What foods do you guys know of that aren't as good as they used to be?
Here's the ones I know.

1. Salmon. They have farm raised salmon which is inferior to
wild-caught salmon because the farm salmon lacks omega 3 fatty acids,
which are important for many human physiological functions, including
the creation of more serotonin, which helps fight depression.

2. Coffee. I heard that the average coffee is lower quality than it
used to be, because at some time, maybe in the 70's, there was a coffee
shortage, which resulted in lower coffee quality. And ever since then,
Americans have become accustomed to drinking lower quality coffee.
(However, I'm sure high quality coffee is still available if you look
for it)

3. Meat - Americans used to eat a lot of wild meat 100 or more years
ago. Once again, it had omega 3 fatty acids, which farm raised meats
lack. (By the way, I take fish oil pills which have the omega 3 acids).
