It was very rare that we ate any form of chicken or turkey. The same for fish even though I was living in San Francisco.
There has been a radical change in America's eating habits.
Today, the most common food on the table is chicken. Almost any other meat is less common and beef has become a rarity for many. (There is a current resurgence of hamberger and steak restaurants.) Turkey is also very common but I am not a fan.
This redemption of chicken has not occurred because of fat, cholesterol and heart attacks. This redemption of chicken has not occurred in the Midwest where beef and pork are still dominant on everyday tables.
Chicken has grown to its central role on the coasts because the chicken has grown significantly larger and cheaper. Thanks to the of genius technology in animal husbandry.
Just pointing it out. Commerce is always disruptive.
