Ripe, juicy grapes have a home in many healthy eaters' crisper year-round. In fact, they're the third most popular fruit in the U.S. (And, of course, they're the key ingredient for making wine.) But despite being enjoyed in a variety of ways, the jury is still out for most folks when it comes to their dried-out form, aka raisins.

So, what are the benefits of raisins, anyway? But, more importantly, is there a downside to eating raisins to keep in mind? Although most dried fruit tends to err more on the higher-in-sugar end of the spectrum, raisins are still considered pretty great for you, according to registered dietitian Jessica Bippen, RD, who breaks down the benefits of raisins and much more ahead.

The nutrient run-down of raisins

Raisins are typically made by drying out grapes in the sun and then processing them in a plant. And while they certainly look very different from grapes, Bippen says raisins are nutritionally very similar to their hydrated counterparts. "The funny thing about raisins is that many people don't realize they have the same benefits of grapes," Bippen says. "They're the same fruit, just dehydrated."

She explains that the major difference is that obviously grapes have much more water than grapes. "Without the water content, the nutrients become much more concentrated," Bippen says. "It also means the sugar becomes more concentrated, so it's important to be aware of that as well." BTW, this is true of all grapes; some manufacturers add extra sugar to grapes, which makes their sugar content higher. And serves as yet another reminder to always read your nutrition labels whenever possible.

With that in mind, here's a brief run-down of raisin nutrition facts found in one small box of raisins (approximately 43 grams):

  • Calories: 129 kcal
  • Protein: 1.42 grams
  • Fiber: 2 grams
  • Fat: 0.1 grams
  • Carbohydrates: 34 grams
  • Sugar: 28 grams
  • Calcium: 27 milligrams
  • Iron: 0.8 milligrams
  • Magnesium: 16 milligrams
  • Potassium: 320 milligrams
  • Sodium: 11 milligrams

What are the benefits of raisins?

1. They're full of antioxidants

"Just like grapes, raisins are a good source of antioxidants," Bippen says. "This is because they are high in a specific type of antioxidants called polyphenols." She explains that polyphenols help fight free radicals in the body, reducing inflammation—making them one of the biggest benefits of raisins. She adds that they are also great for brain health1, connected to boosting cognitive function and protecting against cognitive diseases, such as Alzheimer's and dementia.

2. Raisins contain iron, which benefits cardiovascular health

Bippen also places a gold star next to the high raisin iron content. "This is a nutrient that especially many people who follow a vegan or plant-based diet may not get enough of, so snacking on raisins could especially help them get more of this nutrient," she says. What's even better news is that raisins and heart health essentially go hand in hand. Iron helps with blood flow, she says, which directly benefits the cardiovascular system. For this reason, raisins are a great ingredient to incorporate into a pre-workout snack. "For iron to be absorbed well, it should be paired with vitamin C. Raisins actually have that nutrient as well, so you're getting both in the same source," she says.

Regardless of what eating plan you follow, a good goal is to aim to get 18 milligrams of iron each day—so while raisins aren't the end-all, be-all source of the mineral, incorporating them into your diet can help you meet your needs.

3. They have calcium, which benefits bone health

Raisins also contain small amounts of calcium, which Bippen says can support bone health. (You want to aim to get between 1,000 milligrams and 1,200 milligrams of calcium a day.) Besides being good for your bones—including your teeth—Bippen adds that calcium plays an important role in muscle function, helping assist in relaying messages from the brain to the muscles. Yet another reason why they're good to stash in your gym bag!

4. Raisins have small amounts of protein

While they aren't exactly a powerhouse source of protein like meat, nuts, beans, or tofu are, Bippen points out that raisins do contain the nutrient, and hey, every little bit counts. "This is also helpful in keeping the sugar in raisins from spiking blood sugar as much as it would otherwise," she says.

5. Raisins are a good source of fiber

Just one ounce of raisins contains one gram of fiber, which is pretty impressive for a relatively small amount. (You want to aim to get between 25 grams and 28 grams a day.) "I wouldn't use raisins as your primary fiber source, but it is a great bonus and definitely is beneficial that it is included," Bippen says. Like protein, the fiber also helps keep blood sugar levels at bay that the abundant natural sugars in dried fruits may impact.

Fiber is one of the most important nutrients for the body, helping to lower inflammation as well as boosting gut health. While a handful of raisins is only a small portion of the amount of fiber needed for the entire day, adding it to your oatmeal or salad will get you that much closer to your fiber goals, and benefit your body in the process. And, of course, there are tons of other high fiber foods you can also add into the mix.

Are there any concerns about eating too many raisins?

As mentioned, raisins contain a concentrated amount of sugar per serving, which is why Bippen typically recommends enjoying them in moderation. (Even eating too much fruit at once isn't always the solution.) So, how many raisins to eat per day? "A good serving size would be a handful," she says. She also recommends pairing raisins with other healthy foods, such as nuts or on a slice of peanut butter toast. "The protein and healthy fats in nuts helps keep blood sugar levels steady," she says. "It also makes it a more satiating snack."

Bippen says it's important to keep in mind that some brands add extra sugar to their raisins to make them taste sweeter. "Ideally, the only ingredient listed will be the raisins themselves and possibly sulfur dioxide, which is used for preservation," she says.

In terms of other risks or side effects to keep in mind, like any food, some people may have an allergic reaction or intolerance to raisins. It's also worth noting that raisins are one of the fruits with the highest amount of pesticide residue, as tested by the Environmental Working Group. To minimize your exposure to pesticides when eating raisins, opt for organic whenever possible.
