Osteoporosis Quick Reference Guide Nov 2010.pdf

Key differences in the new 2010 guidelines... 1. lower levels of dietary calcium- now 1200 mg from food and supplements - assess dietary intake first to prevent excess calcium - Approx. 1 cup milk, 3/4 cup yoghurt, hard cheese thumb size- 280-350 mg calcium in each serving, about 200 mg in a multivitamin/mineral supplement and 100-200 mg incidental calcium form variety of food sources, total all sources then assess if supplementation is required. 2. higher levels of vitamin D- 400-1000 IU/day for adults < 50 yrs and 800-2000 IU daily for adults> 50 yrs, - Supplementation is most certainly required since vitamin D is very limited in our daily diet Fish is the largest source 345-530 IU vit D in 3 oz portion, fortified milk has only 100 IU vit D2, 1 tsp margarine has 20 IU and 1 egg has 20 IU. As well as latitude effects, use of sunscreens, variation in conversion to active vit D3 based on skin tone, body weight etc. most Canadian adults (and likely children) will require vitamin D3 supplementation.
