The blackcurrant, whose scientific name is Ribes nigrum, is the fruit of a shrub native to Asia and Europe. It’s also known as black sarsaparilla. It belongs to the same family as the red and white currant, but its raw consumption is less frequent than the other varieties.

It grows in clusters formed by small berries with smooth and dark skin. Its taste is acidic and astringent. It could be said that these berries have a strong and unpleasant flavor, but as they ripen, they acquire a certain sweetness. Anyway, they boast several positive health effects.

In the 17th century, a document called “the admirable properties of blackcurrant” was published in which their medicinal benefits were praised. Since then, these berries have been known as an ally against inflammatory skin diseases associated with aging.

The nutritional value of blackcurrant berries

The blackcurrant is low in calories, making it ideal for slimming diets or weight maintenance. This fruit provides good amounts of fiber, a nutrient that improves intestinal transit. It also stands out for its high content of vitamin C.

In his book The Cultivation of Currants, the engineer Anibal Caminti  states that every 100 grams of blackcurrants provide the following:

  • Water: 89 milligrams.
  • Calories: 54
  • Protein: 1.70 milligrams.
  • Carbohydrates: 13 milligrams.
  • Crude fiber: 4.0 milligrams.
  • Vitamin A: 6 milligrams.
  • Thiamine, B1: 4 milligrams
  • Riboflavin, B2: 3 milligrams
  • Niacin: 2 milligrams
  • Vitamin C: 444 milligrams
  • Calcium: 7.5 milligrams
  • Phosphorus: 5 milligrams
  • Iron: 11 milligrams

Blackcurrants are also abundant in antioxidants, which have a favorable impact on health and vitality. The most prominent are the following:

  • Proanthocyanidins: These compounds are precursors of anthocyanins, which give the red, white, or black color to currant berries. The most common are delphinidin and cyanidin.
  • Vitamin C is present in 444 milligrams per 100 grams of this little fruit. Vitamin C is a powerful antioxidant that neutralizes free radicals and immune system functions.
  • Flavonoids: These berries also contain flavonoid derivatives such as quercetin, myricetin, and kaempferol.

The possible benefits blackcurrant berries

As a review reported in The Journal of Food Science exposes, blackcurrant is an interesting source of phytochemicals with antioxidant, antimicrobial, and anti-inflammatory effects. Hence, much of its benefits are related to these effects.

Let’s take a closer look.

1. Blackcurrants are good for your kidney health

The presence of antioxidants and anti-inflammatories in blackcurrants may prevent chronic kidney disease. According to a publication in the European Journal of Clinical Nutrition, the extract of this fruit helps to inhibit the formation of kidney stones. It protects the excretory system from infections and inflammation.

In the same document, specialists explain that current extract, juice, and tea increase the pH of urine, which makes it more alkaline. Incidentally, it stimulates the elimination of oxalic acid and citric acid when they accumulate in excess.

2. They help reduce and prevent inflammation

The consumption of anti-inflammatory foods such as blackcurrants helps prevent inflammatory diseases. Some of these are liver disease, kidney disease, heart disease, and neurodegenerative diseases (such as Alzheimer’s and dementia).

In the journal Nutrients, they refer to the anthocyanins present in blackcurrants. This study determined that blackcurrant extracts can suppress the activity of pro-inflammatory components in the immune system of laboratory animals.

On the other hand, blackcurrant seed provides omega-6 fatty acids, gamma-linolenic acid, or GLA. According to another study, this berry can help decrease inflammation in the body. Thus, both anthocyanins and GLA found in black currant may reduce pain and inflammation in joints and muscles.

3. Blackcurrent berries help strengthen your immune system

Vitamin C and anthocyanins can strengthen the immune system. In addition, a doctoral thesis study in rats found that gamma-linolenic acid may have an immunomodulatory effect.

On the other hand, in a group of healthy older adults supplemented with black currant seed oil, a moderate immune-boosting effect attributable to the presence of the fatty acid GLA was found.

4. They help your digestion

Animal studies found that blackcurrant extract may have an antispasmodic effect on the gastrointestinal tract. It’s possible that these qualities have to do with its flavonoid content. This could even be a reason to declare it as a digestive food.

Other research has also noted the antispasmodic effect of black currant. The presence of flavonoids in the fruit and leaves inhibit spasms in the stomach and intestines. Its astringent effect makes it helpful in cases of diarrhea.

5. Blackcurrant berries promote visual health

Research published in the Journal of Ocular Pharmacology and Therapeutics found that regular consumption of blackcurrants can help prevent vision loss or symptoms associated with glaucoma.

The study highlights that anthocyanins increase blood flow in the optic nerves and eyes. In addition, they can improve diabetic retinopathy and retinal vein and retinal artery occlusion.

6. They help control Type 2 diabetes

The research concluded that the different anthocyanins in blackcurrants, such as cyanidin, delphinidin, and peonidin, can improve insulin sensitivity in people with Type 2 diabetes.

On the other hand, the journal Nutrients refers that anthocyanins can inhibit the activity of enzymes that degrade carbohydrates. In this way, the digestion of carbohydrates as a source of glucose is slowed down, and unexpected spikes in blood sugar levels are prevented.

7. They promote good heart health

Blackcurrant consumption is also good for heart health. Research on the effect of anthocyanins on blood cholesterol control revealed that diets rich in this pigment lower total cholesterol levels and “bad” or LDL cholesterol. At the same time, it was associated with an increase in “good” or HDL cholesterol.

In another study, pure blackcurrant juice was analyzed as an antioxidant drink. This study found that drinking it for one week helped prevent body fat oxidation.

In turn, the Journal of Nutrition blackcurrant powder was reported to increase heart blood flowand decrease overall peripheral resistance.

8. Blackcurrant berries promote skin health

A group of skin health specialists found that a polysaccharide from blackcurrants has anti-inflammatory effects. This allows controlling the production of pro-inflammatory compounds in the immune system.

In turn, the fatty acids in the seed of this fruit contribute to suppressing inflammatory mediators in the skin. For this reason, the magazine American Journal of Clinical Nutrition recommends applying blackcurrant seed oil to care for and nourish the skin.

9. They’re beneficial in the prevention of neurodegenerative diseases

The potential of blackcurrants as an antioxidant has been reported in various studies, with a reported 65% inhibition of lipid peroxidation in the body. In laboratory animals, the protective role of blackcurrants on the central nervous system was even observed.

It appears that blackcurrants contribute to decreasing neuroinflammation, improving memory, learning, and cognitive abilities. In addition, since they inhibit the action of free radicals, they act as a protector against diseases such as Alzheimer’s and Parkinson‘s.

Within the framework of a healthy and varied diet, the consumption of blackcurrants can contribute to the prevention of chronic diseases.

Where to find blackcurrant berries and how to consume them

Blackcurrants can be found in supermarkets and greengrocers. They’re also available in other forms, such as oils, syrups, smoothies, puddings, liqueurs, tablets, capsules, and powder.

They’re also present in certain products. For example, because of their acidic and astringent taste, they’re often used in the following:

  • Jams
  • Vinaigrettes
  • Jellies
  • Ie cream
  • Yogurt
  • Salads
  • Blackcurrant cream (a recipe appreciated in France)
This berry has a high content of pectin-like fiber and other properties that make it a good choice to enhance certain recipes, especially those that require spicy sweetness.
Some recommended doses according to the book of medicinal herbs are as follows:
  • A glass of blackcurrant juice a day
  • 5 to 10 milliliters of blackcurrant syrup per day
  • About four capsules of 250 milligrams per day, twice a day
  • 1 to 2 teaspoons of leaves, three to four times a day

The blackcurrant is one of the berries with the highest concentration of nutrients. Its antioxidant, vitamin C, and fatty acid content enhance its health benefits. In addition, it’s versatile in gastronomy since it has different forms of consumption, such as jams, combined with yogurts, ice cream, juices, etc.
