摘　　要：“吃彩虹食物”这一营养建议不适用于位于光谱下半部分颜色的食物。虽然自然界中红色、黄色和绿色的食物丰富,但蓝色成分却很难获得。即使是农产品货架上人们耳熟能详的“蓝色”水果,其名字也容易让人误解。杂志《科学进展》上发表的一项新研究解释道:蓝莓不含蓝色色素,这意味着它们不是真正意义上的蓝色。The nutritional advice to"eat the rainbow"gets hard to follow once you reach the bottom half of the light spectrum.While red,yellow,and green foods are plentiful in nature,blue ingredients are much harder to come by.Even the most famously“blue”fruit in the produce aisle has a misleading name.As I new research shared in the journal j Science Advances explains,blueberries contain no blue pigments,which means they're not blue in the true sense of the word.
