Some varieties of black grapes are much higher in antioxidants than green or red grapes. These chemical compounds help protect your cells from damage. They protect against diseases like cancer, diabetes, Alzheimer's, Parkinson's, and heart disease.
In general, dark red and purple grapes are higher in antioxidants than green or white grapes. The antioxidants found in grapes can help protect your cells from free radicals, which are a natural byproduct of your body's biological processes.
If you're looking for the healthiest grape, red grapes are the clear winner. The anthocyanin that makes red grapes red is actually a mutation of green grapes, and what makes red healthier than green.
"Although all types of grapes are healthy, red grapes and Concord grapes are higher in flavonoids and phytonutrients, including resveratrol," said Rumsey. Though sometimes available fresh, Concord grapes are usually used to make grape juice, grape jelly and grape flavoring.
Concord and purple grapes have significantly higher total antioxidant activities than red or green grapes which were very similar. The antioxidants in the purple and red grapes were found primarily in the skin, whereas, in the Concord and green grapes, the TAC was equally divided between skin and pulp.
The resveratrol in black grapes provides anti-aging capabilities. The skin is more likely to remain youthful and supple. It helps to prevent the degradation of skin cells so they remain intact and working as intended to keep the skin looking soft and smooth.
In most types of grapes, vitamins, minerals and fiber are roughly the same. If you're concerned about carbohydrates, then green grapes are the best choice because gram for gram, they contain slightly less sugar.

Both red and green grapes contain 15 grams of sugar per cup, which is one gram more than a medium-sized banana, another fruit which is infamously high in sugar. The grapes with the highest sugar content are Cotton Candy Grapes, packing 28 grams of sugar in a one-cup serving.
A bowl of grapes on a daily basis which consists of thirty to forty grapes is acceptable but anything more than that can lead to some unavoidable side effects. Grapes are high in natural sugar and excess consumption of foods with the high sugar content can result in loose stool.

Grapes contain a chemical compound called resveratrol. Studies have shown that resveratrol can help your body metabolize fatty acids, increase your energy level, and improve your overall metabolism, all of which can help with weight loss.
Wondering how many grapes in a day is good for weight loss? Most doctors recommend eating 1.5 to 2 cups of fruits a day, which amounts to 200 to 300 g. So, limit your consumption of grapes to 150 g (1 cup) per day, and add more fruits to your diet to get a wide range of nutrients.
Grapes contain natural sugar, but they're considered a low glycemic index (GI) food. This means a single serving is unlikely to raise your blood sugar significantly.
