Inflammation is a vital part of the immune system's response to injury and infection.

What happens when your DNA is damaged? - Monica Menesini

It is the body's way of signaling the immune system to heal and repair damaged tissue, as well as defend itself against foreign invaders, such as viruses and bacteria. Without inflammation as a physiological response, wounds would fester, and infections could become deadly. However, if the inflammatory process goes on for too long or if the inflammatory response occurs in places where it is not needed, it can become problematic.

But a healthy diet and lifestyle can help keep inflammation under control. Acute inflammation occurs after a cut on the knee, a sprained ankle or a sore throat. It's a short-term response with localized effects, meaning it works at the precise place where a problem exists. The telltale signs of acute inflammation include redness, swelling, heat and sometimes pain and loss of function, according to the National Library of Medicine. In the case of acute inflammation, blood vessels dilate, blood flow increases and white blood cells swarm the injured area to promote healing, said Dr.

This response is what causes the injured area to turn red and become swollen. During acute inflammation, chemicals known as cytokines are released by the damaged tissue. The cytokines act as "emergency signals" that bring in your body's immune cells, hormones and nutrients to fix the problem, Walker said. In addition, hormone-like substances known as prostaglandins create blood clots to heal damaged tissue, and they also trigger pain and fever as part of the healing process.

As the body heals, the acute inflammation gradually subsides. Unlike acute inflammation, chronic inflammation can have long-term and whole-body effects. Chronic inflammation is also called persistent, low-grade inflammation because it produces a steady, low-level of inflammation throughout the body, as judged by a small rise in immune system markers found in blood or tissue.

This type of systemic inflammation can contribute to the development of disease, according to a summary in the Johns Hopkins Health Review. As a result, white blood cells swarm but have nothing to do and nowhere to go, and they may eventually start attacking internal organs or other healthy tissues and cells, Walker said. Researchers are still working to understand the implications of chronic inflammation on the body and the mechanisms involved in the process, but it's known to play a role in the development of many diseases.

For example, chronic inflammation has been linked to heart disease and stroke. One theory suggests that when inflammatory cells stay too long in blood vessels, they promote the buildup of plaque.

The body perceives this plaque as a foreign substance that doesn't belong, so it tries to wall off the plaque from the blood flowing inside the arteries, according to the American Heart Association AHA. If the plaque becomes unstable and ruptures, it forms a clot that blocks blood flow to the heart or brain, triggering a heart attack or stroke. Cancer is another disease linked with chronic inflammation.

Over time, chronic inflammation can cause DNA damage and lead to some forms of cancer, according to the National Cancer Institute. Chronic, low-grade inflammation often does not have symptoms, but doctors can test for C-reactive protein CRPa marker for inflammation in the blood. High levels of CRP have been linked with an increased risk of heart disease. CRP levels can also indicate an infection, or a chronic inflammatory disease, such as rheumatoid arthritis or lupus, according to the Mayo Clinic.

Besides looking for clues in the blood, a person's diet, lifestyle habits and environmental exposures can contribute to chronic inflammation.Free radicals represent molecules that roam inside your body and damage the structure of your good cell, wreaking havoc on your health. In order to understand how dangerous they are you should know, that free radicals are responsible for many types of cancer, since they are very chemically reactive.

We are surrounded by the factors that increase the amount of free radicals in our body, such as air pollution, tobacco smoke even the passive smoking and radiation. But the good news is that with the right diet you can easily prevent their negative effects. Consider including these 6 foods in your diet in order to protect your DNA from damage and with that — slow down your aging processes as well as reducing the risk of cancer.

In the beginning researches treated these results with skepticism, thinking that eating broccoli only boosts your liver detoxifying enzymes, which prevent toxic chemicals from getting to your DNA. They removed DNA from the participants and placed it in a test tube. They then added known DNA damaging chemicals and waited for the results.

And that settled it — broccoli can indeed repair your DNA and protect them from chemical damage. This simple mineral that can be easily found in various sources of food and in form of supplements can help you prevent and even reverse the damage effects on your DNA, which was successfully confirmed by the Lnus Pauling Institute study at Oregon State University. You can find zinc in plenty of foods — some of them are pretty common and can be easily found at every store.

The best is seafood, especially oysters — 6 of them can provide whopping 77 mg of zinc. Others include beef 3 cooked beef shanks can grant you 9 mg of zinccrab meat, pork, chicken, cashews, Greek yogurt, etc. That is why you need to consider taking supplement.

For the best result take zinc supplement 1 hour prior to your meal or at least 2 hours after your meal. Oatmeal, whole wheat grain, brown rice or nuts are also very good for preventing the effects of free radicals, given the fact that they are rich in Vitamin E which not only prevents these molecules from affecting your health, but it also neutralizes the molecules that have already affected you.

Carotenoids are often called provitamin A because are the precursors to that group of vitamins. It is because of the Carotenoids orange and red foods get their vibrant color, in particular beta-carotene and lycopene respectively. Science has shown that carotenoids are able to stimulate the repair of DNA that may be responsible for disease and aging.

Carotenoids are also antioxidants, which means they help fight cancer. Beta-carotene is considered to be one of the most powerful natural antioxidants, as it neutralizes free radicals quickly and efficiently. It is very easy to spot foods rich in beta carotene, as they have an orange color.

Basically, look for all the foods that are orange. However, if you want to benefit from beta carotene at its full potential, you will have to consume at least four daily servings. Studies have pointed to a connection between vitamin D and reduced risk of certain cancers, especially colorectal cancer. Scientists say there is reason to believe vitamin D is able to stabilize the structure of DNA so that it is not damaged by free radicals, which is what leads to aging and cancer-causing mutations.

Avocados can be easily distinguished by their buttery appearance, but few people know that these fruits are highly beneficial. Avocados are high in monounsaturated fats perfect for lowering the levels of cholesterol and for keeping your heart healthy and they also contain polyphenols and glutathione, two great compounds that prevent fats from oxidizing.

In other words, if you consume avocado regularly you will not only prevent the effects of free radicals, but you will also neutralize the destructive fat in other foods. In addition to antioxidants, avocados are also rich in potassium, an essential compound that is vital for the protection of your blood cells.

How much man-made, toxic lab food can one ingest before negative symptoms show up? How much more sickness does this society have to endure before we finally stay united and demand more from our food system, through the choices we make every day?

His amazing discoveries have contributed to the developing, new and fascinating science of epigenetics we learn about today. In Pottenger began a study with the intention to find out more about the nutrient quality or difference of raw versus cooked meat, as well as raw versus pasteurized milk. And he wanted to know if meat and milk, when modified by high heat, had an impact on growth and development. Physical degeneration caused by a poor diet in the mother is inherited in the offspring and passed on through the third generation.

Pottenger discovered that poor health could, indeed, be reversed. The third generation of cats that developed health problems from the entirely cooked diet was the proof in this experiment. Pottenger started to feed these cats raw milk and meat and cod liver oil. What he noticed was that with the first generation of cats as well as with the three successive generations of kittens they produced — each kitten was healthier than the prior one.

So, what Pottenger discovered 70 years ago and what ancestral cultures have been knowing for centuries is that :. The food we eat each day influences illness or wellness, not only in ourselves, but in our children, grandchildren, even our great-grandchildren, born or unborn.

By breaking the links among local soils, local foods, and local peoples, the industrial food system disrupted the circular flow of nutrients through the food chain. Whatever the advantages of the new industrial system, it could no longer meet the bio-chemical requirements of the human body, which, not having had time to adapt, was failing in new ways.

Michael Pollan. Throughout our existence as humans, our genes have shown they are highly adaptable to the available food supply and a wide variety of diets. Our genes gradually adapted to new ways of eating and we continued to thrive. Populations that were exposed to milk and grains for the longest periods of time have inherited the ability to metabolize these foods. This way, 85 percent of hunter-gatherer Australian Aborigines can not tolerate lactose, while only 2 percent of Swedish people — who have been consuming dairy as a staple for a long time — have problems metabolizing lactose in milk.

Convenience and cheap prices were enough to fool people into believing that chemical concoctions sold widely in stores today can actually pass as food. As a result, each new gene amounts to a game of food safety roulette, leaving companies hoping that the new gene will not destabilize a safe food and make it toxic.

Andrew Kimbrell, GMO expert.Oxidative stress is an imbalance of free radicals and antioxidants in the body, which can lead to cell and tissue damage. Oxidative stress occurs naturally and plays a role in the aging process. A large body of scientific evidence suggests that long-term oxidative stress contributes to the development in a range of chronic conditions.

Such conditions include cancerdiabetesand heart disease. In this article, we explore what oxidative stress is, how it affects the body, and how to reduce it. Oxidative stress can occur when there is an imbalance of free radicals and antioxidants in the body. However, cells also produce antioxidants that neutralize these free radicals.

In general, the body is able to maintain a balance between antioxidants and free radicals. Several factors contribute to oxidative stress and excess free radical production. These factors can include:. This type of oxidative stress causes mild inflammation that goes away after the immune system fights off an infection or repairs an injury.

Uncontrolled oxidative stress can accelerate the aging process and may contribute to the development of a number of conditions. Free radicals, including reactive oxygen species, are molecules with one or more unpaired electron. Examples of free radicals include:. Cells contain small structures called mitochondria, which work to generate energy in the form of adenosine triphosphate ATP.

Mitochondria combine oxygen and glucose to produce carbon dioxide, water, and ATP.

Free radicals arise as byproducts of this metabolic process. External substances, such as cigarette smoke, pesticides, and ozone, can also cause the formation of free radicals in the body. Antioxidants are substances that neutralize or remove free radicals by donating an electron. The neutralizing effect of antioxidants helps protect the body from oxidative stress. Examples of antioxidants include vitamins A, C, and E.

Common Modern Foods Which Cause DNA Damage

Like free radicals, antioxidants come from several different sources. Cells naturally produce antioxidants such as glutathione.Radiation is the emission sending out of energy from any source. X-rays are an example of radiation, but so is the light that comes from the sun and the heat that is constantly coming off our bodies.

When talking about radiation and cancer, many people think of specific kinds of radiation such as x-rays or the radiation made by nuclear reactors. But there are other types of radiation that act differently. Radiation exists across a spectrum from very high-energy high-frequency radiation to very low-energy low-frequency radiation. This is sometimes referred to as the electromagnetic spectrum.

Examples of high-energy radiation include x-rays and gamma rays.

They, as well as some higher energy UV radiationare called ionizing radiationwhich means they have enough energy to remove an electron from ionize an atom or molecule.

This can damage the DNA inside of cells, which can result in cancer. Radiofrequency RF radiation, which includes radio waves and microwaves, is at the low-energy end of the electromagnetic spectrum. It is a type of non-ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to ionize remove charged particles such as electrons.

RF radiation has lower energy than some other types of non-ionizing radiation, like visible light and infrared, but it has higher energy than extremely low-frequency ELF radiation. If RF radiation is absorbed in large enough amounts by materials containing water, such as food, fluids, and body tissues, it can produce heat. This can lead to burns and tissue damage. Although RF radiation does not cause cancer by damaging DNA in cells the way ionizing radiation does, there has been concern that some forms of non-ionizing radiation might have biological effects that could result in cancer in some circumstances.

Some people can have significant RF exposure as part of their jobs. This includes PVC welders, people who maintain antenna towers that broadcast communication signals, and people who use or maintain radar equipment. Most people are exposed to much lower levels of man-made RF radiation every day due to the presence of RF signals all around us.

They come from radio and television broadcasts, WiFi and Bluetooth, cell phones and cell phone towersand other sources. Microwave ovens work by using very high levels of a certain frequency of RF radiation in the microwave spectrum to heat foods. When microwaves are absorbed by food containing water, it causes the water molecules to vibrate, which produces heat. Microwaves do not use x-rays or gamma rays, and they do not make food radioactive. Microwave ovens can cook food, but they do not otherwise change the chemical or molecular structure of it.

Microwave ovens are designed so that the microwaves are contained within the oven itself. The oven only makes microwaves when the door is shut and the oven is turned on. When microwave ovens are used according to instructions, there is no evidence that they pose a health risk to people.

In the US, federal standards limit the amount of radiation that can leak from a microwave oven to a level far below what would harm people.

Ovens that are damaged or modified, however, could allow microwaves to leak out, and so could pose a hazard to people nearby by potentially causing burns. Although some people have been injured from microwave ovens, most often they have been burns from contact with steam or hot food.

The scanners currently used by the TSA use millimeter wave imaging. These scanners send out a small amount of millimeter wave radiation a type of RF radiation toward the person in the scanner. The radiation is sensed by receivers that create images of the person. Millimeter wave scanners do not use x-rays or any other kind of high-energy radiation and the amount of RF radiation used is very low.

However, TSA often allows people to be screened in a different way if they object to screening with these scanners. Cell phones and cell phone towers use RF radiation to transmit and receive signals. Some concerns have been raised that these signals might increase the risk of cancer, and research in this area continues.Contributing Writer for Wake Up World.

Throughout our existence as humans, our genes have shown they are highly adaptable to the available food supply and a wide variety of diets.

This way, 85 percent of hunter-gatherer Australian Aborigines can not tolerate lactose, while only 2 percent of Swedish people — who have been consuming dairy as a staple for a long time — have problems metabolizing lactose in milk.

How about the new era of highly processed foods from the industrialized diet? Convenience and cheap prices were enough to fool people into believing that chemical concoctions sold widely in stores today can actually pass as food.

As a result, each new gene amounts to a game of food safety roulette, leaving companies hoping that the new gene will not destabilize a safe food and make it toxic. Andrew Kimbrell, GMO expert. For centuries humans have altered the genetic characteristics of plants naturally by selecting seeds from plants with desirable physical characteristics, such as taste, size and color.

The genetic code of GM plants has been modified by humans, whereas hybrid plants create their own genetic structure! When researchers Ian F. Pryme and Rolf Lembcke conducted in vivo studies about the possible health consequences of genetically modified food, they concluded that genetic engineering creates widespread genetic mutations in hundreds of thousands of locations throughout the genome!

It starts with digestive problems, lowered immunity and eventually tumors and cancer. With the advent of the Industrial Revolution and the processing of omega 6-rich vegetable oils- such as corn, soybean, canola and safflower oils- that are so abundant in our diet today — the balanced ratio of omega 6 and omega 3 fatty acids on which our human genome thrived for hundreds of thousands of years changed drastically.

These days, it is estimated that we eat one-tenth of the amount of omega 3 fatty acids required for normal functioning.Salmonella food poisoning wallops you for several days, but new research by Cornell food scientists indicates that some of its serotypes — variations of the bacterial species — can have permanent repercussions.

It may damage your DNA. Salmonella causes about 1. There are over 2, serotypes for salmonella, but fewer than serotypes cause the vast majority of foodborne illness, according to the CDC. Miller and Martin Wiedmann, the Gellert Family Professor in Food Safety, examined multiple serotypes of salmonella that encode for cytolethal distending toxin, or S-CDT, a virulence component for serotype Typhi — the cause of typhoid fever. As it happens, the salmonella serotypes called Javiana, Montevideo, Oranienburg and Mississippi — common culprits in the foodborne illness world — also carry the genetic material that encodes S-CDT, the researchers found.

In human cells grown in the lab, Salmonella strains with S-CDT were also found to lead to hallmark signatures that indicate the presence of DNA damage. The ability to cause DNA damage may contribute to long-term disease consequences, Miller said. For a half-century, scientists have used salmonella serotyping to track foodborne illness outbreaks and their sources. Mwho received the first doctorate of veterinary medicine in the United States.
