Teen Girls' Poor Diet Raises Risks for Future Breast Cancer
For teen girls, eating a poor-quality diet may lead to weight gain, greater heart disease risk, and higher odds of developing breast cancer later in life. In a long-term study of more than 45,000 female nurses, 3 percent developed breast cancer over 20 years. Those in the top fifth bracket for inflammatory food consumption as teenagers had a 35 percent greater risk of developing breast cancer before menopause compared with those in the bottom fifth. Unhealthful foods such as sugary sodas, red and processed meats, and refined (rather than whole) grains may be more likely to cause inflammation, which can lead to cancer. Fish and vegetables such as leafy greens, however, are smart options.
