Courgette guide: Calories, nutrition & benefits

23 Nov 2022 • 5 min read

Courgettes are a delicious and versatile veggie that can work well in so many recipes, but did you know this summer squash also boasts many impressive health benefits?

Whether you love yours in stews or soups, roasted, grilled or pickled, there are plenty of health benefits to eating delicious courgettes. Here we look at just a few of them…

What is a courgette?

Believe it or not, courgettes aren’t a vegetable, but a fruit because they are full of seeds. This cucumber-looking and shaped veg is part of the Cucurbit family, which also happens to be home to squash and cucumbers.1

It’s possible to get courgettes in all different shapes and sizes, including curly courgettes, which are called Tromboncino or Tromba courgettes.

In the UK, courgette season is from June to October. When choosing courgettes, select ones that are small and firm with unblemished skin. They should also feel quite heavy for their size too.

What’s the difference between a courgette and a zucchini?

Courgette? Zucchini? Are they the same thing? Or are they two completely different things? Courgettes and zucchinis are in fact the same thing, it’s just that in some countries, they go by a different name.2

Zucchini comes from the Italian word ‘zucchino,’ which means ‘tiny squash’ or ‘undeveloped marrow.’

Meanwhile, courgette means the same thing, but in French. Zucchini is the common term used in American English speaking countries, while courgette is the more common term among French and British English speaking people.

Can courgettes be eaten raw?

Yes, absolutely. It’s not uncommon for young courgettes to be eaten raw. They can be shaved into ribbons or finely sliced into salads.3

Other recipe ideas include dressing them with chilli, chopped mint, lemon and extra virgin olive oil.

They can also be sautéd, roasted, grilled or barbecued. Meanwhile, given their size, larger courgettes can be stuffed. Courgette flowers are also edible and can be filled with ingredients, such as ricotta and mint.

Are courgettes fattening?

Courgettes contain minimal calories and lots of water, making them far from fattening. While they aren’t packed full of nutrients, they do contain plenty of Vitamin C, which is good for supporting the immune system, and potassium, which can help maintain normal blood pressure.4

Carbs 3g
Sugar 1g
Fibre 1g


As you’ll see from the nutritional overview above, there are a lot of plus points to eating courgettes.

They are low in calories and contain no saturated fats or cholesterol. They’re also an excellent source of dietary fibre, carbs and protein. They happen to be full of water too (more on this below).

9 benefits of courgettes

  1. High in antioxidants

We’re all trying to eat more antioxidant-rich foods, and courgette is a great way to boost your intake. Courgettes contain plenty of carotenoids, such as lutein and beta-carotene, which can boost your eye, skin and heart health.6

  1. Fibre

There’s plenty of soluble and insoluble fibre in courgettes, which is excellent news for gut health and digestion.

Soluble fibre can feed the healthy bacteria in your gut, which can, in turn, help reduce the incidence of gut disorders such as Irritable Bowel Syndrome and Crohn’s.7

Meanwhile, insoluble fibre helps add bulk to stools and makes digesting and passing food more straightforward.8

  1. Vitamin C

With lots of immune system-supporting Vitamin C, particularly in the skin, eating courgettes may help to protect cells and keep them healthy.

Vitamin C is also essential for maintaining healthy skin and bones. Because our bodies can’t store Vitamin C9, you need to make sure you’re getting enough in your daily diet.

Hitting your Vitamin C levels shouldn’t be too tricky, but incorporating a few tasty courgettes into your weekly routine is a great way to boost your intake.

  1. Potassium

Courgettes also contain significant levels of potassium.10 Most of this is in the dark green skin of the vegetable, so be sure to use the whole thing in your recipes.

Potassium is good for controlling blood pressure and can also help maintain healthy water levels, digestion and heart health.11

Your body can’t produce potassium naturally, so you must make sure there’s plenty in your diet; courgettes are a fantastic source!

  1. Water content

One of the biggest benefits associated with courgettes is their high water content.

They happen to be made up of around 95% water. That’s 3% more than watermelons and 1% less than lettuces.12

Water is essential for overall good health. It’s key for muscle flexion, transporting oxygen to the cells, and a host of other biological functions.

Courgettes are an excellent way to rehydrate, as well as take on natural sugars and electrolytes, such as potassium, that are lost during workouts.

  1. Blood sugar levels

Courgettes may potentially help lower blood sugar levels in people with Type 2 diabetes due to the fact they’re so low in carbs.

The fibre that’s found in courgettes can also reportedly help stabilise blood sugar levels and prevent spikes. It can potentially increase insulin sensitivity too, which can help even out blood sugar.13

  1. Heart health

The fibre that’s present in courgettes can reportedly help reduce the risk of heart disease. Courgettes contain the soluble fibre, pectin, which has been found to be effective at reducing bad cholesterol levels.14

A review of 67 studies found that consuming around 2 to 10g of soluble fibre a day for around 1 to 2 weeks can reduce, on average, total cholesterol by 1.7mg/dl and ‘bad’ cholesterol by 2.2mg/dl.

What’s more, the potassium content may help to lower blood pressure due to its ability to dilate blood vessels.

  1. Eye conditions

Courgettes contain Vitamin C and beta-carotene, which are recognised as being two important nutrients for eye health.15

On top of this, courgettes also contain two antioxidants, lutein and zeaxanthin. Research has found that these two antioxidants can help improve vision and reduce the risk of developing age-related eye diseases, such as macular degeneration.

What’s more, high levels of lutein and zeaxanthin may also reduce the likelihood of developing cataracts, which can lead to poor eyesight.

  1. Weight loss

It’s believed that regularly eating courgettes may potentially help people lose weight. This is due to the fact they’re full of water and have a low calorie density, two things that can help us feel fuller for longer.

The fibre content can also potentially keep hunger at bay too.16

Why courgettes are bad for you

On the whole, there’s a lot to love about courgettes. They contain minimal calories, are full of water and are extremely versatile.

There aren’t many risks associated with eating courgettes however, there are reports of the impact it may have on the body due to the fact it contains oxalates.

They’re naturally produced in the body, but large amounts of them can crystallise and turn into kidney stones. As a result, eating lots of courgettes in one go isn’t recommended.17

Meanwhile, courgettes can also be covered in pesticides, so it’s best you thoroughly wash them before eating them raw or cooking with them.


  • Courgettes are low in calories and contain no saturated fats or cholesterol
  • They are associated with lots of health benefits due to the fact they are high in antioxidants and contain fibre, potassium, Vitamin C and lots of water, among other nutrients

How to prepare and use courgettes

Courgettes are relatively easy to prepare.

Simply wash them before cooking and give the skin a light scrub where the prickles may have been.

Then cut off the top and the bottom; you don’t have to peel the skin, this can, and should, be kept on because that’s where a lot of the nutritional goodness (Vitamin C, potassium and fibre) is found.18

In terms of how you use courgettes, you can:

  1. Eat them raw in salads.
  2. Fry, bake, steam, boil or stuff them.
  3. Mix them with potatoes, carrots, asparagus or green beans in curries and stews.
  4. Chop, grate or shred them into bread or on to pizzas.
  5. Add smaller, finger-sized courgettes to stir fries.
