Leyla Weighs In: Sperm Quality and Diet–The Role of Ultra-Processed Foods

Nutritionist Leyla Muedin discusses the impact of ultra-processed food (UPF) consumption on sperm quality, referencing a study from the journal Human Reproduction. Findings indicate higher UPF intake is linked to lower sperm count, concentration, and motility in Spanish men. Leyla also explores a study on the effects of a lifelong vegetarian diet on male fertility in Loma Linda’s Blue Zone population. She emphasizes that ultra processed foods and higher body mass index (BMI) correlate with deteriorating sperm quality, suggesting whole foods as a healthier dietary choice to improve fertility.
