True
How many calories come from alcohol?
7 calories/gram
What % of calories come from alcohol for adults who drink? For heavy drinkers?
regular consumers: 3-9%
heavy drinkers: 50%
What happens to diet quality when you increase alcohol consumption?
decreases
What type of calories come from alcohol?
empty calories
Where is the alcohol easily and rapidly absorbed?
stomach and small intestine
What needs to happen to alcohol in order for it to leave the blood and body tissue?
needs to be broken down by the liver and used for energy or converted into fat and stored
Is alcohol stored?
No, remains in body until eliminated
What % of alcohol is eliminated directly without being metabolized?
10%
Body treats alcohol as a toxin and begins elimination immediately
How is alcohol eliminated without being metabolized?
Exhaled via lungs, and the rest via sweat, saliva and urine
What % of alcohol that enters the body is eventually completely oxidized?
90%
Why is a small amount of alcohol metabolized in the stomach?
because it has a small amount of alcohol dehydrogenase
rest is metabolized by the liver
Why do women have lower alcohol tolerances?
- women have lower amounts of alcohol dehydrogenase (more alcohol goes right to bloodstream)
- women have more body fat and less body water (alcohol is dispersed in body water - women reach higher peak alcohol concentrations then men)
- women have lower blood volume
What is blood alcohol concentrations (BAC) determined by?
- amount of alcohol consumed
- presence or absence of food
- rate of alcohol metabolism
What can increase alcohol absorption rates?
- drinking on an empty stomach
- drinking highly concentrated alcohol
- carbonated beverages
How can alcohol absorption be slowed?
- eating before or while drinking
- diluting drinks with water or fruit juice
3.

1
What does the amount of alcohol dehydrogenase depend on?
genetics and how recently you have eaten
How does alcohol damage the liver?
3 things
- fatty liver - fat accumalates
- fibrosis - liver cells die and form scar tissue
- cirrhosis - damage least reversible
How does alcohol affect behaviour? Briefly explain.
3 things
- depresses the behavioural inhibitory centers (more talkative, more self-confident and less socially inhibited)
- slows down processing of information from the senses (trouble seeing, hearing, smelling, touching and tasting, and threshold for pain is raised
- inhibits thought processes (poor judgment and clouded thinking)
Can you sober up by walking around the block?
No, muscles cannot metabolize alcohol, only the liver can
Can a cup of coffee sober you up?
No, it is a stimulant but won’t speed up metabolism
Why is it bad to drink along with other drugs such as sleeping pills, antidepressants and painkillers?
alcohol metabolism competes for detoxification system in liver so drugs build up (body wants to remove both toxins but cannot remove both at the same time)
When can occur when you drink and take aspirin or ibuprofen?
when done frequently
stomach ulcers and bleeding
When can occur when you drink and take acetominophen?
when done frequently
liver damage
When can occur when you drink and take sedatives or narcotics?
severe sedation
What does taurine do?
In redbull, with respect to alcohol
can alter the locomotor stimulatory, sedating and motivational effects of ethanol in a strongly does-dependent manner
Why is mixing redbull and alcohol dangerous?
RedBull can mask the effects of alcohol - it is a stimulant while alcohol is a depressant
