Green or red grapes: which one offers more antioxidants?

Darker colored varieties tend to contain a greater quantity and diversity of polyphenols, a group that includes anthocyanins, flavonols and resveratrol. These compounds are studied for their antioxidant action and possible contribution to protecting cells against damage caused by oxidative stress.

Anthocyanins are responsible for the red, purple and bluish tones of the fruit. As green grapes do not have this pigmentation, their concentration of these substances tends to be lower. This gives dark varieties an advantage when the comparison specifically considers the content of antioxidants linked to color.

This does not mean, however, that green grapes have little nutritional value. It also offers polyphenols, including flavanols and flavonols, as well as water, vitamins and minerals. The amount of these components varies depending on the species, cultivation, degree of maturation and storage conditions.

What about resveratrol?

Resveratrol is mainly found in grape skins. Red and purple varieties generally have higher concentrations of the compound than green varieties, although values ??can change a lot depending on the type of fruit and the method of production.

Studies associate grape polyphenols with possible favorable effects on cardiovascular markers, inflammation and blood vessel function. The evidence in humans, however, points to modest benefits and does not allow treating resveratrol or any type of grape as a means of preventing or treating diseases alone.

It is also not appropriate to use red wine as a strategy to increase your resveratrol intake. Although the drink may contain more of this compound than white wine because it remains in contact with the skin during production, alcohol poses health risks. The whole fruit also provides fiber and can be consumed without the effects associated with alcoholic beverages.

Which one to choose?

Those looking for a higher concentration of anthocyanins and a variety of antioxidants can prefer red, purple or black grapes. Still, the best choice is one that favors the regular consumption of fruit within a balanced diet.

Varying colors is also a simple strategy to increase your intake of different plant compounds. In practice, both green and red grapes can be part of a healthy diet, without the need to exclude one of them.
