Nutrition is
the body’s intake and use of adequate amounts of necessary nutrients for tissue growth and energy production
Nutrients are
the necessary substances obtained from ingested food
Nutrients supply the body with
supply the body with energy
build and maintain bones, muscles, skin
aid in the normal growth and function of each body system
malnutrition is
an imbalance in the amount of nutrient intake and the body’s needs
Overall health is dependent on a combination of
appropriate nutritional intake
adequate exercise
weight management
rest
Poor nutrition, lack of exercise, obesity, and stress contribute to health issues such as
heart disease
some cancers
strokes
hypertension
diabetes or kidney disease
nutrition and immune system
People who practice proper dietary habits have stronger immune systems
Metabolism is
the process of chemically changing nutrients, such as fats and proteins, into end products that are used to meet the energy needs of the body or stored for future use, thereby helping maintain homeostasis in the body
basal metabolic rate (BMR) is
minimum amount of energy required to maintain body functions in the resting, awake state
Metabolism is necessary to maintain life and is composed of two major biochemical processes:
anabolism
catabolism
anabolism is
the use of energy to change simple materials into complex body substances and tissue
catabolism is
the breaking down of substances from complex to simple, resulting in a release of energy
macronutrients are
nutrients that are needed in large amounts
macronutrients are
carbohydrates
fats
proteins
Water
carbohydrates provide
energy for cells, tissues, and organs
fats are
major sources of energy and promote the absorption of vitamins
proteins do what
build, maintain, and repair muscles and tissue
Minerals are
chemicals needed for energy, muscle building, nerve conduction, blood clotting, and immunity to diseases
vitamins are
organic compounds responsible for regulation of body processes, reproduction, and growth
micronutrients are
nutrients needed by the body in limited amounts
micronutrient include
minerals and vitamins
Failure of the body to properly use nutrients can result in
diseases
heart and kidney disease
renal disorders
diabetes
malnutrition
obesity
Obesity is the result of
person’s energy intake consistently exceeding energy use
Carbohydrates are chemical substances composed of
carbon
hydrogen
oxygen molecules
