Budget cuts have shifted nutrition research funding from government to private industries, leading to biases. Primary research, traditionally NIH-funded, is now less common. Applied research, often funded by pharma and food industries, can justify supplements or show harm in certain foods. Public health research, ideally government-funded, also sees private industry involvement. Clinical research, primarily pharma-funded, tests medications with variability complicating results. Pharmacological research focuses on managing health markers for long-term profitability. Bias in research includes funding bias, myth bias, scholarly pride bias, publication bias, media bias, government bias, and other conflicts of interest. Understanding these biases is crucial for scrutinizing research conclusions.
