recommendation of 6 oz/day of _
grains
longest period of time
hunter-gatherer
contains large quantities of bacteria
Large intestine
organ that stores bile
gall bladder
source of glucose obtainable from animals
lactose
disaccharide
lactose
composed of glucose units
maltose, amylose, glycogen
where glycogen is found
liver and muscle
not a source of soluble fiber
lignin
form of carbohydrate most likely to be used directly by the body's cells as energy
glucose
Gluconeogenesis
synthesis of glucose from amino acids
randomization in human clinical trials is necessary in order to
control for differences in the sample population being studied
epidemiological study
the observation of the outcomes of a natural experiment conducted on a population by itself
Clinical trial
type of study can prove a causal relationship most convincingly
human clinical trial
the experimenter needs to control for the placebo effect
stimulates peristalsis
dietary fiber
digestion of starches occurs in which organ(s)
mouth and small intestine
Minerals participate
-in chemical reactions related to acid-base balance
-as catalysts in the synthesis of new compounds
-in the maintenance of cell turgidity
anecdotal evidence
useful in developing questions to formulate a hypothesis
Human studies in nutrition are
high in generalizability, low in control
crop that produces most kcal's/acre
corn
which dietary component has show the least variation throughout history?
protein
saliva contains __ to begin chemical digestion of starch
amylase
main function of stomach
store food for slow release into intestine
water is mainly reabsorbed from food by the
large intestine
muscle tissue is __% water
72
water is __% body weight in an adult
50-60%
acid-bae reactions take place in water because of waters'
tendency to dissociate into hydrogen and hydroxyl ions
not a diuretic
gatorade
not true about photosynthesis
oxygen is a product
not a complex carbohydrate
maltose
monosaccharides
glucose, fructose, calactose
effect of soluble fiber
decrease blood cholesterol
Two types of CHO induce production of the enzymes required to break them down
raffinose and stachyose (found in beans)
ingredient list high in fiber
whole wheat flower, bulgur, corn syrup, maltose
mechanism to raise blood glucose
hormonal
a bowl of cooked brown rice contains
digestible cho and indigestible cho
what has the greatest impact in terms of persons ability to handle ethanol
lean body mass and total body water
consequences of excessive amounts of concentrated sugars
dilute nutritional quality
Human intervention trial
an experiment designed to test how a particular nutrient affects heart disease in humans and includes an experimental group and a control group
Randomizing
in intervention studies, a method of making the treatment and control groups as similar as possible
Disease and diet correlation is due to
overall consumption is higher relative to physical activity
humans have not had time to adapt to the "modern diet"
if you were to drink water without any food, what would absorb most of the water
small intestine
the RDA table
sets nutrient recommendations at levels higher than most healthy people actually need
Which organ most prefers co as its energy source
the brain
glycogen is formed and stored in the liver and muscles when
excessive glucose is present in the blood
Case Control study
matches two individuals in order to see how their different exposure levels to some supposed disease-causing agent effects their likelihood of getting the disease
moderate alcohol intake does Not increase the risk of
heart disease
LEAST likely to be a consideration in human clinical trials
generalizability
lactase and sucrase are produced by cells of the
mucosa
source of protease
stomach
source of amylase
pancreas and salivary glands (for breakdown of starch)
source of bile
liver
function of bile
emulsify fats in tiny drops and suspends it in water
what stimulates peristalis
dietary fiber
typical response of the body to blood glucose
excessive fall in blood glucose triggers the release of glucagon
monosaccharides
glucose, fructose, galactose
Disaccharides
sucrose, maltose, lactose
stored in liver and muscles during high intensity exercise
glycogen
cellulose
found only in plants
mucosa
digestion of disaccharides
soluble fiber
lowers blood levels of cholesterol
slows carbohydrate digestion and moderates blood sugar
calories in carbohydrates
4kcals/gram
