On Saturday, August 17, 2024, a sweet surprise came to light in the fight against diabetes. While many believe those with diabetes must avoid sugar entirely, new research suggests there’s room for a little sweetness in a healthy diet. The good news? Raisins may be the perfect snack to help manage blood sugar levels.
If you have diabetes, the advice is often to cut out all sugar to maintain healthy glucose levels. But experts are now saying this approach might not be necessary. Allowing yourself a small sweet treat every now and then could actually prevent overeating later. In fact, one sugary snack is showing promise in managing blood sugar levels for diabetics. Believe it or not, that snack is raisins.
Fruit Snacks Are Not What You Think: Here’s Why They Aren’t Really Healthy
Raisins are not usually a go-to snack when thinking of healthy options. Most people overlook them, associating them more with their sugary taste rather than their health benefits.
However, a study published in The Physician and Sportsmedicine Journal sheds light on the potential health benefits of this dried fruit, particularly for those managing type 2 diabetes. Surprisingly, the research found that raisins are a good option for keeping blood sugar levels in check without causing harmful spikes.
The study was conducted by a team of researchers from the Louisville Metabolic and Atherosclerotic Research Center. They recruited 51 participants to examine the effects of raisins on blood sugar levels over 12 weeks. Some of the participants were given dark raisins as their daily snack, while others consumed processed snacks like chips or cookies. The results were remarkable.

The research revealed that participants who snacked on raisins experienced a significant drop in their blood sugar levels. Just one ounce of raisins per day reduced their glucose levels after meals by an impressive 23%.
Even more striking, those who ate raisins saw a 19% reduction in their fasting glucose levels compared to participants who ate processed snacks. These findings suggest that raisins may offer a natural way to manage blood sugar levels, making them a potentially beneficial snack for those with type 2 diabetes.
But the benefits of raisins didn’t stop there. The study also found that participants who ate raisins experienced a reduction in their systolic blood pressure, which is the top number in a blood pressure reading.

Although there was no significant change in diastolic blood pressure (the bottom number), the reduction in systolic pressure is still a positive indicator of better heart health. This aligns with previous studies that have shown raisins can have a positive impact on cardiovascular health.
Interestingly, while participants who consumed raisins didn’t experience major changes in other health markers like body weight, fasting insulin levels, or cholesterol, the researchers still concluded that raisins are a healthier snack alternative to processed foods.
The study authors wrote, “These data support raisins as a healthy alternative compare[d] to processed snacks in patients with [type 2 diabetes mellitus].” It’s clear that while raisins may not be a cure-all, they offer meaningful benefits for those managing diabetes.
So, why exactly are raisins good for diabetics? According to Mary Dragon, a nutrition counselor and owner of The Barn Nutrition and Fitness, it comes down to their glycemic index. The glycemic index (GI) is a measure of how quickly a food raises blood sugar levels after being consumed. Foods with a high GI cause blood sugar levels to spike quickly, while those with a low GI have a slower, more gradual impact.
Raisins have a medium glycemic index of around 66. This means they don’t cause a rapid blood sugar spike like other sugary snacks do. Dragon explains that this may be due to the fact that raisins contain a type of sugar called fructose, which is processed differently by the body than glucose. Unlike glucose, which enters the bloodstream directly, fructose is processed by the liver. This slower absorption of sugar helps prevent the dramatic rise in blood sugar levels often seen with other sweet treats.
But the benefits of raisins go beyond their glycemic index. Dragon also points out that raisins are rich in fiber and antioxidants. Fiber is crucial for people with diabetes because it helps slow digestion and the rate at which sugar enters the bloodstream. This steady release of sugar can help maintain stable blood glucose levels throughout the day.
Antioxidants, on the other hand, play a role in reducing oxidative stress in the body. Oxidative stress occurs when there’s an imbalance between free radicals (harmful molecules) and antioxidants.

Over time, this imbalance can lead to inflammation and insulin resistance, both of which are major contributors to the development of diabetes. By including antioxidant-rich foods like raisins in your diet, you may help protect against insulin resistance and reduce the risk of further complications from diabetes.
Raisins also provide a variety of essential vitamins and minerals. They are a good source of iron, which is important for maintaining healthy blood cells, as well as potassium, which supports heart health and helps regulate blood pressure. Additionally, raisins contain small amounts of calcium, magnesium, and vitamin C, all of which contribute to overall health.
Still, while raisins have many benefits, Dragon emphasizes that moderation is key. A small portion, like a quarter cup added to oatmeal or a handful mixed into a trail mix, is a great way to enjoy the benefits of raisins without consuming too much sugar.
Even though raisins have a lower glycemic impact than other sugary foods, they still contain a significant amount of sugar—about 18.5 grams per ounce. For this reason, Dragon advises that diabetics should consume raisins in moderation to avoid overloading with sugar.

If you’re concerned about the sugar content, there are ways to incorporate raisins into your diet without causing a blood sugar spike. One option is to mix them with other foods that have a low glycemic index, such as nuts or seeds. This combination can help slow down the absorption of sugar even further, making it easier to keep your blood sugar levels under control.
Another strategy is to eat a smaller portion of raisins. The study showed that consuming just one ounce of raisins per day was enough to produce significant health benefits. If you’re still worried, try cutting that portion in half and see how your body responds.
You might find that even a small amount of raisins is enough to satisfy your sweet tooth while helping you maintain healthy blood glucose levels.
While it’s important not to deprive yourself of all sugar, finding a balance is crucial. For many diabetics, the idea of enjoying a sweet snack like raisins may seem impossible, but the research is clear.
In moderation, raisins can be a helpful addition to a healthy diet. They provide natural sweetness without the harmful blood sugar spikes associated with other sugary foods.
Raisins offer a surprising range of health benefits for people with diabetes. From lowering blood sugar levels to reducing blood pressure, this simple snack may be an excellent choice for those looking to manage their condition.
As with any food, moderation is important, but the research suggests that raisins can be a healthy alternative to processed snacks and sweets. If you’re living with diabetes and craving something sweet, consider reaching for a small handful of raisins. They just might be the sweet secret to better health.
