Carbs main function
provide energy
Simple Carbs
Simple Sugars: monosaccharides, disaccharides
Complex Carbs
Polysaccharides
Starch, Glycogen, Dietary Fiber
(not sweet, C6H12O6)
Can we digest Dietary Fiber?
NO. it is the one carb we don’t use for energy
Carbs broken down into
Glucose to make ATP
The simplest carb is…
Glucose

Fat - 9 kcal/g Carb - 4 kcal/g Protein - 4 kcal/g ETOH - 7 kcal/fl oz (amount of heat required to raise 1cc of H2O 1degree
Can we digest Dietary Fiber?
NO. it is the ONLY carb we don’t use for energy. Helps move food through intestines
Carbs broken down into
Glucose (fuel) to make ATP (fire)
The simplest carb is…
Glucose
Merasmus
starvation
All sugars/carbs broken down into
Glucose
Fats provide
Satiety
Glucose stored where?
Liver and Muscles
Extra Glucose stored as?
Fat
Insulin allows Glucose into cells to be used for ATP
.
Glycogen stored where?
Liver, muscles
When full it is converted to fat
If energy needs met, carbs stored as?
Glycogen
If glycogen store full, excess carbs converted to ?
Fat
Fats and cholesterol are ?
Lipids
Adipose functions
Cushioning
Insulation
Cholesterol needed for
- Integrity of cells
- Vit D synthesis
Fat provides satiety and adds flavor and aroma to foods
Aka ?
Umami
Vege based sat fat (very few)
Coconut oil
Unsaturated Fatty Acids
One or more bonds of missing H
Monounsaturated (can take 1 more H)
polyunsaturated ( can take a few more H)
Plant sources
Liquid at room temp
Blood cholesterol lowering properties
Monounsaturated (can take 1 more H)
polyunsaturated ( can take a few more H)
Mono- thicker oils (avocado, olive)
Poly - thinner ( sesame, walnut, sunflower)
Fats (lipids)
Trans fatty acids
Unsaturated fats made into sat fats in lab by adding H. They become solid in room temp.
Cholesterol
Provides no energy Synthesized in liver Foods of animal origin Highest in shrimp/lobster No more than 300mg per day
Bile doesn’t break down fats, it …..
Emulsifies
Fatty stool, float or sink?
Floats
also in people without a gall bladder. bile is not deposited into duodenum to start emulsification so most fat is excreted with stool.
Lipoproteins (LDL, HDL) facilitate transport of ?what to ?where
lipids to bloodstream
Where is Lipase made and what does it do?
made in pancreas
breaks down lipids
HDL, LDL
difference? Which is good/bad?
HDL, tighter membrane
LDL, loose wall. WBS eat and die. They become so full and become foam cells, stick to wall. Atherosclerosis
Saturated fatty acids
Chem bonds completely filled w H
Generally or ANIMAL origin
Solid at room temp
Raise cholesterol levels and risk for atherosclerosis
Lard, margarine, suit
Protein made up of ….
amino acids
How many Amino acids? How many considered essential?
22, 9 essential
Essential Amino Acids
Not produced by the body. Must be obtained from diet
Complete Proteins
contains all 9 essential amino acids, of animal origin (meat, poultry, fish, milk, cheese, eggs
Incomplete Proteins
lacking one or more essential amino acids, of plant origin (grains, legumes, nuts, seeds)
Soy is the highest non-meat source of protein
contains PhytoEstrogen
Lactovegetarian
vegetarian plus dairy products
Lacto-ovo-vegetarian
vegetarian plus dairy and eggs
Create complete proteins by eating things together…
mac and cheese
peanut butter and jelly
rice and beans
Kwashiorkor malnutrition
severe protein deficiency. kids mainly. only eat rice and wheat, no protein. Causes edema. Solutes attract H2O out into intersticial. starving kids with big bellies. Change in hair color. body no longer produces melanin.
Marasmus
extreme malnutrition and emaciation. starvation.
Vitamins can be destroyed by
Heat, light. Air
Antioxidant function
Delay or prevent breakdown of cell membrane in presence of O
Pre vitamin form of Beta Carotene
Antioxidants
Vitamin E and C
Antioxidants: Oil?
Usually.
Oils prevent rust in iron
Water soluble vitamins
B, C (wound healing)
Not stored in body, excess excreted in urine
Fat soluble vitamins
A, D, E, K
Over consumption leads to toxicity
Stored in liver and fat
Bothe vitamins and minerals can be lost in food by…
Cooking in water
Minerals can be destroyed by..
Nothing.
They are single elements, not compounds
Vit C for?
Deficiency?
- wound healing, immune function
- deficiency: Scurvy
- Symptoms: petichea, gum disease, lose teeth and hair
Vit D for?
Deficiency?
Found in milk, dairy
Body can make it w exposure to sun
Deficiency: Rickets (osteopenia, osteomalaysia
