What Oil to Use When?
Share
Last week, a customer named Meera walked into my clinic looking genuinely frustrated.
She said,
“Every brand says their oil is the BEST. Cold-pressed, wood-pressed, extra virgin, refined… I don’t know what to trust anymore!”
I told her what I tell every family:
No single oil can do every job.
Each oil has its own personality—and its own perfect role in your kitchen.
Once Meera understood this, everything became easier for her.
Let me walk you through the same guide.
1. High-Heat Heroes
(for deep frying, tadka, stir-fry)**
These oils stay stable at high temperatures and don’t break down easily.
⭐ Groundnut Oil (Cold-Pressed/Wood-Pressed) — The Reliable All-Rounder
This is the first change I made in Meera’s kitchen.
Perfect for: frying, tawa cooking, tadka
Benefits: rich in heart-friendly monounsaturated fats
Wood-pressed version has better aroma & retains natural antioxidants
⭐ Mustard Oil (Cold-Pressed/Kachi Ghani) — The Traditional Power
Perfect for: tadka, sautéing, pickles
Benefits: naturally anti-inflammatory
Ideal for North & East Indian dishes
Wood-pressed mustard oil has a stronger, authentic flavour
⭐ Coconut Oil — The Coastal Strength
Meera grew up in Kerala, but stopped using coconut oil due to myths.
It was my job to reassure her.
Perfect for: medium-to-high heat cooking
Benefits: contains MCTs → quick energy
Excellent for South Indian curries and coastal dishes
Virgin coconut oil is great for light sautéing or finishing dishes
2. Medium-Heat Stars
(for sabzi, dal, daily cooking)
⭐ Sesame Oil (Cold-Pressed/Gingelly/Til) — The Flavor Boost
Perfect for: stir-fry, sabzi, tadka
Benefits: rich in antioxidants & healthy fats
Wood-pressed sesame oil adds a deep, earthy aroma
⭐ Cold-Pressed/ Wood-Pressed Varieties (Groundnut • Mustard • Sesame)
These oils are extracted with minimal heat and no chemicals.
Benefits: retain vitamin E, natural antioxidants & plant compounds
Best for: daily medium-heat cooking
Flavour is richer and more authentic
3. Low-Heat & Raw-Use Oils
(for salads, dips, and drizzling)
⭐ Extra Virgin Olive Oil — The Smooth Operator
Perfect for: salads, hummus, dressings
Benefits: supports heart health
Not suitable for frying
⭐ Flaxseed Oil — The Omega-3 Powerhouse
Perfect for: smoothies, drizzling on salads
Benefits: excellent for heart & hormone balance
Never heat this oil
⭐ Walnut Oil — The Brain Booster
Perfect for: cold dishes
Benefits: supports brain & nerve function
4. The Golden Rule: Use Oil Based on Cooking Method
This is the advice that made everything click for Meera:
High heat → Groundnut, Mustard, Coconut
Medium heat → Sesame, Cold-pressed oils
Raw use → Olive (extra virgin), Flaxseed, Walnut
This simple switch improved her digestion, skin health, energy levels—and her cooking tasted better too.
5. Why Cold-Pressed / Wood-Pressed Oils Are Worth the Hype
I explained to Meera why these oils are gaining popularity again:
✔ Minimal processing → more nutrients retained
✔ No chemicals or high-heat refining
✔ Authentic aroma and natural flavour
✔ Higher presence of antioxidants
✔ Better for overall health when used correctly
But remember:
Cold-pressed doesn’t mean “use for everything.”
Their smoke points vary—so choose based on cooking style.
