Jerusalem artichoke calories come to 110 for 1 cup sliced (150 g) and 73 per 100 g, raw. The thing to notice is where they come from: 90% of the calories are carbs, and 9.6 g of every 100 g is sugar. Fat is 0 and protein is just 2 g, so portion size and cooking fat decide the total.

A sliced cup is a 110-calorie side
A cup of sliced raw Jerusalem artichoke weighs 150 g and lands at 110 calories, about 5% of the daily value for energy. A 3 oz portion (85 g) drops to 62 calories, roughly what you get from a handful of thin slices tossed into a salad. At either size, this tuber barely dents a day of eating.
The total climbs fast once it becomes the main event. Two cups (300 g) come to 219 calories, three cups (450 g) to 329, and a big roasting tray of five cups (750 g) to 548. That last figure is a meal-sized number, so if you roast a whole bag and graze from the pan, weigh it first.
Protein rises from 6 g to 15 g across those same multiples, which is modest for the calories involved. Sodium stays tiny the whole way, topping out at 30 mg for five cups. Log by weight when you can, because a cup of uneven, knobby slices can drift well above or below 150 g.
Carbs supply 90% of the calories
Per 100 g, Jerusalem artichoke carries 17.4 g of carbohydrate, 2 g of protein and 0 g of fat. That makes the calorie split 90% carbs, 10% protein and 0% fat. In practice it behaves like a starchy vegetable, not a leafy one, and it belongs in the same mental slot as potatoes on your plate.
A cup brings 26.2 g of carbs and 3 g of protein, which is 6% of the 50 g daily value for protein. That protein share is small, so the tuber will not do the job of a protein food. It fills space and adds texture; it does not carry a meal on its own.
With no fat at all, every calorie you add with butter or oil is extra on top of the raw figures. If you track carbs, the 3 oz portion and its 14.8 g is the easiest amount to fit into a lower-carb day without giving the vegetable up entirely.
Sugar is the row to watch, not sodium
Of the 17.4 g of carbs per 100 g, 9.6 g are listed as sugars. In a sliced cup that becomes 14.4 g of sugars inside 26.2 g of total carbs, a larger sugar share than most people expect from a knobby root. If you are watching sugar, count this tuber the way you would count a piece of fruit.
Fiber is listed at 1.6 g per 100 g and 2.4 g per cup, measured against a 28 g daily value. That is a modest contribution. Do not count on Jerusalem artichoke alone to cover your fiber; pair it with beans, greens or whole grains if that row matters to you.
Sodium barely registers: 4 mg per 100 g and 6 mg per cup, 0% of the 2300 mg daily value. Potassium is the standout mineral at 429 mg per 100 g, set against a 4700 mg daily value. Cholesterol and saturated fat are both 0, so the only rows that move are carbs and sugars.
Pair it with protein and a little fat
With 2 g of protein and no fat per 100 g, Jerusalem artichoke is a side, not a meal. Put it next to chicken, fish, eggs, tofu or beans and the plate starts to look balanced. The protein food brings the staying power that the tuber lacks.
The usual ways to cook it, roasted in oil or mashed with butter, add calories the raw figures do not show. If you are counting, log the oil or butter as its own item rather than guessing it into the vegetable. Raw slices shaved thin into a salad keep the total closest to the numbers on this page, and they add a crisp, nutty bite.
A sensible default is one sliced cup next to a lean protein and a pile of leafy greens. That keeps the side at 110 calories and leaves room for a modest drizzle of oil. Snap a photo of the plate and BodyPal can log the Jerusalem artichoke for you; then check the weight against the 150 g cup if your slices look generous.
How does jerusalem artichoke compare?
Here is how Jerusalem artichoke stacks up against artichoke, purple potato and carrot stick, per 100 g and per usual serving.
Verdict: For the fewest calories pick carrot stick at 41 per 100 g or artichoke at 53, both well under Jerusalem artichoke's 73. If you want a starchy side that still undercuts potato, Jerusalem artichoke beats purple potato's 93 per 100 g.
