Kippered snacks are good , sardines and yellow mustard
Did you ever wonder why it’s called omega oil ? It is named after the omega fishing company , they at one time , back in the 1940s (?) harvested a lot of small oily fish like sprat . The fish were valued for being processed into industrial lubricants , not as food .
More , at one time fish oil was also processed into margarine , but it fell out of favor after tropical , palm oils made it into the market and were much cheaper .
Of course , based upon what we know now , people are scrambling to get rid of tropical oils and back to natural fish oils.
