• differentiate between major minerals and trace elements. • state the general functions of the minerals in the body. • state the major functions of each mineral. • identify the best food sources of each mineral. • identify deficiency states associated with each mineral. • identify treatments for mineral deficiencies.

5
Should it be fortified with vitamins and minerals?
Let’s start with a question about alcohol….
Question:
Why is alcohol absorbed more rapidly than the nutrients?
6
How Alcohol Affects the Body Long Term

View the video and come on back when you are finished.
I will have the sound off so I do not disturb the narration.
7
The body wants to dispose of it rapidly.
It is viewed by the body as potentially TOXIC and cannot be stored in the body.
8
A class of organic compounds that contains a hydroxyl group: (OH)
Laymen's terms: An intoxicating agent such as beer, wine and distilled liquor.(ethyl alcohol or ethanol)
9
Ethanol The alcohol in beer, wine, spirits
Methanol Wood alcohol—poisonous

Alcohol is a depressant, not a stimulant.
Alcohol is a narcotic.
Alcohol leads to dehydration.
11
Cerebellum
Pons, Medulla oblongata
Frontal lobe
Midbrain
Two Alcohols: Glycerol and Ethanol
Ethanol is the alcohol in beer,wine, and distilled liquor.
Glycerol is the alcohol usedto make triglycerides.
12
Alcohol is made from grains and fruits isn’t it?
Hmmm…
13
Provides energy7 kcal/g
No other nutritive value
“Empty calories” – does not provide and rather can interfere with nutrient absorption.
14
Fermentation Yeast cells metabolize sugar to make alcohol
Alcoholic beverages Beer: 5–6% alcohol Wine: 8–14% alcohol Liquor: 35–45% alcohol
“Proof” is twice the alcohol percentage

Distillation separates the vitamins and minerals in the original fruit or grain from the alcohol
If these nutrients were kept, alcohol could be used as fuel by the body
Since they are lost, alcohol is viewed by the body as poison
16
To help you decide whether or not alcohol could be or should be fortified let’s make sure you understand how the body processes it.
17
18
12oz beer
1 1/2 oz hard liquor(80 proof whiskey, gin, brandy, rum, vodka)
5 oz wine
Each of these servings equals one drink.
19
Alcohol dehydrogenase:An enzyme that breaks down alcohol in the stomach. Reduces the amount of alcohol absorbed by 20%.
Question: Why do women feel the effects of alcohol faster?
20
21
ONE MINUTE:
The time it takes alcohol to cross the walls of an empty stomach and reach the brain.
22
ONE MINUTE:
The time it takes alcohol to cross the walls of an empty stomach and reach the brain.
23
No digestion required
Absorbed from mouth, esophagus, stomach,and small intestine
Absorption slowed by food
24
25
Venous System(Blood Stream)
Stomach and Small Intestine
Liver
Q: How much can the liver process?
A: ½ ounce ethanol per hour (one drink)
Removing alcohol from circulation Liver metabolism limited Blood alcohol level falls slowly
Individual differences in rate of alcohol metabolism Gender Race/ethnicity Age

AcetaldehydeAlcohol
(ethanol) Acetaldehydedehydrogenase
Acetate Acetyl CoA
CoAAlcohol
dehydrogenase
NAD+ NADH + H+
Using alcohol calories for energy.
Alternate Route for Acetyl CoA: To Fat
Extra fat production from alcohol = weight gain
Remember: 7calories per gram
People who should not consume alcohol Those who cannot moderate intake Children and adolescents Those taking certain medications Those with illnesses worsened by alcohol Those who drive or operate machinery Pregnant or breastfeeding women Those with a strong family history of alcoholism
28
Alcohol in the brain and nervous system Depressant; affects all parts of brain
Alcohol’s effect on GI system Esophagitis, gastritis
29
Alcohol and the liver Fatty liver Fibrosis Cirrhosis
Fetal alcohol syndrome Physical abnormalities Mental retardation Low birth weight; poor growth
30
Alcohol can contribute to body fat and weight gain. (7kcal/gram)
Alcohol has ZERO nutrients.
31
Poor diet Alcohol provides energy but
no nutrients Economic factors Lack of interest in food; GI
problems
Vitamin deficiencies Alcohol interferes with
vitamin metabolism Folate, thiamin,
vitamin A
32
Mineral deficiencies Inadequate diet; fluid losses Calcium, magnesium, iron, zinc Some mineral levels are elevated
Macronutrients Alcohol interferes with amino acid absorption Alcohol raises blood levels of fats
Body weight Inconsistent effect of alcohol calories on weight
33
Displaces nutrients from the diet Interferes with metabolism of nutrients Liver loses its ability to retain folate. Kidneys increase excretion of folate.
Leads to a folate deficiency Excess homocysteine Increased risk for colorectal cancer GI tract cell destruction Deficiency of Thiamin, B12, folate, Vit D, Vit A,
34
Moderate drinking has been associated with reduced mortality
Heart disease Red wine-phytochemical:
ReseveratrolThe “French Paradox”Acts as an antioxidant

Certain populations can benefit from moderate alcohol consumption
However, if alcohol were fortified it would be considered a source of nutrients which would lead to legal difficulties in restricting it’s use
Thank you!
