Kohlrabi in Ayurveda: Benefits, Dosha and How to Eat It

Kohlrabi (Brassica oleracea var. gongylodes) is a cruciferous vegetable, like cauliflower and rutabaga already covered on this site, grown for the swollen bulb that forms at the base of its stem. Its crunchy texture and mild, faintly peppery raw flavor make it a versatile vegetable: grated raw into a salad, or simmered until soft and melting once cooked. Still uncommon on most Western tables, it deserves a more regular place, especially within an Ayurvedic approach that favors root and stem vegetables in winter, alongside Jerusalem artichoke.

This article covers its profile through the Ayurvedic lens of the six tastes, its place across the doshas, and the best way to prepare it for easy digestion.

A sweet taste with a peppery edge

Through the lens of the six tastes, kohlrabi has a dominant sweet (madhura) profile, with a more pronounced peppery note when raw that softens noticeably once cooked. Its light and mildly drying nature traditionally makes it an interesting vegetable for Kapha, the dosha most prone to heaviness, which benefits from its lightness and crunch. Its fibrous texture, on the other hand, calls for cooking and pairing with a healthy fat for Vata, already dry by nature; Pitta tolerates it well in moderate amounts, especially cooked rather than raw.

Dosha	Effect of kohlrabi
Vata	Best eaten cooked, with a healthy fat (ghee, oil) to offset its fibrous texture
Pitta	Neutral to favorable in moderate amounts, preferably cooked
Kapha	Favorable: its lightness and crunch counterbalance the tendency toward heaviness

What does research say about kohlrabi?

A study by Yang, Cha and Lee, published in 2015 in the Korean Journal of Community Living Science (vol. 26, no. 2, p. 405-414), compared the flesh and peel of a purple kohlrabi, finding antioxidant activity and an antiproliferative effect on several human cancer cell lines cultured in the lab, with flavonoid and anthocyanin concentrations markedly higher in the peel than in the flesh (see the study on Google Scholar). This study was carried out in the lab on concentrated extracts, not on everyday human consumption of the vegetable: it documents an interesting antioxidant potential, particularly in the peel of purple varieties, without proving a health benefit for people who eat kohlrabi regularly.

Raw or cooked: how to prepare it?

• Raw, grated or thinly sliced: ideal for Kapha in a salad, crunchy and slightly peppery, best limited for Vata because of its fibrous texture when raw;
• Cooked, in a soup or simmered: its texture turns soft and its flavor mellows noticeably, a more digestible form that suits both Vata and Pitta better;
• The leaves, often thrown away, can be cooked like spinach or greens and deserve to be kept rather than wasted;
• Pair it with carminative spices such as cumin or ginger, which support agni against this cruciferous vegetable.

Our spiced kohlrabi soup recipe details a cooked preparation, gentler and easier to digest than the raw vegetable.

Is kohlrabi easy to digest?

Raw and in large amounts, kohlrabi can cause bloating in people with sensitive digestion, as is often the case with raw cruciferous vegetables. Cooked, it becomes noticeably easier to digest. Proper cooking and a reasonable portion remain the key to its digestive tolerance, a point covered in more detail in our bloating and digestion article.

How to choose and store kohlrabi?

A good kohlrabi feels firm to the touch, with no cracks or soft spots, and is preferably medium-sized: very large bulbs tend to be more fibrous and less tender at the center. Varieties come in pale green and purple, the latter being, according to the study cited above, richer in antioxidant compounds in the peel. It keeps for one to two weeks in the refrigerator, with the leaves removed if stored separately for cooking.

Precautions

Like other cruciferous vegetables, kohlrabi contains goitrogenic compounds that, in very large and prolonged amounts, may interfere with thyroid function in people who already have a fragile thyroid; normal cooking and reasonable consumption within a varied diet pose no problem for the vast majority of people. If you have a medically monitored thyroid condition, ask your doctor about the place of cruciferous vegetables in your diet. This vegetable is part of a balanced diet and never replaces medical advice. Find our full recommendations in our safety and precautions guide.
