Collard Greens
Vegetables · Leafy Greens
Collards are the leaf you can use as a container. A chopped cup, 90 g, is rated green on 0.05 g of fructans and nothing else, and the leaves are sturdy enough that blanched and de-spined they wrap like a soft tortilla. The trouble is never the greens; it is the onion the pot was built on.

Breakdown for 1 cup
Is collard greens low FODMAP?
Fructans do all the work here and they barely trouble the scale: 0.05 g in the measured cup, half the 0.1 g point at which fructans begin to register against a portion. Lactose, excess fructose, GOS and both sugar alcohols read zero. Collards are a cabbage by botany, the same species as kale and broccoli, which is why people brace for them and expect a brassica to misbehave. The number says otherwise. One cup is all that has been measured, so treat larger platefuls as unmapped rather than cleared.
Collard Greens and IBS: what to know
A pot of Southern-style greens is where this goes wrong, and it is worth being exact about why. The leaves simmer for an hour or two with onion, garlic and a smoked ham hock, and the pork is not the problem: onion is rated red at a single chopped tablespoon, 10 g, on 0.4 g of fructans, and a pot of greens takes a whole one. Fructans dissolve in water, so they finish up in the pot liquor, and greens that have sat in that liquid all afternoon have been steeping in it. Lifting the leaves out helps; building the pot without the allium helps far more.
Gut-friendly ways to eat collard greens
Use the leaf as a container. Cut out the spine, dip the leaf in boiling water for half a minute and then straight into cold, and it turns pliable and vivid green without going slack, ready to roll around rice, chicken and grated carrot. A large wheat tortilla, 70 g, is rated amber on 0.24 g of fructans and 0.08 g of GOS, so this is a swap that changes the arithmetic rather than a gesture. For a hot side, shred the leaves finely, hit them with garlic-infused oil, chilli and a splash of apple cider vinegar, and stop well short of an hour.
Frequently asked questions
How much collard greens can I eat in one meal?
One cup of chopped leaves, 90 g, is the tested amount and it is rated green. Measure it raw, because collards shrink hard in the pan and a heaped plate of cooked greens started life as considerably more than a cup. Nothing beyond that portion appears in our data, so a large helping is unmeasured. The seasoning almost always matters more here than the quantity does.
Are Southern-style collard greens low FODMAP?
As they are usually made, no, and the greens are innocent. Onion and garlic go in at the start of the braise, where nothing can be picked back out, and the liquid they leave behind is served with the leaves or absorbed by them. You can keep the smoke and lose the trigger: smoked paprika, a piece of bacon, black pepper and vinegar give you most of that flavour without an allium in the pot.
Can you eat collard greens raw?
You can, though a whole raw leaf is chewy work. Shredded into ribbons as thin as you can cut them, rubbed with oil, salt and lemon and left for ten minutes, collards soften into a salad that holds a dressing for a day without wilting. The tested cup covers the leaf either way, since cooking changes texture and volume rather than the fructan figure behind the rating.
Are collard greens the same as kale?
Same species, different habit. Kale grows in curled or crinkled leaves on a stem and collards grow broad and flat, which is exactly why one makes chips and the other makes a wrap. Both are rated green at the cup of chopped leaves that has been measured for each, though the cups are not the same weight, so quantities are not interchangeable if you are counting closely.
