Carbs

Raisins have 11 grams of carbs per half-ounce (14g), compared to fresh American-type grapes, which have about 2.5 carbs in a similar serving size of 6 grapes (14.4g). Grapes, depending on the variety, have fewer calories than raisins, but also less fiber. The carb, calorie, and fiber counts in golden raisins are similar to dark raisins. Raisins with seeds provide more fiber, with similar amounts of carbs and calories.

While raisins are high in carbohydrates, their sugar is mostly fructose, which has a lower glycemic index. The glycemic index is a ranking of how much a food would raise your blood sugar compared with pure glucose, which has a ranking of 100. The actual amount any food raises your blood sugar has to do with how glycemic it is, how much of it you eat, and what else you eat with it. The glycemic load attempts to combine these concepts, and some diets use the glycemic load for this reason.

Depending on where you look, the glycemic index of raisins is in the low to moderate range. Keep in mind that glycemic index is a complex topic and individuals can have varying responses to foods. Eating too many raisins can result in a large blood sugar rise in people with diabetes because raisins have a significant amount of carbohydrates per serving.

Fats

Raisins have a negligible amount of unsaturated fat.

Protein

With just under 1 gram of protein per 1-ounce serving, raisins are not a good source of protein.

Vitamins and Minerals

An ounce of raisins provides 4% of your daily needs for potassium. Raisins also contain iron, vitamin B6, vitamin C, magnesium, and calcium.
