New study: does aronia juice protect against coronaviruses?


There have been reports of drugs and miracle drugs that could help against the coronavirus. Chokeberry juice can be bought in many markets – but how effective is it really?

Aronia juice is said to be effective against coronaviruses – a study suggests. But before consumers go to the supermarket and pull out their wallets, they should take a critical look. Consumer advocates warn: some recommendations for protection against coronaviruses not only weigh consumers in a false sense of security, but can ultimately do more harm to health than good.

Gargle aronia juice against Corona?

There are reports on the Internet about a study that shows that aronia juice has an anti-viral and anti-virus effect Coronavirus wants to have discovered. The Institute for Molecular Virology at Ulm University Hospital, the laboratory of Prof. Dr. G. Enders MVZ in Stuttgart and CogniVerde GmbH in Groß-Umstadt.

Of the juice According to the research team, the aronia berry (Aronia melanocarpa) can inhibit the docking process of the virus in the oropharynx. The study authors recommend gargling the juice of the aronia berries against the coronavirus and then swallowing it.

Beware of supposed miracle cures against Corona

Consumer advocates warn against unreservedly believing such recommendations – and thus possibly lulling yourself into a false sense of security.

“Since these are only the first laboratory tests of certain ingredients in the aronia berry against viruses, it is far too early to give recommendations for action,” says consumer advocate Armin Valet. “What is suggested here cannot simply be transferred to humans without conducting clinical studies. Efficacy has not yet been proven. This is still basic research.”

Do dietary supplements help against corona?

The consumer advocate advises to be skeptical of new studies, advertised food supplements and other supposed Corona miracle drugs such as superfoods. And not just in terms of effectiveness. Some recommendations are associated with health risks.

“Recommendations circulating on the Internet to take MMS (Miracle Mineral Supplement) to protect against the coronavirus are really dangerous. The agent, also known as CDL (chlorine dioxide solution), is a disinfectant and is used to bleach textiles. A real health risk!” warns Valet.

“Your health benefits more from a healthy and balanced diet and regular exercise than from highly concentrated vitamin preparations or various advertised food supplements.”

Beware of a false sense of security

In addition, such agents can easily convey a false sense of security. “There are currently no juices, powders or capsules that have been proven to help against coronaviruses. Possible modes of action have so far only been based on assumptions or experiments,” explains Valet.

“The best protection against corona is still offered by the corona protective measures and the corona vaccination. Dietary supplements and superfoods such as aronia can neither cure diseases such as Covid-19 nor protect against them,” emphasizes Valet.

Proof of efficacy is lacking for dietary supplements

Food supplements are not medicinal products. You do not need a license. They are only reported to the Federal Office for Consumer Protection and Food Safety. You do not have to provide proof of effectiveness and also do not have to present clinical studies. That means: Consumers dig deep into their own purse for many preparations – and wait in vain for the hoped-for benefit.

“Nutritional supplements can, as the name suggests, only supplement food. Nutritional supplements can be useful if there is a medically confirmed deficiency in certain vitamins, minerals or trace elements. A healthy person who eats a healthy and balanced diet does not need such preparations.” says Valet. “If you still want to drink a glass of aronia juice a day, it probably won’t do you any harm Berry contain plenty of vitamins. Just don’t expect protection against coronaviruses. ”

What the aronia berry can do for your health

In addition to vitamin C (13.7 mg per 100 g), aronia berries also contain folic acid (20 µg), zinc (0.15 mg) and iron (0.9 mg). “Aronia berries are also rich in secondary plant substances such as flavonoids and phenolic acids. Above all, the antioxidant red plant pigments anthocyanins (349 milligrams of anthocyanidins per 100 grams) and proanthocyanins are worth mentioning,” says graduate ecotrophologist Silke Restemeyer from the German Society for Nutrition (DGE). Anthocyanins are also found in blueberries, blackberries and red cabbage, among other things.

According to the nutrition expert, you shouldn’t expect too much from the aronia berry. “So far, in-vitro studies, animal experiments and, in some cases, intervention studies on humans have shown that the berries have antioxidant, anti-inflammatory, liver-protective and anti-carcinogenic effects. None of these claims have been scientifically proven,” says Restemeyer.

Whether aronia berries actually prevent cancer, detoxify the body in the case of liver and kidney ailments, relieve indigestion, regulate blood pressure and cholesterol levels and have a beneficial effect on the cardiovascular system and immune system effect remains unexplained for the time being.

Chokeberry juice: less is more

If you still want to drink aronia juice, the nutrition expert has a tip for you: “The tannins it contains can cause abdominal pain in sensitive people. The tolerance is often better if you eat or drink dried aronia berries or pure aronia juice with or after a meal.”
