Rice will not eat fat?
Often hear people say, "Do not eat too much rice, eat more easily gain weight!" Not afraid to eat without effort, the lack of nutrition, eat more fat and fear. If so, just what we should or should not eat white rice?
In fact, white rice is one of the many food, energy and nutrition is a major source of our food through the digestive system will convert the body heat necessary to meet the body's metabolism and the basis of day-to-day work activities.
Rice is one of our most of the crops eat types of food one. From the point of view of nutrition, rice can provide starch, belongs to a carbohydrate; diet is the main source of heat, the body is the preferred source of heat.
Carbohydrates can be divided into sugar (glucose, including single-and dual-sugar), starch and the three main types of dietary fiber, sugar, syrup and honey are rich in single-or dual-sugar candy; As for the cereal (such as rice) and roots Vegetables rich in dietary fiber and starch, and per gram of carbohydrate provides 4,000 calories, carbohydrates to draw on, we can cereal products (such as cereals, bread, rice, noodle), calories, vegetables, milk and Found in beans. .
According to nutritionists recommended in the study, we meals per day, total carbohydrates should be on total energy of 60% to 70%. An adult female, for example: every day should be eating about 3-6 types of food crops were.
To maintain daily life and metabolism, we have sufficient intake of carbohydrates, in order to lose weight and get rid of all food crops, Meat change, or eating only fruit to eat, may absorb more heat (depending on the cooking methods and Weight eating), increased fat. On the contrary, eating too much, will constitute a heat supply overgrown, the same lead to obesity. Therefore, white rice and does not equate obesity. As for the size of a meal, according to their height, weight and activity levels.
吃米饭会不会发胖?
经常听到别人说“千万不要吃太多米饭,多吃会很容易长胖!”不吃饭又怕无力气,欠缺营养,多吃又害怕肥胖。那究竟我们应不应该吃白米饭?
其实,白米饭也是众多食物其中的一种,是提供能量和营养的主要来源,我们透过消化系统将食物转换成身体所需的热量,以应付身体的基础新陈代谢和日常工作、活动等。
大米是我们最常吃的五谷类食物之一。从营养角度来说,大米能提供淀粉质,属于碳水化合物的一种;是日常饮食中热量的主要来源,也是身体热量来源的首选。
碳水化合物可分为糖(包括单糖和双糖)、淀粉质及膳食纤维三大类,其中糖类、糖浆和蜜糖都含丰富的单糖或双糖;至于谷物(如大米)和根茎类蔬菜含丰富的淀粉质及膳食纤维,而每克碳水化合物能提供4000卡路里,要吸取碳水化合物,我们可以从谷类产品(如麦片、面包、大米、粉面)、热量、蔬菜、牛奶和豆类中找到。。
据营养学家研究建议,我们每天膳食当中,碳水化合物应占全日总能量的60%~70%。以一个成年女性为例:大约每天应该吃3至6份的五谷类食物。
要维持日常生活和新陈代谢,我们要摄取足够的碳水化合物,若为了减肥而戒除所有五谷类食物,改吃肉类,或只吃生果充饥,可能会吸收更多热量(视乎煮的方法和进食分量),增加发胖的机会。相反,吃饭过多,亦会构成热量供应过盛的情况,同样引发肥胖。所以白米饭与肥胖并非划上等号。至于吃饭多寡,要按照自己的身高、体重、活动量而定。
