A healthy breakfast is very important.People who eat breakfast every morning are more active and do better in school or work.A good breakfast should include protein (蛋白质)like eggs or milk,and whole grains(全谷物)like bread or oats.Avoid sugary cereals(含糖表片)because they give you energy only for a short time.. Another interesting fact is about water.Our brain is about 75%water.If we don't drink enough water,we may feel angry or have trouble thinking clearly.So remember to drink water throughout the day. Exercise also helps our mood.When we exercise,our body produces chemicals called endorphins,which make us feel good.Even a 20-minute walk can make a big difference.So if you feel sad or stressed,try going for a walk or doing some sports. In short,a balanced diet and regular exercise are the keys to a healthy body and a happy mind.Start making small changes today,and you will see the difference!
