Canned Pineapple Versus Fresh
Ask the Diva: Is Canned Pineapple as Nutritious as Fresh?
Q. Does canned pineapple in natural juice have the same nutrition content as fresh pineapple?
A. Because there’s some heat involved in the canning process, a fair amount of the vitamin C and other heat-sensitive vitamins gets lost in translation. According to NutritionData.com, pineapple canned in juice has only about 60% as much vitamin C as fresh raw pineapple. Nevertheless, a cup of canned pineapple still provides 28% of the Daily Value. Raw pineapple also contains an anti-inflammatory enzyme called bromelain—all of which is destroyed in the canning process.
