Best food diet: Why the processed meat is bad for you

Man eating meat Processed meat is generally considered unhealthy.

It has been linked to diseases such as cancer and heart disease in numerous studies in connection.

There is no doubt that the treated meat contains a lot of harmful chemicals that are not naturally present in fresh meat.

This article takes out a detailed health effects of processed meat.

The meat processing?

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

The food products such as sausages are classified:

Sausages, sausages, salami.
Bacon ^[1] , ham.
Salted and sausage, corned beef.
Smoked meat.
Dried meat beef ^[2] uneven.
Canned meat.

In addition, the meat has been frozen or mechanical treatment as cutting and cutting raw yet considered.

Conclusion: All meats that have smoked, salted, smoked, dried or canned as a contract. These include sausages, sausages, salami, bacon and ham.

Eating processed meat is associated with an unhealthy lifestyle

Meat products has always associated with adverse health effects.

This is a fact that people worried about his health have to be known for decades.

Therefore, high amounts of processed meat diet in people with unhealthy lifestyles is more common.

In fact, smoking is more common in those who eat a lot of processed meat. Consumption of fruits and vegetables, is also much lower ( 1 , 2 ).

Most observational studies to try to processed meat and health consequences, to correct these factors. However, these methods are not perfect.

You can find the links between gum disease and partly due to the fact that people who tend to eat processed meat to other things that are not connected to good health to do.

But studies show strong links between the consumption of processed meat and various chronic diseases.

Bottom Line: People who do not have health tend to eat more processed meats. This may explain, in part, some of the associations found in studies on the consumption of processed meat and disease.

In meat, it is linked to chronic diseases

Eating processed meat is associated with an increased risk of many chronic diseases.

These include:

High blood pressure (hypertension) ( 3 , 4 ).
Heart disease ( 2 , 5 ).
Chronic obstructive pulmonary disease (COPD) ( 6 , 7 , 8 , 9 ).
Stomach cancer and colon cancer ( 2 , 10 , 11 , 12 , 13 , 14 ).

Studies are handled through the consumption of meat in humans all observation.

You can show that people who eat meat are processed rather to get these diseases, but they can not prove that the meat she has caused.

Although the evidence is convincing, because the links are strong and consistent.

In addition, all are supported by animal studies. For example, studies in rats show that eating processed meat increases risk of colon cancer ( 15 ).

One thing is clear, the treated meat contains harmful chemicals that may increase the risk of chronic diseases. The compounds tested are explained below.

Conclusion: Eating large amounts of processed meat over a long period can increase the risk for many chronic diseases such as heart disease and cancer.

Nitrites, N-nitroso compounds and nitrosamines

N-nitroso compounds are carcinogens believed responsible for some of the adverse effects of eating processed meat.

Formed from nitrite ^[3] (sodium nitrite) added to processed meat products.

Sodium nitrite is used as an additive for three reasons:

To maintain / red pink meat.
To the taste, by improving fat oxidation (rancidity).
To the growth of bacteria, which improves the taste, and prevents that the risk of food poisoning.

Nitrites and related compounds such as nitrate, are also in other foods. For example, nitrate found in relatively high levels in some vegetables and can even be beneficial to health ( 16 ).

However, nitrite is all the same. Nitrites in meat can be harmful N-nitroso compounds, the most widely studied are nitrosamines ^[4] ( 17 ).

Processed meat is the main food source of nitrosamines ( 18 ). Other sources are drinking contaminated water, smoke snuff, and salty condiments ( 17 , 19 ).

(Exposed to nitrosamines are formed mainly processed meat products at high temperatures (over 266 ° F or 130 ° C) because when frying or grilling sausages bacon 20 ).

Animal studies indicate that nitrosamines can play an important role in the development of colon cancer (to play 15 , 21 ).

This is demonstrated by human observational studies that nitrosamines may increase the risk of colorectal cancer (stomach and increase support 22 , 23 ).

Conclusion: Processed meat roasted or grilled can contain relatively high levels of nitrosamines. Studies suggest that these compounds may increase the risk of gastric cancer and colon.

Polycyclic aromatic hydrocarbons (PAHs)

Meat smoking ^[5] is one of the oldest methods of conservation, often used in combination with salting or drying.

This leads to the formation of different kinds of pollutants. These include polycyclic aromatic hydrocarbons ^[6] (PAH) ( 24 ).

PAHs are a large class of substances formed when organic material is burned.

They are converted in the air with smoke and accumulates on the surface of meat and smoked meat products (are grilled, fried or roasted over an open fire 25 , 26 ).

They may be formed from:

The burning of wood or coal.
Splashes of fat burning on a hot surface.
Burned or charred meat.

For this reason, smoked meat products in high PAH (be 27 , 25 ).

It is assumed that PAHs can certain harmful health effects of processed meat in.

Numerous animal studies have shown that some PAHs can cancer (cause 24 , 28 ).

In short: may contain smoked meat products high levels of polycyclic aromatic hydrocarbons (PAH). It has been shown that these compounds, which cause cancer in animals.

Heterocyclic amines (HCA)

Heterocyclic amines ^[7] (HCA) are a class of chemical compounds that are formed when meat ^[8] or fish ^[9] is fired at a high temperature, for example when frying or baking ( 29 , 30 ).

Sausages on the grill

You are not limited to processed meats, but can be found in large quantities sausage, bacon and beef burger ( 31 ).

HCA cause of cancer, when administered to animals in large quantities. Generally, these amounts are much higher than those normally used in the human diet (found 32 ).

Many people observational studies, however, show that the consumption of well-done meat may increase the risk of colon, breast and prostate cancer (increase 33 , 34 , 35 ).

HCA-level can be minimized with gentle cooking methods such as frying on low heat and steam. Avoid eating charred, blackened flesh.

Conclusion: Some processed meat products can heterocyclic amines (HCA), carcinogenic compounds that are also found in uncooked meat and fish, contain.

Sodium chloride

Processed meat products are usually high in sodium ^[10] known chloride, also known as sodium chloride.

For thousands of years salt is added to foods as a preservative. However, it is often used to improve the taste.

Although processed meat is by far not the only food that is high in salt, which can contribute significantly to the intake of salt for many people.

Excessive salt intake (to play have known hypertension, a role in high blood pressure and heart disease, especially in those who a condition known as salt sensitive 36 , 37 , 38 , 39 , 40 ).

Furthermore, let several observational studies that a diet high in salt can increase the risk of gastric cancer (increase 41 , 42 , 43 , 44 , 45 ).

This is evidenced by studies that show that a diet high in salt can the growth of Helicobacter pylori, a bacterium that stomach ulcers that a risk factor for stomach cancer (it causes to increase support 46 , 47 ).

A little salt, whole foods to improve taste okay, but the food of large quantities of processed foods, it can cause damage.

Conclusion: processed meat products contain large amounts of salt, which can contribute to health problems.
