The researchers found that drinking lots of coffee actually reduces the risk of cancer of the mouth and larynx. The findings of the WebMD , people who drink more than four servings of coffee per day were randomly around 40% less than contracting mouth or throat cancer compared with people who do not drink coffee. For those who drank five cups of coffee per day, the level of protection was still consumed significantly less than 4% chance of developing cancer of the throat and mouth for every cup of coffee per day. Protection for the mouth and throat cancer was clear, but the protection against cancer of the larynx was not. Coffee protective effect was shown to remain intact for drinkers and smokers, despite the fact that cancers use tobacco and alcohol in the head and neck are linked. In addition, the protective effect did not prove to protect a boost to consumption of fruits and vegetables, which are also known for head and neck carcinomas. Researchers at the University of Milan reached these conclusions when they reviewed nine studies comparing 5139 individuals with head and neck, with 9028 people without cancer. So, what ingredient in coffee is responsible for reducing the risk of cancer of the mouth? The study has shown caffeine as a likely possibility, given that drinking tea, even in small quantities and has no protection. The researchers noted that coffee contains hundreds of chemicals. Among those kahweol cafestol and have anticancer properties. However, future studies should determine more determined when these chemicals actually protect against cancer in humans. Previous studies have

trigonelline in Wired Magazine, an alkaloid found in coffee credited as the fight against the cavity agent. Although the ingredients are well known for its coffee flavor, it is also found to inhibit the formation of craters in the teeth, preventing the bacteria Streptococcus cause tooth decay affiliates. The American Dental Association reminds us that coffee is not enough to provide optimal dental health. In fact, excess coffee stain teeth. The ADA recommends

traditional dental hygiene which includes brushing twice a day, flossing daily, a balanced diet and regular visits to the dentist.

In a study in the journal Human Reproduction, was published, researchers have found that the consumption of foods low fat milk each day lead to an increased risk of infertility. The study found no difference between women who ate the most dairy foods, and those who ate little or nothing. Scientific, Dr. Jorge Chavarro of the Harvard School of Public Health and Brigham and Women’s Hospital and Harvard Medical School in Boston followed 18,555 women aged 24-42 with no history of infertility, trying to become pregnant or had became pregnant was zwischen 1991 and 1999. The women were part of a much larger study of 116,000 women in the Nurses’ Health Study II asked every two years, the women a questionnaire, as if she had tried for more pregnant a year without success, and what was the reason, if they were not capable of thinking. Women also have information on how often on average they had consumed certain foods and beverages during the past year delivered. In eight years, 438 healthy women reported infertility due to ovulatory disorder. Adjusted for such factors as age, parity, body mass index, total caloric intake, physical activity, smoking, alcoholism and use of contraceptives, researchers found that women who have more than two servings per day eating dairy products low in fat were 85 percent more likely to be infertile due to ovulatory disorders than those who ate at least once a week. and a reduced risk of 27% of infertility in women eating fat dairy products (including ice) once or more per day compared to women eating a serving one or fewer per week. The study found no association between regular consumption of lactose, vitamin D, calcium and phosphorus, and infertility due to ovulation disorders. Once the women trying to get pregnant should consider the low-fat dairy products rich in milk fat. A substance soluble in fat dairy products may be responsible for improved ovarian function.

higher levels of selenium, vitamin E and carotenoids lycopene from tomatoes has been detected prostate cancer in a reduction of four white males, or those who say that a specific genetic change is particularly sensitive to stress oxidative die, U.S. researchers. Conversely, if carriers of this genetic variant have low levels of these vitamins and minerals, their risk of substantial increases in aggressive prostate cancer, as large as 10 times for higher concentrations 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 most important mechanisms for the development and progression of prostate cancer, and an adequate intake of antioxidants such as selenium , lycopene and vitamin E may help prevent prostate cancer, said Dr. Li Haoji, a researcher at Brigham and Women’s Hospital and Harvard Medical School. The new results are based on an analysis of 567 men with prostate cancer, 1982-1995, and 764 men without cancer study physicians diagnosed health is based. The initial aim of this study was to evaluate the effect of aspirin and beta-carotene to assess the health of men. Li team decided to test variants of the gene that codes for manganese superoxide to dismutatase (MnSOD), an important enzyme that works as an antioxidant in cells of the rights to defend themselves against the disease. The MnSOD gene is carried by parents to children in one of three forms: VV, VA or AA. “with men with the MnSOD VV or VA genotype comparison, people more sensitive to antioxidant status with the AA genotype seem, “said Li continued. “Men with the AA genotype are more susceptible to prostate cancer if their antioxidant properties are weak.” The results of the study revealed that a quarter of the men carried the MnSOD AA genotype of the study, half of which carried genotype VA, and the remaining quarter carried the VV genotype. The results showed that VA and VV men were at equal risk for prostate cancer at all levels of antioxidants in the blood. But MnSOD VV or VA carriers

in the lowest quartile of selenium levels, MnSOD AA compared with men had a risk of 89 per cent more likely to develop aggressive prostate cancer s if they had low blood levels of the mineral. On the other hand, MnSOD AA carriers had maintained with high selenium – men in the highest quartile – the risk 65 percent lower than the MnSOD VV or VA males, low selenium. “Selenium levels in the highest quartile of these men are not exceptionally high,” Li said. “Our offer is not very high nor very low.” ; Similar trends were observed for lycopene and vitamin E when tested independently, the contrast in relative risk was combined with men, blood pressure values for the three antioxidants had said, according to researchers. ” ; / P> “Among the men with the MnSOD AA genotype, we have a difference of 10 times the risk of aggressive prostate cancer, observed when comparing men with high versus low levels of antioxidants handsets, “said Li.” In contrast, among men with the VV or VA genotype, the risk of prostate cancer changed little by these antioxidant levels has been. “” Our study Like many other epidemiological studies, promotes the absorption of nutrients such as lycopene from tomatoes or supplements of vitamin E and selenium reduce the risk of prostate cancer, “Li said. ; Prostate cancer is a leading cause of cancer mortality in industrialized countries and affects more than 500,000 people per year worldwide. This number should increase with the aging of the population.

similar interactions between antioxidants and the variations in the MnSOD gene have been associated with the risk of breast cancer. For more information: Prostacet
