Macronutrients (Carbohydrates, Protein, Fats→ Biomolecules)







Macronutrients- nutrition needed in larger amts. (usually grams)
Carbohydrates: 1 carb= 4 calories.
  • Carbon + Hydrogen + Oxygen
  • Produces Insulin (sugar)
  • Supplies us with energy for cells, tissue & organs


Starches include: (Pasta, Bread, Wheat, Rice)
  • Approximately 50-60% of your calorie source comes from here!

 Sugars:
  • Simple sugars: Natural and Refine sugars (commonly found in fruits and milk)
  • Made from very few molecules, so digested very fast
  • Give you long term energy to function
  • Brown Sugar, Honey, Soft Drinks, Syrup etc.


    • Complex Sugars  or Fiber
    • - Mainly plant sources (vegetables), fruits, nuts, whole grains
      - Reduces and ebbs cholesterol levels
      - Indigestible; Intestines push your waste out faster
      - Rate of sugar intake moving throughout body is slowed down 
      - Keeps you lively and feel good about yourself
    • Approximately 25-30% grams of your meals should be/come from fiber









Protein: 1 gram=4 calories
Monomer: Amino Acid; Polymer: polypeptides
  • Animal Meat, Fish, Eggs, Milk, Vegetables: soybeans, nuts, legumes, butter etc.
    • Made from Amino Acids, 20 different types
    • Help to repair cells, produce enzymes, antibodies, hormones
    • Pro: Faster recoveries after exercise, healthy weight, curbs hunger=lean muscle
    • Animal meat supplies us with "actual" proteins with essential amino acids
    • While Non-animal products miss an amino acid but they are still super healthy for you









Lipids or Fats
1 gram=9 calories 
  • Hydrophobic:
               - Provides warmth and stored for long term energy

       Some Cholesterol isn't "all that bad" we have/need some for our bodies to function.  
     However too much or the wrong cholesterol (ex: LDL Cholesterol) isn't good for you, which may lead to problems in the future (ex: Heart attack or stroke).

Unhealthy Fats
  • Saturated Fats:
    • Solid Fat (Animal Meat, Dairy, Tropical Oils, Margarine)
    • Cholesterol Level Raises
    • Low Density Lipoprotein (LDL) or Bad Cholesterol 
    • Clogs up passageways for blood/oxygen to flow through body=Heart Disease
    Trans Fat- Goes through a process known as HYDROGENATION ø
  • Hydrogenation allows food to have longer shelf life and Fat turns hard at Room Temperature (with that, body struggles to metabolize the fat)
    • Trans Fat Increase the chance of High Blood Pressure and Heart Disease
    • ex: Chips, Cookies, Process Food Loaves Donut Holes                                                 
    • NOT GOOD FOR HEALTH

Unsaturated Fat (healthy fats)

• Monounsaturated- Lower Blood Pressure (nuts, olive oils/peanut, avocados and veggies)
• Polyunsaturated: (Mainly oils of safflower, sunflower, sesame and soybean, corn)
• High Density Lipoprotein (HDL) or Good Cholesterol
         - Scavenges for any 'bad fat' and helps removes it from bloodstream
         - Reduces your chance of heart disease 

OMEGA 3 fatty acids: Plants (vegetables/seeds), Fish and (EPA and DHA)
- Eat them about twice a week, the more the better

OMEGA 6 fatty acids: Veggie Oils

Benefits-
- Lower your blood level
- Chance of ADHD
- Asthma
- Dpression
- Reduce chance of Birth problems
