calcium or more per day delivered fewer preterm babies than those women with a lower calcium intake. Calcium supplementation did not have a detectable effect on the risk of low birth weight, admissions to neonatal intensive care unit, stillbirths or neonatal death before hospital discharge.
The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. In chemical digestion, enzymes break down food into the small molecules the body can use.
Breaking down of food occurs in multiple places 1) salivary amylases break down simple sugars 2) pepsin in the stomach breaks down some proteins 3) digestio â¦ n is completed in the duodenum of the small instestine by pancreatic amylases, lipases, and peptidases (trypsin and chymotripsin) which break down sugar, fats, and proteins respectively.
