#4 Canned Foods
Canned foods: There are many reports nowadays suggesting that canned foods that come from the orient may be full of contaminants (eg bisphenol-A). Canned sardines and other canned products from Se Asia have been found to contain high levels of metals and other harmful bacteria.
Just take a look at the pollution in the waters in Asia and you will see why. Best advice; buy and eat fresh foods.
