Medical News Today : declared in Poor diet during teens, early adulthood may raise breast cancer risk

After skin cancer, breast cancer is the most common cancer among women in the United States. Researchers have associated an unhealthful diet in adolescence or early adulthood with greater risk of developing premenopausal breast cancer. A pro-inflammatory diet was not associated with the overall incidence of breast cancer or the risk of postmenopausal breast cancer, the team reports. The risk of developing premenopausal breast cancer may be higher for women who have a poor diet during adolescence and early adulthood, new research finds. "However, each woman's breast cancer risk is different based on numerous factors, including genetic predisposition, demographics, and lifestyle."

Walnut-enriched diet may improve sperm quality, animal research suggests

New animal research suggests eating a walnut-enriched diet may improve sperm quality by reducing lipid peroxidation, a process that can damage sperm cells. "Studies that look at the factors underlying sperm quality improvements are very valuable for advancing research on this important topic." Intrigued by these findings, published in 2012 in Biology of Reproduction, Martin-DeLeon set out to understand the mechanism involved in improved sperm quality with a walnut-enriched diet. Sperm motility (movement) and morphology (form) are markers of semen quality, which is a predictor of male fertility. Among the mice that consumed walnuts, fertile mice experienced a significant improvement in sperm motility and morphology and the infertile mice had a significant improvement in sperm morphology.


Diet inflammatory score was not associated with overall breast cancer incidence or postmenopausal breast cancer. "However, each woman's breast cancer risk is different based on numerous factors, including genetic predisposition, demographics, and lifestyle. Bottom Line: Women who consumed a diet as adolescents or young adults associated with chronic inflammation had a higher risk for premenopausal breast cancer compared with those whose adolescent and early adulthood diet was not associated with chronic inflammation. During 22 years of follow-up, 870 of the women who completed the high school food frequency questionnaire were diagnosed with premenopausal breast cancer and 490 were diagnosed with postmenopausal breast cancer. "Because breast cancer takes many years to arise, we were curious whether such a diet during the early phases of a woman's life is a risk factor for breast cancer," she said.
