The premise of dietary control for pregnant women who experience easy tiredness during pregnancy is to supply sufficient nutrition to maintain physiological needs and to ensure the normal growth and development of the fetus, i.e., to control the intake of carbohydrates, proteins and fats, and to ensure the supply of vitamins, minerals, water and dietary fiber. Therefore, the principle of dietary treatment is first of all to pay attention to a balanced diet, the day’s recipes should try to include four basic food groups: grains and cereals, fruits and vegetables, meat and dairy, not partiality, in each category of basic food to choose to eat a variety of different foods. 1, the time interval between the main meal and snack meal Meals should be regular and quantitative, at least 3 meals a day, breakfast, lunch and dinner; each meal includes at least 3 types of food: cereals, meat, fruits and vegetables, chew slowly, do not be too hungry or too full, according to the portion of the meal. It is best to use a small number of meals, such as three main meals plus two additional meals, etc., so that the total food portion of the day is distributed to the meals, to maintain stable blood glucose, not too high or too low. Additional meals can be 1 cup of milk, 1 medium-sized fruit, 1-2 slices of salty bread, 3 slices of salty crackers, 1 egg or 7-8 peanuts, etc., the portion should not be too much; it is best not to eat before going to bed, and try to minimize eating out. 2, the choice of food types Most pregnant women know that they should avoid eating sweets, such as candy, sugar water, cakes, sweet cakes, commercially available beverages and Chinese and Western desserts. When choosing commercially available food, it is important to understand its preparation method and ingredients to ensure safety. Eat as little fried food as possible, reduce animal fat, use vegetable oil when cooking, and use light flavors, less oil and salt. 3. Portion of food eaten in a day The total calorie intake (i.e. the amount of food eaten in a whole day) is calculated according to the standard body weight and intensity of activity, and is determined by taking into account the pregnancy cycle. The calculation method is: standard weight (kg) = height (cm) – 105. Since most pregnant women are at home for leisure or do only a small amount of light work or housework, it is very light work. Normal calorie supply is 25-30 kcal/kg of standard body weight, which depends on the comparison of pre-pregnancy body weight with standard body weight and the activity level. If pre-pregnancy body weight exceeds more than 10% of standard body weight, 25 kcal/kg of standard body weight is chosen; if pre-pregnancy body weight is normal or less than 10% of standard body weight, 30 kcal/kg of standard body weight is chosen; and if it is less than 10% of standard body weight, 35 kcal/kg of standard body weight is chosen. If the weight before pregnancy is normal or less than 10% of the standard weight, then choose 30 kcal/kg standard weight; if more than 10% of the standard weight is lower than the standard weight, then choose 35 kcal/kg standard weight or higher. 4, moderate exercise This point is often the most easily overlooked. Many pregnant women after pregnancy in the family’s care to reduce physical activity, coupled with their own mobility is not convenient to want to move. If you eat too much, it is likely to increase the amount of fat in the body, reduce the sensitivity to insulin, so that blood glucose rises. Therefore, the more easily tired feeling strong pregnant women, the more to do exercise, it is recommended that pregnant women to ensure that more than one hour a day activities, such as walking, shopping shopping, climbing stairs, do pregnant women exercise or ability to do housework, etc..
