Q

what is food security?

A

Access to sufficient, safe, and nutritious food to maintain a healthy lifestyle. Having sufficient food available on a consistent basis and the resources to obtain appropriate food for a nutritious diet.

Q

what is nutrient density of food?

A

the proportion of essential nutrients to the number of kcals

  • high-nutrient-dense foods provide large amounts of nutrients in relation to the number of kcals (fruits and vegies)
  • low-nutrient-dense foods are high in kcals and low in nutes (sugar and alcohol)

(e.g. glycogen, starches)

  • some poly saccharides cannot be broken down in the body because we dont have the enzymes necessary; those do not contribute to kcals

Q

How much GI secretions and oral intake does the GI tract manage daily?

A

The GI tract manages approximately 8.5 L of GI secretions and 1.5 L of oral intake daily.

The small intestine resorbs 9.5 L daily.

The colon absorbs approximately 0.4 L daily.

The remaining 0.1 L is eliminated via feces.

83
Q

Electrolytes and minerals are absorbed in the ______.

A

colon

84
Q

What vitamins do bacteria synthesize in the GI tract?

A

Bacteria synthesize vitamin K and some B-complex vitamins.

85
Q

what are the two processes of metabolism?

A

metabolism - All biochemical reactions within the cells of the body

anabolism - building
catabolism - breaking down

86
Q

anabolism

A

building of more complex biochemical structures by synthesis of nutrients
(physiologically possible when body is in positive nitrogen balance)

87
Q

catabolism

A

breakdown of biochemical substances into simpler substances
(occurs during a state of negative nitrogen balance)

88
Q

What is required for normal metabolism and anabolism?

A

Normal metabolism and anabolism are physiologically possible when the body is in positive nitrogen balance.

89
Q

What occurs during starvation?

A

Starvation is an example of catabolism when wasting of body tissues occurs.

90
Q

What is required for normal metabolism and anabolism?

A

Normal metabolism and anabolism are physiologically possible when the body is in positive nitrogen balance.

Q

What type of energy is involved in heat production?

A

thermal energy

93
Q

What type of energy is involved in nervous system function?

A

Electrical energy.

94
Q

when does chyme become feces?

A

once it passes through the ileocecal vale between the small intestine and colon

95
Q

what happens to water as feces moves toward the rectum?

A

water absorbs in the mucosa causing feces to become more firm

96
Q

what does exercise and fiber do to peristalsis?

A

stimulates peristalsis

97
Q

100
Q

what is RDA?

A

recommended dietary allowance - the average needs of 98% of the population (not the exact needs of an individual)

101
Q

what is AI?

A

adequate intake - suggested intake for individuals based on observed or experimentally determined estimates of nutrient intakes used when not enough evidence to set RDA

102
Q

what is UL?
