Read the label. Then, read it again.

I didn't become a label reader all at once. It happened slowly. Not from a single revelation, but from years of watching someone I loved lose his mind to a disease I couldn't stop but yet had to question.

My father had Alzheimer's, followed by late-stage pancreatic cancer. He was also a heavy smoker and a heavy drinker for much of his life. The research is increasingly clear that both significantly raise the risk of cognitive decline and neurological disease. Watching this all converge in one person…I couldn't just grieve the person I once knew. I had to understand why.

That research led me to Dr. David Perlmutter, a neurologist who has spent decades making the case that what we eat is quietly destroying our brains. I found him through his talks and interviews; hours of listening to him draw a direct line between the modern processed diet - the sugar, the refined carbohydrates, the gluten - and diseases including Alzheimer's and dementia. His core message is both uncomfortable and clarifying: the fate of your brain is not in your genes. It's in your food.

Dr. Mark Hyman calls it "inflammaging". The chronic, low-grade inflammation driven by ultra-processed foods that sits at the root of heart disease, diabetes, dementia, and cancer. But what struck me most in his work is the gut-brain axis: the understanding that the gut and the brain are in constant conversation with each other. Sixty to seventy percent of the immune system lives in the gut. When we feed it processed food, we disrupt the microbiome, trigger inflammation, and that inflammation? Travels straight to the brain. The gut isn't separate from how we think, feel, and remember. It's the foundation of it. There's a saying that runs through functional medicine that has stayed with me: genes load the gun, environment pulls the trigger. What we eat, drink, and absorb every day is the environment. We have more power over this than we've been led to believe.

So now I try to turn around everything I pick up. Every package, every snack, every sauce. If I can't pronounce it, it goes back on the shelf. Which, if I'm being honest, eliminates most of what's out there. It's pretty depressing once you see it. Most of what lines those shelves is garbage. Straight up garbage dressed up in pretty packaging. You just have to be willing to flip it over. I don't always get it right. Life is busy, kids are hungry, and sometimes convenience wins. But I'm more conscious than I was yesterday. And that, I've decided, is enough to keep going.

The kids have absorbed this completely, maybe too completely. At Costco, they are the first ones to spot it. They'll pick something up, flip it over, and announce loudly - Mom, it has red 40. Mom, it says natural flavors - while the man next to us has a gallon of canola oil and a family-sized box of Chex Mix sitting in his cart. I feel a flicker of self-consciousness every time. And then I feel grateful. Because they're paying attention.

At home, they pull tomatoes and strawberries straight from the garden and eat them before they even make it inside. No label. No ingredient list. Just the thing itself, warm from the sun, grown in soil they helped tend. That’s the dream, anyway.

Perlmutter writes that our lifestyle choices are fundamental, crucial even, in determining our brain's destiny. Hyman says there is no more powerful lever you can pull to change your biology than the food you eat. I believe both of them. Not just because I read it, but because I watched the alternative unfold in real time, over seven years, in my father.

Every time I flip a package over. Every time my child blurts out “it has palm oil!” in the middle of Costco. Every tomato eaten warm in the garden before anyone even thought to wash it. That is an act of love. For the body, for the brain, for all of us just trying to do a little better.
