第一次世界大战前,医学家发现米糖里含有维生素B_1,可治疗脚气病;1928年,科学家发现水果、蔬菜中含有维生囊C,是预防和治疗坏血病的良药;到1950年,我们所知道的13种维生素都已被发现。因而,营养学界将1910年～1950年这40年,称作营养学的第一个黄金时代。 近几十年,人们从营养不良转到了营养过盛,大量的人患了癌症、心脏病、高血压和糖尿病等“文明瘸”。1982年,美国国家科学院发表了一份研究报告,认为蔬菜、水果特别是大豆制品,将是21世纪的“维生素”。提倡吃大豆,标志着营养学的第二个黄金时代的到来。
Before World War I, medical scientists found that sugar contains vitamin B_1, which can treat beriberi. In 1928, scientists found that fruits and vegetables contain vitamin C, which is a good medicine for the prevention and treatment of scurvy. By 1950 All 13 vitamins we know have been discovered. Thus, nutritionists from 1910 to 1950, 40 years, known as the first golden age of nutrition. In recent decades, people have shifted from malnutrition to overnutrition, with a large number of people suffering from “civilized lame” such as cancer, heart disease, high blood pressure and diabetes. In 1982, the National Academy of Sciences published a research report that vegetables, fruits, especially soy products, will be the 21st century “vitamins.” Advocating to eat soybeans marks the second golden age of nutrition.
