Q

What is the FFM composed of and how do their energy requirements rate??

A

increased blood volume –> low ER
skeletal muscle mass –> moderate
fetal and uterine tissues –>High

Q

How did we calculate the increased energy requirement during pregnancy?

A

using the amount of tissue deposition during the pregnancy

and maintenance of tissue already deposited

Q

Why do we not use the regular amount of 4kcla/g or 9kcal/g for the calculation of energy requirement during pregnancy?

A

Protein and fat has more energy than that. 4 and 9 take into account the digestible energy and metabolically available energy BUT you need energy to put protein together

Q

Why is there a steady decrease in PAL during pregnancy?

A

PAL=TEE/BEE with BEE increasing much faster than TEE

Q

What composes the EER of a women during pregnancy?

A

EER=Sum of TEE of the women (prepreg) + median change in TEE of 8kcal/week + energy disposition of 180 kcal/day

12
Q

TRUE OR FALSE. Protein requirements are the same for the whole pregnancy.

A

FALSE. protein requirements vary with each trimester to sustain growth and sustain the protein that was accumulated at the end of each trimester

Q

How was the EAR for protein requirements determined for pregnant women?

A

Taking a look at weight gain for each trimester and determine the additional protein needed to sustain the new weight (accumulated protein) and the new deposition of protein.
average the 2 last trimesters to get the EAR

Q

How does pregnancy affect the requirement of omega 6 and omega 3 fatty acids?

A

need more because more energy

17
Q

How was the AI for omega 6 and omega 3 determined?

A

based on highest median intake of healthy population.

18
Q

What is the relation between birth weight and omega 3, 6 and 9

A

Low levels of omega 3 and 6 with high levels of omega 9 (mead acid) can lead to LBW

19
Q

What happens with low levels of omega 3 and omega 6?

A

The desaturases are going to go after omega 9 to make mead acid

20
Q

What is an indicator of essential fatty acid deficiency?

A

High Mead Acid in the blood

21
Q

What is the ideal range of the ration of omega 6 to omega 3 fatty acids?

A

4/1 to 10/1 max

22
Q

What happens with a diet excessive in omega 6 fatty acids that disrupts the balance?

A

favors formation of arachidonic acid and less DHA is produced. Can pose a risk for brain development

23
Q

What affects the carbohydrate requirement during pregnancy?

A

increased metabolic rate (need more fuel)
first is for growth and development then just growth
the hormones produced blunts the effect of insulin to free up CHO for the fetus

24
Q

TRUE or FALSE. The fetal brain can use ketoacids.

A

TRUE

25
Q

TRUE or FALSE. Increasing fiber consumption for pregnant women above the AI for normal women has extra beneficial effects.

A

FALSE. No extra effects that is why the AI is maintained.

26
Q

Why is there no EAR for water?

A

Too much variation on too many factors

27
Q

What is the AI based on for water in pregnant women?

A

Median total water intake that healthy pregnant women consume.

28
Q

TRUE or FALSE. The calculation for the AI for water in pregnant women includes intake of water from food.

A

TRUE
