need? |- |CORRECT |ANSWER✔✔-DRI |for |protein |depends |on |body |weight |and |stage |of |growth, |
reccommended |.8g/ |kg |of |body |weight |
, -proteins |build |new |tissue, |functional |unit |(enzymes, |hormones, |antibodies), |physiology |and |
metabolism
What |are |marasmus |and |kwashiorkor? |What |causes |each? |What |are |the |symptoms? |- |
CORRECT |ANSWER✔✔--Protein |deficiencies
-Marasmus: |chronic |inadequate |food |intake, |inadequate |energy |and |mineral+protein |intake, |
person |is |lean |and |shriveled |
-Kwashiorkor: |swollen |belly |and |skin |rash, |severe |acute |malnutrition |too |little |protein |to |
support |body |functions
Why |might |a |vegetarian |diet |be |healthier |than |that |of |a |meat |eater? |Why |might |it |be |less |
health? |- |CORRECT |ANSWER✔✔--vegetarian |diet |is |linked |with |reduced |incidence |of |chronic |
disease, |less |obesity, |defense |against |cancer, |less |heart |disease, |less |high |blood |pressure, |may |
help |prevent |disease, |diverticular |disease
- |vegetarian |diets |lack |iron, |zinc, |calcium, |omega |3 |fatty |acids, |vitamin |D |and |Vitamin |B12
What |are |the |problems |associated |with |protein |excess? |- |CORRECT |ANSWER✔✔-obesity, |
health |risks, |animal |protein |sources |have |lots |of |saturated |fat, |calcium |is |spilled |from |urine, |
higher |incidence |of |hip |fractures, |kidney |problems
What |is |a |vitamin? |Fat |soluble |vs |Water |soluble |- |CORRECT |ANSWER✔✔--essential, |organic, |
not |energy-yielding, |micronutrients
-fat |soluble: |greater |body |storage, |don't |need |to |consume |often, |travel |with |protein |carriers, |
requires |bile |juice |for |absorbtion |
-water |soluble: |travel |in |watery |fluids, |excreted |in |urine, |less |body |storage-have |to |consume |
more |frequently
What |vitamins |can |be |synthesized |in |our |bodies? |- |CORRECT |ANSWER✔✔-Vitamin |D |is |
synthesized |in |the |skin.
