9 Healthy Diet

In order to stay healthy it is important to have a balanced
diet — in other words， food that contains something from each
of the three main groups of food． These groups are protein，
carbohydrate and fat．

Proteins are very important for building our bodies； they help
us build new cells as old ones die． Meat and dairy products
are major sources of protein， but not the only ones — we can
also get protein from fish， eggs and beans．

Carbohydrate and fat are important to enable us to store
energy — they provide fuel for the body． Carbohydrates are
found in sugar and in cereals such as rice， maize and wheat．
Fats are found in meats， vegetable oil， butter， and nuts．
Our body also needs minerals such as iron，calcium，and
vitamins．Fish，vegetables and milk contain most of the minerals
we need．Vitamins are found in fresh vegetables and fruit．

健康饮食

为了保持健康，饮食平衡很重要，换句话说，就是食用包含以下三大类的食物。这三大类是蛋白质、碳水化合物和脂肪。

蛋白质对于构建我们的身体非常重要；当旧细胞死亡时，它帮助我们生成新的细胞。肉类和奶制品是蛋白质的主要但非唯一来源，我们还可以从鱼类、蛋类和豆类中获得蛋白质。

碳水化合物和脂肪也很重要，它们使我们能够存储能量，它们为身体加油。碳水化合物可以在糖及谷类诸如大米、玉米、小麦中找到。脂肪可以从肉类、植物油、黄油及坚果中获得。

我们的身体也需要诸如铁、钙、维他命等矿物质。鱼类、蔬菜和牛奶中包含我们所需的大部分矿物质。维他命可以在新鲜的蔬菜和水果中获得
