Why a Dormitory Setting is Needed for Dietary Intervention Studies of Plastic-Derived Chemicals

Plastic contamination is inescapable. Plastic micro-and nanoparticles —  as well as the chemical compounds used to produce the polymers — are ubiquitous in the environment and present formidable confounding factors that make it impossible to establish causal relationships between a single chemical and measured human health outcomes. Well-designed scientific studies involve a “before and after” […]

Best practices — Herbs and Spices: Powerful in small amounts, precise measurement needed

See also: Best practices: Scale calibration Spices are at their most obvious as taste enhancers. No where is this more clearly illustrated than the results of a study that every mother would rank as a near-miracle — spices can induce high school students to like vegetables. At the foundational level, herbs and spices are well-tested […]

Best practices: Scale calibration

Use a set of gram weights to see how accurate your electronic scale is. Recognize that most commonly available sets of gram weights will vary in their own accuracy. However, a kitchen setting does not require ultra-precise measurements. This method eliminates wide discrepencies. After using a wide variety of solid weights and combinations of them, […]

Micro- and Nanoplastics: Health Implications

Microplastics are generally those fragments that are less than five millimeters in size. However, a single microplastic fragment rarely stays the same size.   Whether found on dry land, in steams and oceans — or in your mouth as you chew, swallow and digest — natural and biological forces relentlessly reduce microplastics in size. Eventually, […]

Best practices: De-waxing apples

There is no standard for the wax coatings used to preserve apples and other fruits and vegetables. Some studies indicate that the coatings are no longer simply carnuba-based, but are undisclosed compounds containing plastic polymers that may trap residues of pesticides and other chemicals. Given that these represent an unknown confounding factor, investigators decided to […]
