Is tea (fennel, strong brew) low FODMAP?

This is a strong infusion made with one teabag steeped for three to five minutes. All six groups are low in the small green portion. At the full-cup reference, GOS joins fructans as an elevated group, so describing the drink simply as 'herbal' misses an important portion distinction. These are liquid amounts for the tea, not serving weights for fennel bulb or leaves.

Tea (Fennel, Strong Brew) and IBS: what to know

If fennel tea forms part of your routine, record the actual amount and the strength rather than assuming a digestive-themed product is suitable for any serving size. A green FODMAP rating describes the measured portion; it does not establish an IBS treatment effect. Added honey, milk or other herbs should be considered separately.

Gut-friendly ways to eat tea (fennel, strong brew)

Use a measuring jug because the green amount is small enough to be difficult to estimate in a mug. Prepare the stated infusion first and measure the quantity you drink. For a comparison with another strong herbal tea, use the individual guides for dandelion and chamomile. Do not substitute a fennel-seed cooking portion for the brewed tea volume.
