Concord grape health benefits

Grapes come in different colors. The darker color of the grapes, the better nutrients.

Red and dark purple Concord grapes are high in two flavonoids – quercetin and rutin. One study conducted by scientists at the University of Wisconsin, looked at the effects of two servings of Concord grape juice a day in fifteen people with coronary artery disease.

After two weeks, the subjects had improved blood flow and reduced oxidation of LDL cholesterol.

The Concord grape variety is chiefly used for the manufacture of grape juice. Approximately 96% of the juice made in New York state is prepared from Concord Grapes. Natural acidity, color and aroma of fresh grape berries provide quality in single strength Concord grape juice. Acidity above 0.85% results in juice that is too tart.

Hot pressing of the grapes is important to extract anthocyanin pigments, flavor components, amino acids, organic acids, sugars, minerals, tannins, and other ingredients. The only sugars are found in Concord grapes are glucose, fructose and sucrose, and the major nonvolatile acids found were tartaric and malic.

In one study, purple color red Concord grape juice help prevent breast cancer. An experiment was conducted on laboratory rats. There was significant reduction in breast tumor mass after they were fed the grape juice on the experimental basis.
