Grapes are important part of human diet. This fruit has high nutritional value and numerous beneficial effects on the human health. Besides in human diet, grapes are used in cosmetic industry and in the medical purposes. Cultivation of grapes started 8000 years ago.
There are more than 8000 grape varieties from about 6000 species. The two main types of grapes in the world are American and European.
American grapes are available in September and October every year although European grapes are available all year. The best-selling grape in America is called the Thompson Seedless. Golden raisins are made from these types of grapes.
It is not a Fruit
Grapes are a kind of berry. They have a leathery covering and a fleshy inside, similar to blueberries.
Benefits of Grapes
Grapes have long been classified as a low glycemic index (GI) food, with GI values ranging between 43-53. In the case of grapes, recent studies have also shown that the low GI value of grapes is a good indicator of this fruit’s blood sugar benefits. Studies have now connected grape intake to better blood sugar balance, better insulin regulation, and increased insulin sensitivity. We suspect that the strong phytonutrient content of grapes plays a key role in providing these blood sugar-related benefits.
Research on antioxidant benefits provided by grapes or grape components includes the following findings. Grapes and grape components can:
- help prevent certain oxygen-related enzymes from becoming overactive. These enzymes include xanthine oxidase and catalase.
- increase our blood levels of glutathione (a critical antioxidant nutrient) and also increase the ratio of reduced-to-oxidized glutathione (one important measure of antioxidant capacity).
- help protect cell membranes from free radical damage.
- lower levels of oxygen reactive molecules in our blood.
- reduce oxidation of fat (lipid peroxidation).
- lower biomarkers of oxidative stress.
Research on grapes, grape components and cancer has focused on three cancer types: breast cancer, colon cancer, and prostate cancer.
In the case of breast cancer, the grape phytonutrients receiving the most research attention have been the catechins, proanthocyanidins, and stilbenes (especially resveratrol).
For colon cancer, more research attention has been focused on grape flavonoids and grape anthocyanins. (This research tendency may mean that dark purple, red, and black grapes could end up being better choices for colon cancer prevention than green grapes, even though the jury is still out in this area.) One interesting development in the research on grapes and colon cancer prevention has involved studies on GADF, or grape antioxidant dietary fiber.
Antioxidants are also needed, and grapes come through strong in the antioxidant category. This antioxidant-plus-fiber combination may be one of the reasons that colon cancer prevention has jumped out in health research on grapes.
In the area of prostate cancer, it is the stilbenes (including resveratrol) have been the major focus in research on the anti-cancer properties of grapes.
There has been evidence for years that drinking red wine is good for the heart. Scientists claim that a chemical in the skin of red grapes, called resveratrol, will help you live longer. This secret of long life is hidden in skin of grapes in high quantity but it is also found in seeds and flesh of grapes as well. It is proved that Resveratrol activates a group of genes that are directly linked to longevity.
Apart from longevity, grapes help us to control the calorie level of our body. It maintains the calorie level while assuring that our body receives the perfect nutrition and nourishment. It has been proved by researches that maintaining the perfect calorie level can increases lifespan up to 40% over the average lifespan.
Have one cup of 32 red or green grapes everyday to maintain your calorie level and a healthy long lifestyle too.Studies have also suggested that grapes are effective against heart attacks, asthma, migraines, indigestion, kidney disease and fatigue.
Grapes into your diet
- Slice grapes in half and add them to your chicken salad.
- Make your own fruit cocktail with fresh fruit and include grapes, pineapple, sliced peaches and strawberries. Sprinkle a small amount of honey on top of the fruit mixture for an extra sweet treat.
- Freeze grapes and eat them as a snack or dessert on a hot day.
- Have a quick 100-calorie snack with 1 cup of fresh grapes.
Grapes are extremely good for your health; they can help to cure problems such as Alzheimer’s disease, asthma, constipation, heart diseases, indigestion, kidney diseases and migraine. Eating grapes will also minimize the risk of having a heart attack.Link to original
