Processed meats such as cold cuts, bacon, sausages and hot dogs contain nitrates, chemical additives that preserve freshness. Nitrates have been linked to stomach cancer and other degenerative diseases. These fatty meat products are also full of unhealthy saturated fat that can raise levels of "bad" LDL cholesterol, a risk factor for heart disease and strokes.
Ditch preserved meats altogether or look for ones that are advertised as "nitrate-free." Buy meats low in saturated fats such as chicken and turkey or eat more fish, like salmon or tilapia, rich in healthy omega-3 fats. If you must have red meat, choose lean cuts like sirloin or tenderloin.
