Pregnant women with hypertension should avoid the intake of high salt, high fat and spicy stimulating foods, and avoid overeating and excessive calorie intake. 1, high salt: such as salted vegetables, pickled products, soy sauce, bean paste, hot pot, sausage, etc., if pregnant women consume too much salt, it will cause an increase in extracellular fluid, increased body fluid excretion, resulting in unsatisfactory blood pressure control; 2, high fat: such as animal offal, lard, fatty meat, etc. The consumption of high-fat food is likely to increase the burden on the cardiovascular and cerebrovascular system of pregnant women, causing adverse effects on pregnant women and fetuses; 3, spicy and stimulating food: such as chili, ginger, mustard and strong tea, coffee, etc., stimulating food will lead to vasoconstriction, causing an increase in blood pressure; 4, overeating: irregular diet, unbalanced nutrition, resulting in gastrointestinal tract dysfunction, easily causing abdominal pain, diarrhea and other gastrointestinal symptoms. Severe diarrhea can stimulate uterine contractions leading to preterm delivery; 5. Excessive total energy: monosaccharide substances, such as fructose, sucrose, etc., such substances are likely to cause an increase in blood sugar, which in turn increases the burden on the body and may induce changes in blood pressure. Therefore, pregnant women with hypertension should pay attention to the regular diet and eat light, easily digestible and nutrient-rich food. In daily life, pregnant women should eat more soy products, dairy products, sea fish, etc. to increase protein intake, which is beneficial to the growth and development of the fetus and the health of pregnant women.
