Carbonated beverages may put young girls at risk of breast cancer, according to a new study.
Researchers from the Harvard Medical School found that drinking just one-and-a-half cans of fizzy sugary drinks increases their cancer risk by five percent and causes early puberty. The scientists looked at 5,583 girls aged 9 to 14 who drank more than 1.5 servings of sugary drinks a day and had their first period 2.7 months sooner than those who consumed two or less drinks a week, according to The Telegraph.
Drinks with added sugar can increase the concentration of insulin in the body, which turns into higher concentrations of sex hormones, normally associated with early onset of menstruation. Associate Professor Karin Michels wrote in the journal Human Reproduction that the team’s primary concern is about childhood obesity “but our study suggests that age of first menstruation (menarche) occurred earlier, independently of body mass index, among girls with the highest consumption of drinks sweetened with added sugar, according to The Telegraph.
Michels noted that a one-year decrease in age at menarche is estimated to increase the risk of breast cancer by five percent, “thus, a 2.7 month-decrease in age at menarche likely has a modest impact on breast cancer risk,” The Telegraph reported.
The study found that girls who drank 1.5 servings of sugar-sweetened drinks a day were 24 percent more likely to start menstruating a month earlier. The average age of the girls involved in the study who consumed the most sugary beverages was 12.8 compared to 13 years for those drinking the least. At the time of study, none of the girls had started their periods. When researchers adjusted results to take account of BMI, the effect of sugary drink consumption on the age of onset of menstruation was still significant, according to The Telegraph.
Girls who consumed the most soda and sugary drinks were 22 percent more likely to start their first period in the next month compared to girls who consumed the least. Previous research has shown that higher levels of caffeine intake is linked to earlier periods, but the researchers in this study found that total sugar or caffeine consumption did not explain their results. The team found that added sugar was the culprit, The Telegraph reported.
Dr. Michels added: “This research shows that it’s even more important that children switch to water.”
J.J. Fuds recalled its Chicken Tender Chunks Pet Food after routine sampling by the Michigan Department of Agriculture and Rural Development resulted in a positive result for Listeria monocytogenes, the FDA said in a press release posted on the agency website. The company says it is working with distributors and retailers to properly dispose of any affected product still on freezer shelves. J.J. Fuds also says it is working with distributors and retailers to notify pet owners of the recall and inform them of how to properly dispose of any affected product they purchased.

E-cigarettes are growing in popularity, so much so that the editors of the Oxford Dictionaries declared “vape” their Word of the Year for 2014. But two of the nation’s major cancer science and treatment groups are calling on the government to regulate the devices and increase research on the health effects of vaping.
In a joint statement, the 35,000-member American Society of Clinical Oncology and the 33,000-member American Association for Cancer Research called on the U.S. Food and Drug Administration (FDA) to conduct new research into the health effects of vaping, and use tobacco tax revenues to help fund studies. The groups also included a lengthy list of recommended actions by state and government agencies, according to Science Insider, which viewed the statement.

Two of the largest cancer science and treatment groups in the United States are calling on the government to start regulating electronic nicotine delivery systems, better known as e-cigarettes, and increase research on the health consequences of vaping as the popularity of e-cigarettes continue to rise.
“While e-cigarettes may reduce smoking rates and attendant adverse health risks, we will not know for sure until these products are researched and regulated,” said Peter Paul Yu, president of the 35,000-member American Society of Clinical Oncology, in a statement obtained by Science Insider. “We are concerned that e-cigarettes may encourage nonsmokers, particularly children, to start smoking and develop nicotine addiction.” The American Association for Cancer Research, which is 33,000 members strong, echoed Yu’s sentiments.
The joint statement calls for more research into the health effects of e-cigarettes and using tobacco tax incomes to help fund studies. The groups want e-cigarette manufacturers to register their products with the U.S. Food and Drug Administration (FDA) to identify the chemicals and amounts of nicotine found in various brands, and to agree to help end teen vaping, according to Science Insider.
A study published in PLOS One suggests that electronic cigarettes can cause a harmful immune response and increase the risk of lung infections. The study was led by Dr. Qun Wu, a lung disease researcher at National Jewish Health in Denver.
The researchers conducted the study by exposing healthy cells lining the lungs, called epithelial cells, and exposing them to e-cigarette vapor in the laboratory. Exposure to vapor caused an increase in IL-6 proteins, which trigger inflammation, within 10 minutes. This harmful immune response lasted up to 48 hours later.
“Epithelial cells are the first line of defence in our airways,” Wu said, according to Health24. “They protect our bodies from anything dangerous we might inhale. Even without nicotine, this liquid can hurt your epithelial defence system and you will be more likely to get sick.”
“We have provided strong evidence that the liquid used in e-cigarettes, whether it contains nicotine or not, has negative effects on the airways and on the lungs. The problem is, these products aren’t regulated and there are no standards to control how much nicotine or other chemicals they contain. I think e-cigarettes could prove dangerous, especially with long-term consumption,” the authors wrote.
Co-author Dr. Hong Wei Chu, director of the Basic Science Section at National Jewish Health said “The cells showed a strong pro-inflammatory response and the risk of viral infection in those cells rose significantly.” The vapor made the cells more susceptible to infection by rhinovirus, the virus primarily responsible for causing the common cold.
The popularity of e-cigarettes has risen considerably in recent years. Less than 2 percent of adults in the United States had tried e-cigarettes in 2010 but by last year this figure increased 620 percent to 40 million. E-cigarettes are marketed as being a healthier than regular cigarettes and a potential cessation aid, but a growing body of research suggests the risks are greater than advertised.
A U.S. District Court judge recently denied a motion by Johnson & Johnson (J&J) and Imerys Talc America, Inc., fka Luzenac America, Inc. to dismiss a lawsuit filed by the widower of a woman who died of ovarian cancer. The man alleges his late wife’s cancer was caused by the use of Johnson & Johnson Baby Powder and Shower to Shower (containing talc mined and sold by Imerys) in the genital area.
