Carbohydrates, Fats, Proteins

Complex carbohydrates & sugars   Naturally found in fruits (rare), cereal grains, beans   Usually in conjunction with fiber   Slows down digestion  

Refined carbs & sugar   No fiber, minerals, vitamins 1.  Quickly converted into blood glucose 2.  Blood glucose low again in couple hours 3.  Still insulin – no fat matabolized 4.  Eat again 5.  Heart attack & diabetes  

   

Lipids are necessary Essential fatty acids ◦  ◦  ◦  ◦ 

 

Polyunsaturated Fats the body cannot synthesize Omega6 – plant oils Omega3 – fish

Butter & animal fats are saturated

◦  Liquid at room temp = good ◦  Solid at room temp = worse

   

Cholesterol = necessary, but too much  heart disease & stroke Trans-fats: from hydrogenation ◦  Lipase cannot process

Amino acids – 20   Eight are essential   Animal proteins match human needs   Plant proteins usually lack some essentials  

◦  Quinoa  

Beans and rice: ✓

 

Carbohydrates – none ◦  Supplemental pathways

 

Fats – rabbit starvation (if protein high) ◦  Diarrhea, discomfort, fatigue, low blood pressure, hunger

 

Protein

◦  Marasmus   Tissue & muscle wasting

◦  Kwashiorkor   Edema, anorexia, skin ulcers   Protein deficiency + other nutrients

 

Vitamins ◦  Organic molecules essential for growth & survival ◦  Must obtain from diet ◦  Micro amounts

 

Minerals ◦  Inorganic substances

 

Supplements? ◦  Regular consumption of veggies & whole foods ◦  Vegetarians (D & B12), sick, elderly, pregnant ◦  Too much?
