众所皆知,精米、精面的营养价值没有粗制米面的高,因为加工越精细,营养素损失就越大,所以营养学家提倡吃些粗杂粮。然而,食用油脂却不同,精制油品比粗制油既营养又卫生,食用精制油比粗制油更有益健康。 It is well known that the nutritional value of polished rice and refined bread is not as high as the raw rice bread, because the finer the processing is, the greater the nutrient loss is. Therefore, nutritionists advocate eating coarse coarse grains. However, edible oils and fats are different, refined oils are both nutritious and wholesome than crude oils, and edible refined oils are healthier than crude oils.
