If there is one food that has been proven time and again to be really unhealthy and linked with disease, its processed meat. The worst offender, in terms of ingredients, are the nitrites, which increase the risk of colon cancer. This is why I only buy veggie dogs for my hot dog loving girls, because even though they too are processed, they at least don't contain nitrites.
Nitrites are not only added to hot dogs, but often to smoked meats and deli meats. Its pretty tough to find these products without, even if they are organic, local, blah, blah, blah.
That's why I love McLean's products. I've raved about their turkey bacon before, and I have also bought their kielbasa a few times. Then I discovered they make a nitrite-free turkey jerky! I am big on protein snacks because I find they are more satisfying. I bought a few packs for Adam for Passover, because they are also wheat/gluten-free and soy-free. Finally a company that gets it...and it just happens to be a family-owned, Canadian business. I'll gobble to that!!
