Have you had a health professional recommend you drink calcium fortified soy milk?

We hear this often in the plant-based world as a measure to reduce osteoporosis risk. Putting aside the fact that plant milks are not necessary as a source of calcium in a whole food plant based diet, 'calcium fortified' brands may contain vegetable oils without providing substantially more calcium than the 'unfortified' ones. We calculated calcium content of two popular products on a per calorie basis rather than a per volume basis because we eat to meet our calorie needs so it's the calories that matter. We were surprised to find that the non fortified soy milk has a higher calcium content per 100 calories:
Calci Plus = 250 mg calcium per 100 cal
Soy Milky Low Sugar/Lite = 312.5mg calcium per 100 cal

So if you are drinking soy milk for the calcium (which we don't recommend) you are better off choosing the non fortified product without the added oil and sugar. We enjoy small amounts of plant milk as a condiment to our food, rather than a source of nutrition.
