In addition to organic acids, vitamins, minerals and trace elements, the berry contains anthocyanins. These substances are responsible not only for the color of the raspberry. They protect genes from damage and have anti-inflammatory effects. Anthocyanins help to strengthen the cell membrane, normalize the metabolic processes occurring in them. These natural colors act as powerful antioxidants and also accelerate the breakdown of fats and carbohydrates in the intestines.
In addition, anthocyanins exhibit some antimicrobial properties that rapidly reduce the overgrowth of certain bacteria and fungi in the body, which often lead to various vaginal infections and sometimes even lead to irritable bowel syndrome (IBS) [1].
There are two types of flavonoids present in raspberries - catechins and epicatechins. They are involved in the formation of neurons and new blood vessels, help to strengthen the venous and arterial walls. Flavonoids are essential for normal brain function. They have been proven to prevent the development of Alzheimer's disease [2].
Not only berries, but also raspberry leaves are useful for humans. They have pronounced antibacterial properties.
9 health benefits of raspberries
Raspberries are not only tasty, but also a very healthy berry. By eating it, you can significantly improve your health:
-
Prevention of heart and vascular diseases. Anthocyanins contained in the berry can reduce the intensity of inflammation in the vessels, if any, which reduces the risk of developing heart disease [3].
Scientists have proven that raspberries are better than other foods in helping to increase the concentration of nitric oxide (NO) in the body. This substance allows you to expand the lumen of blood vessels and improve blood flow through them. Therefore, berries must be included in the diet for people who suffer from pathological narrowing of peripheral collaterals. A study of these properties of raspberries was carried out at the College of Public Health, Xinyjiang Medical University, Urumqi, China [4].
- Antioxidant activity. Research from the University of Toronto School of Medicine suggests that raspberries have antioxidant potential that can be beneficial for many health problems [5].
-
Cancer prevention. The compounds contained in berries prevent the formation of tumors in the body. They destroy free radicals that damage healthy cells and contribute to their malignant transformation.
American scientists from the Cancer Research Institute have found that raspberries contain ellagic acid [6]. Ellagic acid is a phytonutrient component of raspberries with key nutrients like kaempferol, quercetin and cyanidin-based molecules called cyanidin-3-rutinoside and cyanidin-3-glucoside-rutinoside. It can reduce the risk of developing cancers of the bladder, lungs, breast, esophagus and skin. Once in the body, ellagic acid molecules deactivate carcinogens. Raspberries should be included in the diet for people who have already been diagnosed with cancer. It has been proven that ellagic acid slows down the rate of spread of metastases throughout the body [7].
Yellow raspberries are not considered as healthy as red berries. At that time, a variety like black raspberry contains the most vitamins. This variety was bred in America, but such a berry is rare. The so-called "crimson trees" are an innovation of recent years. Scientists have created shrubs that do not need supports or garters. They have tough stems on which large berries grow.
American researchers have found that black raspberries are beneficial for people with oral cancer. It contains substances that destroy tumor cells [8].
-
Diabetes Benefits A study was conducted at the University of Michigan aimed at studying the effect of raspberries on the body of people with diabetes. Scientists managed to find out that the phytonutrients contained in it interact with some inactive hormones. This can help control blood insulin levels and improve the well-being of type 2 diabetes and obesity patients.
In 2019, another study was conducted, which concluded that raspberries may reduce postprandial hyperglycemia and have certain anti-inflammatory effects in adults with diabetes [9].
The berry is a valuable food for diabetics, as it contains a lot of fiber. The low glycemic index of raspberries allows you to safely eat them, regardless of blood sugar levels.
-
Anti-inflammatory properties of red raspberries. They use red raspberries to prevent diseases such as:
- Alzheimer's disease.
- Diabetes.
- Obesity.
- Cardiovascular pathology.
The benefits of berries have been proven by numerous studies. It contains a unique combination of ellagitannins and anthocyanins. Their entry into the body prevents the development of chronic diseases.
Recent scientific work suggests that ellagic acid from raspberries can help reduce inflammation in the intestines. The berry is useful for the prevention of gout and arthritis [10]. There is evidence that the substances contained in raspberries have the same effect on the body as drugs (Aspirin and Ibuprofen).
-
Preservation of vision. Raspberries contain carotenoids, zeaxanthin and lutein. These substances help prevent the development of macular degeneration (a dangerous disease that leads to blindness in the elderly).
Just 3 servings of raspberries a day can be a great natural remedy for macular degeneration. Macular degeneration is an age-related disease that affects your vision “in the midpoint” due to retinal damage [11].
- Strengthening immunity. The combination of antioxidants and vitamin C in raspberries is useful for immunity. Plant fiber has a positive effect on the body's defenses. It normalizes bowel function and improves its microflora. This helps to strengthen the immune system, which largely depends on the functioning of the digestive system.
- Improves memory. Raspberry protects brain cells from age-related damage. Thanks to the berry, you can maintain clarity of thought until a ripe old age. This effect is provided by the flavonoids that are included in its composition. Scientists have shown that they have a beneficial effect on all cognitive abilities.
- Eases joint pain. Anthocyanins and polyphenols from berries stop the destruction of joint tissues in people with arthritis. This allows you to stop the progression of the pathological process and reduce the intensity of pain.
Benefits for women

Weight loss. It is impossible to gain extra pounds by eating raspberries. The berry is high in fiber and low in fat. It allows you to stay full for a long time.
Raspberries should be eaten by athletes. The berry has been proven to cover 95% of fluid loss during intense training. Manganese, calcium, phosphorus and potassium help to restore the disturbed electrolyte balance. Therefore, the berry can be eaten both during training and after its completion.
Raspberry ketones (Rheosmin) have fat burning properties [12]. Moreover, they affect those lipid deposits that are difficult to eliminate (fat in the abdomen). Ketones absorb excess fat cells, so weight goes away quickly and without harm to health. All these facts have been proven in the course of numerous studies [13].
Benefits for men
Experts claim that raspberries can improve fertility in both men and women by increasing vitamin C and magnesium levels.
Additionally, in a 2012 study, researchers at the Lawrence Berkeley National Laboratory of the US Department of Energy found a strong correlation between high vitamin C intake and improved sperm DNA quality. An analysis of 80 male volunteers showed that those who consumed the most vitamin C had 20 percent less sperm DNA damage than those who consumed the least. In older men, this nutrient seemed to "turn back the clock" [14].
Consuming more micronutrients such as vitamin C, E, folate, and zinc seems to help older men have the same sperm quality as younger men.

Store them in containers with a tightly closed lid. There should be no products nearby that have a pronounced smell.

Fermented raspberry leaf tea is a beverage that contains many organic compounds. It is made from fresh leaves. Fermentation involves the natural fermentation of a product.
For fermentation, picking raspberry leaves can begin in late spring and continue until early fall. May tea turns out to be especially aromatic and fragrant, and the drink from late leaves is distinguished by its strength and rich taste.

Then the temperature in the oven is reduced to 50 ° C and the raw materials are brought to readiness. Drying in the fresh air is the end. For this, the leaves are left alone for a day.
When the collected raw materials are too coarse, then after withering, you need to put the leaves in a bag and put them in the freezer for 24 hours. Thanks to this treatment, they will become softer, so it will not be difficult to twist them.
