Chokeberry / Aronia: Effects, Application, and Quality

What is Aronia melanocarpa? Botanical Profile and Origin

The aronia berry, scientifically known as Aronia melanocarpa, is often simply referred to as chokeberry in English-speaking countries. It belongs to the rose family (Rosaceae), which also includes many of our most popular fruit varieties such as apples, pears, and cherries. The fruit is a small, deep black-purple pome that impresses with its intense color and tart taste.

Aronia is originally native to eastern North America, where it prefers to grow in moist forests and wetlands, from Newfoundland in the north to Florida in the south and west to Ontario and Minnesota. Its robustness to various soil and climate conditions has made it a popular cultivated plant, which is now successfully grown in many temperate regions of Europe, especially in Eastern Europe.

The cultivation and harvesting of aronia are relatively straightforward. As a resilient, deciduous shrub, it is easy to care for and is often valued not only for its healthy fruits but also for its ornamental value. The berries typically ripen in late summer to early autumn, usually between August and September. Their deep black color and slightly softer texture indicate the optimal harvest time. Harvesting is done manually or mechanically, depending on the size of the cultivation.

The Power of the Aronia Berry: Focusing on Secondary Plant Compounds

The reputation of the aronia berry as a "superfruit" is not unfounded. It is a true treasure trove of valuable ingredients, especially secondary plant compounds, which are responsible for its intense color and potential health benefits.

• Polyphenols: Aronia is known for its exceptionally high content of polyphenols, primarily anthocyanins and proanthocyanidins. These compounds are potent antioxidants.
  • Anthocyanins: These pigments give the aronia berry its characteristic deep black color and are powerful antioxidants. Dominant here are cyanidin-3-galactoside, cyanidin-3-arabinoside, cyanidin-3-glucoside, and cyanidin-3-xyloside.
  • Proanthocyanidins (condensed tannins): These oligomeric and polymeric forms contribute to the tart taste of the berry and are also known for their strong antioxidant and anti-inflammatory properties.
• Phenolic Acids: Chlorogenic acid, neochlorogenic acid, and caffeic acid are also present in aronia.
• Flavonoids: Quercetin, rutin, and epicatechin supplement the rich spectrum of bioactive compounds.
• Vitamins: Aronia provides significant amounts of vitamin C and vitamin K, as well as some B vitamins.
• Minerals: Potassium, calcium, magnesium, iron, and zinc contribute to mineral supply.
• Dietary Fiber: The berry is also a good source of dietary fiber, which plays an important role in healthy digestion.

This unique combination of ingredients makes the aronia berry a valuable component of a health-conscious diet.

Aronia in History: A Journey from North America to Europe

Unlike some other plants, Aronia melanocarpa does not have a long tradition in European folk medicine, Ayurvedic teachings, or Traditional Chinese Medicine (TCM), as it is not native there. Its history as a valuable plant begins on its original continent.

In North America, various indigenous tribes, including the Ojibwe and Cree, used aronia berries as an important food source. They were eaten fresh as well as dried and often mixed with other foods such as pemmican. The indigenous people also recognized some medicinal properties of the berries. They were used to relieve colds, fever, or as a general tonic. Infusions were prepared from dried berries, which were used for digestive problems or as a blood-strengthening agent.

Aronia only gained widespread use and popularity in Europe in the 20th century, particularly in Eastern Europe and Russia. There, it was intensively cultivated and quickly gained a reputation as a health-promoting fruit. It was used in folk medicine to support cardiovascular health and boost the immune system, often in the form of juice, jam, or dried berries. In these regions, aronia now has a high cultural significance and is regarded as a "superfruit" for health and vitality. In Germany, its awareness and popularity have recently increased significantly as part of the general interest in healthy and natural foods.

What Science Says: Aronia in the Focus of Research

The abundance of bioactive compounds in the aronia berry has attracted the interest of scientists. Numerous in vitro, animal, and human studies are exploring its potential health effects, focusing on antioxidant, anti-inflammatory, cardiovascular, and metabolic benefits.

Clinical Studies from EU/G7 Countries (Selection):

Cardiovascular Health (Blood Pressure & Blood Lipids)

Metabolic Health (Blood Sugar Regulation)

Antioxidant and Anti-inflammatory Effects

Immune System Support

Systematic Reviews and Meta-Analyses:

• Olas (2018), Poland: "Aronia melanocarpa as a Potential Source of Bioactive Compounds for the Prevention and Treatment of Cardiovascular Diseases." This review summarizes numerous studies and highlights Aronia's positive effects on blood pressure, lipid profiles, and endothelial function, mainly due to its antioxidant and anti-inflammatory properties.
• Qin et al. (2017), China: "Effect of Aronia melanocarpa on blood pressure: A systematic review and meta-analysis of randomized controlled trials." This meta-analysis concluded that Aronia significantly lowers systolic and diastolic blood pressure, especially in individuals with metabolic syndrome.
• Kulling and Rawel (2008), Germany: "Chokeberry (Aronia melanocarpa)—A review on the composition and potential health effects." An early, comprehensive overview of the chemical composition and emerging health benefits that laid the groundwork for further research.

In Vitro and Animal Studies:

Numerous studies confirm the potent antioxidant activity of aronia in cell cultures, protecting against oxidative damage. Animal models showed that aronia extract reduces inflammation, improves insulin sensitivity, protects the liver and kidneys from damage, and even exhibits anticancer potential by inhibiting cell proliferation and inducing apoptosis in various cancer cell lines. However, these promising results need to be confirmed in human studies.

Assessment of Evidence Quality:

• Moderate: For cardiovascular health (blood pressure, lipid profile, endothelial function) and antioxidant/anti-inflammatory effects. Several randomized, placebo-controlled human studies support these benefits, although larger, multicenter studies would further strengthen the evidence.
• Preliminary: For blood sugar regulation, immune support, gut health, and anticancer properties. Human data are emerging but often come from smaller studies or require more extensive replication. In vitro and animal studies provide strong preliminary evidence for these areas.

Aronia and European Legislation: Safety and Classification

As a consumer, it is important to know how products like the aronia berry are legally classified and regulated in the European Union, and particularly in Germany. This ensures product safety and transparency.

EFSA (European Food Safety Authority) Health Claims:

According to current information, there are no specific, authorized health claims for Aronia melanocarpa or its components under Regulation (EC) No. 1924/2006. Various applications for health claims regarding Aronia's antioxidant properties, cardiovascular health, and immune function have been submitted in the past but were either rejected due to insufficient evidence or withdrawn. This does not mean that Aronia is ineffective, but rather that the scientific evidence submitted to the EFSA at the time of evaluation did not meet the strict requirements for substantiating a specific health claim. General statements about "antioxidant properties" or "polyphenol content" are often used in marketing but are not specific health claims authorized for Aronia.

EU Novel Food Status:

Aronia melanocarpa berries and their traditional preparations (e.g., juice, dried berries) are not considered novel foods under Regulation (EU) 2015/2283. This is because they have a documented history of safe consumption in the EU before May 1997, particularly in Eastern European countries. However, highly concentrated or novel extracts or specifically isolated compounds from Aronia might require novel food authorization if they do not have a documented history of consumption in the EU before the cut-off date.

Maximum Permitted Dosages in Food Supplements (EU):

There is no harmonized, EU-wide maximum permitted dosage specifically for Aronia melanocarpa in food supplements. Member States may have national guidelines or restrictions. Generally, food supplements containing Aronia fall under general food law, and manufacturers are responsible for ensuring the safety of their products and ensuring that dosages do not pose risks to consumers.

Positions of the German BfR (Federal Institute for Risk Assessment):

The Federal Institute for Risk Assessment (BfR) generally considers aronia berries and their juice to be safe for consumption as food. Although the BfR has not issued specific maximum dosage recommendations for Aronia in food supplements, it emphasizes that food supplements should not replace a balanced diet and that highly concentrated preparations from plant substances should be consumed with caution. The BfR generally holds the view that products must be safe and consumers must not be misled by unsubstantiated health claims.

Legal Classification in Germany:

In Germany, Aronia melanocarpa products are predominantly classified as foodstuffs or food supplements. This classification applies to juices, dried berries, powders, and extracts that do not meet the definition of a medicinal product. The distinction from traditional herbal medicines is clear here, as Aronia is not registered as such in Germany.
