General Nutrition Information Carbohydrates
Increase tryptophan which leads to serotonin causing relaxation, sleep and lower sensitivity to pain
Protein Concentration and alertness
High sugar Tooth decay Osteoporosis Cancer Diabetes High blood pressure Heart disease Mainly because high sugar items are eaten
instead of healthy ones! Too much salt + low calcium = high blood
pressure Breakfast = more alert and less fatigue “good fat” aka omega-3 fatty acid (fish)
Enhanced brain function Less depression

Fat cells Shrink, but never go away Take less energy to maintain
Set points and metabolism Body fights to keep itself at the same weight People can loose at first, then the body lowers

another
