The MaCROS & MiCROS


Just some...Nutrition Basics:
Functions of Nutrients:         1.Provide energy
                                                2. Build and repair tissue
                                                3. regulate metabolic processes

Metabolism- sum of all body processes that accomplish the body (measure speed in calories)

Kilocalorie- 1,000 little calories—amount of energy(heat) needed to raise 1L of h2o 1 degree Celsius

Principle of Nutrient interaction    1. No nutrient works perfectly alone
                                                            2. Nutrients have multiple roles

MaCRO Nutrients (3)ONLY nutrients that PROVIDE energy
         
          *CARBOHYDRATES #1 function: energy provider (4 cal/gram)
                        -from plants
                        -saccharides-building blocks
            *Glycogen is the storage form of Carbs

            *FAT Back up energy source (9kcal.g)
                        -fatty acids-building blocks
            *Adipose tissue—storage form of FAT
           
            *PROTEIN back up, back up energy source (4 cal/g)
                        -Amino Acids-building blocks
            *Store protein as MUSCLE

Other 3 = MICRO NUTRIENTS *minerals,vitamins AND h2O*
            Water-controls metabolism

RDA’s: Recommended daily allowance
            PROTEIN 10%-35%
            CARBS 45%-65%
            FAT 20%-35%
EAR: Estimated average requirement
UL: Tolerable Upper intake level
AI: Adequate Intake

Math: For a Food that contains, 24g Carbs, 2g Fat and 10g Protein
Carbs  25g * 4= 100
FAT     2g *9= 18
Protein 10g*4= 40
                        =158 calories total
