Antioxidant levels key to prostate cancer risk in some men

Greater levels of selenium, vitamin E and the tomato carotenoid lycopene have been shown to reduce prostate cancer in one out of every four Caucasian males, or those who inherit a specific genetic variation that is particularly sensitive to oxidative stress, say US researchers.

Conversely, if carriers of this genetic variant have low levels of these vitamins and minerals, their risk of aggressive prostate increases substantially, as great as 10-fold, over those who maintain higher levels of these nutrients, they write in today’s issue of Cancer Research.

"This large prospective study provides further evidence that oxidative stress may be one of the important mechanisms for prostate cancer development and progression, and adequate intake of antioxidants, such as selenium, lycopene and vitamin E, may help prevent prostate cancer," said Dr Haojie Li, a researcher at the Brigham and Women's Hospital and Harvard Medical School.

The new findings are based on an analysis of 567 men diagnosed with prostate cancer between 1982 and 1995, and 764 cancer-free men from the Physicians Health Study.

The initial goal of this study was to assess the effect of aspirin and beta-carotene on men's health. Li’s team decided to check for variants of the gene that codes for manganese superoxide dismutatase (MnSOD), an important enzyme that works as an antioxidant in human cells to defend against disease.

The MnSOD gene is passed from parents to offspring in one of three forms: VV, VA or AA.

"Compared with men with the MnSOD VV or VA genotype, people with the AA genotype seem to be more sensitive to the antioxidant status," said Li. "Men with the AA genotype are more susceptible to prostate cancer if their antioxidant levels are low."

The study's results found that a quarter of the men in the study carried the MnSOD AA genotype, half carried the VA genotype, and the remaining quarter carried the VV genotype.

The results indicated that the VA and VV men were at equivalent risk for developing prostate cancer across all levels of antioxidants in their blood.

But compared to MnSOD VV or VA carriers in the lowest quartile of selenium levels, MnSOD AA males had an 89 per cent greater risk for developing aggressive prostate cancer if they had low blood levels of the mineral.

On the other hand, MnSOD AA carriers with high selenium – those men in the highest quartile – had a 65 per cent lower risk than the MnSOD VV or VA males who maintained low levels of selenium.

"The levels of selenium in the highest quartile of these men are not abnormally high," Li said. "Our range is neither extremely high nor extremely low."

While similar trends were observed for lycopene and vitamin E when tested independently, the contrast in relative risk was most pronounced for the men who had high blood levels for all three antioxidants combined, said the researchers.

"Among men with the MnSOD AA genotype, we observed a 10-fold difference in risk for aggressive prostate cancer, when comparing men with high versus low levels of antioxidants combined,"said Li. "In contrast, among men with the VV or VA genotype, the prostate cancer risk was only weakly altered by these antioxidant levels."

"Our study, as well as many other epidemiological studies, encourages dietary intake of nutrients such as lycopene from tomato products, or supplements for vitamin E and selenium to reduce risk of prostate cancer," said Li.

Prostate cancer is one of the biggest cancer killers in industrial countries and affects more than 500,000 men worldwide every year. This number is expected to increase with the ageing population.

Similar interactions between dietary antioxidants and the variations in the MnSOD gene have previously been linked to risk for breast cancer.

How secure is your diet?

Live diet properly in accordance with the requirements in order to harm health.

Various types of diet.
We must choose the right diet because everyone has different body conditions. Learn the first type of diet that is popular, especially the advantages and disadvantages of each.

Atkins diet
Popular in 2000 was discovered by Dr. Robert Atkins. The body will burn fat reserves when the body is no longer carbohydrates as fuel. Eat, which consumed the bulk of protein and fat, like cheese, eggs, and butter. This diet is already proven to reduce weight quickly. Can lose weight up to 7 pounds in 6 months.
high protein diet can aggravate the kidneys and liver. The minimal consumption of vegetables and fruits can also create a deficiency of vitamins, minerals, and fiber, as a result the body can not function normally.

South beach diet
Dr. beginning. Arthur Agatston created this diet to help patients lower cholesterol and blood sugar. Foods that may be consumed must be in accordance with the phase of the diet, with processed foods and soft drinks as a prohibition. South Beach diet can lose weight up to 6 kg in only 2 weeks in the first phase, but it is believed to prolong life and maintain health.
This diet was initially difficult to follow because you have to forget about favorite foods and beverages, such as potatoes, bread, cake and ice cream. Although proven to lose weight, not actual fat content is reduced, but the water content in our body.

Bloodtype diet
Dr. Peter J. D'Adamo, a naturopathic expert, has the idea that blood type is of key importance in determining the appropriate foods. By eating foods according to blood type can reduce the risk of diseases such as cancer, diabetes, and heart, while keeping the stability of body weight,
many nutritionists who has yet to confirm this study and assume that this theory is not based on scientific literature.

Choosing the appropriate type of diet.
Here are some tips on choosing the right diet and appropriate diet that will be undertaken in order to not harm the body.

1. Learn.
    Collect a lot of information and also underlies our considerations with
     nutrition expert opinions and research results of the study.

2. Beware of side effects.
    Recognize past medical history of the body, if suffering from
    Certain diseases such as anemia, allergies or high blood pressure make sure
    we express the dietician.

3. Discipline.

Healthy thanks to fiber

Fiber not only useful for digestion, fiber also keep a healthy heart, lowers risk of stroke, diabetes and diet help.
A study will be dietary habits and healthy lifestyles in Europe, Japan and the U.S. say they consume 3-5 servings of fiber a day had a reduction of stroke by 11%

WHAT IS FIBER ?

Fiber is a special form of carbon that does not change the chemical nature, despite being past the digestive processes in the human body. Found in fruits, vegetables and whole grains. Fiber is not digested and excreted from the body with the help of peristaltic motion of the intestines. Because this is not digestible fiber helps the process of disposal of leftover food in the body.

VARIOUS IMPORTANT BENEFITS OF FIBER
Some diseases can be prevented by consuming fiber with regularly, including:

Heart disease
Fiber affect cholesterol and blood sugar. Fiber also prevents hardening of the heart's blood vessels until smooth blood circulation and vital substances such as oxygen and iron can spread very well.

Cancer
Fiber speeds up metabolism and can prevent the deposition of toxic substances in the colon that can develop into colon cancer. Besides fiber also helps prevent breast cancer, ovarian cancer and prostate cancer.

Diabetes
Adding fiber in our diet every day to help stabilize blood sugar levels in the body. Up to avoid diabetes. For people with diabetes, fiber helps reduce blood sugar spikes increase and reduce the release of insulin excess by holding the process of change carbohydrates into sugar.

Stroke
Help fight hypertension, a major cause of stroke.

Overweight
Helps keep your weight by giving full effect as long to control hunger.

Slim healthy

Ideal body slim and healthy, is everyone's dream. Unfortunately, many people have misconceptions when on a diet.

Ideal body, slim and healthy, not only gives us the confidence but also makes us more nimble and move freely while performing everyday activities. Not surprisingly, many people perform a variety of ways in order to reduce excess fat in the body. Unfortunately after successfully reduced body weight, which often happens, the body became loose.

Unhealthy lifestyle, poor diet, excess intake of food, as well as the difficulty of finding time to exercise is a problem common cause of the problem of excess fat. Calories from a variety of food that enters the body, not after a fire due to lack of exercise until the end portion accumulates and is stored as fat. Body so not ideal.

Indiscriminate diet can cause a person to lose more muscle than fat. It is less profitable. The more lean muscle mass means fewer owned to make the body's metabolism running smoothly. Though the body needs to maintain muscle from bone fractures due to falls or injuries, because muscles function as a protective cushion. For that we must carefully choose how to diet. We must also carefully determine the supplement to help the formation of the ideal body. One of the natural ingredients that can enhance the metabolism of fat is CLA (conjugated linoleic acid).

CLA is found in everyday foods such as in meat, cheese, milk, egg yolks, fruits and others. To obtain sufficient amounts of CLA, we need to consume lots of foods that contain sources of CLA. But the high number of calories might even add to the deposit of fat in our body. The result of fat deposits in the body is not reduced but actually increased.

African mango provides a solution for those of you who want the ideal body shape with a combination of diet, cardio exercise, strength training and supplement the African mango ideal body must be ours.

Fit and healthy into old age

Want to have a healthy body and fit into old age?
Set the strategy from now!

When young we did have a lot of energy to undergo a variety of activities. But with age, the function of organs such as kidneys, lungs and immune system will also decrease. For that we need a strategy so that in later old age our bodies stay healthy and fit.

One strategy that we can do is to maintain adequate nutrition is important to maintain stamina and physical health. It is advisable to avoid smoking, eat healthy foods, eating foods that contain less fat, avoid eating too much salt, do regular physical activity and thinking positf.

Health problems are often experienced in later life:
decline in memory, menopause that occurs in older women, prostate enlargement in older men,
immune deficiencies, disturbances in bone and joints, problems in the joints that causes are not free to move,
degenerative diseases, such as diabetes mellitus, hypertension, high blood pressure.

In order for our health can be maintained and productive life as long as possible, we need to eat nutritional factors. The meaning of these nutrients are substances contained in food that the body needs to function properly. The body needs about 50 kinds of nutrients. A healthy body can form a perfect 25 of the 50 nutrient. Nutrients can be classified in six groups, namely carbohydrates, fats, proteins, minerals, vitamins, and water. All of these nutrients can be classified into three categories, namely:
nutrients that provide energy for the body movements and reactions, which are classified as carbohydrates, fats, and proteins.
Nutrients that build and repair body (a body building materials). Which belong to this group are water, proteins, fats, carbohydrates, and minerals.
Nutrients that serves as a lubricant various chemical and physical reactions in the body. Included are vitamins and minerals.

Beware of joint health

In addition to bones, joints that act as shock absorbers should also be considered health, so that we remain active in their daily activities.

Osteoarthritis is a joint disease that is often found that can cause disability, this occurs mainly in old age. However, it can also be found in people who are relatively young, as influenced by other factors such as the many activities (eg standing, walking, running and jumping) and obesity. Osteoarthritis (OA) or often referred to as calcification of the joints is a state where there is damage to joint cartilage. This cartilage serves as a cushion that serves to shock absorbers when two vertebrae are in conflict when our joints moving. If this is ignored then it would be very disturbing, if there is movement of the two vertebrae will feel pain.

People often do not feel the damage to this bone damage because they travel clinic is running very slow.

How to prevent?

To slow the process of joint destruction, there are several nutrients that our bodies must be met, ie containing the nutrients glucosamine. Prevention programs aimed at avoiding the emergence of OA, as well as slowing down the cartilage damage.

Nutrition for child growth

health children

Good nutrition will support the growth of children. Nutrition Meet the needs of our children every day, so as not susceptible to the disease in the future growth and development.

Because good nutrition will reduce the risk of children developing the disease. Even if there are germs or viral infection, with good endurance, the child will not easily hurt, so it does not interfere with the growth process.

Meet the nutritional needs of children with a balanced diet that contains carbohydrates, fats, proteins, vitamins and minerals that are appropriate for their needs. Indeed there are times when a child is difficult to eat, but we do not give up so easily. Maneuvering by always providing healthy snacks in the house that contains the elements of balanced nutrition and food additives that can cover the lack of intake of certain nutrients.

Anything that takes our children to grow flowers? Here are some of the essential nutrients you need to know;

Protein
Protein needs of children is very large. Protein is a source of essential amino acids necessary for the builder substances for growth and the formation of serum proteins, hemoglobin, enzymes and antibodies as well as for regeneration of damaged cells and as an energy source.

Multivitamins and minerals
Additional foods containing multivitamins and minerals needed by the child to meet the nutritional needs are not satisfied by the daily diet. Especially for children who have difficulty eating and children with limited food choices.

Vitamin A
It's important to support the growth of the child and maintain eye health and increase body resistance to infection.

Vitamin B complex
Plays an important role in the metabolism of the body and maintain organ function, especially the nervous system. Can help increase your appetite for children who have difficulty eating.

Vitamin C
Plays an important role in helping to improve the child's immune to infection, and accelerate growth.

Vitamin D
Very important in helping the absorption of calcium and phosphorus and maintain healthy bones and teeth.

Vitamin E
Very well known as an antioxidant that keeps the body's cells from damage. Plays an important role in the process of metabolism, maintain healthy skin and muscle.

Mineral
Nutrients needed to support the development of the child. Often the need for these nutrients can not be met from the daily diet. Important minerals include:

Calcium Magnesium
Instrumental in the growth of bones and teeth, blood clotting process and development of nerve cells and brain.

Iron
Instrumental in the formation hemoglogin (RBCs) that transports oxygen throughout the body cells.

Live a healthy life optimally, now

Health is a very worthwhile investment. Therefore, make optimal healthy living as your daily habits. How do I? Follow the 15 tips below:

1. Meet the nutritional needs
    Pay attention to the nutritional content of our foods contain a complete composition, including
    karbohidarat, proteins, fats, vitamins and minerals.

2. Avoid harmful fats
    Not all fats are bad, because it's important for us to consider the type of fat that we consume.
    Fried foods,butter and snack foods often contain trans fats which can increase the risk of heart
    disease. Healthy fats such as omega 3,6,9 fatty acids actually can reduce the risk of heart disease.
    Eat 3-4 servings of fish a week to increase the intake of healthy fats in our body.

3. Do not forget breakfast
    In order to have enough energy, we need breakfast every day. Even when you are in
    a weight loss program. Breakfast is still the recommended. When the fear of weight gain,
    reduce the portion of carbohydrate at lunch and dinner to control calorie intake.

4. Eating enough vegetables and fruit
    Consumption of fruit and 5-7 servings of vegetables every day to help meet the needs of vitamins,
    minerals and fiber every day.

5. Drink
    Because they most of our body is water, fill the body's need for water, at least 8 glasses a day.

6. Maintain ideal body weight
    Underweight, as dangerous as being overweight. Therefore maintain our ideal weight.

7. Sports
    Besides being able to improve fitness, exercise can also help the body's metabolic processes.
    Do exercise 3-4 times a week with a duration of 1 hour. Select the type of exercise appropriate
    body condition.

8. Adequate rest

      Often in the busyness makes us forget ourselves. Take time for hobbies so that we
      reduce the stress that can interfere with health.

12. Note the cleanliness
      Bath twice a day, wash hands before eating and after the move, brush your teeth twice a day,
      it could be a very modest first step in maintaining our health.

13. Regular health check
      Regular health check, at least once a year to avoid the possibility of occurrence of the
      disease early.


14. Select natural ingredients
      Limit consumption of processed foods, choose natural materials as a source of food,
      beverages and supplements for natural materials are more acceptable to the body,
      compared with the chemical (synthetic)

15. Supplement consumption
      Many people do not get enough vitamins and certain nutrients due to diet and lifestyle
      that are less good. Dietary supplement will help ensure the nutritional needs of everyday.
      Select in accordance with the conditions and needs of the body, and made from
      high quality natural ingredients making it safe for our health.

Screening Tests for Prostate

Prostate cancer is the second leading cause of death in men after lung  cancer, and the most common cancer in men. Fortunately, since most prostate  cancer is slow growing, only 30 percent of men diagnosed with prostate cancer  will die from it. So far, research has not confirmed that early detection of  prostate cancer leads to treatment that will prolong life. Testing is needed to  screen for prostate cancer to improve treatment.

There are two methods used to screen for prostate cancer in men. First there  is a blood test used to measure PSA (prostate specific antigen), a protein  produced by the prostate gland. PSA levels tend to rise when prostate cancer is  present. Unfortunately, the test has both high false positives and high false  negatives making results questionable. The test also cannot distinguish if the  prostate cancer is slow growing and unlikely to cause symptoms, or a highly  aggressive form. The other important screening test is the digital rectal exam  (DRE), where a doctor inserts a gloved finger into the rectum to feel for lumps  or irregularity of the prostate. The DRE has an 85 percent false positive rate,  where abnormalities felt but cancer is not present. If either the PSA or DRE is  abnormal, further evaluation is warranted. A prostate biopsy may need to be  performed, using a needle, which is inserted into the prostate through the  rectum. Biopsy is the only truly effective test that can prove if cancer cells  are present.

Prostate cancer can be treated by a variety of means. The treatment decision  must be based on the appearance and spread of the cancer, general health  condition, one's symptoms, and how each individual weighs the potential risks of  the different therapies offered. No therapy has yet proven to extend life,  although some treatments may reduce symptoms making life much more bearable.  Options include watchful waiting, radiation therapy, prostatectomy, and hormone  therapy. Each option has potential and serious side effects.

PSA screening should be optional for men at average risk of contracting  prostate cancer. Advice varies for when PSA are beneficial, and when PSA  screening are recommended. The American Cancer Society and American Urological  Association both recommend offering PSA screening to men ages 50 to 70 at  average risk, with appropriate counseling. African American men and men with  family members who have developed prostate cancer before age 70 are at much  higher risk. These men should discuss prostate-cancer screening with their  doctors.

Early detection of eye cancer in children

Until recently, of the many cancers that can be found in children, only one type that can be detected early, which is cancer of the eyeball or retinoblastoma.

Usefulness of early detection

This early detection is an effort to find cancer in its early stages. If the cancer can be known at an early stage, then the chances for recovery is greater than if discovered at an advanced stage.

Associated with a cancer that affects children, it is important for parents to detect early. Although only one type of cancer in children that can be known, early detection is still necessary to determine their level so they can take action more quickly.

Early detection of retinoblastoma in children to determine the so-called "CHECK RED". Examination is not necessarily done by a doctor on duty at a large hospital. A health worker who had been trained to be able to do so. Retinoblastoma attacks children under five, resulting in the examination process, the child will be asked to sit on her knees, while the examiner was not far from the front of them. Examination using an instrument called an ophthalmoscope, an instrument to see the inside of the child's eyes examined.

When the eyes of a child under normal conditions, the examiner by means of an ophthalmoscope to see the red color reflected from the eyes of children. When the tool is not there a red reflection, but even look cross-eyed, then the examiner will advise parents to bring their children to health facilities more complete. Therefore, it is important for the examiner to know beforehand whether the child is examined cross-eyed or not.

For that parents would be expected to check their children once a year for as young as toddlers. No parent who hoped their children affected by retinoblastoma, and therefore remain alert to the symptoms of cancer in children.

Miracle of green tea for health

Why is green tea so special?

The secret of green tea lies in the womb, of which is rich in catechin polyphenols and theaflavins that are part of epigallocatechin gallate (EGCG), a powerful antioxidant. The active ingredient of theaflavins also played a part in giving color and flavor that can be a measure of the quality of tea.

Benefits of green tea for health
 
many researchers who have managed to reveal the wonders of green tea, including the National Cancer Institute that suggests that green tea lowers the risk of esophageal cancer efficacious (esophageal cancer). Perdue University in the United states that the consumption of green tea prevents the growth of cancer cells. Research results Erasmus University Medical School in windmill country, the Netherlands, which revealed a large vein (aorta) of people who like to drink green tea has a coating that protects from the occurrence of blood clots, thus reducing the likelihood of coronary heart attack.

Several other studies also showed that green tea can lower total cholesterol levels, as well as improving the ratio of good cholesterol and bad cholesterol in the body.

With decreasing bad cholesterol (low density lipoproteins (LDL)), then the benefits of green tea:
1. reduce the risk of plaque formation in blood vessels.
2. Reduces existing plaques in blood vessels.
3. Prevent blockage of blood vessels.
4. Lower risk of heart disease
5. reduce the risk of stroke.

To lower cholesterol levels in the blood, also needs to be supported by a healthy lifestyle such as losing weight is not overweight, exercise routinely and regularly, maintaining a healthy diet, and avoiding or quitting bad habits like smoking, and do not forget to eat additional supplement that contains green tea extract which can help keep blood cholesterol levels.
