Bread, cereal, rice, and pasta group

6-11 servings a day Includes bread, rolls, biscuits, bagels, grits, oatmeal, rice, noodles, spaghetti, macaroni, and enriched cereals

Aging process of endocrine system

-Less hormone production -Muscle weakness

Related Health problems

-Loss of teeth -Diarrhea -Constipation -Intestinal gas -Impaction

Age processes of the digestive system

-Loss of teeth -Need for calories decrease, but nutritional needs either stay the same or increase -Constipation occurs due to slower peristalsis -Slowed peristalsis causes intestinal gas (flatus) -Saliva production decreases

Functions of digestive system

1. Ingests and prepares food for use by the body 2. Excretes waste
