Valuable Cranberry antioxidants
Cranberries contain proanthocyanidins of type A. These are particularly valuable, highly effective antioxidants which protect the human organism from damage by free radicals from the food and the environment.
Most other fruits often contain the less effective B-proanthocyanidins.
The recommendation to use cranberry juice for bladder infections is well known. There are, however, very few studies that clearly show the effects of cranberries on bladder infections.
For example, the amounts of cranberry used vary. On the other hand, juice is used in some studies, in other powders and again in other capsules. In addition, many of the test subjects broke off prematurely from participation in the studies – so that one could hardly speak of comparable, let alone, useful results.
Cranberries Prevent Bladder Infections
However, there are studies that show that cranberries prevent regularly recurring cystitis.
Usually, these are treated with antibiotics. This procedure damages the health of the patients in the long run, since nothing is changed at the cause (weakened immune system, little defensive mucous membranes, dysbiosis, etc.), but only the recurring bacteria are combated.
Not infrequently, women are released after the antibiotic therapy their bladder infection, only then to a Scheidenpilzinfektion to suffer – a typical sequence of antibiotics treatments.
Once the vaginal fungus has been struck with anti-fungal agents, the next bladder infection is already in front of the door.
A meta-analysis of different studies by scientists from the Greek University of the Aegean revealed that cranberries can prevent recurring bladder and kidney problems.
The researchers suspect that cranberries prevent disease pathogens from settling on the inner wall of the bladder. At the same time, they should stop inflammatory processes in the body and thus prevent an increase in the disease germs.
Cranberry antioxidants protect the heart
Of course, the anti-inflammatory properties of the cranberries benefit not only from the bladder-kidney tract.
Cardiovascular risk is also likely to reduce cranberries, as the results of a scientific study suggest from Korean nutritionists.
Thus, rats that had mixed cranberry powder for six weeks in their feed had a higher content of “good” HDL cholesterol in the blood and at the same time lower inflammatory values than their conspecifics, although all had received an unhealthy diet for the heart.
“Good” HDL cholesterol is the natural counterpart of “bad” LDL. Increased LDL levels and inflammation levels increase the risk of cardiovascular disease. Accordingly, cranberries could also prevent such diseases.
Overall, therefore, it is clear that cranberries contain large amounts of health promoting substances. Especially antioxidants from cranberries are definitely good for the human organism, since they reduce the risks for numerous diseases.
The results of different studies therefore also show that cranberries – in whatever form and dose – have positive effects, inter alia, on blood pressure, sugar metabolism, stomach health, inflammation values and vascular function, that they can be used in cancer prevention (As demonstrated in an Israeli study in 2004).
Cranberries – as fruit, juice, tablet or powder?
It is still not clear whether cranberries have the best fruit, juice, tablet or powder form. There is still uncertainty as to the dose required.
In a 2006 study, published in the World Journal of Urology, however, it was possible to observe a definite defensive effect on the typical bacteria that cause bladder infections, even after the one-time drinking of 750 ml of cranberry juice for dinner . A therapeutic and preventative effect can be assumed, for example, if 250 ml of cranberry juice are drunk twice a day for several weeks.
A French study from 2010 showed that cranberry powder can protect against bladder infections if it contains 72 mg of proanthocyanidins per daily dose, ie standardized for this proanthocyanidine content.
And a Chinese study from 2005 could achieve significant results in Helicobacter pylori control when the subjects drank 250 ml of cranberry juice twice daily for 90 days. Helicobacter pylori is the bacterium that is responsible for numerous stomach problems up to stomach ulcers and stomach cancer.
