A 62-year-old woman in Monroe, Louisiana is about to get access to a $2.26 million food-as-medicine program funded by her local government. The goal is preventing chronic disease before it starts. That is a genuinely good idea. The problem is what happens when people hear "food is medicine" and decide to stop taking their actual medicine.
The food-as-medicine movement has real science behind it. Diet quality is one of the strongest predictors of type 2 diabetes, heart disease, and certain cancers. Eating more vegetables, fewer processed foods, and less added sugar does measurable things to blood pressure, blood sugar, and inflammation. Nobody serious disputes this.
But the movement has a messaging problem. When advocates say food is medicine, some people hear: food instead of medicine. Those are completely different claims, and conflating them causes real harm.
The Right Tool for the Right Moment
If you have prediabetes and your doctor says your A1C is 5.8, changing what you eat can absolutely bring that number down. Add a cup of lentils to dinner 4 nights a week. Swap the afternoon chips for an apple and a handful of almonds. Walk for 20 minutes after your biggest meal. These are not dramatic changes, and they work. Food is doing real medical work there.
If your A1C is 9.2 and you have had type 2 diabetes for 6 years, food still matters. But telling that person to skip metformin and eat more kale is not bold thinking. It is dangerous advice dressed up as empowerment. The disease has progressed past the point where diet alone can manage it safely.
The honest version of this conversation is about timing. Food works best as prevention and as early-stage support. Drugs work best when the body is already in crisis. Treating those two situations as interchangeable is where the movement loses me.
What the Industry Gets Wrong
Mark Hyman, one of the loudest voices in functional medicine, has built a career arguing that food can replace most pharmaceuticals for most people. He is not entirely wrong about diet's power. He is wrong about the "replace" part, and his framing gives people permission to make decisions their doctors would not sanction.
To be fair: conventional medicine has its own blind spots here. Plenty of doctors prescribe statins without ever asking a patient what they eat for breakfast. The food-as-medicine crowd is right that diet gets underused as a clinical tool. That frustration is legitimate.
But the answer to medicine ignoring food is not to ignore medicine. It is to use both.
Here is what that actually looks like. You have high blood pressure. Your doctor prescribes lisinopril. You also start cooking with less salt, eating more potassium-rich foods like sweet potatoes and bananas, and walking 30 minutes most days. Six months later, your blood pressure is well-controlled. Maybe your doctor lowers your dose. Maybe not. Either way, you are healthier than if you had done only one of those things.
That is the version of food as medicine worth fighting for: diet as a serious clinical tool that works alongside drugs, not instead of them. Hospitals and insurers should cover medically tailored meals for people managing chronic illness. Doctors should ask about diet at every appointment, not just when someone is already sick. Community programs like the one in Monroe should get funded everywhere, not just in parishes with the right political connections.
Eat real food. Take your medication. These are not competing instructions. The people who need to hear that most are the ones already convinced they have to choose.
