Vegetable cocktails made with mineral water or milk are prepared from leek, romaine lettuce or parsley, apples, and carrots. The main difference between base options is that a milk-based vegetable smoothie feels filling, while a diet version made with carrot and greens and mineral water feels light. The unusual ingredient in this carrot-and-apple detox drink shouldn’t put anyone off: leek adds a gentle, barely-there peppery note that balances nicely with sweet apple. Leek’s benefits in the smoothie come from its potassium, magnesium, phosphorus, vitamin C, and riboflavin, which help regulate metabolism. Beyond those nutrients, this cleansing drink is low in calories, so a leek-based vegetable smoothie is a smart choice for weight loss.

Frequently asked questions about leek smoothies

How should you pair fruits and vegetables in a smoothie?
Pair fruits and vegetables in a smoothie by balancing taste, nutrition, and texture. The main principle is to use sweet fruits to mask the taste of vegetables and to keep the right proportions. The best ratio is about 60% fruits or berries to 40% vegetables and greens. This proportion creates a tasty drink that won’t taste bitter. Banana, apple, mango, pear, and pineapple work well to overpower greens and create a creamy texture. From vegetables and greens, spinach (neutral flavor), cucumber (adds freshness and liquid base), celery, broccoli, carrot, and beet pair best.

An evening leek detox smoothie will support digestion and help reduce swelling by morning.
How many calories are in a leek and apple smoothie?
The calorie count of a vitamin drink with carrot and apple depends on the liquid base. A smoothie made with mineral water contains roughly 80–100 kcal per 300–350 ml serving, since the ingredients are low-calorie vegetables and one or two apples.

Which part of the leek should you use in a smoothie — white or green?
You can use both parts of the stalk in a vitamin cocktail with leek. The white part has a milder, slightly sweet taste, while the green part has a stronger herbal aroma. For a soft, balanced leek-and-apple smoothie, use mostly the white part with a small addition of the green. If you prefer a more intense green drink, add more of the green part—it pairs well with parsley and carrot and enhances the drink’s detox effect.
Do you need to cook or blanch leek before adding it to a smoothie?
No, use leek raw for a vegetable smoothie—heat destroys much of the vitamins and phytoncides that make this ingredient valuable for a detox drink. Simply rinse the stalk thoroughly under running water, cut off the root end, and chop the leek before putting it in the blender. In its fresh form, leek in a smoothie preserves the full set of beneficial nutrients—potassium, , vitamin C, and riboflavin—that help normalize metabolism and support cardiovascular function.
