In a new analysis, scientists suggest combining different diet-tracking methods — from wearable cameras to dietary biomarkers — to paint a more reliable picture of what people eat and drink, rather than focusing on a single tool. Accurately capturing these trends has been one of the biggest challenges in nutrition research. The researchers stress that traditional self‑reported food diaries have often relied on memory and guesswork, placing a heavy time burden on participants. These limitations have made it difficult for researchers and policymakers to definitively link certain diets to health outcomes.
