Black raspberries to treat skin allergies?

Eating black raspberries appears to reduce inflammation associated with skin allergies. This could be a natural way to treat contact hypersensitivity.

A Ohio State University study found that black raspberries can reduce inflammation associated with skin allergies. The results were published in the English-language journal "Nutrients".

Black raspberries to treat cancer?

Ohio State University researchers have been studying the effects of black raspberries on inflammation for years. A diet rich in black raspberries has already shown promise in reducing inflammation associated with some types of cancer. The research group therefore wanted to find out whether the fruit could also reduce inflammation in other diseases.

Black raspberries for contact allergies

A diet high in black raspberries actually appears to reduce inflammation from contact allergies. Contact allergies cause redness and inflammation of the skin. The protective effect of black raspberries was determined in a study in mice. Treatments for the disease are usually applied directly to the skin. Interestingly, just eating black raspberries could have the same effect, the researchers report.

Examination included two groups of mice

The research group fed a group of mice with a diet containing black raspberries. The amount of raspberries consumed in humans corresponded to a single serving per day. There was also a control group in which the mice received the same form of nutrition, but without black raspberries.

Three weeks after the start of the change in diet, the researchers exposed one of the ears of each mouse to special irritants, which caused contact hypersensitivity. Then they measured the decrease in swelling and compared the ears of each mouse. It was found that the swelling in the mice that consumed raspberries decreased more quickly than in the animals that did not eat raspberries.

What did the black raspberries do?

The research group found that the black raspberries apparently modulate so-called dendritic cells, which act as messengers for the body's immune system. These cells signal to the immune system whether it should intervene. In other words, dendritic cells modulate whether inflammation is triggered or not.

Type of body response is very important

The immune system is very complex. By identifying unique cells that are affected by the berries, it is possible to identify how the berries inhibit inflammation, the researchers report. "Many of the bad effects we see are not always due to the pathogens or allergens themselves, but to the way our bodies respond to these triggers," said study author Professor Steve Oghumu of Ohio State University in a press release .

Black raspberries control the body's response

In the case of contact hypersensitivity, for example, a person's skin encounters an allergen to which the body then reacts by flooding the area with cells, which then cause inflammation and itching. "So one way to deal with this type of disease is to control this response, and that's one of the things black raspberries appear to be able to do," adds Professor Oghumu. (as)
