The juice that's worth the squeeze

Pucker up! A recent study published in the Journal of Food Science states that pink grapefruit juice is the most nutritious. Orange juice ran a close second, with white grapefruit, pineapple, prune, grape, and apple juices lagging behind. Pink grapefruit juice (the 100%, no-sugar variety) packs a bigger nutrition punch per calorie than any other 100% fruit juice.

One tart and tangy glass of pink grapefruit juice provides 100% of a day's vitamin C. It also provides nutrients such as potassium, folate, lycopene, thiamin, and magnesium. Sugar-added juices, juice cocktails, and other blends were not included in the study.

When pouring yourself a glass of juice, be sure to check the serving size and calories per serving. Even no-sugar-added juices can be high in calories, and the serving size may be smaller than you think.
