Alcohol (ethanol) >>> (by ADH) >>>Acetaldehyde (Negative health consequences) >>>(by ALDH) >>> Acetate >>> Fatb.

How fast you break down limited by amount of enzymes you have…II. Health impactsa. Inducible Enzymei. Def: enzymes that are expressed at variable rates (if you need it, you will produce more of it)ii. Produced in Liveriii. People who drink regularly produce this enzyme (those who don’t, do notproduce)iv. Develop tolerance1. Good?...a. Produces free radicalsi. Random damage; attacks cells, DNA, etc. b. Affect Medication; must tell doctor honest answer if asks how much you drink, otherwise you could get a dose too lowc. Turn Pro-carcinogens into carcinogensi. Def Carcinogen: Cancer-causingii. Increased cancer riskb. “Liquid Fat”i. 7kcal/gram1. can contribute to excess energy intake >>> weight gainii. –OH stored as fat1. Inhibits fat burning2. Makes you better at storing fat3. Negative Impact on endurance performancec. Lowers cardiovascular disease riski. When men: 3-9 drinks/weekii. How?1. Raises HDL (good cholesterol)d. Raises blood Pressurei. 2-5 drinks/week: raises 5-10points (Borderline High BP: 140/90)e. “Holiday Heart”i. Cause: 4-6 drinks per sittingii. Starves Heart of Nutrients, feels like Heart Attackf.

Def: Birth defect caused by alcohol consumption during pregnancyii. Biggest cause of mental retardation in US (and most all other countries)iii. No safe time or amount of Alcohol in pregnancy!1. Risk is proportional to how much you consumeiv. Fetus cannot metabolize alcohol1. All negative effects mother might experience are multiplied in fetusv. Syndrome affects executive function more than IQ (higher-order thinking: cause/effect, decision making, impulse control, etc.)vi. Large proportion of prison population has Fetal Alcohol Syndromevii. Child most susceptible during first few weeks of pregnancy 1. Problem: most moms don’t know they’re pregnant at this time!j. Alcoholism (addiction)i.
