While gastric cancer is declining, it is still the most common cancer in Korea. Past studies have yielded conflicting results as to whether a salty diet causes gastric cancer, though most found an association between salt use and gastric cancer.
Here's another piece of information: https://en.wikipedia.org/wiki/Refrigerator
The introduction of Freon in the 1920s expanded the refrigerator market during the 1930s. Home freezers as separate compartments (larger than necessary just for ice cubes) were introduced in 1940.

Perhaps he means inflammation. Inflammation has been linked to certain types of cancers.
yes, I meant that, and no - nearly all cancers are linked to inflammation. the differences are in what causes the inflammation.

I found a chart showing the prevalence of multiple forms of cancer over time: http://i52.tinypic.com/r9euci.jpg .
Weird. Why would lung cancer go the opposite direction as smoking prevalence? I understand the dynamic of "cancer only kills people who outlive every other cause of death", but for the discorrelation to be that strong?

Type II. Type II is insulin resistance. Which is probably caused by our industrial diet and maybe other factors. The rate is increasing dramatically. Type I is an autoimmune disease. I think it's not increasing. (no idea)
its less caused by diet than lack of mobility. we spend most of our waking day sitting down now. active over weight people with 'bad diets' are healthier than skinny inactive people. but its hard to legislate that, and much easier to pound the shoe on the table about sodas than it is to tell people they need to get up and move
