Just when New Years resolutions on weight loss are in full swing comes a large new study that suggests being pudgy may actually help us live longer, even as it finds being extremely obese increases our risk of premature death.
While the study has already spurred plenty of controversy among the experts, when it comes to cancer one point remains clear: having excess body fat increases the risk of seven types of cancers, including colorectal, post-menopausal breast, and endometrial. The more people weigh, the higher the risk.
“This study raises interesting questions about obesity and all-cause mortality, but for cancer risk the evidence is clear,” said AICR Director of Research Susan Higginbotham, PhD, MPH, RD. “Our expert report and its updates show that body fatness increases the risk of several common kinds of cancer.”
The study was published today in the Journal of the American Medical Association. Continue reading
Two new studies strengthen the link between sugary drinks leading to weight gain and obesity. The research adds powerful new evidence to AICR’s recommendation that people should avoid drinking sugary beverages to reduce cancer risk because what we weigh is important. Obesity links to increased risk of seven types of cancers.
The studies were released on Friday in the New England Journal of Medicine.
The new studies provide a strong case for the direct effect of sugary sodas on weight gain, regardless of diet and exercise. The studies were relatively long and experimental: In contrast, the vast majority of long-term studies on sugary beverages – and diet in general – are observational, meaning that researchers look at any link between what participants drink and their weight.
These experimental studies both focused on how sugary beverages affect the weight of children and adolescents.
The first study took place over two-years and included 224 overweight and obese adolescents who drank almost two sugary beverages a day. About half of the teens were asked to drink water, diet sodas, or other calorie-free beverages instead of their normal sugary drink. The other half continued to drink their sugary beverages as normal. Continue reading
America’s obesity epidemic stretches from coast to coast and encompasses every state, with twelve states having at least three of every ten residents obese, according to a new government survey.
Every state had at least 20 percent of its residents report they were obese, the latest Centers for Disease Control and Prevention (CDC) survey found. The estimates have severe implications for our country’s future cases of cancer, as well as heart disease and type 2 diabetes. Obesity increases the risk of seven types of cancer, including colorectal and postmenopausal breast.
The estimates come from an annual telephone CDC survey, called the Behavioral Risk Factor Surveillance System.
The South had the highest prevalence of adult obesity, with Mississippi at the top at 35 percent. Western states reported the lowest overall obesity prevalence with Colorado coming in at the bottom, still having 21 percent of its residents reporting they were obese.
This year, CDC made some changes to improve their data collection and analysis. For example, they called cell phones for the first time as well as landlines.
The updates mean you cannot compare this year’s estimates to those of previous years. But still, obesity rates remain high. A different CDC survey released earlier this year estimated that more than one-third of U.S. adults are obese. This survey included interviews, physical exams, and lab tests.
