Eating burgers over broccoli may not cause you to have cancer, but if your diet leads to obesity, there’s more cause for concern. Many connections between specific foods and cancer prevention have been called into question in recent years, according to a New York Times article published earlier this week. Controlling obesity, on the other hand, appears to be more important.
Obesity has been associated with a higher risk for a variety of cancers, including cancers of the colon, esophagus, gallbladder, kidney, pancreas, uterus and breast, according to the National Cancer Institute (NCI). Around one in four new cancers in men and one in seven new cancers in women were attributed to obesity in 2007, according to one study cited by the NCI.
Recent reports suggest more connections between various cancers and obesity. In March, a USA Today article reported findings associating excess weight with ovarian cancer for the first time. This month, LiveScience cited another study connecting obesity to a specific type of breast cancer.
The benefits of a healthy weight are greater for reducing the risk of diseases such as diabetes and heart disease, medical oncologist Alexi Wright told USA Today. The NCI also notes that much of the evidence for the connection between obesity and cancer comes from observational studies, meaning it’s harder to tell whether other factors are to blame for cancer development.
Nonetheless, if you’re hoping to ward off the disease, you might be better off focusing on staying fit rather than eating a specific “superfood.”
