Low to Moderate Amounts of Alcohol
- Drinking a lot is clearly bad for the brain (12-24 drinks per week or more)
- 3-4 drinks per night every night of the week etc.
- Causes neurodegeneration of the neo cortex
- Even for people that drink low to moderate amounts of alcohol.
- One or two drinks per night on average (7-14 drinks per week)
- Evidence of thinning of the neo cortex and other parts of the brain.
“Metabolism” and Empty Calories
- Water soluble and fat soluble
- Can pass into all the cells and tissues in your body
- Ethanol - one type of alcohol
- Toxic
- Substantial damage and stress to cells
- Must be converted to NAD
- Acetaldehyde is poison
- Damages and kills cells
- Ethanol → Acetaldehyde → Acetate
- Acetate can be used as food
- If the body can’t do this conversion fast enough
- Acetaldehyde is built up and cause more damage in the body
- Empty calories
- The entire process is very metabolic costly but there’s no real nutrient value
- Can’t be stored in any beneficial way. No vitamins, no amino acids, no fatty acids.
- Acetate is a terrible food source.
- In essence, when you ingest alcohol, some of it is being shuttled into energy and some of it is being shuttled into a poisonous substance.
Inebriation
- Inebriation is the effect of being poisoned by this substance.
- The range of effects of inebriation are subjective.
- Some people get a real lift for a long time - these people are predisposed for alcoholism.
- Have to be careful with the amount of drinking that they’re doing
- When alcohol gets into the brain
- Has an affinity for particular brain areas
- Slight suppression in the activity of neurons in the pre-frontal cortex
- Disrupts top-down inhibition
- More impulsive behavior
- Memory formation and storage
- Important point➖
- There’s evidence that drinking regularly makes changes to the brains such that more impulsive behavior occurs outside the time that people are drinking.
- And, when they drink, impulsive behavior gets even worse
- This can happen from just one or two nights of regular drinking
- Every Thursday or every Friday
- It increases the number of synapses that controls habitual behavior and reduction in the number of synapses within the neural circuits that are controlling behavior.
- Fortunately, this is reversible.
- From 2 to 6 months these neural circuits return to normal.
Food and Alcohol Absorption
- Eating while inebriated doesn’t help.
- If you eat something prior to drinking alcohol or while ingesting alcohol
- It will slower the absorption of alcohol into the bloodstream
- You won’t feel as drunk.
- The inclusion of all protein, fats and carbs is the most prolific for this
Serotonin
- Responsible for mood and wellbeing
- Studies have shown that serotonin levels can’t alleviate depression and depression-like symptoms. But there’s an important distinction to make:-
- SSRIs can help alleviate depression probably by changing neural circuits. Neuroplasticity.
- Serotonin levels alone can’t alleviate it, but the cascading effects of high serotonin apparently can.
- Alcohol and Serotonin
- Alcohol disrupts those mood circuitry
- At first making them hyperactive (feeling good after a few sips of alcohol)
- After a while though, serotonin levels tend to drop
- As people ingest more drinks there’s zero chance of them recovering that energized mood
- Most people will start to feel more and more suppressed
- There’s a depression of alertness and arousal.
- There’s a subset of people, however, that become more alert.
- These people have a genetic predisposition for alcoholism
- Or they’ve built up such a tolerance
- Everyone should know and recognize their own risk to alcoholism.
