二战时,深夜作战的英国空军靠什么击落德军飞机呢?按照早前英国食品部的说法,飞行员的制胜法宝是食用胡萝卜!凭借这一宣传,当局号召国民食用更多的本地产蔬菜,特别是富含-胡萝卜素的根茎类蔬菜。当然,几十年后,人们知道了英国皇家空军真正的秘密武器是雷达技术,“胡萝卜说”只是其情报部门的障眼法罢了。那么,胡萝卜真的可以促进视力,还是空穴来风呢?答案是肯定的。在特定情况下,食用胡萝卜的确有助于视力。
In World War II, what the British Air Force fought in the middle of the night was to shoot down the German aircraft? According to the British Food Ministry earlier, the pilot’s magic weapon is carrots! With this publicity, the authorities urged the people to consume more locally grown vegetables, especially Root vegetables rich in carotene. Of course, decades later, people knew that the real secret weapon of the RAF was radar technology, and “carrot” was only a glance of its intelligence services. So, carrot can really promote vision, or groundless? The answer is yes. In certain circumstances, eating carrots does contribute to eyesight.
