Zucchini benefits: fruit or vegetable, uses and cautions

Updated on 21 September 2026Published on 1 May 2018

Zucchini is a young squash, picked before it matures, and it is 95% water. That makes it one of the lightest vegetables in the summer garden and one of the easiest to use — grated raw, grilled, juiced, or laid in cool slices on tired skin. Here is what tradition does with the fruit, the flowers and the peel, and what to watch out for.

What it is credited with

Water balance. Its very high water content has long given it a reputation as a gently diuretic vegetable, and naturopathy includes it in lighter, water-rich eating plans.
Digestive comfort. Traditionally eaten for its fibre, which folk practice credits with keeping transit moving; zucchini juice in the morning is an old household habit for sluggish digestion.
Light eating. Because it is so low in calories and fat, naturopathy treats it as a staple of slimming menus, used to bulk out a plate without weighing it down.
Soothing on the skin. Herbal and household tradition uses cool slices on sun-stressed skin and on puffy eyes, in the same way cucumber is used.
Seeds. Cucurbit seeds have a long folk reputation as a household remedy for intestinal worms, and zucchini seeds are chewed in the same tradition.
Beauty routines. Grated pulp and zucchini juice have a reputation in home cosmetics for softening rough skin, especially on the heels, and for adding shine to hair.

How to use it

In the kitchen

Raw: slice or shave a small, firm zucchini paper-thin, dress with olive oil and lemon, add tomato and mozzarella.
Grated: for a zucchini tzatziki, grate one zucchini, let it sweat on kitchen paper for 15 minutes, then mix with two Greek yoghurts, garlic, a little mustard and olive oil.
Cooked: ratatouille, omelettes, lasagne, quiche, or mashed. Round varieties are made for stuffing.
Skewers: alternate cubes of zucchini, pepper and meat; the cubes hold their shape if left chunky.
Cold soup: zucchini and chive soup, blended and chilled, served in small glasses.
Samosas: grate one zucchini and one carrot, add goat cheese and a teaspoon of mustard.
Flowers: use them the day you pick them — dipped in batter and fried, or torn raw over a salad.
Leaves: the youngest ones, finely shredded, go into mixed salads.
Sweet: grated zucchini disappears into cakes and puddings, much like carrot.

The juice

Wash a young unpeeled zucchini, cut into chunks, pass through a juicer or blend and strain.
Traditionally taken as a small glass in the morning, before breakfast.
Drink it the day you make it — it separates and turns flat within hours.
A squeeze of lemon lifts the rather bland taste.

The seeds

Scoop the seeds from a mature fruit, rinse and dry them on a cloth.
Folk practice is to chew a small spoonful, several times over the day, for a few days at a time.
They can also be crushed to a paste with a little honey, which makes them easier to swallow.

On the skin

Puffy eyes: lay two cool slices of peel, skin-side out, over closed eyelids for 10 minutes.
Sun-stressed skin: place unpeeled slices straight from the fridge on the affected area for a quarter of an hour.
Face: a simple mask of thin raw slices, left on for 10 to 15 minutes, then rinsed.
Rough heels: wrap grated zucchini around the heel, hold with a cloth, leave for 20 minutes.
Hair: before washing, work in zucchini juice mixed with a teaspoon of olive oil and a little milk, then shampoo out.

Cautions

Pregnancy: zucchini is not contraindicated for pregnant women — quite the opposite, it is a standard, well-tolerated part of the diet. Wash it thoroughly, as with all raw vegetables, and mention any seed or juice cure to your midwife or doctor first.
Breastfeeding: zucchini as a food is unproblematic. Concentrated seed preparations are another matter and are better avoided without professional advice.
Bitter fruit — spit it out. A zucchini that tastes bitter contains cucurbitacins, which cause stomach cramps and diarrhoea. Never eat it, and never eat fruit from seed saved off ornamental gourds or squashes.
Children: cooked zucchini is a classic first vegetable. Seed cures and juice regimes are for adults, not for children, unless a health professional says otherwise.
Medication: if you take diuretics, blood pressure medicines or anything affecting potassium or kidney function, ask your doctor before drinking zucchini juice regularly.
Kidney or urinary problems: do not use a water-rich vegetable as a substitute for medical follow-up.
On the skin: test a slice on the inner forearm first. Never apply to broken skin, blistered sunburn or an open wound.
None of this replaces a diagnosis or a prescription. Persistent symptoms belong with a health professional.

Frequently Asked Questions

The one thing to remember: pick them small, leave the skin on, and keep a couple of chilled slices for tired eyes at the end of the day.

Can I eat zucchini raw?

Yes, provided it is young, firm and well washed. Shave it thin or grate it, dress it with olive oil and lemon, and eat it the same day. Raw is also how you keep the vitamin C, which cooking reduces.

Is zucchini safe during pregnancy?

Zucchini is not contraindicated in pregnancy — quite the opposite, it is a common and well-tolerated vegetable. Wash it well, as you would any raw produce. Seed cures and daily juice regimes are a different matter and should be cleared with your midwife or doctor.

My zucchini tastes bitter. What should I do?

Spit it out and throw the whole fruit away. Bitterness signals cucurbitacins, which upset the stomach badly. This happens most often with fruits grown from home-saved seed that has crossed with ornamental gourds.

How do I use zucchini on my skin?

Chill the fruit, cut unpeeled slices and lay them on the area for 10 to 15 minutes — over closed eyelids for puffiness, on sun-stressed skin to cool it. For rough heels, wrap grated pulp around them in a cloth. Always patch-test first, and never apply to broken skin.

Can I eat the flowers and the leaves?

Yes. The flowers are best fried in batter or torn raw over a salad, but they must be used the day they are picked because they collapse within hours. The youngest leaves can be finely shredded into mixed salads.
