Sour cherries lower high blood pressure and cholesterol


Sour cherries improve memory, blood lipid levels and blood pressure

Cherries are a popular summer fruit. Even if the sweet representatives of the cherries are often the more popular snack, there are good reasons to use sour cherries. A recent study showed that eating sour cherries has a surprising effect on eyesight and other aspects of cognitive performance. In addition, the ingredients had a positive effect on LDL cholesterol and systolic blood pressure.

Researchers from the University of Delaware found in a study that regular consumption of sour cherry juice has several positive effects on health. At least that counted for the juice of the Montmorency cherry. Participants not only increased their cognitive performance as a result of their consumption, but their lipid levels and blood pressure also showed improvements. The test subjects showed a decrease in “bad” LDL cholesterol and a lower systolic blood pressure. In a control group who received a placebo drink, the effect failed to materialize. The study results were presented in the journal "Food & Function".

A real "superfood"

Many foods are advertised as "superfood" these days, but only a few of these products stand up to scientific investigation. According to the current study, the Montmorency sour cherry can confidently claim the title "Superfood" because regular consumption has been shown to bring several positive health aspects.

Ingredients

Cherries contain vitamin A, vitamin C and folic acid. In addition, there are the minerals potassium, calcium, phosphorus, magnesium, iron and zinc.
Anthocyanins color the cherries red. This dye works against free radicals and UV rays.

Course of the study

The participants, all between the ages of 65 and 80, drank a glass with 230 milliliters of sour cherry made from Montmorency cherry twice a day. Compared to participants who were served a placebo drink, it was shown that consumption of sour cherry juice was accompanied by cognitive improvements and improved blood values.

Why does sour cherry juice have this effect

The exact reasons why Montmorency cherry juice has this effect have not yet been finally clarified. The researchers suspect that bioactive substances such as polyphenols in the fruit are responsible for the effect. However, the exact background must first be checked in further investigations. The effect must also be tested on a larger number of subjects, since the number of participants was insufficient for a generally valid statement.

A useful addition to the diet

Nevertheless, the results suggest that sour cherry juice in daily diets can help maintain healthy brain function and reduce oxidative stress and inflammation. The researchers therefore see the juice as a useful addition to the diet, especially for older people. (vb)
