Black Box meals: Lessons from five dietary intervention studies.

Black Box: “A complex system or device whose internal workings are hidden or not readily understood.” (From Oxford.)   Dietary intervention black boxes are those in which catering companies, institutional food preparers or even test subjects create meals whose sourcing, preparation, cooking, and serving details are mostly unknown and unguided by investigators. At best, food […]

Dosing of a single compound to establish causality in dietary interventions & enable clinically valid health decisions.

“Inconsistent and contradictory results from nutrition studies conducted by different investigators continue to emerge, in part because of the inherent variability of natural products, as well as the unknown and therefore uncontrolled variables in study populations and experimental designs.” — The Challenge of Reproducibility and Accuracy in Nutrition Research: Resources and Pitfalls Dietary studies are […]

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, […]
