A 2025 randomized controlled trial in Nutrients by Sharif et al. showed those who drank tocotrienols experienced better psychological well-being, lowered markers of oxidative stress, increased antioxidant enzymes, and improved genomic stability.

A 2025 UCLA pilot study led by Sanjay Mohanty found that a single piece of chewing gum can release between 100 to over 600 microplastic particles per gram, which means a large stick may shed up to 3,000 fragments into your saliva during chewing.

A 2013 review from the University of Toronto (Frontiers in Genetics) reveals how smoking alters your genes—not by mutation, but by changing their “on/off” settings via DNA methylation. This epigenetic shift can silence protective genes or activate harmful ones, linking smoking to cancer, heart disease, obesity, and even long-term issues in children exposed in the womb.

A 2025 review in Nutrients links regular sugar-sweetened beverage (SSB) consumption to poorer sperm health—lower count, reduced motility, and increased DNA damage. Oxidative stress, hormonal disruption, and obesity may be to blame.
