if beer had more protein in it, would it still be as bad for you?? its basically liquid bread.

What makes it bad is the Alcohol.
Alcohol is basically empty calories and it slows protein synthesis.

to what degree doe4s it hinder protein synthesis? i was going through some old threads but people seem to be in disagreement over how bad drinking is. i'm obcessed w/ working out, but am very ambitious about acheiving my goals. because of this i spend lots of time reading, working out, planning meals, and EATING. i'd hate to throw it away on the weekends when i go and get drunk. after reading some threads last night i was ready to just stay in for the weekend, but reading some more today led me to beleive that it wasn't as bad as thought
*bump* lets hear some more replies this is interesting topic I would want to learn about more. Also same question for hard liqour such as Tuquilla or Vodka
i always figured that alcohol wasnt good for you in general. now that everyone brings up the fact that it hinders protein synthesis, it makes alot more sense, thanks college chemistry, never knew i would actually have anything that would interest me concerning the krebs cycle. replying to monsters question, i would believe that tequilla and liquor aren't as bad on the body, calorie wise. but if you look at it from a strictly alcohol point of view, then of course liquor slows down alot of ****. liquor has a higher percentage of alcohol compared to beer, but beer has alot more calories. so i really dont know which one is worse, beer or liquor??
VIII. Alcohol and Nutrition
A. Chemistry of Alcohol
a. A class of organic compounds containing hydroxyl, -OH, groups
(1) includes many compounds including, glycerol
b. Ethanol, a specific kind of alcohol, often referred to as "alcohol"
a. a lipid solvent
b. Converted to Acetaldehyde
c. Then oxidized to Acetyl CoA
d. Each step uses up a NAD coenzyme (the active form of the B vitamin, niacin)
e. Acetyl CoA can enter Kreb's cycle
B. Alcohol in Beverages
1. Beer 4-6%
2. Wine 8-14%
3. Distilled liquor: Variable:
a. 100 proof = 50%
b. 80 proof = 40%
4. a "drink" = any alcoholic beverage that delivers 1/2 ounce of pure ethanol
a. 12 ounces of beer
b. 10 ounces of wine cooler
c. 4 - 5 ounces of wine
d. 1 1/2 ounces (= 1 jigger) of distilled liquor (80 proof whiskey, scotch, rum, or vodka)
C. Alcohol in the Body
1. As a solvent, ethanol can dissolve lipids out of cell membranes
a. this allows rapid penetration of plasma membrane, resulting in
(1) rapid access to cell structures
(2) destruction of cell structures
(3) death of cells
b. Alcohols are toxic in relatively small amounts
(1) Because the kill microbial cells, they are good disinfectants
a. Euphoria, due to modification of brain function
b. Associated, in low doeses with atherosclerosis
c. Upper limits of acceptable intake for most healthy people
(1) Men (average size): 1 ounce/day]
(2) Women (average size): 1/2 ounce/day
3. Alcohol in the GI (gastrointestinal) tract
a. Because of it lipid solubility,
(1) rapidly absorbed
(2) needs no digestion
(3) on empty stomach
(a) 20% is absorbed directly across the walls of an empty stomach
(b) can reach brain within 1 minute
(4) on full stomach
(a) food has less chance of coming into contact with stomach wall and being absorbed
(b) influence on brain is slightly delayed
(c) Carbohydrate snacks slow absorption
(d) high fat snacks slow peristalsis retention of alcohol in stomach
(e) salt;y snacks thirst
i) drink water, not
ii) more alcohol
(f) Stomach starts detoxification of alcohol with enzyme, alcohol dehydrogenase
i) 20% abosrption to blood stream
a) women have less of the enz;yme
b) hence women become intoxicated on less alsohol than men
(g) Alcohol is rapidly absorbed in the small intestine
(h) Alcohol tends to be metabolized before most nutrients
(i) Alcohol is not stored in the body
(j) Alcohol is potentially toxic
4. Alcohol in the Liver
a. Normally, the liver prefer fatty acids as their fuel and package excessive fatty acids as triglycerides and ship
them out to other tissues in the body
b. Alcohol is taken from GI tract to liver
(1) The liver cells are the only other cells that produce enough alcohol dehydrogenase to oxidase alcohol
at a significant rate
c. Alcohol affects every organ of the body, e.g. the liver
(1) When present, alcohol forces the liver cells to metabolize the alcohol, while letting fatty acids
accumulate (sometimes in large amounts)
(2) Alcohol metabolism also permanently changes liver cell structure
(a) ability to metabolize fats
i) fatty livers in heavy drinkers
d. Maximum rate at which ethanol can be detoxified in the liver = 1/2 ounce per hour (largely determined by the
amount of alcohol dehydrogenase is present.)
(1) Hence: drink slowly enough so that liver can keep up ( 1 drink per hour)
e. Fasting for only one day can cause the body to degrade its own proteins (including alcohol dehydrogenase) for
(1) rate of alcohol metabolism ( 50%)
f. Drinking on an empty stomach onset of effect because -
(1) rapid absorption
(2) slowed breakdown
g. Alcohol acetaldehyde (with help of alcohol dehyrdogenase)
(1) acetaldehyde many side effects of "alcohol"
(2) Acetaldehyde Acetyl CoA (with the help of acetaldehyde dehydrogenase)
(3) Acetyl CoA Kreb's Cycle
h. Liver Problems
(1) NAD needed for Krebs Cycle is in short supply because of amounts need to detoxify alcohol to
(a) blockage of this metabolic pathway
(b) accumulation of Acetyl CoA which is converted to fatty acids (seen after a single night of
heavy drinking) & triglycerides
i) fatty liver
a) activation of vitamin D
b) production of bile
c) interferes with distribution of nutrients and oxygen to the liver cells
d) (if persistent) fibrosis (fibrous scar tissue)
e) [possibly reversible with good nutrition & alcohol abstinence]
f) (ultimately) cirrhosis [irreversible scarring]
g) protein glucose
h) glucose + Acetyl CoA ketone bodies ketosis & acidosis
(2) the excessive conversion of NAD NADH+H leads to acidosis
(3) NADH (pyruvate lactate) lactic acidosis
(a) lactic acidosis interference with uric acid excretion gouty arthritis
(4) Alcohol interferes with protein production by the liver because of deamination of amino acids
(a) amino acids body defenses against infections
i) Eating well won't help; must stop intake of alcohol
(5) Although liver detoxifies other drugs, alcohol is given preferential treatment;
(a) so alcohol drug detoxification drug levels in body (blood)
(b) prolonged alcohol consumption MEOS (microsomal ethanol oxidizing system)
(c) if alcohol consumption is stopped, MEOS detoxification of other drugs & drug levels in
i) This can be a problem for anesthetics
(6) 10% of alcohol in blood is eliminated by lungs and kidneys
(a) Amount in breath & urine is directly proportional to amount in blood
5. Alcohol and the Brain
a. Alcohol is a narcotic
(1) A narotic = "a drug that in moderate doses depresses the central nervous system (brain), thus
relieving pain and produces sleep, but that in excessive doses produces unconsciousness, stupor,
coma, and possibly death"
(2) used as an anesthetic to deaden pain
(a) not very good because the amounts needed is difficult to predict
(3) used as a social anesthetic
(b) relieve anxiety
(c) relieves inhibitions by depressing (sedating) inhibitory nerves
(4) a depressant, not a stimulant
b. Effects on Brain (in order of blood levels)
(1) First affects frontal lobes (the area of reason)
(a) Interferes with reasoning and judgment
(2) Second, affects Speech & Vision centers
(3) Third, affects control of voluntary muscles
(4) Next, affects cerebellum which controls or coordinates voluntary muscle movement (speech, eye,
(a) Walk with a stagger or weave
(b) Slurred speech
(5) Last, unconsiousness, respiration and heart beat, and possibly death
c. Alcohol can kill brain cells
(1) Brain cells (unlike liver or other cells) are not replaced
(2) alcohol use permanent brain damage
6. Alcohol & Water Balance
a. Alcohol ADH production by brain water loss via urination
b. urination water loss and thirts
(1) Replace with water for best healht
(2) Avoid replacing with alsohol which water loss
c. water loss mineral loss
7. Alcohol and Malnutrition
a. May stimulate appetite
(1) caloric intake & fat storage (central obesity = "beer belly")
b. In heavy use, it may substitute for other nutrientes & appetite
c. Alcohol produces euphoria appetite
d. Chronic alsohol use nutrient intake
(1) interferes with metaabolism of nutrients
(a) GI function
(b) conversion of homocysteine to methionine
i) ( homocysteine risk of heart disease)
(c) colorectal cancer
(3) thiamin (a B vitamin)
(a) Wernicke-Korsakoff Syndrome:
i) paralysis of eye muscles
ii) poor muscle coordination
iii) impaired memory
iv) damaged nerves
(1) vitamin B6 deficiency RBC production
f. Toxicity to stomach
(1) gastric acid and histamine production stomach irritation ulcer formation
g. Toxicity to intestinal cells
(1) malabsorption of
(a) B vitamins:
iii) vitamin B12
h. Toxicity ot Eye
(1) affects vitamin A (retinol) in eye
8. Summary of Health Effects of Alcohol Consumption
(1) Atherosclerosis & heart attacks if intake is limited to about 1 drink per day
(3) Fetal Alcohol Syndrome
(4) Heart Disease
(7) Kidney Disease
(8) Liver Disease
(10) Nervous Disorders
(12) Psychological disturbances
alcohol slows down protein synthesis because it dehydrates you, why do you think you piss so much when you drink. Alcohol also lowers your testosterone levels and increases your estrogen levels. This is the why I pretty much stopped drinking all together because I dont wanna be no bitch and I dont need alcohol to have fun.
Yes you dont NEED alcohol to have fun

beer is the highest in carbs which you usually drink at night and then u don't burn those carbs at all. I am sure drinking once or twice a week won't kill ya
I drink to make other people interesting.
--George Jean Nathan
I've consumed approximately 30 drinks in the past week. Whether or not it is inhibiting protein synthesis is insignificant compared to the inhibiting of the brain that generally occurs, causing me to do stupid things.
How bad is smoking and drinking to the body?
My boyfriend gets wasted 3 days out of 7 in the week.
I hate it because I don't drink at all.
He also smokes 4 packs a week, it's just gross.
We are both college atheletes. (soccer)
He's been training all his life, he also plays other sports.
I think his lifestyle really has a negative impact on his health and
game. He always defends himself with the fact that he hasn't
gained any weight. I think that's because he's still in his mid 20's.
Anyway, my question is, how does drinking and smoking impact
the body in the long run?
if alcohol inhibits the release of ADH then why do people say too drink a glass of water between alcoholic beverages???
Water keeps you hydrated. Alcohol is a diuretic. You lose a lot of water when you drink, and then recycle the alcohol into the urinal.
So that you aren't dehydrated.Originally Posted by Beef101
I realize this thread is a year old, but hopefully this will keep another one from popping up for another year....
I think that the reason no one can agree on this subject is because not everyone on the boards has the same goals.
Some people workout to keep bodyfat low and to be healthy.
Some people workout to put on as much mass as humanly possible.
Some people workout to look somewhat decent and to be somewhat healthy.
Some people are training to be professional powerlifters.
Some people are training to be professional bodybuilders.
And moreover, all of these people have varying levels of involvement.
While it might not be worth it to some people to get absolutely wasted, stumble to the bowling alley and make them put the bumpers in because you can barely stand up, then stumble next door to the IHOP and order every single type of food on their menu, then stumble back to the house; it damn well is to me, every once in a while. But I'm not prepping for a contest, so I can afford a 3day setback or however many days this screwed me up.
For me, personally, I'm content if I can see my abs 6 months out of the year and if I'm satisfied with my lifts (which, of course, I never am). This is not the same goal as many others.
The best thing to do is plan what your goals are, first, then you'll know how much alcohol will impede this goals.
