Many women pay attention to their diets when they are pregnant, wanting to eat nutritiously and delicately. But, do you know? Many nutritional supplements aren't as healthy as people have always thought, and improper consumption may make them a great enemy of health! If you want to be a healthy pregnant woman, you need to be careful about your diet.
The Misunderstanding of High Calcium
Case: Miss Jin, 30 years old, pregnant woman, "My mom said that older women easily lack calcium, not only resulting in shorter babies, but also easily leading to leg cramps."
Expert Analysis: Pregnant women blindly consuming high-calcium diets, drinking large amounts of milk, taking calcium tablets and vitamin D, etc., is harmful rather than beneficial to the fetus. Nutritionists believe that excessive calcium supplementation for pregnant women can easily lead to kidney stones, and the fetus may develop hypercalcemia, and after birth, the baby may have prematurely closed fontanelles, widened and protruding jawbones, aortic stenosis, etc. Generally speaking, pregnant women need about 800 milligrams of calcium daily in the early stages of pregnancy, and this can increase to 1100 milligrams in the later stages. It is suggested to reasonably obtain calcium from everyday foods like fish, meat, and eggs.
High Protein in Moderation
Case: Miss Wu, 28 years old, pregnant woman, "A colleague told me that if I lacked protein during pregnancy, there would be insufficient breast milk after childbirth. So, I bought a lot of protein powder to eat. After supplementing for a while, I often felt dizzy."
Expert Analysis: Medical research shows that insufficient protein supply can easily lead to physical weakness in pregnant women, slow fetal growth, delayed postpartum recovery, and insufficient lactation. Therefore, pregnant women should consume 120-130 grams of protein daily. However, a high-protein diet during pregnancy can affect the appetite of pregnant women, increase the burden on the gastrointestinal tract, and affect the intake of other nutrients, causing an imbalance in dietary nutrition. Research has confirmed that excessive protein intake can produce large amounts of harmful substances such as hydrogen sulfide and histamine in the body, easily causing bloating, loss of appetite, dizziness, fatigue, etc. At the same time, excessive protein intake can not only increase the nitrogen content in the blood, but also easily lead to increased cholesterol levels, increasing the pressure on the glomerular filtration of the kidneys.
The Misconception of Acidic Foods
Case: Miss Geng, 25 years old, pregnant woman, "I was always feeling nauseous during pregnancy and didn't want to eat. My mother-in-law made me many sour dishes to eat. 'Sour for a boy, spicy for a girl,' so if I want to have a son, I should eat more sour food."
Expert Analysis: German scientists have discovered that the acidity level of fetuses in the early stages of pregnancy is low, and acidic drugs or other acidic substances consumed by the mother can easily accumulate in large quantities in fetal tissues, affecting the normal division and proliferation of embryonic cells, development and growth, and easily inducing genetic mutations, leading to abnormal fetal development. In the later stages of pregnancy, since the fetus is gradually developing and maturing, its cellular acid-base balance approaches that of the mother, reducing the harm caused by these substances. Therefore, pregnant women should avoid taking acidic drugs, eating acidic foods, and drinking acidic beverages during the first two weeks of pregnancy.
