Early pregnancy symptoms Pregnant mothers should not eat fried dough sticks in the 12th week. When making fried dough sticks, a certain amount of alum is added, and alum is a compound containing aluminum. Generally, the flour used for frying fried dough sticks contains 15 grams of alum per 500 grams. If a pregnant mother eats two fried dough sticks a day, it is equivalent to eating 3 grams of alum. The accumulated amount is quite alarming. Aluminum can enter the fetal brain through the placenta, affecting brain development, thereby increasing the incidence of dementia in infants. Early Pregnancy Symptoms Pregnant mothers should not eat too much chocolate and hawthorn in the 12th week. Eating too much chocolate will make pregnant mothers feel full, which will affect their appetite and lead to a lack of essential nutrients. Pregnant mothers usually prefer to eat sour food, and hawthorn is sour and sweet, and has the benefit of digestion, so it has become the first choice fruit. However, hawthorn has an exciting effect on the uterus, which can cause uterine contractions and possibly miscarriage. It is better to eat less just in case. If you want to eat sour food, choose fresh fruits such as bayberries, cherries, oranges, grapes, and apples. Early Pregnancy Symptoms Pregnant mothers should not eat more instant noodles in the 12th week. As we all know, the human body requires six major nutrients for normal life activities, namely protein, fat, sugar, minerals, vitamins and water. As long as one of these nutrients is lacking, people will get sick over time. The main ingredient of instant noodles is sugar, and the soup contains only a small amount of MSG, salt and other condiments. Even instant noodles with various names such as chicken gravy, beef gravy, shrimp sauce, etc., the content of gravy is very small, which is far from satisfying. It does not contain the amount of nutrients that the human body needs every day, and pregnant women need even more nutrients. Eating too much instant noodles can easily lead to malnutrition in pregnant mothers, which can lead to underweight fetuses. Therefore, pregnant mothers should avoid this food as much as possible or prohibit eating it. Early Pregnancy Symptoms Pregnant mothers can eat green peppers in the 12th week. Green peppers are an ideal food for pregnant mothers to supplement vitamin C. Vitamin C, also known as ascorbic acid, is an important and indispensable vitamin for the human body. It participates in the redox process in the human body and is distributed in various tissues throughout the body. The highest content is in the adrenal cortex, pituitary gland and other tissues, followed by liver and kidney tissues, and the lowest content is in adipose tissue. It can enhance resistance to infection, promote normal bone development and wound healing, especially stimulate hematopoietic function and play a certain role in the maturation of red blood cells. If you are deficient in vitamin C, you will suffer from scurvy, with symptoms such as bleeding in the skin, gums, nosebleeds, and bloody stools. Green peppers are rich in vitamin C. According to measurements, every 500 grams of green pepper contains 525 mg of vitamin C, which is 9 times higher than tomatoes, 3 times higher than Chinese cabbage, 35 times higher than eggplant, and 2 times higher than white radish. It is also rich in protein, fat, sugar, minerals, etc. Green peppers also contain a substance called capsaicin, which can stimulate the secretion of saliva and gastric juice, speed up gastrointestinal peristalsis, and help digestion.
