1.What is nutrition? Why is nutrition essential to our daily lives?

“Nutrition is the science that links foods to health and disease. It includes the processes by which the human organism ingests, digests, absorbs, transports, and excretes food substances.” (UOP, 2011). Nutrition is a vital aspect to developing and maintaining good health. Nutrition is essential to our daily lives because it does affect an individual’s quality of life and how long that life is. Lazy lifestyles along with poor diets are risk factors that cause chronic diseases.

2.What is the connection between nutrition and health?
Nutrition and health are directly related. Proper nutrition is necessary in order to have good health. An individual’s health depends on the type of nutrition that individual chooses to consume. There are other factors, but one’s nutrition is extremely vital if not the most important. If an individual is not taking in the appropriate amount of nutrients the potential for health consequences increase.
