Raspberry

Raspberries are one of the most effective drugs against cancer and obesity, and berries that are fully ripe can have 2 times more beneficial substances. And this is not all the amazing discoveries that scientists have made regarding this sweet berry. Read on and you will find out that raspberries can treat not only colds.

General characteristics

Raspberries are a shrub from the Rosaceae family, the fruits of which are among the three most consumed berries in the world. There are more than two hundred types of raspberries and three main groups: red, black and purple.

The color of red raspberry is already clear from the name, although the shades may differ significantly. Among all varieties grown commercially, the European red raspberry is the most popular. Black raspberries are rather dark berries, but still easy to distinguish from blackberries. The purple type is a hybrid of red and black raspberries, which is especially popular in the Americas. As for the yellow berry, it is not really a separate type, but a form of red or black.

But about the origin of raspberries as a certain representative of the flora, scientists still do not have a common version. There are wild shrubs on 5 continents, in addition, they are represented by a huge variety. There are arctic raspberry species native to Alaska, the Aleutian Islands, and northern Asia. For some other species, the homeland is East Asia and the Hawaiian Islands. There are also species "born" in Europe or North America.

The first cultivation of the plant began in Europe about 2 thousand years ago, and trade relations contributed to the rapid spread of "cultivated" raspberries. What pleasantly surprised scientists was the chemical composition of wild and cultivated berries. In terms of the content of phenols and anthocyanins, they are almost identical. This fact refutes the opinion that wild raspberries are healthier.

Today, the richest crops of this sweet berry are harvested in Russia, Serbia, Poland, Chile, Mexico, the USA and some other countries.

Nutritional properties

) Health Benefits

Rich in vitamins, antioxidants and fiber, raspberries offer many health benefits.

The high concentration of ellagic acid and phenolic compounds prevent the growth of cancer cells, and raspberry seed oil acts as sun protection. In addition, raspberries protect against aging and help to lose weight.

The concentration of antioxidants in these berries is almost the highest among other fruits. Compared to tomatoes, raspberries contain almost 10 times more of these beneficial compounds. Studies have shown that the phytonutrients found in berries play an important role in reducing the level of oxidative stress, reducing inflammation and the proliferation of cancer cells.

Benefits for blood vessels and heart

Potassium, which is part of the fruit, regulates the heartbeat and blood pressure. The berries contain a lot of manganese, copper and iron - minerals necessary for the production of erythrocytes (red blood cells), and vitamin C helps to restore and strengthen various tissues, including blood vessels.

Recently, American researchers have stated that thanks to flavonoids (anthocyanins), raspberries reduce the risk of heart disease. Polyphenols prevent the accumulation of platelets and regulate blood pressure. Researchers at Harvard University followed 9,000 women aged 25 to 42 for 18 years. It turned out that women who regularly consumed berries were 32% less at risk of a heart attack.

Protection against Cancer and Infection

As mentioned, raspberries are excellent antioxidants containing ellagic acid. It protects the body from the influence of free radicals, thereby preventing the degeneration of cells. Anthocyanins, which give the berries a beautiful bright color, also have antimicrobial and protective properties. Under their influence, the reproduction and growth of some dangerous bacteria and fungi, including vaginal and causing intestinal irritation, slows down. Laboratory studies have proven the properties of raspberries to inhibit the growth of cancer cells in different parts of the body.

Influence on fertility function

Vitamin C and magnesium, working in a complex, improve the fertility of male and female organisms. One theory claims that the antioxidants found in raspberries have a beneficial effect on sperm quality and also reduce the risk of miscarriage.

For lactating mothers, raspberries are useful for enhancing lactation.

Eating berries can help prevent damage to brain cells and memory loss caused by ageing. Studies have shown that frequent consumption of flavonoid-rich berries supports cognitive functions in the brain. Another discovery of scientists: anthocyanins in combination with quercetin prevent age-related memory loss.

Anti-inflammatory effect

Raspberry, which has anti-inflammatory properties, prevents damage to cell membranes. The result of such exposure is protection for the heart, strengthening the immune system and healthy digestion. Recent studies have shown that ellagic acid prevents inflammation in the gastrointestinal tract. Berries have also been shown to be effective in relieving the symptoms of arthritis and gout. It is believed that raspberries have a similar effect on the body as the medications aspirin and ibuprofen.

Strengthens the immune system

Raspberries are rich in vitamin C, which strengthens the immune system, increases the body's resistance to diseases and daily exposure to microbes. The antioxidant properties of ascorbic acid help cleanse blood cells, thereby protecting against invading viruses.
