Résumé de Food Fix

In Food Fix, physician Mark Hyman argues that the global food system is the single largest driver of chronic disease, climate change, biodiversity loss, and economic inequality, and that fixing it is the most powerful lever for improving human and planetary health. Hyman, a functional medicine advocate and author of books like The Blood Sugar Solution, frames the problem as a set of interlocking crises he calls "big food" dysfunction: industrial agriculture subsidized by farm bills, ultra-processed products engineered for addiction, and food policy shaped by corporate lobbying rather than public health. The book is organized around the idea that food is medicine and that our current system creates "diabesity"—the linked epidemics of obesity and type 2 diabetes—along with heart disease, cancer, and dementia. Hyman traces how government subsidies make calorie-dense, nutrient-poor foods artificially cheap while real food becomes expensive, and how marketing targets children and communities of color. He examines the environmental cost of industrial meat production, monoculture farming, and food waste, tying them to deforestation, water scarcity, and greenhouse gas emissions. Hyman proposes solutions at multiple levels: policy changes such as reforming subsidies, taxing sugary drinks, and regulating food marketing; corporate responsibility in food production and retail; community-level interventions like food policy councils and urban farming; and individual steps including a "peg" framework for choosing food. He profiles real initiatives, such as community-supported agriculture and food-as-medicine programs, and cites research on the microbiome, epigenetics, and metabolic health. The book also includes a section on what readers can do personally and politically, emphasizing that food is a public good, not just a commodity. It is both a critique of the industrial food system and a call to action for systemic change.
