美国非盈利组织Sightline Institute的学者Jennifer Langston和Eric Hess以美国农业部的水果价格排行为基础，参照有机食品连锁超市Whole Foods Market使用的“总计营养密度指标”（Aggregate Nutrient Density Index），分析了不同水果的营养价值，做出了一个新的价格&营养综合排行：

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.
如果不想多花钱就能买到营养价值最丰富的水果，就请参考以下水果价值排行榜：

Here are their rankings of the best, cheapest fruits to get your vitamins from:
这里是21种水果的价格和营养的综合排行：

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.
所以，最便宜而维他命含量又很丰富的水果就是西瓜、李子、橙子和苹果。

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.
大家都知道浆果很有营养，但是因为价格高，所以排名就比较低。

Bottom line: It's not enough to just buy the cheapest fruit; try buying the cheapest fruit offering the best nutrition for the price.
结论：不要总是买便宜的水果，还要考虑营养成分。
