811 men and women - New England Journal of medicine - CORRECT ANSWERS low fat, avg
protein - high carb; low fat, high protein - avg carb; high fat avg protein - low carb; high fat, high protein
- lower carb; 6 months, lost avg 13 pounds; 2 years - maintained 9 pound loss; main finding - none were
statistically significant; best indicator of success - going to meetings; pick the diet that works for you!
Added sugar - CORRECT ANSWERS most women should limit sugar intake to 100 calories or
about 6 teaspoons/day; men 9 teaspoons or about 150 calories/day; America is eating about 475
calories per person per day of added sugars; equal to 30 teaspoons of sugar/day; no adult except those
who are extremely physically active can consume that much added sugar - only athletes like Michael
Phelps
Added sugars and obesity - CORRECT ANSWERS Americans are fatter: greater consumption
of calories; reduction of physical activity; percent of fat consumption has gone down, but amount of
calories has increased. Amount of fat has stayed about the same, percentage, dropped; daily occupation
physical activity has reduced by at least 100 calories/day; epidemiological studies reported inverse
relationship between carbohydrate consumption and fat: more fiber? - healthier diet overall; if consume
a lot of rice or other staple foods; only correlations
animals - CORRECT ANSWERS saturated fat
bacterial in large intestine - CORRECT ANSWERS can digest fiber, but nutrients are absorbed
in small intestine
biggest contributor of protein to the diet - CORRECT ANSWERS beef, poultry, milk,
,bile - CORRECT ANSWERS produced in liver, stored in gall bladder; is an emulsifier - allows
fats to enter cells to be broken down
body regulation of glucose - CORRECT ANSWERS insulin and glucagon; insulin brings glucose
into cells; glucagon breaks glycogen into glucose
body uses glucose - CORRECT ANSWERS first for energy; second for protein; third as fat
can turn - CORRECT ANSWERS glucose to fats, but not fats to glucose
carbohydrate digestion - CORRECT ANSWERS begins in mouth, stops in the stomach, begins
in intestine; sugar is split to yield monosaccharides, which are absorbed in small intestine
Carbohydrates to Glucose Digestion & Absorption - CORRECT ANSWERS Starch and
disaccharides are broken down - Monosaccharides for absorption: Starch :Begins in the mouth;
Digestion stops in the stomach ; Digestion resumes in small intestine
cell membrane - CORRECT ANSWERS phospholipid bilayer - hydrophilic ends on outside,
fatty acids on inside
cellulose - CORRECT ANSWERS fiber - bonds cannot be digested by human enzymes -
excreted
cholesterol production - CORRECT ANSWERS based on genetics
cholesterol - CORRECT ANSWERS key component of bile;
classes of lipids - CORRECT ANSWERS triglycerides, phospholipids, sterols
, complementary proteins - CORRECT ANSWERS need all amino acids in specific amounts; rice
plus beans - get enough of each
complex vs simple carbohydrates - CORRECT ANSWERS simple sugars: monosaccharide and
disaccharide; complex - polysaccharide - starch and fiber
contributors to saturated fats: - CORRECT ANSWERS cheese is #1 contributor to saturated
fat; beef #2; milk #3; oils #4
conversion - CORRECT ANSWERS protein (amino acids) can convert to glucose but glucose
doesn't have nitrogen
denaturing proteins - CORRECT ANSWERS heat or low ph denatures proteins - protein
doesn't function; changes structure;
Diabetes Mellitus - CORRECT ANSWERS prediabetes- blood glucose is elevated but not at
point of diabetes, millions of Americans are at this phase; importance of testing: fasting plasma glucose
test; perils of diabetes: toxic effects of excess glucose, inflammation, poor circulation - amputations
heart disease/effects, eyes affected, kidneys
diabetes - CORRECT ANSWERS pre-diabetes mellititus; is when have hyperglycemia - blood
sugar too high - too much sugar in the blood;
digestible carbohydrates - CORRECT ANSWERS mono, disaccharides, some polysaccharides -
provide bulk and energy; starch
digestion and absorption of glucose - CORRECT ANSWERS starch and disaccharides are
broken down - monosaccharide for absorption; starch: begins in mouth and splits starch into maltose -
glucose +glucose ; digestion stops in stomach; -digestion resumes in small intestine - pancreas
