While all berries offer health benefits, raspberries are one of the highest-fiber picks you can find. A cup of fresh raspberries has 65 calories and eight grams of fiber, while a cup of frozen raspberries has about 75 calories and a whopping nine grams of fiber. Their high fiber counts will keep you satisfied longer and help control cravings. They’re also an excellent source of vitamin C and manganese. Phytonutrients in red raspberries — including anthocyanins, procyanidins, flavonols and ellagic acid — reduce inflammation, oxidative stress, and protect against free-radical-induced cell damage, all of which are implicated in chronic diseases such as heart disease, cancer, Type 2 diabetes and declines in cognitive function.
