Calcium is very important to the organism, and different factors influence its absorption. Pregnancy, Infancy, Vitamine D increase calcium absorption. Oxalic acid, phytic acids, and being over 70 years old decreases absorption
------------------------------------------
Calcium is a highly significant mineral for the appropriate development and functioning of the organism.
Different factors influence the mineral absorption, favoring it or limiting it.
Among the factors that might favor calcium absorption, we can mention
In the second and third trimesters of pregnancy, calcium absorption is the greatest. The intestinal absorption of calcium in women during this period increases to meet different demands. Calciotropic hormones are involved in the process.
Vitamine D is one of the principal factors involved in calcium regulation. Vitamine D helps to double calcium absorption through the thin intestine.
During infancy, the body is growing, bones are developing, and the body needs to consume a high amount of calcium to accomplish these functions.
Calcium is a baseline mineral to provide children while growing, especially in their first periods of life.
Among the factors that limit calcium absorption, we can mention
Elder people consume less food, and together with food consumption decrease, a less amount of necessary mineral is consumed.
With aging, calcium absorption decreases approximately 20% in the intestine.
Many substances, together with ingested calcium, form compounds that impede mineral absorption through the small intestine.
So in the presence of substances such as oxalic acid and phytic acid, calcium absorption is limited.
It is recommended not to consume food rich in calcium and food rich in these other substances simultaneously.
