Ever heard of a sunchoke? You’re not alone if you haven’t: it’s not a common vegetable for many of us, but it’s a vegetable that is worth finding it’s way into our diet.
Also known as a Jerusalem artichoke, sunchokes are the tuberous root of the sunchoke plant, a relative of sunflowers. Sunchokes are knobby and misshapen, with a papery skin and flesh the texture of a radish when eaten raw, and creamy like a potato when cooked.
So why bother learning about this funny little tuber and consider adding it into your diet? Gut health. Our digestive systems need all the help they can get from foods that contribute to a finely operating gut, especially if we have trouble with blood sugar imbalance, have received antibiotic treatment, or suffer from digestive distress including stomach upset or IBS, Crohn's or colitis. Jerusalem artichokes - like other inulin-rich sources such as chicory root (most often consumed as an herbal tea or coffee substitute), asparagus, artichokes, dandelion root, onions and garlic - can help.
Inulin is a carbohydrate that acts as a soluble dietary fiber: whole foods inulin sources are considered natural prebiotics, which help establish a healthy intestinal environment by stimulating the growth of beneficial intestinal bacteria. A healthy intestinal environment prepares us to access the benefits of probiotic foods such as unsweetened yogurt and kefir, unpasteurized sauerkraut, kimchee, miso and other fermented foods that contain beneficial bacteria.
So if you’re willing to give a sunchoke a try, there are very simple ways to get them into your diet. Buy a small amount, scrub them well with a vegetable brush, and slice them thinly to eat them raw with a healthy dip like hummus or white bean dip, or substitute them where canned water chestnuts are typically called for. To cook, clean them the same way, then slice them into 1/4” crosswise pieces, cover with salted water and gently boil until tender. Then mash with a little olive oil, salt and pepper and eat as a vegetable side with your dinner. (You could also go half and half with potatoes on that one). To roast, prep them as above, then toss with coconut oil, salt and pepper and roast for 30 minutes - alone or as part of a big pan of roasted vegetables - until tender and caramelized.
Or try this simple soup, put together in 10 minutes with a few other basic ingredients and simmered for less than an hour.
