This is the breakfast I eat every morning (although I have cut out the tomatoes recently). Click onto the photo to go through to the Flickr page and read the labels on each food. Even though I know that a cooked breakfast is the best thing I can be eating in the morning, I really do worry about the nitrates in the bacon (and sausages, which I sometimes eat). But I know the bacon is good for me, so I continue to eat it regardless of all the bad things I have read about nitrate consumption and cancer. It is hand cured with saltpetre (which is potassium nitrate – the natural form of nitrate, which was used until sodium nitrate replaced saltpetre in 1925) and tastes absolutely wonderful, I buy it from the market every week and eat a slice of it every morning.
Recently though, I read a really detailed post about nitrates and their link to cancer, called “Does banning hotdogs and bacon make sense?’ and I was very surprised to learn that:
In 1981, the National Academy of Sciences reviewed the scientific literature and found no link between nitrates or nitrites and human cancers, or evidence to even suggest that they’re carcinogenic. Since then, more than 50 studies and multiple international scientific bodies have investigated a possible link between nitrates and cancers and mortality in humans and found no association.
What may be more surprising to learn is that scientific evidence has been building for years that nitrates are actually good for us, that nitrite is produced by our own body in greater amounts than is eaten in food, and that it has a number of essential biological functions, including in healthy immune and cardiovascular systems. Nitrite is appearing so beneficial, it’s even being studied as potential treatments for health problems such as high blood pressure, heart attacks, sickle cell disease and circulatory problems.
The primary source of nitrites in our diets is vegetables, and to a lesser degree water and other foods. While it’s popularly believed that nitrates and nitrites mostly come from processed meats, they’re actually a very small source of our nitrite intakes, less than 5-10%. And nitrates aren’t present at all in commercially processed meats.
Nitrates occur naturally in vegetables and plants as a result of the nitrogen cycle where nitrogen is fixed by bacteria. Dietary studies around the world have found 70% (in UK) to over 97% (New Zealand) of human consumption of nitrates and nitrites comes from vegetables alone, regardless of organic or conventionally grown. On average, about 93% of the nitrites we get each day comes from the nitrates in vegetables.
While there remains no evidence for nitrite or nitrate carcinogencity, according to the National Research Council, the confusion among consumers may come from hearing cancer concerns raised aboutnitrosamines. As the IPCS-INCHEM notes, the sole cancer suspicion lies in the formation of N-nitroso compounds (NOCs), whether in the stomach or within the food itself, which have been shown carcinogenic in animals when exposed to high levels. Whether these compounds form in humans in normal dietary conditions in large enough amounts to pose a health risk, however, has not been established. In fact, as it turns out, the pH of our gastric juices doesn’t support nitrosamine formation and there are other substances in our body that inhibit their formation, too.
Nitrites and nitrates can combine with natural amines from proteins to form various NOCs. But the concentrations of nitrosamines in bacon and cured meat are at undetectable levels, according to the USDA. And that’s been known to be the case for more than a decade.

So, it seems that I should be less worried about eating my daily bacon than about the amount of vegetables I am consuming. Unfortunately, most people still do not know these nitrate facts, regardless of many studies being published recently. These studies had little or no exposure in the media, as ‘politically correct‘ nutrition still holds us fast in its grip. This PC nutrition warns us about the dangers of saturated fat, over-consumption of red meat and the benefits of eating soy products and vegetable oils. Traditional wisdom tells us otherwise of course, not that many people have the balls to go against what the FDA recommends.
But more evidence is being amassed that reveals the benefits of nitrates/nitrites on the human body and especially, as these study shows, on the teeth:
As researchers at the University of Aberdeen described nearly ten years ago in the British Journal of Nutrition, the oxides of nitrogen, that are formed in the acidic stomach after swallowing salivary nitrites, have antimicrobial action against a wide range of gastrointestinal pathogens, such as —
• Yersinia enterocolitica
• Salmonella enteritidis
• S. typhimurium
• Shigella sonnei
• E. coli O157:H7
• Helicobacter pylori
• Candida albicans
The antibacterial action increases with nitrate concentrations, they found. Gastric pH rises after food is eaten to levels that are not bactericidal against foodborne pathogens unless nitrite is present. So, nitrites appear to have a biological function to help protect us against stomach infections and foodborne illnesses. Dr. Benjamin also noted that cavity-causing bacteria die in high-nitrite environments and suggested that nitrite may play a role in preventing cavities.

As a follower of Nourishing Traditions, I have recently been reading up again about the Paleo/Primal Diet, which, like so many diets nowadays like Atkins, G.A.P.S, Low-Carb, Low G.I, etc. promote high-fat and protein/low-carb consumption, something that Nourishing Traditions has known about from the start. I therefore believe that bacon should be eaten for breakfast, even the stuff that has been preserved with nitrates. Of course, sourcing the best pastured, locally produced, free-range bacon and ham was always a priority for me and I am now happy to say that, whereas before animal welfare would be positioned in second place to nitrate-free meat, now I will be taking a much more liberal view towards the nitrates in my bacon in order that I can make animal welfare the top priority.
