1 gram of etoh has how many calories. A typical glass of dry wine has ? calories
|
One gram of alcohol provides about 7 calories (compared to 4 calories per gram of carbohydrate and 9 calories per gram of fat). A typical glass of dry wine has about 80 calories
|
|
|
are alcohol calories stored? If food is ingested w/ etof are the alcohol calories burned first
|
Unlike carbohydrates and fats, however, alcohol cannot be stored in the body. If alcohol calories are substituted for other calories, no calories will be stored. If alcohol is added to the diet, the calories from alcohol will be burned first and the calories from other sources will be stored, resulting in weight gai
|
|
|
Can alcohol be absorbed from the stomach? What % is absorbed from the small intestine?
|
About 20% of ingested alcohol is absorbed into the bloodstream from the stomach and 80% from the small intestine
|
|
|
Caculate the alcohol by volume and the grams of alcohol consumed in a 4 ounce glass of 12% alcohol wine.
|
12% by vol means there are 12 ml of alcohol in 100 ml of fluid. a 4 ounce glass = 120 ml (30 ml/ounce) therefore in 120 ml of 14% alcohol by volume = 14.0 ml of pure alcohol. since alcohol has a density of 0.8 gm/ 1ml, then 14 0ml has 11.5 grams of alcohol.
|
|
|
how many calories are in a 750 ml bottle of 13% wine.
|
vol of etoh in 750 ml of 13 % wine =
13ml etoh/100ml x 750ml = 97.5 ml of 100% alcohol. Grams of etoh = 97.5 ml x 0.8 gm/ml = 78 grams of etoh. calories per gram of etoh = 7. 7 x 78 = 546 calories |
|
|
what are the units of blood alcohol (BAC)
|
gm etoh/100 ml blood
|
|
|
How much etoh is metabolized in the average person per hour?
|
Alcohol in the bloodstream is metabolized at a rate of about 0.1 gram per kilogram of body weight per hour. A simple equation that approximates the amount of an alcoholic beverage that a person will metabolize is ounces metabolized per hour = wgt (lbs/ 5x % etoh. In one hour a 150 lb person will metabolize the alcohol in 150/(5 x 12) = 2.5 ounces of wine, less than one glass (4 ounces).
|
|
|
Calculate the BAC of an 85 kg male 3 hours after drinking four 6 ounce glasses of 14% etoh wine
|
Grams of etoh consumed = 720 ml x 0.14 ml etoh/100 ml of wine = 100 ml of etoh X 0.8gm/ml (density of etoh) = 80 gms of etoh. divide gms of etoh by total body water = (75% of wgt in kg) = 85 x .75 =
64 liters. 80/64 = 1.25 gm/ liter = .125 gm/dl. subtract the amount metabolized over three hours (0.1gm/kg/hr) = .1 x 85 = 8.5 grams x 3 hours= 25 grams. subtract this from the total # of grams origonally consumed (80 gms) = 55 gms. divide this by the total body water (64L) to get 0.86 gm/liter. divide by 10 to obtain .086 gm/dl of etoh. which is just above the legal limit. |
|
|
how many liters of body fluid does a 100 lb person contain
|
A typical person has 30 liters of body fluid per 100 lbs of weight.
|
|
|
what simple formula can be used to calculate the bac
|
The grams of alcohol consumed can be calculated from the number of drinks, their volume, and the % alcohol of the beverage. A simple equation that closely approximates BAC is .08 x # of drinks X volume in ounces x % etoh all divided by the weight in lbs
|
|
|
What is the BAC of a 150 lb person who drinks 3 six ounce glasses of 14% wine
|
.08 x 14 x 3 x 6 / 150 = 0.134
|
|
|
What is a very simple formula to estimate BAC. use this formula to estimate the bac of a 150lb person who drinks 4 drinks
|
4 x # drinks divided by wgt in lbs.
16/150= .106 |
|
|
What BAC do the following features typically occur?
1)changes in perception and behavior 2)Lack of coordination 3)intoxication becomes obvious 4)passes out 5)comatose 6)death |
Because BAC is a concentration, and not an absolute amount, it affects everyone to the same degree, no matter what their body size. Perception and behavior begin to be affected at BAC's of 0.05 to 0.08 in most people. The legal definition of driving under the influence (DUI) of alcohol is 0.08 in California, but can differ in other states and countries. Lack of coordination is usually evident at 0.10 to 0.15 and intoxication is obvious at 0.20. A person may pass out at 0.30 and become comatose at 0.40. At levels higher than 0.45, death may occur. No one has ever survived after consuming 1 liter of pure alcohol.

what is first pass metabolism?
What % etoh is metabolized in the stomach? what enzyme metabolizes etoh |
ALCOHOL METABOLISM: Metabolism is the breakdown of alcohol to something else, thus lowering the blood alcohol concentration. Almost all alcohol that is ingested is metabolized. Very little is excreted. The first step in alcohol metabolism is the conversion of ethyl alcohol to acetaldehyde by the enzyme alcohol dehydrogenase (ADH). Although most of the alcohol (about 80%) is metabolized in the liver (by hepatic ADH), some (about 20%) is metabolized in the stomach (by gastric ADH) and thus never reaches the bloodstream (and thus does not raise the blood alcohol concentration). Alcohol metabolism in the stomach is called first pass metabolism.

|
Alcohol in the bloodstream is metabolized at a rate of? . A simple equation that approximates the amount of an alcoholic beverage that a person will metabolize in 1 hour
|
Alcohol in the bloodstream is metabolized at a rate of about 0.1 gram per kilogram of body weight per hour. A simple equation that approximates the amount of an alcohol in ounces that a person will metabolizein 1 hour =
wgt in lbs / 5 x # ounces |
|
|
what formula estimates the time in hours it will take to metabolize etoh in one std drink
|
hrs/drink = 250/wgt in lbs
|
|
|
If a person weighs 195 lbs how long will it take to metabolize 3 beers
|
250/195=1.3 hrs/drink
so for 3 drinks = 3.9 hrs. |
|
|
moderate drinkers (1 to 2 drinks per day).has been shown to reduce what medical conditions?
|
A large study by Klatsky of several thousand Kaiser Health Plan members over 10 years demonstrated reduced mortality from all causes, including cancer, heart disease and lung disease, in moderate drinkers (1 to 2 drinks per day).
|
|
|
how many g alcohol/day) have been shown to reduce the risk of heart disease.
|
A study of 50,000 men reported in 1991 by Rimm at Harvard clearly showed that moderate drinking (30 g alcohol/day) reduced the risk of heart disease.
|
|
|
calculate how many ml's of 13% wine = 30grams of etoh
|
13 % etoh by volume = 13 x 0.8 = 10.4 gms/100ml
30/10.4 =2.88 x 100 = 288 mls |
|
|
What factors affect absorbtion of etoh
|
Food Reduces Absorption Rate
– Lower BAC's with Same Alcohol Consumption • Alcohol Concentration – Higher Concentration Increases BAC up to Limit • Carbonation – Sparkling Wines Induce Higher BAC • Gender – Women Have Lower Gastric ADH Levels |
