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
