Raisins are famous for being sweet little additions to bran cereal, oatmeal and trail mix. That said, they don’t always have the best reputation, being painted as super-sugary pieces of fruit. Like other dried fruits, raisins contain sugar, which is often natural (not added) sugar. Raisins also offer other nutritional benefits such as vitamins, minerals and antioxidants. Here’s why raisins can fit within a healthy diet.
What Are Raisins?
Raisins are dried grapes. In the United States (mainly in California), Thompson grapes are the most common variety used to make raisins. After harvesting, mature grapes are placed in the sun to dry, according to Britannica. The dehydration process turns the green grapes to a dark brown color and concentrates all of the natural sugars within. Alternatively, grapes can be dehydrated through a more controlled indoor process which involves being treated with lye and sulfur dioxide. This keeps the grape skins from turning brown as they dry, keeping them bright yellow, hence why they are often referred to as golden raisins or sultana raisins.
Raisins are a historically significant food. According to Britannica, references to them can be found in the Bible and Greek and Roman literature. They also play a significant role in cuisines worldwide, including dishes that hail from Iran, Iraq, Turkey and Spain.

Health Benefits of Raisins
Provide Gut-Healthy Fiber
There’s a reason cereal and oatmeal makers add raisins to their products. That added natural sweetness boost and an array of nutritional properties make them a great choice. Raisins offer 2 grams of fiber per ¼-cup serving. Consuming adequate fiber supports both your gut and heart health. Raisins can be a helpful way to reach the daily requirement of 28 to 34 grams of total fiber each day recommended in the 2020-2025 Dietary Guidelines for Americans.
Boost Your Potassium Intake
Raisins are also a great way to get more potassium into your diet. According to the National Institutes of Health, potassium is an important electrolyte involved with muscle contraction, heartbeat regulation and fluid balance within your body.
Help Meet Your Daily Fruit Requirement
Raisins can also be a great way to help you meet your daily fruit requirement, especially if fresh fruit isn’t available, says Maggie Moon, M.S., RD, a Los Angeles-based nutrition expert and author of The MIND Diet. There’s also evidence that raisins may benefit health in other ways. “Research suggests snacking on raisins helps with long-term blood sugar control and may even lower blood pressure,” Moon says. In addition, people who eat raisins tend to have healthier diets: raisins contain antioxidants that may help bolster cardiovascular function, have antibacterial properties that can improve oral health, and are prebiotics, which can promote gut health, per a 2020 review in Nutrients.

Potential Risks
Too much of anything isn’t good. The same is true for raisins. Luckily you’d have to consume a large amount before you’d run into trouble. Moon confirms that It’s hard to over-consume natural foods to the point of a meaningfully negative outcome. She notes that, most likely, the worst thing to happen would be some stomach upset, possibly due to excessive fiber, potassium or sugars. Stick with the recommended ¼-cup serving, and you should be fine. And if you have diabetes, consult your physician and registered dietitian for their recommendations, since even a small amount of raisins can be high in carbohydrates. The American Diabetes Association recommends being cautious of portion sizes when you consume dried fruit.
How to Eat Raisins
Raisins can be enjoyed in several ways. A small handful can be tossed in your morning bowl of cereal or oatmeal. Or you can combine them with nuts, seeds and popcorn to create a homemade trail mix. Be sure to purchase raisins labeled “unsweetened” to avoid any added sugars.
Moon enjoys raisins in warm couscous or rice pilaf dishes to add a bit of contrasting sweetness to the dish. She also recommends trying raisins as a substitution for dried cranberries.

How to Make Your Own
If you’re up for it, you can absolutely make your own raisins at home. Buy fresh grapes and avoid any that look old, have mushy spots or show evidence of mold. Wash and dry the grapes thoroughly, and remove any stems. Spread them out on a large baking sheet lined with parchment paper, and bake at 225°F, until browned and dry, for 4 to 6 hours. Let cool before transferring to a jar and sealing. Store in the refrigerator for best results.
The Bottom Line
Raisins are a delicious way to add flavor and nutrition to your meals and snacks. They are rich in fiber that helps support your gut and heart health. Just keep an eye on the portion size and choose varieties labeled “unsweetened” or with “no added sugar.”
