Which of the following is true about lifestyle habits and pregnancy?Multiple ChoiceRepeated intake of four or more alcoholic drinks at one sitting is harmful to the fetus.Use of tobacco products can be harmful for maternal health but has no impact on the developing fetus.Foodborne illness can be harmful for maternal health but has no impact on the developing fetus.All females must avoid NutraSweet(R) during pregnancy because phenylalanine causes problems with fetal brain development.

The correct answer is: "Repeated intake of four or more alcoholic drinks at one sitting is harmful to the fetus."

This is true because alcohol can cross the placenta and affect the developing fetus, potentially leading to a range of physical and mental developmental problems.

The other options are not entirely correct:

• Use of tobacco products can indeed be harmful for maternal health, but it can also have a significant impact on the developing fetus, including increased risk of premature birth, low birth weight, and developmental problems.

• Foodborne illness can also be harmful for both maternal health and the developing fetus. Certain foodborne illnesses can lead to miscarriage, stillbirth, premature delivery, or life-threatening infection of the newborn.

• While it's true that high levels of phenylalanine can cause problems with fetal brain development, this is primarily a concern for women with a rare genetic disorder called phenylketonuria (PKU). Women without PKU can typically consume NutraSweet (which contains phenylalanine) without harm to the fetus. However, it's always a good idea to discuss diet and nutrition with a healthcare provider during pregnancy.
