Q

Mary JO 50 yrOld nurse is lactose intolerant worried about risk of osteoporosis:

Take calcium carbonate with Meals (500 mg twice a day)

Take calcium citrate at bedtime (1000mg)

A

Mary JO 50 yrOld nurse is lactose intolerant worried about risk of osteoporosis:

Take calcium carbonate with Meals (500 mg twice a day) — calcium is best absorbed in an acidic meal — Most efficient absorption in multiple doses.

Take calcium citrate at bedtime (1000mg)

23

No Concern

24
Q

What is the main iron regulatory hormone?

(Upregulated when low.)

A

Hepsidin is main iron regulatory hormone

25
Q

Amount of Dietary Heme vs. non-heme iron

A

About 10% of dietary iron is heme iron

90% is non-heme Iron. — There’s a difference in absorption

26

Absroption, transportation, storage, and excretion of Iron

A
27
Q

Absorption of Iron

28
Q

Enhanced Absorption of Non-Heme Iron

A

MFP – Meat, Fish, Poultry

29
Q

Reduction of Iron Absorption

A
30
Q

Absorbed Iron Requirements

A

Small Numbers because this is not nutritient requirement (RDA) this is absorption which for iron is about 10%
