Sodium Nitrate's Impact On Ketogenic Diet Explained

The Ketogenic Diet is a low-carbohydrate method of eating that has been used to overcome obesity and achieve weight loss. It has also been used to reduce seizures in patients with epilepsy. However, people who follow a dirty keto diet may be consuming high levels of sodium nitrate, which is a preservative commonly found in processed meat products such as bacon, deli meat, and jerky. Sodium nitrate has been linked to an increased risk of heart disease, diabetes, and certain cancers. While it is difficult to consume toxic levels of sodium nitrate through natural foods, it is important to be aware of the potential risks associated with excessive consumption. To avoid negative health effects, it is recommended to limit the intake of cured meats and opt for organic, nitrate-free alternatives or try curing bacon at home.

Sodium nitrate is linked to an increased risk of heart disease and diabetes

Sodium nitrate is a preservative commonly added to cured meat products to extend their shelf life, maintain their colour, and enhance their flavour. While sodium nitrate is not inherently bad, excessive consumption has been linked to an increased risk of heart disease and diabetes.

The human body requires nitrates and nitrites, which are naturally derived from vegetables. However, when consumed in high quantities, these compounds can have detrimental effects on health. Sodium nitrate has been associated with the development of heart disease by increasing blood pressure and impairing blood flow. Additionally, it contributes to the formation of nitrosamines, which are carcinogenic compounds found in our environment and certain drugs.

The World Health Organization (WHO) has declared processed meats, which often contain sodium nitrate, as carcinogens. This has sparked a movement towards organic, nitrate-free alternatives. However, it is important to note that these products often use celery powder, which is essentially sodium nitrate derived from a natural source. The amount of nitrate residue in these natural alternatives can be about ten times higher than in traditionally cured products.

To avoid excessive sodium nitrate intake, it is recommended to limit the consumption of cured meats and opt for organic, whole foods. While sodium nitrate itself is not conclusively proven unsafe, the real concern lies with the excessive consumption of processed meats. A well-rounded diet rich in vegetables and whole foods can provide the necessary nitrates and nitrites while also offering nutritional benefits such as healthy carbs and fibre.

It is also associated with certain cancers

Sodium nitrate is a preservative commonly added to cured and processed meat products to extend their shelf life, give them flavour, and make them appear fresh. It is also found in some vegetables and present in unregulated drinking water.

Overconsumption of sodium nitrate is associated with an increased risk of certain cancers. Sodium nitrate is converted into nitrosamines in the body, which are known carcinogens. A study published in the World Journal of Gastroenterology found that sodium nitrate transformed into nitrosamines can cause gastric cancer.

The way nitrates and nitrites are cooked also affects whether they become carcinogenic. When exposed to high temperatures, nitrites can react with proteins in meat to form nitrosamines. This is why nitrates and nitrites from vegetables are not associated with cancer risk, as vegetables do not contain high levels of protein.

The International Agency for Research on Cancer categorises processed meat as a carcinogen, but the risk is relatively small. The World Cancer Research Fund notes that while nitrites in processed meats may contribute to bowel cancer, their relative importance is uncertain.

To avoid the potential dangers of sodium nitrate, it is recommended to limit the consumption of cured and processed meats and opt for a diet rich in organic fruits and vegetables.

The human body needs nitrates and nitrites

Nitrates and nitrites are essential compounds that occur naturally in the human body and some foods. They are also added to certain processed foods to extend shelf life. While they can be hazardous in certain forms, they may offer health benefits in some cases.

Nitrates (NO3) and nitrites (NO2) are two different types of compounds. Nitrates consist of one nitrogen atom and three oxygen atoms, while nitrites consist of one nitrogen atom and two oxygen atoms. Nitrates are relatively inert, which means they are stable and unlikely to change and cause harm. However, bacteria in the mouth or enzymes in the body can convert them into nitrites, which may be harmful.

In the body, nitrites can turn into nitric oxide (NO), a beneficial signaling molecule that causes blood vessels to dilate and reduces blood pressure. Nitric oxide has various functions in the body and can help protect it. It is also a signalling molecule that travels through the artery walls and sends signals to the tiny muscle cells around the arteries, telling them to relax. This leads to a decrease in blood pressure.

Nitrates and nitrites are also important for plant growth and are necessary for plants and animals to grow and be healthy. Vegetables with high levels of nitrates include spinach, radishes, lettuce, celery, carrots, cabbage, and beets. According to studies, people obtain around 80% of their dietary nitrates from vegetables.

While nitrates and nitrites can be beneficial, they can become hazardous if they form nitrosamines. Nitrosamines are carcinogenic compounds that can form when nitrates or nitrites are cooked at high heat, especially in the presence of protein. A high intake of processed meats containing nitrates and nitrites may increase the risk for cancer in the digestive tract. However, cooking vegetables is less likely to produce nitrosamines, as they are not usually cooked at very high heat and do not contain large amounts of protein.

In conclusion, while it is important to be aware of the potential risks associated with nitrates and nitrites, they are essential compounds that offer several health benefits to the human body.

Vegetables are a natural source of sodium nitrate

Nitrogen is turned into sodium nitrate in the soil and is necessary for plant growth. Plants absorb sodium nitrate from the soil in varying amounts. Vegetables with high levels of sodium nitrate include spinach, radishes, lettuce, celery, carrots, cabbage, and beets. According to studies, approximately 80-90% of dietary nitrates in a person's diet come from vegetable consumption.

The nitrates found in vegetables are not harmful because they are coupled with nutrients like vitamin C and antioxidants that prevent them from converting into harmful compounds. Vegetables rich in natural nitrates can help improve heart health and may offer some protection against cancer.

While cured meats may also contain sodium nitrate, it is added as a preservative and to enhance color and flavor. High consumption of cured meats containing sodium nitrate has been linked to an increased risk of cancer and other health issues. Therefore, it is recommended to limit the intake of cured meats and boost the consumption of vegetables, which are a natural and healthy source of sodium nitrate.

Processed meats are the real culprit, not nitrates

Processed meats are often blamed for being unhealthy, with bacon, salami, prosciutto, and pepperoni being the usual suspects. But are these meats really to blame, or is it the nitrates they contain?

Nitrates are a natural part of our diet and are necessary for plant growth. They are found in many vegetables, including spinach, radishes, lettuce, celery, carrots, cabbage, and beets. In fact, according to a 2009 study, approximately 80% of the nitrates in our diet come from vegetable consumption. So, why are nitrates often associated with negative health effects?

The answer lies in the processing of meat. When meat is cured, sodium nitrate and sodium nitrite are added to inhibit bacteria and moulds from forming during the curing process, and to give the meat a distinct flavour, colour, and longer shelf life. While these nitrates and nitrites are not inherently bad, they can form carcinogens called nitrosamines when heated at high temperatures. This is why processed meats, which often contain nitrates, have been linked to an increased risk of cancer, heart disease, and diabetes.

However, it's important to note that the human body also needs nitrates and nitrites. These compounds are converted into nitric oxide, which has several health benefits, including protecting against cardiovascular disease, lowering blood pressure, and improving blood flow. So, the real issue is not the presence of nitrates but the formation of nitrosamines during the processing and cooking of meat.

To avoid the negative effects of nitrosamines, it's recommended to limit your consumption of cured and processed meats, and instead get your nitrates from vegetables. This way, you still benefit from the essential compounds that nitrates provide, without the harmful effects of nitrosamines. Additionally, eating organic foods can help reduce nitrate intake, as organic foods are not grown with synthetic nitrogen fertilizers, which increase nitrate content.

So, the next time you're tempted by a bacon sandwich, remember that it's not the nitrates you need to worry about, but the processing methods and cooking techniques that can turn these essential compounds into something more harmful.
