🫒 Plant-Based Fats: Refined or Unrefined — What to Look For

The same oil can be "alive" or "dead" — it all depends on processing

In the store, two identical-looking oils stand side by side, but one is twice as expensive. The difference is in refining. Let's look at how they differ and what to buy.

🔬 The core question

Refining is cleaning oil from impurities, taste and smell. It makes the oil clear and stable for frying, but takes away some nutrients.

  • Cleaning from impurities.
  • Removes taste and smell.
  • Clarity.
  • Frying stability.
Why it matters: processing decides whether nutrients remain.

🌱 Unrefined oil

Unrefined oil is minimally processed. It has more vitamins and antioxidants, but it doesn't tolerate strong frying.

  • Minimal processing.
  • More vitamins.
  • More antioxidants.
  • Avoids frying.
Data: extra-virgin olive oil is the "gold standard" of unrefined oils.

🏭 Refined oil

Refined oil is cleaned of impurities. It keeps longer and suits frying, but loses some nutrients.

  • Cleaned of impurities.
  • Keeps long.
  • Suits frying.
  • Loses nutrients.
Important: refined is convenient, but not why we eat oil.
