1. The supply of various nutrients should be adequate. Food contains a variety of nutrients in the previous we have talked about, which is the material basis of good nutrition. If the intake of nutrients in the diet is insufficient, even the best diet will not be able to provide good nutrition. 2. Diversify food and avoid partiality. Every natural food has its own nutrient characteristics, and its nutrients will not be all-encompassing. Therefore, the nutrients we need every day should be taken from a variety of foods to ensure comprehensive nutrition. A partial diet is likely to omit or reduce the intake of a certain nutrient or a few nutrients. Therefore, we advocate diversification of food varieties.3. Food should be light and not excessive in sugar, salt and oil. Sugar, salt and oil can also provide the nutrients we need. However, too much sugar, salt and oil are harmful. Excessive intake of sugar may lead to excessive weight gain and may induce high blood sugar during pregnancy. Excessive salt intake can aggravate edema in pregnancy and high blood pressure in pregnancy. Too much oil in the diet can likewise cause excessive weight gain and may lead to dyslipidemia. Therefore, you should choose a light diet rich in nutrients during pregnancy. 4. Adequate water intake. We suggest 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. Pregnancy is easier to hunger, so in addition to three main meals, it is best to have two to three additional meals, which can be arranged between brunch, lunch and dinner and before bedtime. 6, fresh vegetables and fruits. For pregnant women and the fetus to provide vitamins, minerals and trace elements and dietary fiber. But should pay attention to the amount of fruit should not be too much.
