Raisins, sultanas, and currants are all types of dried grapes. They are nutrient-dense and calorie-dense due to the drying process. Raisins are commonly found in supermarkets, and different drying methods or grape types can result in various flavors and textures. Sultanas, often called golden raisins, are made from Thompson Seedless grapes and are lighter in color due to a sulfur dioxide solution and quicker drying process. Currants, made from Black Corinth grapes, are smaller and tangier than other raisins. All types of raisins are rich in antioxidants, fiber, potassium, and iron, which contribute to better heart health, lower risk of chronic diseases, improved gastrointestinal health, better oral health, and lower risk of anemia. However, they should be consumed in moderation due to their high sugar content and calorie density. Potential drawbacks include unwanted weight gain, stomach discomfort from too much fiber, and pesticide concerns. Despite these, raisins can be a healthy snack option if eaten in small portions.
