With barely 32 kcal per 100 g, leek is universally classed as a low-calorie vegetable. Because of this modest calorie count, it is prized in weight-loss menus where controlling calorie intake is essential. Beyond its light calorie contribution, leek supplies a good dose of vitamin K, folate, vitamin C, and the mineral manganese, all of which support normal blood coagulation and immune function. It is also a source of soluble fibre (inulin) that may foster healthy gut flora while keeping calories in check.
Leek contains the flavonoid kaempferol, studied for its supposed antioxidant properties that could help limit oxidative stress, although this benefit is still considered "supposed" by nutrition scientists. Traditionally known as the "asparagus of the poor," the vegetable was already cultivated by the Egyptians and valued by the Romans; Emperor Nero is said to have eaten it daily, convinced it would keep his voice strong—proof that low-calorie foods can still make history.
Because it is largely water (over 90%), leek has a mild diuretic effect, useful for people looking to reduce bloating without adding extra calories. Finally, its subtle onion-like aroma offers depth of flavour without the calorie overload of richer seasonings, making it a strategic ingredient for anyone monitoring their daily calorie budget.
Tips for incorporating leek into a balanced diet
To take advantage of leek's low-calorie profile, prepare a classic leek-and-potato soup by simmering the two vegetables in vegetable stock and blending until silky; swap cream for a splash of semi-skimmed milk to keep calories low. For a protein-rich yet reasonable-calorie lunch, sauté sliced leek with strips of chicken breast and a handful of broccoli florets, finishing with soy sauce. Fans of seafood can roll leek julienne into whole-wheat crêpes and top with flakes of smoked salmon; the smoky aroma compensates for the absence of high-calorie sauces.
Leek also shines in oven dishes: try a crustless quiche combining beaten egg, diced leek, and a sprinkle of Emmental; baking without pastry trims hundreds of calories while still offering comfort food appeal. Remember that portion size still matters: even though leek is low in calories, the béchamel or cheese you add can raise the total calorie count sharply. Pair any leek dish with a raw side such as sliced carrot or cucumber salad to boost volume, fibre, and satiety without driving up calories.
