During pregnancy, the activity level of pregnant women decreases accordingly, resulting in weight gain and slowing down of metabolism. In addition, the excessive consumption of nourishing foods by pregnant women can lead to weight gain, and in serious cases, it can lead to increased blood lipids, increased blood sugar, and increased total serum cholesterol. High total cholesterol is a risk factor for atherosclerosis, coronary heart disease and stroke. High total cholesterol in pregnant women not only leads to fetal abnormalities, such as premature birth and fetal malformation, but also may increase the risk of vascular accidents and thrombosis in pregnant women. According to the physiological characteristics of pregnant women, the diet during pregnancy should be based on the principles of tonifying the kidneys and calming the fetus, nourishing the spleen and stomach, and nourishing Yin and blood. It is recommended that pregnant women consume pecan porridge and carrot stew in moderation, as both nuts and carrots have a dietary effect of lowering cholesterol. In addition, when stewing chicken soup and other nourishing food, you can properly put some wolfberry, which has the effect of preventing atherosclerosis. Pregnant women should also eat more fresh vegetables and fruits, appropriate consumption of coarse grains, a light diet, and fewer meals. In addition, it is recommended that pregnant women exercise appropriately, which is also beneficial to lower total serum cholesterol.
