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?
