As a bioscientist studying aging, I believe cooking most of your meals at home is the simplest, high-impact dietary habit you can adopt for healthy aging.

It naturally shifts you towards single-ingredient, whole foods, and away from refined oils, added sugars, excess sodium, and the long list of additives common in ultra-processed foods and ready meals.

But even people who eat “clean” often miss a key layer: micronutrient adequacy.

Micronutrients = vitamins + minerals your body needs to:

  • build, protect, and repair cells

  • maintain healthy blood vessels

  • support immune function

  • regulate which genes are turned on or off

They’re required in small amounts, but their impact at the molecular level is huge.

So today, we’ll cover which ones matter most, and how to meet your needs without having to spend hundreds on supplements.
