No because it is not seen as an essential nutrient

What is the safest way to drink alcohol?
By drinking only 14 units a week which is equal to 140ml.
2 of 16
Alcohol intake in pregnant women can cause what effects?
fetal alcohol syndrome which can physically and mentally affect the newborn.
3 of 16
What does ethanol's structure similarly resemble?
A carbohydrate/sugar
4 of 16
what is Ethanol metabolically similar too?
fatty acids
5 of 16
How is alcohol absorbed?
- it is readily absorbed by the GI tract
- then transported in the blood unaltered
-Then metabolised in the liver by 2 pathways dehydrogenase pathway and cytochrome p-450 system which both leads to acetylaldehyde production.
6 of 16
What does the consumption of too much alcohol cause?
means too much is metabolised so this leads to the accumulation of NADH which causes a metabolic shift and promotes formation of fatty acids
7 of 16
What does the formation of fatty acids cause from too much consumption of alcohol?
It causes fatty acid synthesis and can lead to a fatty liver. This can cause lactic acidosis which leads to vomiting, nausea and abdominal pain.
8 of 16
What are the long term effects of alcohol consumption?
-blurred vision, unconsciousness, reduced coordination, slowed reaction time
9 of 16
Why is too much acetylaldehyde bad for you?
It is highly toxic as it binds to proteins which causes impaired protein function. So, it stops the formation of microtubules in the liver which leads to cirrhosis. This is produced from the 2 pathways in absorption of alcohol.
10 of 16
What causes metabolic imbalance from alcohol?
Alcohol dehydrogenase coverts retinol into retinal which is vitamin A. Habitual drinkers would lack this conversion as the alcohol dehydrogenase would be busy converting ethanol into acetylaldehyde.
11 of 16
What does chronic alcohol consumption induce?
MEOS- microsomal ethanol oxidizing system
12 of 16
What happens to the excess retinol that could not be converted into retinal?
it is oxidised by the MEOS into an inactive metabolite instead of retinal
13 of 16
What does lower production of retinal cause?
It causes hepatic depletion of vitamin A so this means there are elevated vitamin a requirements in alcoholics.
14 of 16
What is the relationship between cancer and alcohol?
It can damage the tissues in the upper GI tract as it is directly exposed to the alcohol.
15 of 16
what are the benefits of alcohol?
-social reasons to relax
- hormesis suggests low levels of challenges such as toxins can promote health through adaptive responses
-helps with decreased levels of LDL cholesterol which is the bad cholesterol.
