How bad is Processed Meat: Processed meat is typically thought of unhealthy.

It has been linked with diseases like most cancers and heart disease in quite a few research.

There is little doubt that processed meat contains many dangerous chemicals that aren’t current in fresh meat.

This article takes an in depth take a look at the health results of processed meat.

What is Processed Meat? (How bad is Processed Meat)

Processed meat is meat that has been preserved by curing, salting, smoking, drying or canning.

Food products categorized as processed meat include:

  • Sausages, hot dogs, salami.
  • Ham, cured bacon.
  • Salted and cured meat, corned beef.
  • Smoked meat.
  • Dried meat, beef jerky.
  • Canned meat.

On the opposite hand, meat that has been frozen or undergone mechanical processing like reducing and slicing is still thought of unprocessed.


All meat that has been smoked, salted, cured, dried or canned is thought of processed. This consists of sausages, hot dogs, salami, ham and cured bacon.

Eating Processed Meat is Associated with an Unhealthy Lifestyle

Processed meat has constantly been linked with dangerous results on health.

This is a indisputable fact that health-conscious people have been conscious of for many years.

For this motive, eating excessive quantities of processed meat is extra widespread amongst people with unhealthy life-style habits.

As an instance, smoking is extra widespread amongst those that eat tons of processed meat. Their intake of fruit and vegetables is also much lower (1Trusted Source2Trusted Source).

It is doable that the links discovered between processed meat and disease are partly as a result of people who eat processed meat are inclined to do different issues that aren’t related to good health.

Most observational research on processed meat and health outcomes attempt to appropriate for these factors.

Nevertheless, research constantly discover strong links between processed meat consumption and numerous persistent diseases.


People who are usually not health-conscious are inclined to eat extra processed meat. This could partly clarify some of the associations discovered in research investigating processed meat consumption and disease.

Processed Meat is Linked with Chronic Disease

Eating processed meat is related to increased danger of many persistent diseases.These include:

Studies on processed meat consumption in people are all observational in nature.

They present that people who eat processed meat are extra probably to get these diseases, but they cannot show that the processed meat brought about them.

Even so, the proof is convincing as a result of the links are strong and constant.

Additionally, all of this is supported by research in animals. For instance, research in rats present that eating processed meat raises the chance of bowel most cancers (15Trusted Source).

One factor is clear, processed meat contains dangerous chemical compounds that will increase the chance of persistent disease. The most generally studied compounds are mentioned right here below.


Eating excessive quantities of processed meat over a protracted interval could increase the chance of many persistent diseases, such as heart disease and most cancers.

Nitrite, N-Nitroso Compounds and Nitrosamines

N-nitroso compounds are cancer-causing substances believed to be chargeable for some of the antagonistic results of processed meat consumption.They are fashioned from nitrite (sodium nitrite) that is added to processed meat products.

Sodium nitrite is used as an additive for 3 causes:

  1. To protect the red/pink colour of meat.
  2. To improve taste by suppressing fats oxidation (rancidification).
  3. To stop the growth of bacteria, improving taste and reducing the chance of meals poisoning.

Nitrite and related compounds, such as nitrate, are additionally discovered in different foods. For instance, nitrate is discovered in comparatively excessive levels in some vegetables and could even be useful for health (16Trusted Source).

However, not all nitrite is the identical. Nitrite in processed meat can flip into dangerous N-nitroso compounds, probably the most extensively studied of that are nitrosamines (17Trusted Source).

Processed meat is the principle dietary supply of nitrosamines (18Trusted Source). Other sources include contaminated ingesting water, tobacco smoke, and salted and pickled foods (17Trusted Source19Trusted Source).

Nitrosamines are primarily formed when processed meat products are uncovered to high heat (above 266°F or 130°C), such as when frying bacon or grilling sausages (20Trusted Source).

Studies in animals point out that nitrosamines could play a serious role in the formation of bowel most cancers (15Trusted Source21Trusted Source).

This is supported by observational research in people, indicating that nitrosamines could increase the chance of abdomen and bowel most cancers (22Trusted Source23Trusted Source).


Processed meat that is fried or grilled could include comparatively excessive levels of nitrosamines. Studies recommend that these compounds could increase the chance of most cancers in the stomach and bowel.

Polycyclic Aromatic Hydrocarbons (PAHs)

Meat smoking is one of the oldest preservation strategies, usually used in mixture with salting or drying.

It results in the formation of numerous probably dangerous substances. These include polycyclic fragrant hydrocarbons (PAHs) (24).

PAHs are a large class of substances that type when natural matter burns.

They are transferred into the air with smoke and accumulate on the floor of smoked meat products and meat that is barbecued, grilled or roasted over an open hearth (25Trusted Source26Trusted Source).

They might be formed from:

  • Burning wooden or charcoal.
  • Dripping fats that burns on a hot floor.
  • Burnt or charred meat.

For this motive, smoked meat products might be excessive in PAHs (2725Trusted Source).

It is believed that PAHs could contribute to some of the adverse health results of processed meat.

Numerous research in animals have proven that some PAHs could cause most cancers (2428Trusted Source).


Smoked meat products could include excessive quantities of polycyclic fragrant hydrocarbons (PAHs). These compounds have been proven to trigger most cancers in animals.

Heterocyclic Amines (HCAs)

Heterocyclic amines (HCAs) are a category of chemical compounds that type when meat or fish is cooked under excessive temperature, such as throughout frying or grilling (29Trusted Source30Trusted Source).They are usually not restricted to processed meat, but vital quantities might be discovered in sausages, fried bacon and meat burgers (31Trusted Source


HCAs trigger most cancers when given to animals in excessive quantities. Generally talking, these quantities are much greater than these usually discovered in the human diet (32Trusted Source).

Nevertheless, quite a few observational research in people point out that eating well-done meat could increase the chance of most cancers in the colon, breast and prostate (33Trusted Source34Trusted Source35Trusted Source).

The level of HCAs might be minimized by utilizing gentle cooking strategies, such as frying under low heat and steaming. Avoid eating charred, blackened meat.


Some processed meat products could include heterocyclic amines (HCAs), carcinogenic compounds additionally discovered in well-done meat and fish.

Sodium Chloride

Processed meat products are normally excessive in sodium chloride, also called desk salt.

For 1000’s of years, salt has been added to meals products as a preservative. However, it is most frequently used to improve style.

Although processed meat is removed from being the one meals that is excessive in salt, it might contribute considerably to the salt intake of many people.

Excessive salt consumption could play a role in hypertension and heart disease, particularly in those that have a situation known as salt-sensitive hypertension (36Trusted Source37Trusted Source38Trusted Source39Trusted Source40Trusted Source).

In addition, a number of observational research point out that diets excessive in salt could increase the chance of abdomen most cancers (41Trusted Source42Trusted Source43Trusted Source44Trusted Source45Trusted Source).

This is supported by research displaying {that a} high-salt diet could increase the expansion of Helicobacter pylori, a bacterium that causes abdomen ulcers, that are an vital danger issue for abdomen most cancers (46Trusted Source47Trusted Source).

Adding some salt to entire foods to improve taste is fine, but eating huge quantities from processed foods could very effectively trigger hurt.


Processed meat products include large quantities of salt, which can contribute to some health issues.

Take Home Message

Processed meat contains various chemical compounds that aren’t current in fresh meat. Many of these compounds are dangerous to health.

For this motive, eating loads of processed meat products for a protracted interval (years or many years) could increase the chance of persistent disease, particularly most cancers.

However, eating them often is fine. Just be sure to not allow them to dominate your diet and keep away from eating them each day.

At the top of the day, you must restrict your intake of processed foods and base your diet on fresh entire foods. (How bad is Processed Meat)
