These results suggest a clear relationship between consumption of even modest serving sizes of Concord grape juice, flavonoid intake, and effects on risk factors for cardiovascular disease. This approach to dose-response relationships may prove useful for testing other individual foods and beverages.
Eating large quantities of grapes might cause diarrhea. Some people have allergic reactions to grapes and grape products. Some other side effects might include cough, dry mouth, and headache.
Ultimately, while Concord grapes can be a nutritious addition to one's diet, consumers should be aware of the potential risks associated with pesticide residues on non-organic grapes.
Grapes are high in tannins, which can cause nausea and diarrhea when consumed in excess. Consuming conventional grapes without thorough cleaning can lead to exposure to pesticides, which is a good reason to limit intake.
In more severe cases, grape poisoning can cause respiratory failure, cardiac arrest, and even death. Its essential to seek medical attention immediately if you suspect youve ingested toxic grapes.
Twenty years after the first cases of kidney injury from grape and raisin ingestions were described, the study has identified the likely toxic component. The concentration of tartaric acid in grapes varies from 0.35% to 2%, which makes predicting toxicity difficult.
