oRecreational activ
Change from outdoor tech
oChange in work type
Frm active to + office
oTransportation
Walking cars
oFood
Change in food processing
Sugar & fats are more prevalent

Chem used in food
Maybe an 'obeisogen'
oTaste enhancers like lasagna @ home > healthy than
boxed
Some notes on obesity
- Obesity is not health danger unless disabling
- Obesity related to but not necessarily result of unhealthy lifestyle
oThing pps might be unhealthy (less nutrients & exercise)

King Corn
- Rise in obesity in NY is perhaps related to high fructose corn syrup
- Processing degraded nutrit value despite high productivity
- Almost all corn is converted to corn syrup
oIowa corn has been bred for productivity (i.e. high quality starch production)
oSacrifice nutrit value for productivity (conseq of much processing)
- Corn originates from Mexico = high protein value; Iowa = high productivity (starch)
- Lot of c.syrup ends in soda product
