The key to successful nutrition starts before you even begin cooking. A well-prepared grocery list helps avoid impulse buys and keeps you focused on foods that heal rather than harm.

Shop the perimeter of the store where fresh produce, meat, and dairy alternatives are usually found. Be wary of long shelf-life items in the middle aisles. If you shop online, read labels carefully and set filters to avoid common problem ingredients.

Farmer’s markets, co-ops, and CSA boxes can provide fresh, seasonal produce with fewer pesticides and less packaging. Buying organic is ideal for foods on the “Dirty Dozen” list, especially when dealing with toxin overload.

When shopping for proteins, opt for grass-fed, pasture-raised, or wild-caught when possible. For pantry staples, look for BPA-free cans, gluten-free whole grains, and oils stored in dark glass bottles.
