A certain cranberry product is a big hit to feed a large number of overseas purchasing agents, this product claims to be able to treat urinary tract infections, vaginitis, pelvic inflammatory disease, uterine fibroids, ovarian cysts, is simply a gynecological holy product, all-encompassing treatment. In the gynecological clinic, I often encounter such patients - doctor, I have been eating cranberry health products, why do I still get gynecological diseases? Today we will take a steak, whether cranberries have a magical effect.
Cranberries, also known as cranberries and cranberries, are bilberry fruits that grow mainly in the cool areas of the Northern Hemisphere in acidic peat soils, and are known as the three traditional fruits of North America along with Concourt grapes and blueberries. The fruit of the cranberry is an oval berry 2 cm to 5 cm long, and when ripe, the epidermis and pulp are bright red and beautiful, but it is very sour and difficult to eat alone, and it needs to be combined with other foods.
Scientists have studied the composition of cranberries and found that it does contain a lot of biologically active substances, such as proanthocyanidins, flavonols, phenolic acids, anthocyanins, etc., most of which have antioxidant effects, can fight against the lipid peroxidation of unsaturated fatty acids in biofilms, play a role in protecting the structure and function of biofilms, prevent aging, tumors and so on. However, any active ingredient without the dose to talk about efficacy, is not appropriate, cranberry as a food, naturally is a good choice, but want to use it as a universal drug to treat gynecological diseases, not very appropriate.
At present, research on cranberries is mainly focused on the prevention and treatment of urinary infections, and laboratory studies have confirmed that cranberry juice can inhibit urinary tract pathogens from adhering to urinary tract cells. This mediator of anti-adhesion may be fructose, which interferes with the adhesion of type 1 Escherichia coli to urinary celiac cells, and proanthocyanidins, which inhibits the adhesion of Escherichia coli. But at the same time, the researchers also found that although the urine p-hair Escherichia coli strain decreased in women who took cranberry juice, there was no significant difference compared with women who did not take cranberry juice.
Cranberry products do not reduce the incidence of urinary tract infections compared to placebo, water, or other treatments. Moreover, cranberry products have not been shown to be effective even for specific groups of people, such as the elderly, pregnant women, women with frequent urinary tract infections, or children, cancer patients, etc. In 2016 Jama published an article in which the use of 1-year cranberry capsules (each case containing the active ingredient proanthocyanidin 36 mg, two capsules per day) and placebo was compared to placebo, the effects of bacteria and pyogenea in the two groups of patients taking cranberries and placebo were not significantly different, and cranberry capsules did not reduce the proportion of patients with bacteriuria and pus.
So far, it has not been confirmed that taking cranberries can effectively prevent urinary tract infections, usually drink water properly, go to the toilet frequently, do not often urinate, go to the toilet in time before and after sexual life, and the effect of preventing urinary tract infections is much stronger than taking cranberries.
The relationship between cranberries and gynecological-related diseases continued in various databases, and the number of relevant studies was 0. In addition, other "health benefits" of cranberries, such as blood sugar lowering and anti-cancer, have not found sufficient evidence to support it.
Cranberries may be effective ingredients in purple potatoes, grapes, blueberries, kale and other vegetables and fruits are also very rich, which can not be regarded as the unique characteristics of cranberries, purple potatoes, grapes, kale these vegetables and fruits are relatively cheap, higher than cranberries cost-effective. In addition, people who have eaten cranberries know that fresh cranberries are too sour, and generally have to be made into drinks and jams with sugar, which will bring additional sugar intake. Long-term use of cranberry juice increases calorie and glucose intake, and some studies have shown an increased likelihood that cranberry juice can cause gastrointestinal side effects such as heartburn.
Cranberries in China most of the rely on imports, the price is high, if you like this sour taste, as a fruit, snack, make jam, biscuits, daily eating is no problem, but to rely on eating cranberries or cranberry health products to treat diseases or prevent diseases, that is not OK, the money spent on this is not worth it, regular gynecological examination is the most important.
