Introduction to Nutrition Chapter 1
Food is a basic need for survival: -
people become hungry and search for something to eat when their body needs
nutrients
Nutrients -
the life-sustaining substances in food. These are necessary for the growth,
maintenance, and repair of the body's cells.
Nutrition -
is the scientific study of nutrients and how the body uses them
Humans have no instinctive ability to... -
select the appropriate mix of nutrients their bodies require for proper functioning.
To eat well, people need to learn about the... -
nutritional value of foods and the effects that their can have on health.
diet -
a person's usual pattern of food choices
Simply having information about nutrients and their importance to... -
good health may not be enough for people to change ingrained food-related
behaviors and purchase healthier food: a person must be motivated to makes such changes.
Some people strive to improve their diets because... -
they want to lose or gain weight.
Others are so concerned about their health, they are motivated to change their eating habits in
specific ways, such as... -
by eating fewer salty foods or more whole-grain products.
According to recent analysis of food spending patterns, most Americans... -
do not purchase recommended amounts of fruits, vegetables, whole grains, fish,
and low-fat dairy products.
Americans, however, tend to buy more than recommended amounts of.... -
red meats; candies; cheese; sugary beverages, such as sugar-sweetened fruit and
soft drinks; and refined grain products.
Raw foods often undergo some form of processing, such as... -
refining, canning, freezing, or cooking before they are eaten.
Processing can make a food.... -
more nutritious, safer to eat, and less likely to spoil.
However, some forms of processing remove.... -

There are six classes of nutrients: -

On average, healthy young men and women have similar amounts of... -
vitamins, minerals, and carbohydrates in their bodies, but the young women have

Bodies with high fat content tend to have... -

Cells do not need food to survive, but... -
they need the nutrients in food to carry out their metabolic activities
Metabolism -
is a total of all chemical processes that occur in living cells, including chemical
reactions involved in supplying energy, making proteins, and eliminating waste products
Carbohydrates -
-Major source of energy (most forms)
-Maintenance of normal blood glucose levels
-Elimination of solid waste from gastrointestinal tract (fiber)
Lipids -
-Major source of energy (fat)
-Cellular development, physical growth and development, physical growth and development
