Which common fruit juices have the most (and least) phenolic phytonutrients, which may protect against Alzheimer’s disease: apple juice, cranberry cocktail, grape juice (white, red, and purple), grapefruit juice, orange juice, pineapple juice, or pomegranate juice?
Best Fruit Juice, 5.0 out of 5 based on 5 ratings
If phenolics are what's in fruit juice that provides protection against Alzheimers disease, then which juice might be best? They compared apple juice to cranberry cocktail, grape juice—purple, red, and white, grapefruit juice, orange juice, pineapple juice, and pomegranate. Whenever I show brand names, it’s only because they were the actual brands used in the study.
Here’s the graph. As you can see, one really pulls ahead, though the next 5 came out pretty respectable; with a couple phenolic flops at the end. Which do you guess those are? Pineapple… apple apple… and white grape. Who do you think leads the pack? Six left to choose from.… Purple grape #1, then cranberry, pomegranate, grapefruit, orange, and red grape. So there are definitely better choices than apple, though this was for clear apple juice. Cloudy apple juice has more—way more, but that’s because it’s cheating and actually has a tiny bit of the actual fruit in there, that's it's cloudy. So imagine how superior an entire apple would be compared to juice, or even better, a whole pomegranate or whole concord grapes.
So the best fruit juice is the one inside the whole fruit. \
