Grapes are rich in various nutrients, primarily including antioxidant substances, vitamins, minerals, dietary fiber, and natural sugars. Consuming them in moderation can contribute to cardiovascular health, delay aging, improve digestive function, and more.

1. Antioxidant substances

Grapes contain potent antioxidants such as resveratrol and anthocyanins, which can neutralize free radicals in the body and reduce oxidative stress-induced cell damage. These substances have potential protective effects, especially against atherosclerosis and certain cancers. The antioxidant activity of purple grapes is significantly higher than that of green grapes.

2. Vitamin

Grapes are a good source of vitamin C and vitamin K. Vitamin C is involved in collagen synthesis and enhances immunity, while vitamin K is crucial for blood clotting and bone health. Every 100 grams of grapes can provide about 10% of the daily vitamin C requirement.

3. Minerals

Grapes contain various minerals such as potassium, calcium, and magnesium, among which potassium helps regulate blood pressure balance. A deficiency of potassium may lead to muscle spasms and arrhythmias, while consuming grapes in moderation can help maintain electrolyte balance.

4. Dietary fiber

Grape skins and seeds contain insoluble dietary fiber, which can promote intestinal peristalsis and prevent constipation. Eating them with the skins and seeds is more effective, but people with weak digestive function should be aware that it may cause abdominal distension.

5. Natural sugar content

The fructose and glucose in grapes can quickly replenish energy, making them suitable for consumption after exercise. However, individuals with diabetes need to control their intake, and it is recommended to consume no more than 15 grapes at a time, while monitoring blood sugar changes.
