Pair with other low FODMAP vegetables like bell peppers or zucchini.
  3. Grilling: Slice eggplant into rounds, brush lightly with oil, and grill until cooked through. This is a great way to add a smoky flavor without extra oil.
  4. Peeling: For some, the skin of eggplant can be difficult to digest due to its fiber content. Peeling the eggplant before cooking may help improve tolerance for sensitive individuals.

Low FODMAP Eggplant Recipe Ideas

  • Eggplant Wedges: Roast wedges of eggplant coated in gluten-free, low FODMAP breadcrumbs and Parmesan cheese until golden brown. Serve as a side dish.
  • Eggplant Dip (Baba Ganoush Alternative): Make a low FODMAP version of this classic dip by roasting eggplant until very soft, then blending the flesh with tahini, lemon juice, and garlic-infused oil. Avoid recipes that use fresh garlic or onion.
  • Stuffed Eggplant: Create a delicious meal by stuffing hollowed-out eggplant halves with a mixture of low FODMAP ingredients like rice, grated carrot, and chives. Be sure to measure the eggplant amount per serving to stay within the low FODMAP threshold.

The Importance of 'FODMAP Stacking'

Even when eating low FODMAP foods, it is important to be aware of 'FODMAP stacking.' This occurs when you eat several different low FODMAP foods, but the total amount of a specific FODMAP (e.g., sorbitol) accumulates to a level high enough to trigger symptoms. For example, if you eat a low FODMAP portion of eggplant (which contains sorbitol) and also have an avocado (which contains sorbitol) in the same meal, you might exceed your personal tolerance for sorbitol. Keeping track of ingredients and portion sizes is crucial for success.

Conclusion

In summary, is eggplant a low FODMAP vegetable? Yes, but with proper portion control. For most individuals on a low FODMAP diet, a serving of 1 cup (75g) is well-tolerated. The key is to be mindful of how much you consume and the other ingredients in your meal. By using proper cooking methods and managing portion sizes, eggplant can be a nutritious and delicious addition to your diet, helping to add variety and flavor without compromising digestive comfort.

Remember to always consult with a registered dietitian or healthcare professional experienced in the low FODMAP diet for personalized guidance, especially during the elimination and reintroduction phases of the diet.

Frequently Asked Questions

According to Monash University, a low FODMAP serving of eggplant is 1 cup, or approximately 75 grams.

Larger portions of eggplant contain increased amounts of sorbitol, a type of polyol that can cause digestive issues in sensitive individuals.

No, both garlic and onions are high in fructans. Instead, use garlic-infused oil to add flavor without the FODMAP content.

Cooking eggplant breaks down some of its compounds, potentially making it easier to digest for sensitive stomachs. Some find raw eggplant less tolerable.

FODMAP stacking is when multiple low FODMAP foods with the same FODMAP (like sorbitol in eggplant and avocado) are combined, and the cumulative total exceeds your tolerance. It is important to be mindful of all ingredients in a meal.

Traditional eggplant parmesan recipes are usually not low FODMAP due to large quantities of eggplant, high FODMAP breadcrumbs, and onion/garlic. Low FODMAP versions can be made by controlling portions and using modified, safe ingredients.

You can safely combine eggplant with other low FODMAP vegetables such as bell peppers, carrots, bok choy, green beans, and spinach.
