如何保持身体的健康
1、规律的作息习惯
人体的各大器官经过一天的消耗，必须得到合理的休息方可恢复。颠倒生物钟的作息，只会给身体留下不可抹灭的痕迹。应摒弃日夜颠倒的做法，养成规律的作息习惯。
2、均衡的饮食习惯
大肠癌年轻化与其饮食习惯有着密不可分的关系。年轻人喜好烧烤、腌制、高脂肪、高热量食品，较少摄入蔬菜、水果、粗粮；失衡的饮食习惯易导致胃肠道紊乱，加重了患癌的风险。另外年轻人追求快节奏的生活方式，通常外卖代餐。但“外卖品”本身缺乏均衡的营养，“毒大米”、“地沟油”并存，在配送过程中易滋生细菌等等诸多不良因素集于一身，长期的进食，只会百害而无一利。
3、适当的体育锻炼
首先明确的是，金钱不能换来健康，过度的消耗身体，只会换来后悔。年轻人人除了“管住嘴”外、也需要“迈开腿”，多参与室外运动，体育锻炼，强化身心。
4、定期的身体检查
癌症不是一朝一夕地凭空出现的，其发展是有一个过程的。如息肉发展为癌的历程是：正常黏膜——小息肉——大息肉——高级别内瘤变——癌前病变——癌；这过程一般需要5-15年时间（但个体存差异）。通过定期的体检，能很好地干预疾病的发生，在源头上杜绝其衍生。但很多年轻人身体出现小症状不以为是，能拖则拖，能扛则扛，自行以药物打发；以致被发现患癌时，大多为晚期，失去最佳的治疗时间。

例文：People are beginning to attach much more importance to their health these days than ever before. They begin to realize that good healthis the most valuable possession a person can have. However, many people don't know how to stay healthy although great efforts have been made in this regard. In my opinion, there are three things we can do if we want to be in good.
First, we should have the right food, because proper nutrition is the most important for good health. Avoid foods with lots of sugar and fat. Eat plenty of high protein foods, vegetables and fruits. Do not overeat. Secondly, we should get proper amount of sleep, because without enough sleep, we will often feel tired and irritable. Allow ourselves at least eight hours of sleep each day. Have a nap at noon if time permits. Finally, we should exercise regularly, because'life depends on exercise'. Regular exercise strengthens our hearts andlungs. In addition, it prevents us from putting on weight.
If everyone is to do so, there will be much less complaining about poor health and there will be much more happiness in our life.
