Ultra-processed foods affect sperm quality and metabolism even without extra calories

A controlled crossover trial in Cell Metabolism found that ultra-processed foods increase weight, fat mass, LDL:HDL cholesterol, and alter reproductive hormones in men, with some effects independent of calorie load. These diets also showed trends toward reduced sperm motility, shifts in pollutants, and transient inflammatory responses, highlighting risks beyond excess calories.

Research examines how cancer may invalidate forensic age-estimation tools

Patients with solid tumors, including breast and lung cancers, showed only slightly less accurate results. In contrast, individuals with blood cancers, particularly chronic lymphocytic leukemia (CLL) and acute myeloid leukemia (AML), sometimes had large errors, with ages overestimated by as much as 50 years.

Early puberty and childbirth tied to accelerated aging and higher disease risk

Reproductive timing matters when it comes to aging and age-related disease. In a study now online at eLife¸ Buck researchers determine that girls who go through puberty (the onset of menstruation) before the age of 11 or women who give birth before the age of 21 have double the risk of developing type 2 diabetes, heart failure and obesity and quadruple the risk of developing severe metabolic disorders.
