It feels obvious to me now that what I eat shapes how I feel and function, but I haven’t always thought about it that way. Looking back, I can see my own growth in understanding food as something that prevents problems rather than just tastes good. The shift happened gradually—noticing how alcohol hits me immediately, or how skipping oil and meat changes my energy and clarity. That direct feedback loop made the connection between food and medicine impossible to ignore. Resources like Issue No. 183: Food as Medicine help frame what I’ve been observing in my own life into something larger.
The barrier I see for people around me isn’t ignorance—it’s that default behaviors win every time. People know what’s healthy, but convenience and cost are the actual blockers. If something requires extra effort or money, most people won’t do it, no matter how good the health outcomes are. That’s not a willpower problem; it’s a friction problem. The Smart Economics of Eating Healthy captures this tension between what we know and what we actually do. Until eating well is as easy and affordable as eating poorly, the statistics won’t move much.
What puzzles me is why we’ve kept food and medicine in separate silos when the evidence is so clear that they’re interconnected. The issue isn’t really knowledge—85% of healthcare spending comes from diet-related diseases, and personalized meal prescriptions could theoretically save over $100 billion. The problem is that it’s unclear how you’d actually prescribe food or target it the way you would a drug, and there’s no financial incentive for the system to figure it out. Navigating the Gray Areas of Lifestyle Medicine: A Balanced Approach explores this friction between what works and what gets funded. Policy frameworks like those discussed in What Is ‘Food Is Medicine,’ Really? Policy Considerations On The Road To Health Care Coverage suggest we’re starting to ask the right questions, but implementation still lags.
For me to actually use something like personalized meal prescriptions, it has to solve the same two problems everyone faces: it has to be convenient and it has to be affordable. If I have to think about it, plan it, or spend extra money, I won’t stick with it—not because I don’t believe in it, but because I’m human. The framework exists at odphp.health.gov, but the real work is making it frictionless enough that people choose it by default. Redefining Mental Health: The Metabolic Perspective and Challenges in Healthcare reminds me that understanding the mechanism is just the first step; the bigger challenge is building systems people will actually use.
