A healthy diet is an important premise for you to maintain your health. If you want to keep the body healthy, you should grasp correct dietary skills and maintain a healthy and balanced diet in your daily life. Generally speaking, five dietary skills can help you improve your health. 

First, you can frequently eat whole-wheat foods. According to the research in Harvard University, people who often eat whole-wheat foods can be rarely attacked by heart disease and diabetes. Therefore, in order to prevent various diseases and keep your body healthy, you should increase the intake of whole-wheat foods in your daily life.

Second, you should often eat fruits. More and more doctors advise people to eat some fruits when people have dinner. However, because of various factors, it is impossible for most people to eat adequate fruits each day. One effective way for you to eat enough fruits is to add salad into your dinner. As a result, you can absorb many fruits conveniently. If you do not like to eat salad, you can drink fruit juice or vegetable juice to supplement essential nutrients for your body.

Third, you should control the intake of sugar, chocolate and biscuit. Many people like to drink afternoon tea and eat some snacks. It is important for you to choose suitable snacks which are beneficial to your body. First, you can choose the snacks containing abundant nutrients. These snacks include dark chocolate, fruits, nuts, and so on. Second, you should strictly control the intake of such snacks.

Fourth, you should decrease the intake of red meat so as to protect your heart. One important representative of red meat is beef. Beef is a good source of protein, zinc, iron, folic acid and vitamin B complex. To decrease the intake of red meat does not mean that you must avoid eating red meat. It means that you must eat red meat moderately. If you eat excessive red meat and absorb excessive protein, you will be troubled by the excessive cholesterol left in your body which can block blood vessels. You can eat 500 grams of beef each week.

Fifth, you can frequently eat fish to protect your heart. You can often eat fish to absorb omega-3 fatty acid which plays an important role in decreasing the risks of getting heart disease, diabetes and cancer for your body. It is beneficial for you to absorb 500 milligrams of omega-3 fatty acid every day. If you do not like to eat fish, you can also choose seaweed.
