#HeavyMetals

A new warning from Harvard-affiliated medical experts and recent research has raised urgent concerns over the safety of commercially available protein powders, drawing attention to potentially hazardous contaminants in products widely consumed by fitness enthusiasts, athletes, and health-conscious Thais. According to reviews by researchers and reports by advocacy groups such as the Clean Label Project, many popular protein powders contain significant levels of heavy metals, plastic-derived chemicals, and other toxins—a finding that threatens to upend perceptions of these supplements as inherently “healthy” choices for those pursuing muscle gain or dietary supplementation [Harvard Health][LADbible].

For generations, water spinach—known locally as “pak boong”—has been a staple green vegetable in Thai cuisine, cropping up in everything from fiery stir-fries to refreshing soups. Across Southeast Asia, its common names include morning glory and Ipomoea aquatica. While praised for its affordability, taste, and nutritional value, recent scientific studies reveal both notable health benefits and underappreciated risks associated with this aquatic vegetable. Understanding these factors can help Thai consumers make informed decisions and enjoy water spinach as part of a healthy diet.

A recent US-based investigation has rocked the dental care industry, with new research revealing that the majority of toothpaste brands—some specifically marketed for children or as “green” alternatives—are contaminated with toxic heavy metals, including lead, arsenic, mercury, and cadmium. The findings, released in April 2025, have raised serious public health concerns for families worldwide, including in Thailand, where toothpaste is a staple in daily hygiene routines and global brands are widely used.
