Not the answer you expected eh?
But...... 100g of trimmed, cooked lean pork contains - 36% of your RDA of zinc; 38% of vitamin B12; 65% Vitamin B1 (thiamin); 47% vitamin B3 (niacin)............and other benefits like essential minerals - iron, magnesium and phosphourous etc, more benefical vitmains and an amount of necessary fat to allow the body to function.
Eat chicken?..... How reared, what conditions, what amounts of bactericides and growth promoters pumped into the flesh? Imported to UK from Brazil or Thailand? Animal sufered from hock burns and cramped living conditions in inhumane methods of treatment?
Eat lamb?......British and grass reared or again an imported product that has no provenance, has suffered in transporting to slaughter and can not be assured for quality ?- and in any case can be a lot more fatty than pork through the nature of the meat.
Eat beef?..... is it grass fed and UK produced or eastern european brough to the UK kept here 90 days and then stamped with a UK label as that complies to making it a UK product under the current labelling rules? How has the animal been treated? What growth hormones does the meat contain in terms of residue that gets into our digestive systems? Is it a supemarket roast that is so tasteless that they wrap pork fat round the joint so it can cook?.......
The best diet is a varied - meat, fish, veg, fruit, pulses, grain - seasonal and fresh one that respects the provenance of the ingredients - e.g. why buy Morroccan onions when we grow them in the UK anyway - all it does is give profit to the multi-nationals....or tasteless strawberries in february from Spain - just wait til the summer and buy British.....
Recipe idea for a nice bit of pork after the rant..........
