Final answer:
The correct understanding of nutritional recommendations during pregnancy is the intake increase of folic acid. Pregnant women should avoid harmful substances and focus on consuming essential nutrients, including folate, for the fetus's development.
Step-by-step explanation:
Nutritional recommendations during pregnancy are crucial for the health of both the mother and the developing fetus. The statement "I should increase my intake of folic acid" indicates a correct understanding of these recommendations. Contrary to the misconception of needing to double caloric intake, pregnant women should focus on quality rather than quantity, ensuring they consume adequate amounts of key nutrients such as calories, proteins, lipids, vitamins, and minerals including calcium, iron, and omega-3 fatty acids.
It is essential for expectant mothers to avoid harmful substances like alcohol, illegal drugs, and certain medicines, particularly during the first eight weeks after fertilization when major organs are forming. The Food and Nutrition Board of the Institute of Medicine advises an intake of at least 400 µg/day of folate from supplements or fortified foods to reduce the risk of birth defects. A balanced diet and prenatal vitamins help ensure a healthy pregnancy.
While it is a myth that a woman needs to eat for two in terms of doubling her caloric intake, it is true that all classes of nutrients are vital for survival and that during pregnancy, most nutrients are needed in greater amounts. Engaging in safe exercise routines can also be beneficial, contrary to the belief that exercise is harmful during this period.
