These components are processed by cells throughout the body into energy or are used as building blocks. The digestive system is composed of the mouth, pharynx, esophagus, stomach, small intestine, large intestine (or colon), rectum, and anus. There are four steps in the digestion process: ingestion, the breakdown of food, nutrient absorption, and elimination of indigestible food.

The hypothalamus triggers feelings of either hunger or satiety (fullness) by integrating signals from nerve cells, hormones, and the amount and type of food we eat.

B12 is crucial for methionine synthesis and cellular metabolism. Assessing B12 status typically involves dietary intake and serum levels, though total serum B12 has limitations.

Plant-based alternatives often need fortification, which may be ineffective. Foods like canned fish and leafy greens also offer calcium but can have low absorption rates. Certain preparation methods enhance calcium content.

Absorption rates depend on dietary intake, with lower intake increasing efficiency and higher intake decreasing it. Active transport and passive diffusion facilitate absorption, the latter making up 90% of it. Factors like calcium and fiber can inhibit absorption, while vitamin D enhances it.
