Studies that reveal their beneficial effects on health still appear, even some researchers have described them as "the fruit of the 21st century". Studies carried out at the University of Clemson and the United States Department of Agriculture qualify the cranberry as the food of greatest antioxidant power among 40 vegetables analyzed. This antioxidant power is due to the combined action of its organic acids and the 15 anthocyanins that give them their peculiar color (among which stand out the mirtilina, the cyanidin, the definidina, the malvidina, the peonidina and the petunidida). In addition, they contain flavonoids and tannins, and a wide variety of essential minerals such as manganese, vitamin C) and several B vitamins.

Properties and benefits of blueberries If you want to know what are the benefits of cranberry consumption, in the following lines you can find the most important ones. 1. Reduce the risk of suffering cancer Cancer is one of the diseases most feared by humans, and in recent decades the number of cases of individuals with cancer has increased. According to esteem the Spanish Society of Medical Oncology (SEOM), in 2015 220,000 cancer patients were diagnosed in the Spanish territory. Some studies have concluded that the consumption of this fruit can help to fight the risk of proliferation of cancer cells when these are few and, in addition, they do it without damaging other cells. This is because blueberries contain gallic acid and resveratrol, two important compounds that help reduce the negative impact of cancer. 2. It is anti-inflammatory Cranberries contain a lot of antioxidants, one of the most important are proanthocyanidins. It is known that these chemicals are powerful anti-inflammatory agents. In this way they reduce some pathologies, since inflammation is one of the most common causes of diseases such as stiffness or muscle pain, to fibromyalgia. 3. Rejuvenates Proanthocyanidins, present in this food, are also important for the body because they have a great capacity to fight other phenomena and to improve health. In addition, they seem to be useful for reversing the aging process in several ways, including by removing free radicals in the skin and other organs, to make the skin look healthy and young.

Prevents neurodegenerative diseases Cranberries have substances that act as neuroprotective agents, largely due to their massive antioxidant content that has already been discussed in the previous points. Gallic acid plays a very important role in terms of neuronal function, since it prevents cognitive deterioration and the development of certain degenerative diseases such as Alzheimer's and Parkinson's, by preventing the oxidation of cells in the brain, which makes they degenerate more slowly 5. Prevents DNA damage Oxidative damage can occur in our cells on a daily basis, and this oxidation is one of the reasons why humans age. That's why antioxidants are so important. But oxidation can also affect DNA, and in this way mutations can occur, which in turn increase the risk of cancer. Research shows that consuming blueberries daily decreases oxidative DNA damage by up to 20%. 6. Help fight against diabetes A study published in 2010 in the Nutrition Journal states that consuming this fruit improves insulin sensitivity in obese people resistant to this hormone. Therefore, consumption of blueberries can help fight against diabetes. Insulin is a hormone produced in the pancreas, which helps the body metabolize carbohydrates correctly, and prevents blood sugar from increasing excessively.

It favors the presence of good cholesterol According to the United States Department of Agriculture, cranberry is the fruit with the highest amount of antioxidants, and considers it one of the best foods to fight cholesterol. Cranberries increase the hepatic synthesis of good cholesterol or HDL and inhibit the formation of bad cholesterol or LDL. 8. Reduce blood pressure Cranberries help reduce and regulate blood pressure, in large part because they cause a greater flow of antioxidants and nutrients in the body, which prevents the accumulation of cholesterol, and generally this helps the body to function better. Cranberries can also prevent blood glucose spikes by improving the body's response to insulin. This means that the organism transports nutrients better and the blood circulates without problems. Also, a recent study from the University of Florida concludes that daily consumption of blueberries could be key to reducing blood pressure. 9. Improves cognitive functions and memory It has been shown that blueberries increase cognitive function in rats and humans. It has also been shown that cranberries improve memory. For one study, a group was asked to drink cranberry juice daily and a control group should consume a placebo drink. The group that consumed the cranberry juice showed positive increases in the learning of couples and the memory of words. 10. Improve the view The retina of the eyeball can also suffer oxidative damage, as it is a vulnerable tissue and can be easily damaged by inflammation or infections.
