Basal Metabolic Rate (BMR)

Energy (kcals) needed to maintain life-sustaining activities such as breathing, circulation, heart rate and temperature, for a specific period of time at rest.

Things that factor energy requirements

injury, infection, activity level, thyroid function, age, body mass, gender, fever, starvation, menstruation, illness.

Resting Energy Expenditure (REE) or Resting Metabolic Rate

The amount of energy an individual needs to consume over a 24 hour period for the body to maintain all its internal working activities while at rest.

Factors that affect metabolism

illness, pregnancy, lactation, activity level.


Main source of energy in the diet. Each gram of carbogydrate produces 4 kcal and serves as the main source of fuel (glucose) for the brain, skeletal muscles during exercise, erythrocyte and leukocte prodcution, and cell function of the renal medulla.

Foods that contain carbohydrates

Plants and milk products

2 Simple Carbohydrates

Monosaccharides and Disaccharides


Glucose, dextrose, fructose. Cannot be broken down further.


Sucrose, lactose, maltose. Made up of two monosaccharides and water.

Complex Carbohydrate



Glycogen, starches, fiber. Body is unable to break these down. Insoluble in water.


Each gram provides 4 kcal. Essential for body growth and repair. Collagen, hormones, enzymes, DNA, RNA, blood clotting, fluid regulation, acid-base balance.

Amino Acid

Simplist form of a protien.

Food sources of protien

Meats, beans and cheese.

Nitrogen Balance

When enough carbs are in the diet, protien is spared as an energy source. This allows for growth and repair, wound healing, normal pregnancy, maintenance of vital organs. You need a positive nitrogen balance for growth, pregnancy and maintenance of muscle mass and vital organs.

nitrogen balance indicates

Occurs when the body loses more nitrogen then it gains. Infection, sepsis, burns, fever, trauma

Positive Nitrogen Balance

When intake of nitrogen is greater than the output. This allows for growth and repair, wound healing, normal pregnancy, maintenance of vital organs. You need a positive nitrogen balance for growth, pregnancy and maintenance of muscle mass and vital organs.

Fats (Lipids)

Provide 9 kcals/g. Composed of triglycerides and fatty acids.

Saturated Fatty Acids

Each carbon in the chain has two attached hydrogen atoms.

Unsaturated Fatty Acids

Enequal number of hydrogen atoms are attached and the carbon atoms attach to each other with a double bond.

Composition of fatty acids

Chains of carbon and hydrogen atoms with an acid group on one end of the chain and a methy group at the other.

Monounsaturated fatty acid

have one double bond

Polyunsaturated fatty acids

have two or more double bonds.

Linoleic acid

Fat deficiency

Fat intake below 10% of daily nutrition.

Food source with high proportions of saturated fatty acids

animal fats

Food source with high proportions of unsaturated fatty acids

vegetable fats

60-70% of total body weight


Factors that effect unequal intake and output

Illness can increase fluid needs. Some illnesses decrease the ability to excrete fluid, leading to the need for fluid restriction such as renal disease.

How we meet our water intake needs

Ingesting fluids and foods with high water content.

A way the body produces water

During digestions when food is oxidized.


Organic substances present in small amounts in foods that are essential to normal metabolism. They are used as catalysts in biochemical reactions.


Inorganic elements that are essential to the body as catalysts in biochemical reactions.

Fat-soluble vitamins

A, D, E and K. Stored in the fatty compartments of the body. With the exception of vitamin D, these vitamins are provided through dietary intake.

Hypervitaminosis of fat soluble vitamins

Results from megadoses (intentional or unintentional) of supplemental vitamins, excessive amounts in fortified food and large intake of fish oils.

Water-soluble vitamins

C, and B complex (which is 8 vitamins). The body does not store water soluble vitamins, so these need to be provided in the daily intake of food. Although these vitamins are not stored, toxicity can still occur.


Protein like substances that act as catalysts to speed up chemical reactions and are an essential part of the chemistry of digestion.

Salivary glands

Moistens and lubricates food. Amylase digests carbs.




transports food


Stores and churns food. HCL activates enzymes, breaks up food, kills germs. Mucus protects stomach wall. Limited absorption.

Small intestine

Pathway of digestion

Mouth, Phyarynx, Esophagus, Stomach, Small Intestine, Large Intestine, Rectum, Anus


Food leaves the distal stomch, through pyloric sphincter and enters the duodenum, food is now this acidic, liquefied mass.

4 stages of food intake and output

digestion, absorption, metabolism and storage of nutrients, eliminaion


all the biochemical reactions within the cells of the body. Can be anabolic or catabolic


building of more complex biochemical substances by synthesis of nutrients. Occurs in a state of positive nitrogen balance.


Breakdown of biochemical substances into simpler substances and occurs during a state of negative nitrogen balance.


Catabolism of glycogen into glucose, carbon dioxide, and water.


Anabolism of glucose into glycogen for storage.


Catabolism of amino acids and glycerol into glucose for energy.

Dietary Reference Intakes (DRI's)
