1. HEART DISEASES
Numerous studies have been conducted focused on the impact of grapes in preventing or slowing down heart diseases.
About 20 years ago, scientists discovered that French people had less heart related health problems than other countries all around the globe. This discovery was called the French Paradox. The main explanation for this was that French people drank red wine with their meals.
Since this discovery was made, more than 300 other studies were carried out, proving that red wine or grapes juice can reduce the risk of heart diseases in time.
It seems that grapes juice or wine block the artery clogging effects of fatty food products.
Coronary heart diseases occur when plaque accumulations build up on the walls of arteries. This can lead to a blockage of vessels supplying blood to the heart (or brain) causing heart attacks (or strokes).
Antioxidants in fresh grapes, known as polyphenols, are responsible for preventing the accumulation of oxidized cholesterol (this was proven in a study that was published in the Journal of Nutrition).
Grapes seem to be very good cancer fighting fruits.
They contain high levels of caffeic acid, a very strong cancer fighting substance.
Bioflavonoids, another nutrient contained by grapes, facilitate the absorption of vitamin C into our bodies and help vitamin C maintain healthy connective tissue in our bodies. They also function as antioxidants, by protecting vitamin C from oxidation and by preventing ruptures in capillaries.
Bioflavonoids provide strength to our cells in the battle with cancerous cells and also help kill cancer cells.
The early mentioned nutrient, resveratrol, also helps in preventing cancer, especially liver, lung, breast and prostate cancer.
As for heart diseases, red grapes are best for cancer prevention.
Health benefits of grapes is a study conducted at Erciyes University in Turkey, scientists discovered that grapes have an effective antimicrobial action. The study revealed that this action applies for certain bacteria, like Stoph and the famous E. coli.
Additionally, the high concentration of tannin, another polyphenol contained by grapes, can help fight viruses and tumors. Tanin is absorbed in the intestinal tract, where it is most effective in fighting viruses.
Although we have found that resveratrol has a lot of health related benefits, the list is not over yet.
As we have previously discussed, resveratrol is a natural antioxidant that can help reduce heart diseases, the risk of cancer and even brain diseases like Alzheimer’s.
Besides these benefits, resveratrol seems to influence genes controlling the aging process.
According to Harvard Medical School researchers, this substance can restrict calories intake. It activates enzymes that slow aging, thus increasing DNA stability and extending life span by 70%.

1. HEART DISEASES
Grapes are small round or oval berries that feature semi-translucent flesh encased by a smooth skin. Some contain edible seeds while others are seedless. Like blueberries, grapes are covered by a protective, whitish bloom. Grapes that are eaten as is or used in a recipe are called table grapes as opposed to wine grapes (used in viniculture) or raisin grapes (used to make dried fruit).
Flavonoids are phytonutrients that give the vibrant purple color to grapes, grape juice and red wine; the stronger the color, the higher the concentration of flavonoids. These flavonoid compounds include quercitin, as well as a second flavonoid-type compound (falling into the chemical category of stilbenes) called resveratrol. Both compounds appear to decrease the risk of heart disease by:
- Reducing platelet clumping and harmful blood clots
- Protecting LDL cholesterol from the free radical damage that initiates LDL’s artery-damaging actions
Grapes and products made from grapes, such as wine and grape juice, may protect the French from their high-fat diets. Diets high in saturated fats like butter and lard, and lifestyle habits like smoking are risk factors for heart disease. Yet, French people with these habits have a lower risk of heart attack than Americans do. One clue that may help explain this “French paradox” is their frequent consumption of grapes and red wines.
The combination of crunchy texture and dry, sweet, tart flavor has made grapes an ever popular between meal snack as well as a refreshing addition to both fruit and vegetable salads. American varieties are available in September and October while European varieties are available year round.
- Asthma: Due to its eminent therapeutic value, grapes can be used for cure of asthma. In addition to it, the assimilatory power of grapes is also higher. It increases the moisture present in lungs.
- Heart diseases: Grapes increase the nitric oxide levels in the blood, which prevents blood clots thereby reducing the chances of heart attacks. In addition the antioxidant present in grapes prevents the oxidation of LDL cholesterol, which blocks the blood vessels.
- Migraine: Ripe grape juice is an important home remedy for curing migraine. It should be taken early in the morning, without mixing additional water.
