1, the supply of various nutrients should be sufficient. Food contains a variety of nutrients in the previous we have talked about, which is the material basis of good nutrition. If the amount of nutrients in the diet is not enough, even the best diet can not provide good nutrition. 2. Diversify food and avoid partial diet. Each natural food has its own nutrient characteristics, and its nutrients will not be all-inclusive. Therefore, the nutrients we need daily should be taken from a variety of foods to ensure comprehensive nutrition. A partial diet is likely to miss or reduce the intake of one or more nutrients. Therefore, we advocate a variety of food. 3, food to light, do not consume too much sugar, salt and oil. Sugar, salt and oil can also provide the nutrients we need. But too much sugar, salt and oil is harmful. Excessive intake of sugar may lead to excessive weight gain and may also induce high blood sugar during pregnancy. Excessive salt intake can aggravate edema during pregnancy and hypertension during pregnancy. Too much oil in the diet can likewise cause excessive weight gain and may lead to dyslipidemia. Therefore, you should choose a lighter diet that is rich in nutrients during pregnancy. 4, intake of sufficient water. We recommend that the best drinking water during pregnancy is mineral water or plain water. You can also drink some fresh fruit juice, but it should be controlled and not too much. 5, eat less and more meals. It is easier to be hungry when pregnant, so in addition to 3 main meals, it is best to have 2 to 3 additional meals, which can be arranged between brunch, lunch and dinner and before bedtime. 6.Fresh vegetables and fruits. Provide vitamins, minerals and trace elements as well as dietary fiber for pregnant women and fetuses. However, care should be taken that the amount of fruit should not be too much.
