Low metabolic rate/cold intolerance
characteristics of bulimia nervosa (5)
- repeated binge eating (either eating a large amount in a short amount of time or experiencing a loss of control over eating during binges)
- repeated unsafe means of preventing weight gain
- binge occurs at least time per week for 3 months
- undue influence of body weight or shape on self-evaluation
- behaviors purging/binging (DISTINCT)
health consequences of bulimia nervosa
Swollen salivary glands
Irritation of the esophagus
Stomach ulcers
Dental decay
Iron deficiency
Blood potassium imbalance
Irregular heart decay
Constipation
Sleep disturbances
Immune dysfunction
infertility
characteristics of binge eating disorder (3)
- recurring binge eating associated w three of the following:
- a rapid rate of eating
continuing to eat beyond fullness
overeating in the absence of hunger
eating alone
feelings of self-disgust/depression/guilt after - binges occur @ least one time per week for 3 months

health consequences of binge eating disorder
Hypertension
High cholesterol
Osteoarthritis
Fatty liver disease
Atherosclerosis
Type 2 diabetes
Some types of cancer
Sleep apnea
Sleep disturbances immune dysfunction

Troublesome foods
foods that are moist and rich in protein
how can microbial food poisoning be prevented
- clean
- chill
- separate
- cook
temperature danger zone
40-140 degrees F, where bacteria grows quickly
safe temp for the fridge
below 40, optimal is 35
safe temp for the freezer
below 32, optimal is 0 F
cooking fish/beef/pork
145 degrees F
cooking all poultry
165 degrees F
cooking ground meats/eggs
160 degrees F
three food preservation techniques
pasteurization, ultra-high temperature treatment, irradiation
pasteurization
processing te food at high heat, killing some bacteria, the goal is to kill pathogenic bacteria
ultra-high heat treatment
high temperature for a short amount of time to kill bacteria
irradiation
food is exposed to doses of ionizing energy or radiation, extending the shelf life
long term health complications of environmental contaminants in food
** 1/1000 or 1/100 of the dose found to cause no adverse health effect is allowed by the EPA
less than 1% of domestic and 3% of important foods have residues over tolerance, therefore the risks are very low
Pros of GMOs
- change the nutrient content
- extend shelf life
- resistant to pests or insects
- more hardy
- lower production costs
Cons of GMOs
- nutrition composition
- accidental drug ingestion
- GE pesticide resistance
- speculation about the development of allergies, resistance to antibiotics, and synthesis of toxic substances
Pros of organic foods
- more environmentally friendly
- may taste better or be fresher
- higher phenolic may be higher
