American Cancer Society has signaled a change in the approach to the fight against cancer, when it announced that it will support further research to study the role of diet in cancer prevention. This shift reflected the findings of recent studies have shown that some foods or nutrients appear to play a protective role against cancer, while others are to promote disease.
Diet and colon cancer.
men who consumed a diet high in fat and low in fiber are 3.7 times more likely to develop adenomas than those who ate low-fat, high fiber diet. Men who ate more red meat, chicken and fish are also at greater risk of developing adenomas.
Harvard researchers have found similar results in previous studies of fiber and fat intake among ženama.Rezultati also supports the research of other scientists who apply a high fat intake and low fiber consumption with increased risk for colon cancer, which claims the lives of 58,000 Americans each year.
Folic acid and cancer of the cervix. The researchers, led by nutritionist Charles E. Butterworth of the University of Alabama at Birmingham found that folic acid deficiencies in the blood increased incidence of precancerous condition known as cervical dysplasia (abnormal growth of cells in the cervix, the opening of the uterus) in women who are already at risk for diseases . Cervical cancer is the ninth leading cause of cancer death in the United States.
Low folate levels seem to increase the harmful effects of such risk factors as smoking, multiple sexual partners, and infection with sexually transmitted virus called human papilloma virus (HPV ).

...Researchers have hypothesized that folic acid can protect cells from cancer-causing by the cells' genetic material less susceptible to HPV infection. Folic acid is a vitamin found in foods such as leafy, green vegetables and some meat.
Baby cholesterol levels.
Baby cholesterol levels.
...group reached its conclusions after reviewing numerous studies show that high blood cholesterol levels among children play a role in the development of coronary artery disease later in life. Coronary artery disease-the leading cause of death among Americans, occurs when cholesterol builds up on the inner walls of the arteries and restrict blood flow to the heart. Studies have shown that this build-up can begin in childhood. Saturated fats, found mainly in animal products, it seems to contribute to this process.
panel urged the food industry and schools to give children an attractive alternative to high fat and high cholesterol foods. He also suggested that health professionals, government agencies and the media play an active role in educating the public about healthy eating habits.
Diet and mental development.
British study malnourished children in Jamaica found that slows the development of children's mental abilities may become equal to those of healthy children after they receive proper nutrition and a stimulating play with their mothers.
for two years, researchers studied 129 slow infants and toddlers who are in the range from 9 months to 24 months of age. Thirty-two healthy children served as the basis for usporedbu.Usporava children are tested to make sure that their poor growth due to malnutrition, not a disease or some other poremećajem.Istraživači children were then assigned to one of four groups.
The first group received no intervention sve.Druga group received supplements samo.Majki third group received special instruction and encouragement for one hour a week playing with his group received djecom.Četvrta and nutritional supplements, and weekly sessions of play.
