Eating zucchini raw is actually very healthy. But is it true that raw zucchini can be poisonous? Here you can find out everything you need to know.

Eating zucchini raw: these are the advantages

Basically, there is nothing wrong with eating zucchini raw, quite the opposite: zucchini eaten raw is considered to be particularly healthy. It contains iron, a lot of vitamin C and vitamin A – if it is heated, many nutrients and vitamins are lost.

Zucchini should also not be peeled, as the peel contains most of the vitamins. If you wash the shell thoroughly, you can eat it without hesitation.

Due to their high water content, zucchinis are also filling and have comparatively few calories. But what about the rumor that you can’t eat zucchini raw?

When not to eat zucchini raw?

The problem with zucchinis are bitter substances called cucurbitacins:

Like other cucurbits, zucchini naturally contains cucurbitacins. In large quantities, these bitter substances can lead to digestive problems or even food poisoning.
Commercially available zucchini are special breeds that do not contain cucurbitacins. You can eat these without hesitation.
Be careful with homegrown zucchini. In your own garden, under certain circumstances, backcrosses can form, which again contain cucurbitacins.
Cucurbitacins are heat resistant and poorly soluble in water. Therefore, they are also preserved during cooking.
You can recognize an inedible zucchini by its strongly bitter taste.
Store-bought zucchini can always be eaten raw. If you grow your own zucchini, do a taste test first. Bitter-tasting zucchini contain poisonous cucurbitacins and should not be eaten raw or cooked.

Not just with raw zucchini: be careful with these fruits too

Legumes like beans and chickpeas contain phasin. This is a protein that is absorbed into the blood via the intestines and, in high doses, can cause the red blood cells to stick together. It can also cause indigestion and vomiting. Boil chickpeas for at least 15 minutes, then the phasin will become harmless.
Raw potatoes that have sprouted or green spots may contain solanine. This alkaloid causes various symptoms of intoxication in high doses. However, if you remove the affected areas of the potato, you can cook and eat it as usual.
Eggplants also naturally contain solanine. Due to targeted breeding, dangerous amounts are rarely contained here, but to be on the safe side you should only eat ripe, dark purple fruits.
Rhubarb is one of the plants that contains a particularly large amount of oxalic acid. In addition to other symptoms of poisoning, this can promote the development of kidney and bladder stones. The leaves of the rhubarb contain the most oxalic acid, you should definitely not eat them. The sticks lose the toxic substance when cooked.
Elderberries contain the toxin sambunigrin, which releases hydrocyanic acid and can cause abdominal pain, nausea and vomiting. Again, you should only eat ripe fruit that has had the stems, leaves, and seeds removed. The fruits of the elder are only harmless after they have been boiled for at least 20 minutes.
Overall, few types of fruit and vegetables are inherently poisonous. For many, however, it depends on the right maturity and preparation.

If you don’t peel a zucchini, you not only save work and time: Read here about the advantages of peeling zucchini.

Do not peel zucchini – the skin is healthy

As with many other types of fruit and vegetables, the same applies to zucchini: the skin contains most of the vitamins. You also absorb important dietary fiber with the peel.

But it’s not just good for your health if you eat the shell. It also tastes better because the skin keeps the zucchini in shape as it heats. Without the skin, the vegetables quickly become mushy when they are boiled or fried. In addition, the pure pulp of the zucchini is not as aromatic as the skin.

So it would be a shame to throw the edible and particularly healthy part of a vegetable in the trash – especially since you have to do unnecessary extra work peeling it.

Also be careful with very bitter zucchini: If it tastes bitter, you shouldn’t eat it anymore. It’s rare, but if a zucchini tastes bitter, it contains too much curcubitacin, a toxic bitter compound. Neither cooking nor peeling helps against this substance, the zucchini is then no longer edible.

Pesticides on zucchini peel

Since the skin is eaten, you should pay particular attention to the origin of the vegetables: Zucchinis from organic farming are not treated with chemical-synthetic pesticides, but from conventional farming they are. Pesticides mostly remain on the peel. If you buy organic vegetables you ensure that the pesticides do not end up on your plate.

Also make sure that you buy zucchini seasonally and regionally. The zucchini season runs from July to October. During this time, the domestic zucchini are transported a comparatively short distance. Zucchini from distant countries, on the other hand, have long transport routes behind them, which means that significantly more greenhouse gases are emitted.

You can easily freeze zucchini and use it for cooking when it is not in season. You can do without plastic freezer bags – we will show you suitable alternatives.

Freeze zucchini: 12 months shelf life

Since zucchini is a seasonal vegetable, you should buy and freeze it from regional cultivation and organic quality during the season (June to October in Germany). So you can enjoy the summer squash all year round.

The courgettes will keep in the freezer the longest if you don’t cook them first:

Wash the courgettes and cut them into cubes or slices.
To keep your zucchini crunchy when defrosting, sprinkle them with a little salt. The salt draws moisture from the zucchini, making it easier to freeze.
After a few minutes, some water will form on the zucchini pieces. You can dab this off after five to ten minutes.
Then put the zucchini pieces in a screw-top jar and freeze them.
Frozen zucchini will keep for at least 12 months and retain their flavor.

Freezing zucchini cooked: what do you have to pay attention to?

Freezing cooked zucchini is especially worthwhile if you overcooked it. Then you don’t have to throw away the leftover zucchini. Again, you can put the zucchini in a screw-top jar to freeze them.

To prevent the zucchini from getting mushy when defrosting, you should defrost them very slowly at room temperature. Then heat them up briefly in a saucepan or pan.
