Can Ultra-Processed Foods Lead to Weight Gain and Harm Sperm Quality in Men?

Synopsis
Key Takeaways
- The consumption of ultra-processed foods can lead to significant weight gain.
- These foods disrupt hormonal balance, affecting sperm quality.
- Even moderate consumption poses health risks.
- Public awareness and revised nutritional guidelines are essential.
- Further research is needed to understand long-term effects.
New Delhi, Aug 30 (NationPress) A study reveals that even minimal consumption of ultra-processed foods can contribute to weight gain, hormonal imbalance, and diminished sperm quality in men. An international research team has found that individuals tend to gain more weight on an ultra-processed diet compared to a minimally processed one, even when caloric intake remains the same.
Published in the journal Cell Metabolism, the research indicates that a diet rich in ultra-processed foods can increase exposure to pollutants known to negatively impact sperm quality.
Lead author Jessica Preston from the University of Copenhagen's NNF Center for Basic Metabolic Research (CBMR) stated, “Our findings highlight that ultra-processed foods compromise our reproductive and metabolic health, even when consumed in moderation. This suggests that it is the processed nature of these foods that renders them harmful.”
To acquire comprehensive data, the team analyzed the health effects of unprocessed versus ultra-processed diets on the same individuals.
The study involved 43 men aged 20 to 35, who followed each diet for three weeks, with a three-month ‘washout’ period in between.
Participants were divided into two groups: one that began with the ultra-processed diet and one with the unprocessed diet. Some men received an additional 500 calories daily, while others consumed their regular caloric needs. Participants were unaware of which diet they were on.
Both diets contained identical amounts of calories, proteins, carbohydrates, and fats.
Men on the ultra-processed diet gained approximately 1 kg more fat mass compared to those on the unprocessed diet, irrespective of their calorie intake. Various other cardiovascular health markers also showed significant changes.
The researchers noted a concerning rise in the levels of the hormone-disrupting phthalate cxMINP, a substance found in plastics, among men consuming the ultra-processed diet. Participants on this diet also experienced lower testosterone and follicle-stimulating hormone levels, essential for sperm production.
Professor Romain Barrès from the University of Copenhagen commented, “We were astonished by the extent of bodily functions disrupted by ultra-processed foods, even in healthy young men. The long-term consequences are troubling and underscore the necessity to revise nutritional guidelines to better safeguard against chronic diseases.”
