Answer to Question 1

Answer: Digestion begins in the mouth. Chewing mixes saliva with food and begins to break it down. The food travels from the mouth to the stomach through the esophagus. The stomach mixes food with chemicals that break it down further. Most digestion and absorption occurs in the small intestine. Water, vitamins, and some minerals are absorbed in the large intestine. The remaining wastes are passed out of the body in stool.

Answer to Question 2

Answer: It is recommended that after the age of 50, the body needs an increased amount of calcium, and vitamins B6 and D. Older adults have a decreased need for iron and fiber because of the changes in the way an aging body digests food, absorbs nutrients, and excretes waste. The daily recommended amount of vitamin B12 is not changed. However, older adults are encouraged to eat foods with added B12 or take the vitamin as a supplement.

This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
