Black Beans (canned, drained)
Legumes & Tofu · Legumes
A quarter cup of drained canned black beans, 40 g, is rated green, and the next step up, half a cup at 80 g, is rated red. The useful thing is that a cleared portion exists at all: canned cannellini and canned kidney beans are already amber at their smallest tested serves. Black beans are the ones to build a bowl around.

Breakdown for 0.25 cups
Is black beans (canned, drained) low FODMAP?
GOS decides it, and the two tested points sit either side of the line. A quarter cup holds 0.15 g of GOS with 0.08 g of fructans; the bigger scoop doubles both, and 0.3 g of GOS is the level counted as high, so the rating flips. Those figures assume the tin has been drained and rinsed, which is the only reason a bean has a green step at all. The mechanism behind that is set out in full on the canned chickpeas page.
Black Beans (canned, drained) and IBS: what to know
Black beans belong to dishes that are served by the ladle. A burrito bowl, a pot of chilli, a bean salad at a barbecue: each is designed so the bean does the filling, and two scoops carries you from the cleared portion to the red one with no step between. Chipotle black beans are rated red for that reason, since a counter scoop is not a quarter cup. When you cook, decide how many servings the tin makes before you open it, then put the rest in the fridge.
Gut-friendly ways to eat black beans (canned, drained)
Stretch one scoop across a plate that is mostly something else. White rice and corn tortillas give a bowl its bulk, so the beans read as an ingredient instead of the base, and cumin, smoked paprika and lime handle the flavour that onion and garlic would otherwise carry. When you want more plant protein in the same meal, tempeh is rated green at a serve you can genuinely eat as dinner, and it browns in the same pan.
Frequently asked questions
How many black beans can I eat on a low FODMAP diet?
A quarter cup of the drained tin is the cleared serve and half a cup is the red one, with nothing tested in between. On a plate that is roughly two heaped tablespoons through a salad or over rice, once in a day rather than at every meal. Weigh it out once so you know what it looks like in your own bowl.
Are black beans in a burrito bowl low FODMAP?
Not at a counter scoop. Chipotle black beans are rated red as served, and most build-your-own bowls use a ladle of similar size. Ask for beans on the side and take a spoonful, or skip them and load up on rice and meat. At home the same bowl works with a measured quarter cup and a low FODMAP salsa.
Do canned black beans need to be rinsed?
Rinse them, because the green figure depends on it. Tip the tin into a sieve and run cold water over the beans until the water comes off clear, which takes longer than most people give it. Never keep the black liquid as a sauce base, however good the colour looks, because that liquid is precisely what you were trying to leave behind.
Are black beans better than kidney beans for IBS?
They start from a better place. Black beans have a cleared tested portion, while canned kidney beans are rated amber at three tablespoons and canned cannellini are amber from a quarter cup. If a recipe calls for a mixed bean tin, using black beans alone gives you a portion you can count. All three still respond to the same lever: drain, rinse, serve less.
