Key Concepts: Key Concepts: Nutrients: Energy, building blocks,

vitamins and minerals, waterSpecial Nutrients: Antioxidants,

Fiber, SupplementsFood Guide Pyramid:

Recommendations for HealthFood Mythology: What’s true,

what’s not?

Energy NutrientsEnergy NutrientsCarbohydrates: Primary source

of energy for living, healing and growing

Fats: Highest energy “density” (calories/gram)

Proteins: Provides energy, but “at a cost” – the real value of proteins is in the “BUILDING BLOCKS”

Page 10: Horace Pippin: (

Energy Needs:Energy Needs:Living: Maintaining all normal body

functions and activitiesGrowing: You want a new muscle? Healing: Tissue repair, immune system

functionEnergy Units: : Calories (Kcals = heat

required to raise 1kg water by 1 degree C)

Energy Efficiency: : About 20%!

Page 11: Horace Pippin: (

Carbohydrates: Carbohydrates: Simple Sugars:

Sugar, Fruit sugar, honey, milk sugar

Complex Carbohydrates:Breads, pasta,

beans, potatoes, rice, starchy vegetables

Page 12: Horace Pippin: (

Fats: Fats: Energy Dense: 9cals/gram (twice the calories/wt as carbs or proteins

Types:SaturatedPolyunsaturatedMonounsaturatedCholesterol

Page 13: Horace Pippin: (

Saturated vs UnsaturatedSaturated vs Unsaturated

“Full” of Hydrogen

Solid at room temp

Mostly from animals

Associated with cholesterol

“Not Full” of Hydrogen

Liquid at room temp (OIL)

Mostly from plants

May reduce cholesterol

Page 14: Horace Pippin: (

Fats and Heart DiseaseFats and Heart DiseaseDiets high in Saturated Fats are

associated with high LDL cholesterolDiets high in Unsaturated Fats are

associated with low LDL (but also low HDL…)

Diets high in Monounsaturated Monounsaturated FatsFats associated with increased HDL’s! That’s GOOD!

Page 15: Horace Pippin: (

Proteins: Proteins: Provides amino acids building proteins

8-9 Essential amino acids

Muscles, blood, organs, skin, hair, nails, immune system

Page 16: Horace Pippin: (

But a “costly” energy…But a “costly” energy…Protein has ~4 kcals/gramTo release this energy, the protein

must be broken downNitrogen by-products are toxicKidneys + Water loss involved can

handle only so much…So WHAT ABOUT HIGH PROTEIN

DIETS?

Vitamins and MineralsVitamins and MineralsMicronutrients: Non-caloricEssential for HealthVitamins: Organic (carbon molecules)

Water-soluble: B and CFat-soluble: A,D,K, E

Minerals: Inorganic elements Iron, CalciumSodium

Water: The “Forgotten Water: The “Forgotten Nutrient”Nutrient”

60-70% the stuff we’re made of

Lubrication, mucous, temperature regulation, metabolism

Thirst and HydrationThirst and Hydration“Thirst” lags behind dehydrationDehydration:

Reduction of physical performance

Reduction of mental performanceWhat about singing?!?Headaches, infections, healing

Page 20: Horace Pippin: (

Special Nutrients: Special Nutrients: Antioxidants:

Vitamins C and E and Beta-carotene

Reduces oxidation of LDL

Reduces CVD Risk

Red Hot Chili Peppers

Page 21: Horace Pippin: (

Fiber:Fiber: Un-digestible complex carbohydrate

Improves digestion

Reduces risk of CVD, Diabetes, GI and breast cancers, obesity

Fruits, vegetables, Whole grains, rice,Legumes, oatmealCereals …
