10+ Reasons Why Eating Grapes Is Good for You

Eating grapes is pretty easy. It’s so easy, in fact, that you might not really appreciate how much grapes do for your health after you gobble them down.

This naturally sweet fruit is rich in nutrients that can protect your body in more ways than you may realize. Let’s look at a whole bunch of benefits with registered dietitian Anthony DiMarino, RD, LD.

Health benefits of grapes

Don’t let the small size of grapes fool you: There are a lot of positives packed into that ready-to-eat package. A 1 cup (151 grams) serving of grapes delivers a healthy serving of many key nutrients, like:

• Vitamin C
• Vitamin K
• Potassium
• Copper
• Thiamin (Vitamin B1)
• Riboflavin (Vitamin B2)

Grapes are high in water content to help keep you hydrated, too. They also have enough natural sugars to satisfy a sweet craving without raiding the snack machine.

And did we mention that a serving of grapes is only 104 calories?

“Grapes are loaded with nutrients that support your overall wellness, all while being refreshing and convenient,” says DiMarino. “They’re a great example of a food that makes healthy eating feel easy.”

Adding grapes to your eating routine may also offer these benefits:

Strengthened immune system

Grapes are a fabulous source of vitamin C, which is known for its ability to boost your immune system to help keep you from getting sick. “If we have a strong immune system, our body’s better able to fight against and prevent any sudden, short-term illness,” says DiMarino.

So, maybe popping a few grapes a day will keep the doctor away. (Move over, apples!)

Guard against cancer

Grapes are full of antioxidants — like resveratrol and catechins — that fight free radicals in your body. Free radicals are mayhem-causing molecules that can damage cells. When that damage builds up, it can lead to mutations that increase cancer risk.

“Antioxidants help keep free radicals in check, which can limit oxidative stress and inflammation to reduce the risk of cancer and chronic illness,” notes DiMarino.

Lower blood pressure

The potassium in grapes can help lower your blood pressure by working to balance sodium levels in your body. In addition, those helpful antioxidants we mentioned also support blood vessel function.

Put it all together, says DiMarino, and you have a fruit that helps your circulatory system work more efficiently.

Heart protection

Your heart will absolutely love grapes! That’s because antioxidants like those found in grapes have been shown to limit heart disease risk, emphasizes DiMarino. In addition, the potassium in grapes qualifies as heart-healthy, given its ability to lower your BP.

Reduced cholesterol

Grapes have a fiber-rich exterior skin. Eating a diet high in fiber can help clear artery-blocking “bad” LDL cholesterol from your system. Research shows that adding grapes to your diet can be beneficial for lowering LDL and total cholesterol.

“I always explain it almost like a street sweeper,” illustrates DiMarino. “That fiber gets in your bloodstream and carries cholesterol into the liver, where it gets processed and removed.”

Blood sugar management

Grapes have a low glycemic index number, meaning they won’t spike your blood sugar if eaten in moderation. (More on that in a bit.) Studies also show that nutrients (like resveratrol) in grapes may increase insulin sensitivity to help your body use glucose.

Boosted brain health

All the do-good antioxidants in grapes can help protect brain cells by limiting oxidative stress. Some of the chemical compounds found in grapes can also boost blood flow, which your brain needs to be at its best.

Over time, DiMarino says these factors may help support memory and overall brain health while also protecting against dementia and other cognitive disorders.

Strengthened bones

Want to make your inner skeleton grin like a Halloween decoration? Then eat grapes! They’re loaded with bone-supporting nutrients, including vitamin K and minerals, like calcium, magnesium and potassium.

Graceful aging

Eating grapes may help in your battle against Father Time. Resveratrol (yes, that powerful antioxidant again) has been linked to a longer lifespan due to its effects on cells, oxidative stress and inflammation.

“The antioxidant can contribute to healthy aging and longevity,” says DiMarino.

Improved sleep

Having a hard time getting a good night’s sleep? Grapes may help you catch some ZZZs because they contain melatonin, which helps regulate the sleep-wake cycle. They also provide carbohydrates that help you use sleep-related hormones better.

“While grapes aren’t necessarily a sleep remedy, they may be a helpful part of a diet supporting better rest,” says DiMarino.

Are there any concerns about grapes?

While grapes are healthy and nutritious, a few things about the fruit deserve your attention, says DiMarino. The short list includes:

• Sugar content: A 1-cup serving of grapes contains 15 grams of natural sugars. Given how easy it is to gobble down a lot of grapes, it’s important to watch how much you eat to limit blood sugar fluctuations and extra calorie intake that could fuel weight gain.
• Choking risk: A grape is small, round and firm — and if swallowed whole, it can easily block your airway. This is particularly dangerous for children. It’s best to cut grapes lengthwise into smaller pieces before serving to young kiddos.
• Digestive issues: If you overdo it eating grapes, the natural sugars and fiber in grapes may cause gastrointestinal (GI) issues like bloating or gas. Again, practicing portion control — stick to that 1 cup serving — can help you avoid these issues.

What type of grapes are best?

You have options when you shop for grapes. You can go green, red or black, for instance. Or perhaps a variety with a fun name catches your eye.

But is one type of grape healthier than others? Not really, says DiMarino. Basically, they’re all healthy choices. (That being said, red and black grapes may have a slight edge given that they tend to have more antioxidants.)

“What’s most important is eating grapes in their natural form,” adds DiMarino. “So, instead of drinking grape juice or eating raisins, a plain and unprocessed grape is where you’ll get the most nutrition.”
