Chemical digestion involves the breakdown of food molecules by the use of enzymes to generate simpler molecules that can be absorbed into the body's metabolism.
During chemical digestion, carbohydrates are broken down into simple molecules such as glucose which can be easily absorbed in the small intestines.
Monosaccharides such as glucose are the building blocks of carbohydrates and can be easily absorbed by the body through the small intestines.
Proteins are broken down into amino acids while lipids are broken down into fatty acid and glycerol during chemical digestion.
Some types of fish and shellfish contain healthy omega oils that will help the development of the fetus's nervous system. However, some contain toxins and possibly viruses (oysters, for example) and must be avoided during pregnancy.
