All asparagus fans can breathe easily. The popular seasonal vegetable was tested by the Federal Office for Consumer Protection and the results are encouraging: most asparagus samples are free of pesticides.

The royal vegetable

With spring comes the asparagus season. Since asparagus is so popular, the quality is strictly monitored in Germany and regular checks are carried out by the supervisory authorities in the federal states.

As in previous years, the results this year are again pleasing. The Federal Office for Consumer Protection and Food Safety (BVL) has published data on pollution.

The investigations showed that asparagus is one of the least contaminated vegetables and is virtually free of pesticides.

Little strain on asparagus

As early as 2016, the Federal Office for Consumer Protection found residues of pesticides in only four of the 502 asparagus samples examined (the stipulated maximum level here is 0.8 percent). In 2015 not even in any of the 350 samples.

The inspectors also found multiple residues extremely rarely. Only 3 percent of the inspected asparagus showed residues, compared to an average of around 30 percent.

In contrast to other types of fruit and vegetables, where ten or even more active substances were sometimes found in one sample, a maximum of five active substances were detectable in asparagus samples from 2010 to 2016, reports the BVL.

Strict controls

Asparagus is very often tested for pesticides and is sometimes even one of the most frequently tested vegetables. Since the German asparagus is the most commonly offered on the market, the quality controls are very regular.

The news that asparagus is hardly contaminated by pesticides is all the more gratifying. Even ahead of Germany, China is one of the largest growing countries for asparagus, followed by Peru and Mexico.

Lead levels have dropped significantly

Overall, the lead content in asparagus is very low compared to previous studies. In most samples, no or only very small amounts of lead, mercury, cadmium, arsenic, nickel, and aluminum are detected.

In the case of lead, in particular, exposure has decreased in recent years.

Hardly any perchlorate pollution

During the controls, the asparagus was also checked for perchlorate. The intake of salt inhibits iodine absorption in the body and can thus impair the metabolism of the thyroid gland. Because of this, intake of this salt should be minimized.

But the all-clear is given here too, because only two of the 294 asparagus samples showed a quantitatively determinable perchlorate content, which was clearly below the applicable European reference value, according to the BVL.

Enjoy asparagus without hesitation

The popular vegetable is therefore as good as free of any pesticides and is, therefore, one of the vegetables with the lowest levels of pollution.

Nothing stands in the way of enjoying asparagus and delicious, healthy, and low-calorie dishes can be conjured up from the white and green spears.

Asparagus is considered the most popular spring vegetable because it not only tastes delicious, but is also an absolute nutrient bomb. But what is the difference between green and white asparagus and which variety is healthier? Here are the answers.

White or green – that’s the difference between asparagus

White asparagus grows underground and is also harvested underground. Its green counterpart grows above the ground and forms chlorophyll as soon as it stretches its head out of the ground towards the sun. Hence the green color.

In addition, green asparagus does not taste quite as mild and fine as white, but has a more spicy taste.

Since white asparagus has to be pricked, which involves a lot more effort, it is usually a bit more expensive. Green asparagus only has to be cut off.

How healthy is asparagus?

Asparagus consists of 90 percent water and is therefore very low in calories and fat-free. The fat content is only about 0.3 percent. It’s 0.47 percent carbohydrate and just over 2 percent protein, which is where “most” of the calories come from.

The popular vegetable also contains many important vitamins (A, B, C, E, K) and many valuable minerals such as sodium, potassium, calcium, magnesium, phosphorus and iron.
The high potassium content and the asparagine, which stimulates kidney function, have a draining effect and there can be a strong smell of urine after consumption.

White and green asparagus: which variety is healthier?

Green asparagus is a bit healthier because it contains more vitamin C, folic acid and also more B vitamins than its white counterpart.
In addition, you don’t have to peel it, just remove the woody ends before cooking.
In the end, both varieties are very healthy, which is why only personal taste should play a role in the selection.

Asparagus and gout – when does asparagus become unhealthy?

However, according to the Federal Center for Nutrition, eating large amounts of asparagus can trigger gout attacks, which is why some people should consume the delicious vegetable with caution. It contains many purines, which are converted to uric acid in the body. If there is more uric acid than the kidneys can process and excrete, the uric acid level in the blood will be too high, which in turn can lead to deposits, especially in finger and toe joints.

This creates pain and swelling in sufferers, which are the symptoms of gout. If you have kidney problems or even kidney stones, it is better to consume asparagus in smaller amounts. In moderation this is not a problem, because the quantity makes the poison. Incidentally, the largest proportion of purines is in the asparagus head, so if you want to be particularly careful, you can remove it beforehand – but who wants to do without the best part?

Ultimately, both white and green asparagus are super healthy and should definitely be taken advantage of and enjoyed during asparagus season.

Asparagus is often said to have a certain complexity. Cooking asparagus properly is not difficult at all.

Tips for buying asparagus

The sticks must be bright and firm, the tips should be closed. If you rub two spears of asparagus together, they should squeak with freshness!

The best thing to do is to start thinking about it when you go shopping: local asparagus will be available from mid-April. Freshly cut, without long transport routes, asparagus simply tastes best. Check interfaces when shopping: They must not be dry or even moldy and juice should come out when you squeeze them. The sticks must be bright and firm, the tips should be closed. If you rub two spears of asparagus together, they should squeak with freshness!

Store asparagus properly

If you don’t want to overcook your freshly bought stick vegetables right away, you can wrap them in a cloth (e.g. tea towel) moistened with lemon water and keep them in the vegetable compartment of your refrigerator for a few days (max. 3). If you want to freeze asparagus, you should prepare it ready to cook beforehand, i.e. cut off any woody ends and peel the rest. It is not necessary to blanch asparagus before freezing. Do not thaw the frozen asparagus before preparation, but place it directly in the boiling water.

Peel the asparagus properly

Before preparation, wash the asparagus briefly, pat dry, and peel with a vegetable or asparagus peeler. To do this, place the asparagus on your forearm and hold it with all your fingers except your little finger. Then use an asparagus peeler to peel from the bottom of the tip to the end of the stalk; meanwhile, turn the asparagus with your fingers. Green asparagus does not have to be peeled that far, the lower third is usually enough. With white asparagus, it pays to peel a little more generously, preferably starting under the head. Don’t throw away the asparagus shells! You can boil them for an aromatic asparagus broth that can be used to infuse creamy soups and sauces.

More about asparagus

Asparagus (lat. Asparagus Officinalis) belongs to the lily family. The perennial shrub grows to a height of about 1 m and has a woody rootstock. The asparagus buds begin to sprout at the top of the root. In spring from a soil temperature of 15 °C, the rhizome puts out many finger-thick sprouts that are white in color and turn green as soon as they come out into the open.

White and variegated asparagus

White asparagus has a typically fine asparagus aroma, is very tender, and has fewer bitter substances than other asparagus. The rungs are protected from the sunlight by mounds of earth to keep them white. White asparagus is cut 20 to 25 cm below the ground.

Green asparagus is cultivated without ridges, is tender and fine, but has a more intense taste. It is becoming increasingly popular and cultivated more and more often. Today, the proportion of green asparagus is over ten percent.

Purple asparagus contains more anthocyanins, which turns it purple. It originally comes from Italy and therefore needs more sun and warmth. Occasionally you can buy the slightly sweeter purple asparagus in Austria, more towards the end of the season.

That’s why you should eat asparagus

Asparagus consists of 90% water, the rest is valuable vitamins, minerals such as potassium, and hardly any calories (20 kcal per 100 g). It also scores vitamins A, C, and folic acid.

It’s a good thing that asparagus grows in spring, because it stimulates the metabolism, supports the liver and kidneys, and has a draining effect. However, people with a tendency to have kidney stones and high blood uric acid levels should be more careful with asparagus. Asparagus gets its typical taste from aspartic acid, which is important for the urea cycle and stimulates kidney function. After eating asparagus, the urine gets a peculiar smell.

Harvesting asparagus is manual work!

From mid-April to at the latest on St. John’s Day on June 24th, asparagus is harvested, as the harvest of the spear is known in technical jargon. Incidentally, asparagus can only be harvested by hand!

If you want to eat asparagus raw, you should use thin spears. In this article you will find out what else you should pay attention to and the advantages and disadvantages of raw asparagus.

April to June is asparagus time in this country: this is when the healthy vegetables end up on the plates of asparagus lovers, often several times a week. Cooked asparagus is the most popular, but you can also roast or otherwise prepare asparagus.

What many people don’t know: You can also eat asparagus raw. We tell you what is important.

Eating raw asparagus: edible and healthy

Yes, you can also eat asparagus raw. The raw vegetable is neither poisonous nor indigestible. Raw asparagus is said to be particularly healthy:

100g of raw asparagus contains 2.2g of protein, 2g of fiber and virtually no fat. With a water content of 93 percent, asparagus in its raw form can help hydrate the body.
In addition, asparagus provides important minerals: 100 g of raw asparagus contain 24 mg of calcium, 14 mg of magnesium and 202 mg of potassium.
Of particular interest: raw asparagus is also rich in folate (52 µg per 100g), vitamin K (41.6 µg per 100g) and vitamin C (5.6 mg per 100g). In addition, asparagus provides vitamin E (1.13 mg per 100g) and vitamins B1 and B2. Many vitamins are heat-sensitive and would be largely lost during cooking.
A 2011 study confirms this. The scientists found that the longer asparagus is heated, the more nutrients are lost. The vegetables were even blanched – a preparation method that is considered gentle.
Asparagus has been shown to have a diuretic effect. This effect is said to be stronger with raw asparagus than in its cooked form – but we could not find any scientific evidence for this.
Note: It is of course not the case that cooked asparagus no longer contains any beneficial nutrients, as not all nutrients are heat-sensitive. Especially when it comes to vitamin C, vitamin B1 and vitamin B9, asparagus performs better in its raw form.

On the other hand, asparagus also contains ferulic acid, which according to the BBC, our body can only access well after heating. Ferulic acid has an antioxidant effect and can thus protect against oxidative stress. From a health point of view, it is therefore worth not always eating asparagus raw and instead varying the preparation methods.

Raw asparagus: taste and purchase recommendation

Raw asparagus does not differ from the cooked variant in terms of nutrients, but also in terms of taste: The typical asparagus aroma, which lovers appreciate so much, only develops under the influence of heat and is therefore missing in the raw preparation. Fresh asparagus is particularly juicy when raw and, in addition to the slightly nutty aroma, is also reminiscent of pea pods. Raw asparagus also tastes slightly sweet, which makes it particularly appetizing.

If you want to eat asparagus raw, you should prefer thin spears. The thicker the asparagus, the tart and bitter it tastes. In addition, asparagus tastes better the fresher it is. This is why regional asparagus is always ahead of imported goods.

You can eat both green and white asparagus raw. From an ecological point of view, however, green asparagus is more advisable, since white asparagus must be protected from the sunlight with plastic films when growing.

In general, we therefore recommend that you buy green asparagus regionally and seasonally. Organic quality is also important, as conventional asparagus is often contaminated with pesticides.

Prepare asparagus raw – it’s that easy

You always have to peel white asparagus. But don’t just throw away the peel: you can use it to prepare a delicious asparagus peel soup. If, on the other hand, you decide to use green asparagus, you should definitely leave the peel on. Most of the vitamins are just under the skin.

You can easily prepare raw asparagus:

Wash the asparagus.
If the lower end is purple-whitish and hard, you should definitely peel this part and cut off the mostly dried end.
If the asparagus is green all the way through, you only need to cut off the lower end a finger’s width. Alternatively, you can also break the asparagus – it usually breaks directly above the end that is too tight.
If the asparagus spears are very thick and the skin feels hard, peel only the bottom third of the asparagus.
You can then use the asparagus in any recipe.

You can eat the asparagus prepared in this way raw, for example, as follows:

Marinated asparagus: Cut the raw asparagus into fine strips and leave them in a marinade for about 20 minutes. In a separate article, we present five recipes for delicious marinades. You can serve the asparagus marinated in this way with fresh lettuce and, if necessary, some cheese.
Asparagus sticks with dip: You can use whole or halved asparagus stalks for dipping. This goes well with homemade hummus or pesto, for example. Also, try our vegan dips.
Mushroom and asparagus salad: cut into fine strips, you can use raw asparagus with fried mushrooms, tomatoes, and a delicious dressing made from olive oil, balsamic vinegar, honey, salt and pepper to create a delicious salad. You can find the whole recipe in our How to Prepare Green Asparagus article – just skip the step of frying the asparagus.
Tomato and asparagus salad with mozzarella: A raw vegetable salad made from asparagus, cherry tomatoes, spring onions and mozzarella cheese is also delicious. Serve with vinaigrette dressing.
Asparagus and strawberry salad: In this country, asparagus and strawberries are in season at the same time. That’s why you can use these two ingredients to prepare a delicious, special kind of salad. Just follow our asparagus recipe and skip the step of frying the asparagus.
Smoothie with asparagus: Those who like to experiment with asparagus can also prepare a smoothie with asparagus. However, you should start slowly at first, as the asparagus taste can quickly become too intense if the quantities are too large.
Tip: Try eating raw ginger – it is particularly rich in vitamins and nutrients. The same applies to many other foods: You can also eat zucchini raw, for example.

Peeling green asparagus is quick, but in many cases it is not necessary. We will show you what you have to consider and how to properly process green asparagus.

In contrast to white asparagus, green asparagus are not pricked as soon as the head sticks out of the ground, but continues to grow in the sun. That is why green asparagus does not need black foil. Sunlight gives it its green colour, plus more healthy vitamins and a stronger flavor than white asparagus.

Since green asparagus is less expensive to grow and harvest than white, it is usually a little cheaper. It is also less complicated to prepare. Because of its thin skin, you usually don’t have to peel green asparagus! If you buy it seasonally, you can also be sure that its growth has not been artificially accelerated by heaters or thermal foils. So there is a lot to be said for accessing seasonal green asparagus.

Note: The use of foil when growing white asparagus makes it a real problem for the environment. Not only does the film pollute the environment during its production and disposal, it also destroys the natural habitat of many endangered bird species.

Peel, cut, or break green asparagus?

Whether or not you need to peel green asparagus depends on how it was harvested. If the bottom third is purple-whitish and hard, be sure to peel that part and cut off the dried ends. The white rim has not yet seen sunlight and will still be very firm and brittle after cooking.

When the asparagus is green all the way through, just cut off the end an inch. You should never peel the green and soft asparagus skin. Most of the vitamins are just under the skin. If the asparagus spears are still very thick and the skin feels hard, peel only the lower third.

You can also break green asparagus instead of cutting them. Since the inedible part cannot be broken off, the asparagus will break off above the woody end. So you don’t have to use a peeler or knife and you can prepare your asparagus quickly and easily. For this, the asparagus must be very fresh and crisp.

Green asparagus tastes best fresh from the market. If necessary, you can wrap it in a damp cloth in the fridge and keep it fresh for a few days.

In order to avoid long transport routes and to protect the environment and climate, you should only buy asparagus regionally and seasonally. To be sure your asparagus is chemical-synthetic free, buy organic asparagus.

Boil green asparagus

The easiest way to prepare green asparagus is in boiling salted water. The cooking time is significantly shorter than with white asparagus and, depending on the thickness, is only around eight minutes.

In order for the asparagus to keep its bright green color, you can also add some white vinegar or lemon juice to the cooking water and shock the asparagus with ice water when they are done.

Or you can simply fry green asparagus in a pan with some cooking oil or fat. Cut into fine pieces, it is cooked within five minutes.

Of course, asparagus can also be grilled or put in the oven as an asparagus casserole. Green asparagus soup tastes particularly delicious. You can also use the woody ends that you removed earlier and boil them as a broth for the soup. In this way you use every gram of your precious asparagus and there are no leftovers that you have to throw away at the end.

You should never throw away asparagus peel, because you can use it to cook a tasty asparagus soup. In our simple recipe, we show you how easy it is to cook a delicious asparagus soup with just a few ingredients.

Cooking asparagus soup from asparagus peels – the ingredients

It is best to buy white asparagus during the asparagus season from mid-April to June. Make sure that the asparagus comes from the region, as long transport routes are bad for the climate. In addition, you should only use organic asparagus, since conventional asparagus spears are treated with chemical-synthetic pesticides. Organically grown asparagus is usually a bit more expensive, so you should definitely use the asparagus skin as well – for example for an asparagus soup. Because the peel is also very aromatic and you avoid wasting food. With three small changes to the recipe, you can also prepare the asparagus soup vegan.

For two servings you need the following ingredients:

Peel of 500 g white asparagus
1 tsp sugar
1 tsp lemon juice
1/2 tsp salt
10 g butter or vegan margarine
2 tbsp flour
optionally 1 egg yolk
50 g whipped cream or vegan cream
Pepper, nutmeg and chervil to taste

Recipe: cook asparagus soup from bowls

Wash the asparagus shells.
Put the peels in a saucepan with the salt, sugar and lemon juice and add enough water to cover the peels.
Bring the water with the peels to a boil and then let them simmer for about ten minutes.
Pour the soup through a sieve and collect the liquid in a saucepan. The asparagus shells are now boiled and you can dispose of them in the organic waste.
Then, in a tall saucepan, prepare a roux by heating butter in a separate saucepan, adding the flour and mixing well.
Then gradually add the asparagus peel water to the roux. Be sure to stir regularly and vigorously to avoid lumps later in the soup.
Season the soup with a little salt and then briefly boil it again.
Take the pot off the stove, mix the egg yolks and cream together and add both to the soup.
Tip: Asparagus contains bitter substances, especially under the skin. Therefore, do not cook the peel for too long. This way you avoid too many bitter substances going into your soup.

You can serve the soup now and serve it with chervil or grilled asparagus, for example. However, you should not boil the soup again, otherwise the egg would clump together.
