Food Staple
A food staple is a food that makes up the dominant part of a population’s diet. / Food staples are eaten regularly / and supply a major proportion of a person’s energy and nutritional needs. /
Food staples vary in different places, / depending on the food sources available. / Most food staples are inexpensive, plant-based foods that are full of calories for energy. / There’re more than 50,000 edible plants in the world, / but just 15 of them provide 90 percent of food energy amount that the world’s population take in. /
Food staples traditionally depend on what plants are native to a region. / However, with improvements in agriculture, food storage, and transportation, / some food staples are changing. / Foods that were particular to one region are becoming popular in regions where they don’t traditionally grow. / Although staple foods are nutritious, / they do not provide the full, healthy range of nutritious substances. / People must add other foods to their diets to avoid malnutrition. /
解析
主食
主食是一种食物,它是人们日常饮食中的主要构成部分。主食是人们经常吃的食物,人体所需的能量和营养有很大一部分是由它们提供的。不同地方的主食有所不同,这取决于能找到的食物来源。主食多为便宜且富含热量的植物性食物。全世界有超过5万种可食植物,但其中只有15种为全世界的人口提供90%的食物能量。虽然主食有营养,但是它们并不能提供全面而丰富的营养物质。
