I can’t recall exactly why luncheon meat is unhealthy food but it has been my belief since I started teaching.
Like any protein of animal origin, you can be certain that saturated fats and cholesterol are present in luncheon meats too. These are artery clogging fats which one should know better to avoid.
My parents have been using luncheon meats as side dishes for our meals as long as I can remember. It is really tasty on its own or with bread or even rice. There were rumours that luncheon meats produced in China contained rat meat. We have heard and read enough news about the unthinkable things that go into processed foods ‘made in China’.
But I couldn’t resist the temptation when Yang presented those lightly fried sliced luncheon meats together to go with the sweet potato porridge. They go well with the porridge. Now, after blogging about the horror one may uncover in those meats, I’m once again convinced not to touch those meats again! 
oh i think it’s bad because the ingredient is PIG. yes, i mean every single part of the animal including snout, testicle, penis, gut, bladder… they just grind up all those left-over chapalang bits after the meaty parts have been selected for sale and ta dah! you get luncheon meat…. i never really touch luncheon meat… gosh, the trans fat and toxins…. but before i heard about this i did find it quite delicious… kekeke ^^
Haha.:) Now that will for sure put Ling off luncheon meat, permanently. :)
