- 1/3 of calorie need in pregnancy related to increase work of heart.
- another 1/3 needs for respiration and accretion of breast tissue, uterine muscle,placenta.
- second trimester; energy is added 360kcal/day
- third trimester; energy is added 470 kcal/day

2.Need for carbohydrate
- minimum 175g in order to meet fetal's brain need for glucose.

- if ingested, it'll pass thru placenta to fetus and can interrupt normal growth and development.
- lead to abnormal mental development.
- NO clearly defined safe level of alcohol intake during pregnancy.

- +25g/day or 71g/day or 1.1g/day x body weight (for age 14 years old and above)
-Protein requirement increase due to protein tissue accretion
-RNI Malaysia, added 7.5g/day of protein
