了一些建議。書刊雜志和電視媒體向我們介紹不同保健類型需要的食物和藥品，然而，真正比較好的選擇是花時間和錢買好的食品并且保持飲食的平衡，多鍛煉。
人們應該更多地了解自己的身體以及我們身體所需的養料，以便我們對生活中所面臨的機遇和挑戰有充分的準備。
二、疑難詳解
1. choosing what to eat is no longer as easy as it once was.
我們在選擇吃的東西方面，現在不像過去一樣簡單了。
[問]as在此處作何解釋？
[答]作連詞，表示比較。又如：my hometown is no longer the same as it was. 我的家鄉同過去不一樣了。
2. if we want to keep up with the high pace of modern life, we had better learn to make the right choices about what and how we eat. 如果我們要跟上現代生活的步伐，我們最好學會正確的選擇吃什么以及怎么吃。
[問]如何分析此句？
[答]這里if引導的是條件狀語從句，we had better ...是主句，what and how we eat 是賓語從句做about的賓語。keep up with 趕上，跟上，had better最好。
3. when we choose what to buy and eat, we had better think if the food will give us the nutrients we need. 當我們選擇我們想要買和想要吃東西的時候，我們最好想一想這些食物是否提供了我們所需要的 營養。
[問]這個句子中有三個從句，對嗎？
[答]對。when...， 是時間狀語從句；if...是賓語從句；we need是定語從句。
4. some nutrients help build our body and amke it stronger. 一些食物有助于我們增強體魄。
[問]build our body and make it stronger 一起做help的賓語嗎？
[答]是的。
5. caicium, which is found in eggs, milk and other dairy products, is good for our bones and teeth.
[問]which is found in eggs, milk and other dairy product 是定語從句嗎？

6. other nutrients help keep our body functioning well. 其他的營養物有助于我們的身體正常運轉。
[問]function在這里作動詞嗎？
[答]是的。在這里“起作用”等的意思。
7. but the choices we make are not just about nutrion. 但是，我們做出的選擇不僅是營養方面的。
[問]we make 又是定語從句？
[答]是的。make choices 是“作出選擇”的意思。引導詞which/that 作賓語，可以省去。
8. eating habits become part of who we are: people become vegetarians either because they believe it is healthier not to eat meat or because they so not think we should kill animals for food.
飲食習慣成了我們信仰中不可分割的部分；素食主義者有的認為不吃肉身體要更健康些，有的則是不主張殺動物為食者。
[問]這么長的句子，怎么分析？
[答]主句是：eating habits become part of who we are. eather..., or... 引導兩個because 原因狀語從句。
9. we also make choices based on how the products are grown or made: environmentally friendly foods, or "eco-foods", are made by companies who have tried to use green and clean ways to make the foods. 我們對產品的作出的選擇還決定于生產和加工方式，要是環保性的或者說是生態性的食物，是廠家用綠色而又清潔的方式生產出來的食物。
