Which Grape Juice Is The Healthiest

Grape juice has been associated with several health benefits. For example, it may promote the health of your heart, immune system, and digestive tract.

Enhances heart health

Thanks to its content of antioxidant compounds, several studies have found that grape juice could support heart health.

According to one review, the flavonoids found in Concord grape juice could help lower several risk factors for heart disease, including (7):

  • inflammation
  • plaque build-up in the arteries
  • platelet aggregation
  • cholesterol and triglyceride levels

In a small study with 25 women, drinking white grape juice daily for 30 days increased levels of HDL (good) cholesterol by 16% and decreased belly fat (8).

Similarly, a review reported that grape products, including grape juice, could significantly improve levels of total, LDL (bad), and HDL (good) cholesterol compared with a control. As such, it might help protect against heart disease (9).

Still, more high quality research is needed to better understand the juice’s effects on heart health.

Promotes immune function

Many varieties of grape juice are enriched with the micronutrient vitamin C.

Vitamin C can enhance immune function by reducing oxidative stress and supporting the function of your immune cells (10).

Getting enough vitamin C in your daily diet may reduce your susceptibility to illness and infection, including respiratory infections, like the common cold (10, 11).

Grape juice is also a great source of antioxidants, like resveratrol, a compound that can reduce inflammation and regulate immune cells (12).

Supports digestive health

Some research has found that grape juice might support the health of your digestive system.

For instance, a recent study showed that taking a grape powder supplement — equivalent to about 3.4 ounces (100 mL) of grape juice — could increase the diversity of your beneficial gut microbiome to promote digestive health (13, 14).

Several studies in animals have found similar results, noting that certain compounds and polyphenols extracted from grapes and grape juice could support the health of the gut microbiome (15, 16).

Some types of grape juice also contain a small amount of fiber, with around 0.5 grams per cup (237 mL) (3).

Although this is much less than the amount found in whole grapes, it can help you meet your daily needs for fiber, an essential nutrient that promotes regularity and digestive health (17, 18).

Summary

Some studies show that grape juice and its components could improve heart health, promote immune function, and support digestive health.
