What are nitrates and why it is beneficial?
Nitrates is a netric salt that present naturally in many fruits, vegetables and grains, it is also used in cured meats like salami, bacon and hot dogs to preserve color and inhibit the growth of microorganisms, foods that are naturally rich in nitrates can provide valuable health benefits to the body,
What level of nitrates is dangerous?
Some laboratories test forages for nitrate ion (NO3) and report parts per million nitrate. In general the guidelines will suggest that forages that contain greater than 10,000 ppm will be potentially lethal. Forages that contain between 2,000 and 10,000 parts per 1 million may affect milk production and may cause abortion.
Why are foods with nitrites harmful?
“When you eat nitrates, they are converted to nitrites by bacteria in your mouth. Once the nitrites reach the stomach’s acid, they can turn into either nitric oxide [NO] or N-nitroso compounds. N-nitroso compounds like nitrosamines are carcinogenic.
Is nitrate harmful to humans?
You cannot taste, smell, or see nitrate in water. Consuming too much nitrate can be harmful—especially for babies. Consuming too much nitrate can affect how blood carries oxygen and can cause methemoglobinemia (also known as blue baby syndrome).
Why are nitrites unhealthy?
When the nitrites manufactured in our mouth are swallowed, one of the things that can happen is that they react in the strongly acidic environment of the stomach to form nitrosamines – some of which are carcinogenic and have been linked with bowel cancer.
Are nitrites harmful?
Nitrites (NO2) consist of one nitrogen atom and two oxygen atoms. Nitrates are relatively inert, which means they're stable and unlikely to change and cause harm. However, bacteria in the mouth or enzymes in the body can convert them into nitrites, and these may be harmful.
Which is worse nitrates or nitrites?
Nitrate is less toxic than nitrite and is used as a food source by live plants. The process of converting ammonia to nitrate is diagramed in the nitrogen cycle.
Are nitrites carcinogenic?
Nitrates and nitrites are not themselves carcinogenic; nevertheless, they have the potential (during the endogenous pathway as well as processing of food) to react with other compounds to form carcinogens.
Are nitrites in bacon bad for you?

Cured deli meats on average have up to 500 mcg of nitrates per 100 g of meat, while uncured deli meats have about 300 mcg in the same amount of meat.
What do nitrates do to your body?
Nitrate performs physiological functions in various systemic activities, including blood pressure reduction, platelet aggregation inhibition, and vessel protective effect - functions similar to those of NO [3, 37].
Why are nitrates added to food?
Nitrates (or nitrites) are natural chemicals that are found in the soil, air and water. Nitrates are also used as a food additive to stop the growth of bacteria and to enhance the flavour and colour of foods.
Is ham without nitrates good for you?
And though avoiding nitrates and nitrites is a good idea—they're probable carcinogens, according to the World Health Organization—choosing “no nitrite” (also labeled uncured) meats isn't better.

Do nitrates cause inflammation?
Recent animal and human studies have shown that dietary nitrate and nitrite also modulate inflammatory processes and immune cell function and phenotypes. Chronic low-grade inflammation and immune dysfunction play a critical role in cardiovascular disease.

What happens when you swallow nitrites?
When the nitrites manufactured in our mouth are swallowed, one of the things that can happen is that they react in the strongly acidic environment of the stomach to form nitrosamines – some of which are carcinogenic and have been linked with bowel cancer.

How are nitrites converted?
Most of the nitrites we encounter aren’t consumed directly, but are converted from nitrates by the action of bacteria found in our mouth. Interestingly, research shows that use of an anti-bacterial mouth wash can massively cut down this oral manufacture of nitrites.
What are the two compounds that contain nitrogen and oxygen?
Nitrates and nitrites, such as potassium nitrate and sodium nitrite , are naturally occurring chemical compounds which contain nitrogen and oxygen. In nitrates the nitrogen is bonded with three oxygen atoms, while in nitri tes the nitrogen is bonded with two oxygen atoms. Both are legal preservatives which suppress harmful bacteria in bacon, ham, ...

Is nitrate metabolized in the gut?
Unless conditions exist for reducing nitrate to nitrite in the gut (i.e., high pH and proper intestinal microbial flora), ingested nitrate (NO 3 -) is metabolized and excreted without producing apparent adverse effects. Nitrate in the diet may even enhance host defenses against gastrointestinal pathogens by modulating platelet ...
Can nitrates cause cancer?
2005; Tricker and Preussmann 1991]. Nitrates can react with amino acids to form nitrosamines, which have been reported to cause cancer in animals [Bruning-Fann and Kaneene 1993].

Is processed meat dangerous?
(Keep in mind the IARC’s classifications of carcinogens are based on strength of evidence, not degree of risk, so this does not mean processed meats are as hazardous as smoking and asbestos exposure. It simply means the strength of the evidence is the same.)
Is nitric oxide a free radical?
The Benefits of Nitric Oxide. NO is a soluble gas, and while it’s a free radical, it’s also an important biological signaling molecule that supports normal endothelial function and protects your mitochondria — the little “power stations” in your cells that produce a majority of your body’s energy in the form of ATP.
