Basic Definitions:
Nutrients—consumables that perform a function in the human body
Calories—units of measurement of energy
- Macro-Caloric Nutrients (Large with Calories)
- Proteins (4 calories/gram)–Made up of amino acids (AA’s); there are 20 amino acids; 9 are Essential Amino Acids (EAA’s); 11 are Endogenously created (they are made from ingredients in the body)
- Complete Proteins—have all 9EAA’s (or all 20 AA’s)
- Sources of Complete Proteins Enzymes that break Proteins down to AA’s
- Meat pepsin—breaks long chains into short
- Eggs trypsin—breaks short chains into AA’s
- Dairy
- Sources of Complete Proteins Enzymes that break Proteins down to AA’s
- Incomplete Proteins—DO NOT have all 9 EAA’s
- Complementary Proteins–2+ Incomplete Proteins that together have all 9 EAA’s, creating a Complete Protein
- Complete Proteins—have all 9EAA’s (or all 20 AA’s)
- Carbohydrates (4 calories/gram)—the preferred fuel of the body
- Simple Carbs
- Monosaccharides
- Glucose
- Fructose
- Galactose
- Disaccharides Enzyme that breaks it down
- Maltose = glucose + glucose Maltase
- Sucrose = glucose + fructose Sucrase
- Lactose = glucose + galactose Lactase
- Monosaccharides
- Complex Carbs
- Fiber (2 calories/gram)
- Soluble
- Insoluble
- Polysaccharides (Starch, etc.)
- Fiber (2 calories/gram)
- Simple Carbs
- Fats (Lipids)(9 calories/gram)—heat, & cushioning
- Saturated
- Unsaturated
- Mono-Unsaturated Fatty Acids (MUFA’s)
- Poly-Unsaturated Fatty Acids (PUFA’s)
- Omega 3’s
- Omega 6’s
- Other (for our purposes)
- Triglycerides
- Cholesterol
- HDL’s (High Density Lipoproteins)—‘good cholesterol’
- LDL’s (Low Density Lipoproteins)—‘bad cholesterol’
- Trans Fats (Hydrogenated Fats)—result of high heat applied to PUFA’s & used to extend shelf life of foods.
- Proteins (4 calories/gram)–Made up of amino acids (AA’s); there are 20 amino acids; 9 are Essential Amino Acids (EAA’s); 11 are Endogenously created (they are made from ingredients in the body)
- Macro-Non-Caloric Nutrient (Large, No Calories)
- Water
- Micro-Non-Caloric Nutrients (Small, No Calories)
- Vitamins
- Fat Soluble
- Vitamin D—helps uptake calcium
- Vitamin E—potent antioxidant
- Vitamin K—helps in blood clotting
- Vitamin A–
- Water Soluble
- Vitamins B1, B2, B3, B6, B12—various energy uptake and production functions
- Vitamin C—antioxidant and bone health
- Biotin–
- Choline
- Folate
- Pantothenic acid
- Fat Soluble
- Minerals
- Metals
- Na, Mg, K, Ca
- Non-Metals
- F, P, Cl, Se, I
- Transition Metals
- Cr, Mn, Fe, Cu, Zn, Mo
- Metals
- PhytoChemicals
- Just remember anticancer for now. We’ll go into details later. They give fruits and vegetables their color.
- Vitamins
