There is no such thing as “good for you” in nutrition, as long as the food is consumed in the right amount, it can provide the body with certain nutritional value. The most important thing is to have a diversified and balanced diet. According to the Dietary Guidelines for Chinese Residents, every adult needs to consume 1,500 to 1,700 milliliters of water, 250 to 400 grams of cereals and potatoes, 300 to 500 grams of vegetables, and 200 to 350 milligrams of fruits every day. Meanwhile, healthy adults need 40 to 75 grams of livestock and poultry meat; 40 to 75 grams of meat from aquatic products; and 40 to 50 grams of eggs; 25 to 35 grams of soybeans and nuts; 300 to 500 grams of milk and its dairy products; less than 5 grams of salt, and 25 grams to 30 grams of oil per day. Only by achieving a balanced nutrition and a rich and diversified diet can we ensure the diverse nutritional needs of the human body and maintain good health. So in ordinary life can not pick food, not partiality, as much as possible more intake of more varieties of food.
