18 Everyday Produce Items You Must Peel or Avoid

13. Cucumbers — Peel if waxed; otherwise wash and enjoy

Peel if the cucumber feels waxy or if you’re concerned about residues; wash otherwise. Many conventional cucumbers receive a thin wax coating that extends shelf life and can trap surface residues. Run them under warm water and rub with a cloth or a brush; if the skin still appears shiny or you prefer to avoid any possible coating, a quick peel solves the issue and keeps the interior crisp and refreshing. English cucumbers sometimes come wrapped in plastic and may be less waxed, making them easier to wash and eat unpeeled. For older adults, peeled cucumber slices are gentler on teeth and easier to digest, and prepping a small container of slices in advance makes a healthy snack handy without much daily effort.

14. Carrots — Scrub Thoroughly to Remove Soil Residues

Carrots are root vegetables that grow directly in the soil, which often contains systemic pesticides and can hold onto soil-bound contaminants. Since peeling removes many nutrients and fiber, the highest return on effort is a thorough scrub. Use a stiff nylon brush under running water to vigorously remove soil particles and the outermost layer of the skin. If you find the skin tough or heavily blemished, a light scrape with a vegetable peeler or knife is a low-waste compromise. For older adults, batch-scrubbing a week's supply and storing them in an airtight container in the refrigerator makes healthy snacking immediate and low-fuss.
