Question:
for example, the staple food of wheat production in northern, southern staple food is rice production
Answer:
rice contains less vitamin B1 , B2, protein, less fat, carbohydrates (more), calcium, phosphorus, iron. Among them, carbohydrates are sugars.
pasta and rice nutrients in almost the same, but all must be a little more, carbohydrates (sugar) content of less. Bread, biscuits sugar content of these foods more more.
can be seen that the grain of rice and noodles were the main suppliers of sugar needed. It is said that one or two of rice or wheat flour, equivalent to 70 milliliters of 50% glucose injection of sugar do. The long-term side will gain weight eating bread
heat 233 cards / 100 grams, 177 calories of rice cards / 100 grams.
the degree of digestion, rice and pasta does not make any difference, are easy to digest food. However, if it does according to weight, water content than the steamed rice, baked buns and other pasta, hence the heat per unit weight of protein
relatively low, although the number of surface proteins in higher than the meter, but in which the quality of the protein than m low. Surface contains 40% of the content of less than 20%, rice protein biological value of grain is higher in common.
the vitamin, the previous standard of living is low, very few non-staple food, eating rice is easily suffer from nutritional deficiency. But now a variety of chicken, fish, meat, eggs for the food, vitamin B1 is no longer a major problem, the advantages of pasta will be difficult to embody.
Chinese:同样是主食,而米和面食营养价值相同吗?
类别: 餐饮食品
问题:
比如,北方主食是小麦制作的,南方主食是水稻制作的
回答:
米饭含有较少的维生素B1、B2，蛋白质、较少的脂肪、碳水化合物（较多）、钙磷铁。其中，碳水化合物就是糖。
面食中营养成份和米饭几乎相同，只是各项都要略多点，碳水化合物（糖）含量差不多。面包饼干这类食品含糖量更多些。
可见，米和面这些粮食主要供应人所需要的糖。据说，一两大米或面粉，抵得上70毫升50%的葡萄糖注射液的含糖量呢。长期食面会长胖
馒头的热量233卡/100克，米饭的热量177卡/100克。
消化程度方面，大米和面食没有什么差别，都是容易消化的食品。但是如果按重量来说呢，米饭含水量比馒头、烙饼等面食高，因而单位重量的热能比较低
在蛋白质方面，虽然面的蛋白质数量比米中高些，但是其中蛋白质的质量却比米低。面中含有40％的“醇溶蛋白”，其中严重缺乏赖氨酸；米中“醇溶蛋白”含量低于20％，米蛋白的生物价值在常见谷类中较高。
在维生素方面，以前生活水平低、副食很少，吃米确实容易患营养缺乏症。可如今各种鸡、鱼、肉、蛋换着吃，维生素B1不再成为主要问题，面食的优势也就难以体现了。
