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．

碳水化合物和脂肪也很重要，它們使我們能夠存儲(chǔ)能量，它們?yōu)樯眢w加油。碳水化合物可以在糖及谷類諸如大米、玉米、小麥中找到。脂肪可以從肉類、植物油、黃油及堅(jiān)果中獲得。

我們的身體也需要諸如鐵、鈣、維他命等礦物質(zhì)。魚(yú)類、蔬菜和牛奶中包含我們所需的大部分礦物質(zhì)。維他命可以在新鮮的蔬菜和水果中獲得
