Grape juice is a sweet beverage made from pressed grapes. It contains compounds that could help support your health and wellness.
Grape juice contains anthocyanins, which are polyphenol plant compounds that give purple and red grapes their color. They may help support heart health by affecting how your blood vessels function.
Studies show that drinking grape juice can improve blood flow through your arteries. The polyphenols in grape juice may also help protect your cells from damage and reduce inflammation. This matters because chronic inflammation can harm your arteries over time and increase your risk of heart disease.
Grape juice might help improve your physical performance during workouts. Research found that runners who drank purple grape juice could run longer before getting tired. It also raised their blood antioxidant levels.
Intense exercise creates oxidative stress in your body, in which highly reactive free radical molecules can damage cells and tire muscles. Antioxidants neutralize these harmful molecules, thereby reducing inflammation.
This protection helps your muscles better handle physical strain, so you can keep going. Plus, the natural carbohydrates provide quick energy to fuel your workout.
Your immune system needs vitamin C to support the production and function of white blood cells that fight infections. Fortified grape juice is a great source, packing about 63 milligrams per cup. That gets you close to the daily goal of 75 mg for women and 90 mg for men.
The polyphenols in grapes also help balance your immune response. They reduce chronic inflammation, which can otherwise confuse your immune cells. This helps your body react quickly to threats without overreacting.
Research suggests compounds in grapes may boost specific defense cells. It supports macrophages that clear germs and rapid-response T cells that spot signs of infection. Since these compounds also aid gut health, they strengthen the immune defenses located in your digestive tract.
Your digestive system contains trillions of bacteria that help you digest food and absorb nutrients. Together, they make up your gut microbiome. The polyphenols in grapes may help increase the variety of these beneficial gut bacteria. A diverse gut microbiome is linked to better digestion, stronger immune function, and improved nutrient absorption.
The plant compounds in grape juice feed the helpful bacteria in your gut. By supporting these microorganisms, grape juice may help maintain the balance your digestive system needs to function properly.
Look for 100% grape juice without added sugars to get the most grape juice benefits. Read the labels carefully, as many fruit juice products contain added sugars and little actual juice.
If you can, choose organic grape juice. Research shows that these crops often contain lower levels of pesticide residues and harmful heavy metals. Organic options may also provide more antioxidants, including higher amounts of vitamin C.
Remember that juice lacks the fiber found in whole grapes. Guidelines recommend you make at least half of your daily fruit intake from whole fruit.
