美國非盈利組織Sightline Institute的學者Jennifer Langston和Eric Hess以美國農(nóng)業(yè)部的水果價格排行為基礎,參照有機食品連鎖超市Whole Foods Market使用的“總計營養(yǎng)密度指標”(Aggregate Nutrient Density Index),分析了不同水果的營養(yǎng)價值,做出了一個新的價格&營養(yǎng)綜合排行: If you want to watch your budget and also buy fruits that provide pretty good
nutrition, below are the choices that offer the best combination of those
factors. Here are their rankings of the best, cheapest fruits to get your vitamins
from: 1. Watermelon So if you want to spend only so much money on fruit, go with watermelon,
plums, oranges and apples to get the most nutrition for relatively little dough.
Everyone knows berries are great sources of vitamins, but they rank low on
this chart because they're pricey. This chart emphasizes both low cost and
nutrition. Bottom line: It's not enough to just buy the cheapest fruit; try buying the
cheapest fruit offering the best nutrition for the price.
