I love raisins. I’ve always loved raisins. Recently I rediscovered them as a way to help fuel my high demand for carbohydrates/low fat while I train for the Ironman. Because raisins can contain up to 72% sugars by weight, most of which is fructose and glucose, they make a good quick carbohydrate when I need to replenish up to 7,000 calories I need after a long day of training.
If you are trying to lose weight, however, they may not make a good source of carbohydrate. Their glycemic index (GI) is 91. A person attempting to release weight would be better off sticking to lower GI fruit instead.
Raisins have been the object of phytonutrient research primarily for their unique phenol content. According to whfood.org, “The phenols found in fruit have repeatedly been shown to have antioxidant activity and to help prevent oxygen-based damage to cells in the body. The total antioxidant activity of many fruits and vegetables has been found to be exactly parallel to their total phenol content, and raisins take their place in this list right alongside prunes and apricots as an antioxidant-rich fruit. The flavonols (one type of phenol belonging to the flavonoid family) in raisins appear to be least affected by the grape-drying process, but raisins do contain fewer phenols than grapes since many of grape’s phenols are largely lost in the conversion of grapes to raisins. These phenols include the hydroxycinnamics (caftaric and coutaric acids), procyanidins, and flavan-3-ols.”
I learned that you’d not want to let your dog eat them. According to Wikipedia “raisins can cause renal failure in dogs.”
