8. Is the statement "I can eat as much as I want to during pregnancy because I'm eating for two" really accurate?
8. The statement "I can eat as much as I want to during pregnancy because I'm eating for two" is not really accurate.
1. Heidi's BMI
Heidi's BMI is calculated as follows:
BMI = weight (kg) / height^2 (m)
BMI = 134 * 0.453592 / (1.6764)^2
BMI = 22.5
Heidi's BMI is 22.5, which is considered normal.
2. Weight gain during pregnancy
The recommended amount of weight gain during pregnancy varies depending on the pre-pregnancy BMI. For women with a normal BMI, the recommended weight gain is 25-35 pounds.
3. Calories per day
The number of calories needed per day during pregnancy also varies depending on the pre-pregnancy BMI and activity level. For women with a normal BMI who are moderately active, the recommended calorie intake is 300-500 calories per day more than their pre-pregnancy intake. Therefore, Heidi should consume approximately 2,000-2,300 calories per day during her pregnancy.
4. Food needed in the third trimester
The additional energy needed in the third trimester is approximately 340 calories per day. To estimate the amount of food needed to provide this additional energy, we can use the ADA Exchange System. One Exchange System serving of food provides approximately 50 calories. Therefore, Heidi would need to consume an additional 7 Exchange System servings of food per day in the third trimester.
5. Calcium needs
The DRI for calcium during pregnancy is 1,000 milligrams per day. This is an increase of 300 milligrams per day from the non-pregnant DRI. Good sources of calcium include dairy products, leafy green vegetables, and fortified foods.
6. Iron needs
The DRI for iron during pregnancy is 27 milligrams per day. This is an increase of 9 milligrams per day from the non-pregnant DRI. Good sources of iron include lean meats, beans, lentils, and fortified foods.
7. Folate needs
The DRI for folate during pregnancy is 600 micrograms per day. This is an increase of 400 micrograms per day from the non-pregnant DRI. Good sources of folate include leafy green vegetables, beans, lentils, and fortified foods.
8. "Eating for two"
The statement "I can eat as much as I want to during pregnancy because I'm eating for two" is not really accurate. Pregnant women need to consume approximately 300-500 calories more per day than their non-pregnant intake to support their pregnancy. Eating too much during pregnancy can lead to excessive weight gain and risk of complications.
