Adipose tissue surrounding the prostate gland of men with obesity, creates favorable conditions for the progression of prostate cancer.

What is the prostate gland
The prostate gland - is musculo-glandular organ located below the bladder and surrounding the initial portion of the urethra. The main function of the prostate is to produce secretions, which is part of semen. Ducts of the prostate glands open into the urethra.

Prostate cancer
In the early stages of prostate cancer does not manifest itself. Complaints are associated with tumor spread and metastasis. At the stage the only manifestation of the lack of symptoms, allowing the disease to suspect, is to increase blood levels of prostate specific antigen (PSA). As prevention of prostate cancer for all men should conduct an annual PSA test beginning at age 45.

By increasing the size of the tumor shows the following symptoms:
  • Frequent urination
  • Difficulty urinating
  • Urinary incontinence
  • urge to urinate.
The essence of the study

Scientists have received samples of adipose tissue surrounding the prostate gland in men with benign prostatic hyperplasia, prostate cancer and prostate cancer. Regardless of prostate disease in men with obesity , there is increased activity of genes in fat cells. These genes encode proteins involved in the immune response, inflammation, growth, reproduction, and cell death.

Increase in the activity of genes leads to inhibition of the immune response and stimulates the formation of new blood vessels, which creates favorable conditions for the progression of prostate cancer. The study's authors hope that the findings will more carefully selected treatments for patients with obesity.

American researchers have found that each person has a nose specific detector fat. With it, we can determine the level of this substance in different products.

Scientists at the California Science Center have found another way to avoid overeating, which can be used along with counting calories and a careful selection of products. It turns out that the person in the nose has its own excellent for detection of fat smell given to us by nature. Researchers believe that people can easily incorporate this detector for the regulation of its power.

Scientists believed that the smell of food is almost always determined by the man before he eats anything. It turned out that one of the first components of this odor is received by us olfactory information about whether the food contains fat. And if using innovative technologies, food producers will smell of fat in food more perceptible for the health of society, it will lead to a significant roll in the general trend of development of a worldwide epidemic of obesity .

"Our sense of smell allows us to significantly better orientation in everyday life than we used to think - said study author Dr. Johan. - We have the ability to determine the difference in fat content in the diet, which means that this ability provides specifically for evolution, and it is important. From time immemorial, the fat has been source of energy in the human body, and we learned to recognize the smell of greasy food to get this energy. Similarly, the sweet taste of foods high in carbohydrates is a sign that we obtain the energy of carbohydrates. "

Fast food is not the main reason for the spread of child obesity . This was stated by U.S. researchers.

They believe that children addicted to such food - a side effect of bad eating habits.

The experiment was conducted by researchers from the University of North Carolina at one of the schools in the U.S.. He showed that many children from an early age parents or caregivers instill the wrong template power which is based on processed foods and sweetened beverages. That is why such children are more likely to be overweight and eating a fast food meal.

Thus, fast food structure is part of their diet. Not the products themselves, and bad habits are to blame for the occurrence of child obesity. This is a much more serious problem, say the authors of the study.

Diet and other lifestyle factors can have a significant impact on your risk of developing cancer. By getting enough exercise and eating a healthy diet full of fresh fruits, veggies and other whole, natural foods, you can lower your risk of developing all types of cancers.

Sometimes, simply knowing which foods to avoid can also help you to lower your risk, as certain ingredients have been shown to have a strong link to the development of cancer. Here are several ingredients that could be in your diet right now that could be increasing your risk of cancer:


Aspartame is one of the most commonly used artificial sweeteners, and much research has suggested that it can increase your risk of cancer. Research on the issue has been debated, as some feel that the evidence is not conclusive or that it only shows a correlation when very high amounts are used. However, it may be better to be safe than sorry and to avoid this artificial sweetener, which is found in everything from diet sodas to yogurt to ice cream. It is also sold under the brand names NutraSweet and Equal.


Nitrates are what are added to hot dogs, bacon and other processed meats (such as salami and deli meat) to preserve the meat and keep the color fresh. Sodium nitrates (the kind added to meats) are converted into nitrosamine in the body, which is a known carcinogen (cancer-causing agent). You can also find nitrosamines in fried and smoked foods.


Pesticides are commonly used on all kinds of fruit and produce in order to keep them free of bugs during the growing process. Unfortunately, many of these pesticides are carcinogenic. It is best to stick with organic produce that has not been sprayed with these dangerous chemicals. If you can't buy organic for all your produce, just focus on organic for the "dirty dozen", which are the produce that are sprayed with the most pesticides.

Hydrogenated Oils

Hydrogenated oils are regular vegetable oils that have been heated in the presence of hydrogen, which helps to prolong their shelf life but also creates carcinogenic trans fats. Hydrogenated oils are found in everything from fried foods to breads to cakes and cookies. Look for hydrogenated and partially hydrogenated oils on the package and avoid these foods.


Acrylamides are created when foods are fried, forming when starchy foods are exposed to very high heats. Studies have shown that acrylamides can increase the risk of several types of cancer. It's best to avoid fried foods and stick to their healthy baked counterparts and avoid these dangerous chemicals altogether.

While genetic predisposition is a big risk factor for cancer, your diet and lifestyle choices also have a big impact. It is important to learn about the harmful substances that could be in your foods and increasing your risk. Of course, choosing a whole-foods diet that is full of plenty of fresh fruits and vegetables is also one of the best ways to ensure that you are eating a healthy diet that will reduce your risk of cancer and many other diseases.

Americans have been increasingly concerned about weight gain in recent years, and with good reason. According to the Center for Disease Control and Prevention, one in three Americans is obese, making it common to speak of obesity as an epidemic a widespread problem that affects the society as a whole rather than an affliction of individuals who make poor eating decisions.

Who is Obese?

The obesity rate has fallen slightly in recent years and appears to have stabilized among children, but obesity does not affect all portions of the population equally. Obesity disproportionately affects those who with less money and education, as well as women. And obesity affects earning power and other forms of opportunity in turn: The obese earn as much as 18 percent less than those of "normal weight," according to a recent Organisation for Economic Co-operation and Development report. In light of these considerations, taxing unhealthy food an approach adopted by Denmark, Hungary, France and Finland is problematic because it puts the economic burden of obesity on those most directly disadvantaged by it.

Healthy Eating Begins in Childhood

According to Margo Wootan of the Center for Science in the Public Interest, the trick to reducing obesity is to change the way that children eat. Wootan says that by serving healthier lunches in schools and removing vending machines, we can habituate children to healthier eating. She also suggests that part of the problem is that 80 percent of food marketing aimed at children advertises unhealthy food an argument that recalls the controversy around cigarettes being marketed to children. Children who learn to eat healthfully are likely to remain healthy throughout their lives, while those who don't will face an uphill battle.

Preventing the development of obesity in children has been a common goal of many anti-obesity strategies. While such strategies may not produce the quick results that many of us would like to see, they could produce much healthier generations of adults in the years to come.

A Strategy for Prevention

The Institute of Medicine recently released a new strategy for preventing obesity in the United States. The strategy addresses the obesity epidemic from multiple angles, including restrictions on marketing unhealthy food to children, increasing the amount of physical exercise mandated in schools, making healthier food available to children in restaurants and using doctors to disseminate information and advice about healthy eating.

While obesity is a deep-rooted problem that isn't likely to disappear overnight, we can take steps to prevent it from spreading and to eventually reverse the trend. It seems clear that no easy answer or single strategy will solve the problem of obesity in our society, just as drastic dietary changes tend to produce temporary results for individuals. But approaching the problem from several different angles at once does seem more likely to produce results.
