Regular or frequent consumption of grapes can alleviate knee pain associated with osteoarthritis and improve joint flexibility and overall mobility – confirmed a study presented earlier this year at the Experimental Biology conference in San Diego, USA. Additionally, it has been confirmed this year that red grapes can significantly boost the functioning of the immune system. In both cases, the effect is attributed to specific antioxidants that grapes are exceptionally rich in.
Recent research only confirms what has long been known: that grapes are a superfood that should be part of daily meals as often as possible. The grapevine is one of the oldest cultivated plants in the world, having been grown for over 8000 years in the regions of Asia Minor, the Caucasus, Mesopotamia, and Egypt. Green, red, or nearly black juicy clusters were early recognized as a versatile source of nutrients, vitamins, and minerals necessary for the body – whether it is fresh fruit, dried berries that provided energy in winter, or wine.
Healing Properties
The main asset of grapes is their high levels of polyphenols, compounds that protect blood vessels and the heart, and prevent certain types of cancer (esophagus, lungs, mouth, throat, pancreas, and intestines). These are powerful antioxidants that, in addition to the aforementioned, protect against premature aging, prevent platelet aggregation, and reduce blood pressure through anti-inflammatory mechanisms. Furthermore, the high levels of fiber and potassium in grapes have a beneficial effect on the entire cardiovascular system.
Red grapes also contain iron and copper, minerals necessary for the production of red blood cells and the synthesis of hemoglobin, and therefore should be on the menu of anyone suffering from anemia. Grapes normalize the functioning of the intestines and kidneys, and the sugars from grapes quickly enter the bloodstream, making this fruit an excellent source of quick energy during exertion. Black grapes, on the other hand, contain the pigment anthocyanin, from the group of plant phenols, a strong antioxidant similar to lycopene in tomatoes. It is a powerful defense against the destructive effects of free radicals, inhibits blood clotting, lowers bad cholesterol, and reduces the risk of stroke and tumors. Additionally, black grapes, not only in wine but also fresh, can help you sleep better as they increase the level of melatonin, the hormone for good sleep.
Anyone suffering from allergies should reach for grapes, which can reduce symptoms with their anti-inflammatory properties, and recent studies have proven that resveratrol (another of the super antioxidants) in grapes can prevent retinopathy and diabetic neuropathy.
However, grapes are not recommended for everyone due to their high potassium content, especially for those with kidney problems.
Versatile Fruit
There are countless ways to consume grapes. Clearly, the healthiest way is to eat them fresh. Since grapes arrive on our tables from all over the world, it should be noted that they are classified among the top 12 foods that regularly have the highest levels of pesticides. If you are unsure, it is best to wash grapes thoroughly, although (fortunately) the compounds in the grape skin prevent the penetration of toxins into the flesh. Fresh grapes are best stored in the refrigerator.
