🥬 Tomatoes

Low FODMAP

Tomatoes are a versatile fruit (botanically speaking) that plays a starring role in cuisines worldwide. For those following a Low FODMAP diet, tomatoes offer good news: they're generally well-tolerated and can add vibrant flavor, color, and nutrition to your meals without triggering digestive symptoms. Fresh tomatoes contain minimal FODMAPs, making them a safe choice for most people with IBS. The key consideration is portion size and ripeness. Ripe, red tomatoes are lower in FODMAPs than unripe green tomatoes, which contain higher levels of fructans. Common varieties like cherry tomatoes, grape tomatoes, roma tomatoes, and beefsteak tomatoes are all suitable options when consumed in appropriate portions. Canned tomato products require more attention. Plain canned whole tomatoes, diced tomatoes, and crushed tomatoes are typically Low FODMAP in moderate servings, but always check labels for added high FODMAP ingredients like onion or garlic. Tomato paste and sun-dried tomatoes are more concentrated and should be limited, as the FODMAP content increases with concentration. Nutritionally, tomatoes are powerhouses for gut health and overall wellness. They're rich in lycopene, a potent antioxidant that gives tomatoes their red color and has been linked to reduced inflammation. They also provide vitamin C, potassium, folate, and vitamin K. The fiber content in tomatoes is gentle and well-tolerated by most people, supporting healthy digestion without overloading the gut. When cooking with tomatoes, remember that cooking doesn't significantly change their FODMAP content, so both raw and cooked tomatoes are suitable. Fresh tomatoes work beautifully in salads, salsas, and as toppings, while canned varieties are perfect for sauces, soups, and stews. Remove seeds if you find them irritating to your digestive system, though this isn't FODMAP-related. For maximum flavor and nutrition, choose tomatoes that are fully ripe and store them at room temperature until cut. Refrigeration can diminish their flavor and texture. Whether you're making a simple caprese salad, a hearty pasta sauce, or roasting them for a side dish, tomatoes remain one of the most reliable and delicious Low FODMAP ingredients in your kitchen arsenal.

Safe Portion

1 medium tomato (150g) or 1 cup cherry tomatoes (149g) per serving; ½ cup canned diced tomatoes (123g)

🔬 Science Note

According to Monash University FODMAP research, common tomato (ripe) is Low FODMAP in servings up to 1 medium tomato (150g). Cherry tomatoes are Low FODMAP up to 1 cup (149g). Canned diced tomatoes are Low FODMAP at ½ cup (123g) but become moderate for fructans at 1 cup. Tomato paste is moderate to high FODMAP due to concentration, with only 2 tablespoons (43g) considered Low FODMAP. Sun-dried tomatoes should be limited to 4 pieces (8g) to remain Low FODMAP. Unripe (green) tomatoes contain higher fructans and should be avoided or strictly limited. The ripening process reduces FODMAP content, making fully ripe red tomatoes the best choice for sensitive individuals.
