Cooking oil touches almost every meal in an Indian kitchen. From the morning tadka to the evening sabzi, it is one of the most consumed ingredients in the household. Yet most families pick their oil based on price and habit rather than what the oil actually contains. When you compare cold pressed oil vs refined oil, the differences go well beyond taste and colour. Cold pressed oils retain the natural vitamins, antioxidants, and fatty acids that refining strips away. This guide explains what those differences mean for your family's health, which nutrients survive each process, and how to make the switch practical.
How Cold Pressed and Refined Oils Are Made
Understanding why cold pressed oil is better starts with understanding how each type reaches your kitchen.
Cold pressed oil is extracted by mechanically crushing oilseeds at low temperatures, typically between 30°C and 50°C. No chemical solvents, bleaching agents, or deodorising steps are involved. The oil retains its natural colour, aroma, and the full range of nutrients present in the original seed. Indic Wisdom's wood-pressed cooking oils use traditional Lakdi Ghani churners that keep temperatures between 30°C and 40°C during extraction.
Refined oil follows a multi-stage industrial process. After an initial press, the oil is treated with hexane (a chemical solvent) to maximise yield. It then passes through degumming, neutralisation with sodium hydroxide, bleaching with clay, and deodorisation at temperatures often exceeding 230°C. Each step removes compounds that affect colour, taste, and shelf life. It also removes compounds that affect nutrition.
The result: refined oil is pale, odourless, and long-lasting on the shelf. Cold pressed oil is darker, more flavourful, and nutritionally richer.
What Refining Removes: The Nutrient Comparison
The question "is cold pressed oil good for health" is really a question about what survives the extraction process.
A 2026 systematic review published in Frontiers in Nutrition examined the nutritional and pharmacological properties of cold pressed oils across multiple studies. The review found that cold pressed oils have a distinct nutritional advantage over refined oils due to the preservation of unsaponifiable matter, a fraction rich in tocopherols (vitamin E), phytosterols, and phenolic compounds. The refining process, particularly bleaching and deodorisation, was shown to degrade these heat-sensitive nutrients significantly (Frontiers in Nutrition, 2026).
Here is how the key nutrients compare:
| Nutrient | Cold Pressed Oil | Refined Oil |
|---|---|---|
| Vitamin E (tocopherols) |
Up to 90% retention | 30 to 70% lost during refining |
| Polyphenols | Retained | Up to 88% lost (varies by oil) |
| Phytosterols | Present | Partially removed |
| Natural aroma and flavour |
Retained | Stripped during deodorisation |
| Trans fats | None | May form during high-heat deodorisation |
| Chemical solvent residues |
None | Trace hexane may remain |
| Shelf life | Shorter (2 to 3 months after opening) |
Longer (6+ months) |
The fatty acid ratios (MUFA, PUFA, saturated fat) remain broadly similar between cold pressed and refined versions of the same oil. The difference lies in the micronutrients and bioactive compounds that cold pressing preserves and refining destroys.
Five Health Benefits of Switching to Cold Pressed Oil
1. Better Antioxidant Protection
Cold pressed oils retain natural tocopherols and polyphenols, both of which function as antioxidants in the body. These compounds help neutralise free radicals, reducing oxidative stress that is linked to chronic conditions. A 2023 study published in Nutrients confirmed that cold-pressed oils are rich sources of alpha-tocopherol, with some varieties providing a significant portion of the recommended daily intake of vitamin E from just a few tablespoons (Wroniak et al., Nutrients, 2023).
Refined oils lose most of these antioxidants during bleaching and deodorisation, leaving behind calories without the protective compounds.
2. No Chemical Residues
Refined oils are extracted using hexane, a petroleum-derived solvent. While most hexane is removed during processing, trace amounts can remain. Cold pressed oils use no chemical solvents at any stage. For families concerned about what goes into their food beyond the ingredient list, this is a straightforward advantage.
3. Zero Trans Fat Formation
When oils are heated above 200°C during the deodorisation stage of refining, some unsaturated fatty acids can convert into trans fats. Trans fats raise LDL cholesterol and lower HDL cholesterol, increasing cardiovascular risk. Cold pressing stays well below these temperatures, so the natural fatty acid structure remains intact without any trans fat formation.
4. Reduced Harmful Aldehyde Production During Cooking
A 2022 review by Grootveld in Frontiers in Nutrition found that oils high in polyunsaturated fats (like refined sunflower oil) produced substantially more toxic aldehydes during sustained frying than oils with more stable fatty acid compositions. Cold pressed oils rich in monounsaturated fats, such as groundnut oil, showed better oxidative stability during cooking, producing fewer harmful breakdown products at typical Indian frying temperatures (Grootveld, Front. Nutr., 2022).
5. Improved Flavour and Natural Portion Control
This benefit is practical rather than clinical. Cold-pressed oils carry the natural taste of their source seed: a nutty warmth from groundnut, a sharp pungency from mustard, a subtle sweetness from coconut. This richer flavour means you often need less oil to achieve the same depth of taste. Refined oil, being flavourless, tends to be used more generously because it contributes nothing to the dish beyond fat.
For even more precise portion control, NAVA Wood-Pressed Oil Sprays let you use the same pure cold pressed oil in a spray format, reducing consumption by up to 30% per meal.

Making the Switch: Practical Tips
Switching from refined to cold pressed oil does not require a kitchen overhaul. A few adjustments make the transition smooth.
Start with your primary cooking oil: If your family currently uses refined sunflower or soybean oil, swap it for cold pressed groundnut oil. Groundnut oil has a mild, versatile flavour that works across nearly every Indian dish and a MUFA-rich profile that offers good heat stability.
Rotate two to three oils through the week: ICMR recommends using more than one type of cooking oil to ensure a balanced fatty acid intake. A practical rotation: groundnut oil for everyday cooking, mustard oil for dal and tadka, and coconut oil for South Indian dishes.
Cook on medium heat: Cold-pressed oils have slightly lower smoke points than their refined counterparts. For home cooking, this rarely matters since most Indian cooking (tadka, sautéing, shallow frying, home deep frying) happens between 130°C and 180°C. Keep the flame at medium to medium-high rather than maximum.
Store properly: Cold pressed oils are more sensitive to light and heat because the natural compounds that refining strips out are also the ones that make oil go rancid when exposed to air. Keep the bottle sealed, in a cool dark spot, and use within two to three months of opening.
Use sprays for light applications: For greasing a tawa, brushing rotis, or a quick tadka, NAVA Oil Sprays deliver the same wood-pressed oil with less waste.
Beyond Cooking Oil: Building a Cleaner Kitchen
Switching oils is one part of a broader shift toward less-processed food. Indic Wisdom's range covers several adjacent categories:
- Natural sweeteners like jaggery powder and khandsari replace chemically refined white sugar
- Protein Shakti, a plant-based protein powder, adds nutrition to everyday atta, dal, and smoothies without artificial ingredients
- Speciality oils for hair and skin wellness offer non-cooking uses for cold-pressed oils
Each product follows the same principle: minimal processing, maximum nutrient retention, zero chemical additives.
One Change, Compounding Returns
The health benefits of switching to cold pressed oil are not dramatic overnight. They compound quietly over months and years: better antioxidant intake, fewer chemical residues, a more favourable fatty acid profile, and a kitchen that runs on real flavour rather than industrial processing. The switch does not cost much more, does not require new recipes, and does not change how your food tastes (it improves it).

Frequently Asked Questions
Is cold pressed oil good for health?
Yes. Cold pressed oil retains natural antioxidants (vitamin E, polyphenols), phytosterols, and the complete fatty acid profile of the source seed. A 2026 systematic review in Frontiers in Nutrition confirmed that cold pressing preserves bioactive compounds that refining, bleaching, and deodorisation destroy. These compounds support cardiovascular health, reduce oxidative stress, and aid digestion.
Why is cold pressed oil better than refined oil?
Cold pressed oil preserves nutrients that the refining process removes. Refining strips up to 90% of natural vitamin E, up to 88% of polyphenols, and can introduce trace chemical residues from solvent extraction. Cold pressing uses no chemicals, no high heat, and no bleaching, resulting in an oil that delivers nutrition alongside calories rather than calories alone.
Can I use cold pressed oil for everyday Indian cooking?
Yes. Most home cooking in Indian kitchens happens between 130°C and 180°C, well within the smoke point range of cold pressed groundnut oil (160 to 180°C), mustard oil (150 to 180°C), sesame oil (160 to 177°C), and coconut oil (175 to 200°C). Keep the flame at medium to medium-high and avoid reusing frying oil more than once.
Does cold pressed oil cost much more than refined oil?
Cold pressed oil is typically 20 to 40% more expensive than refined oil per litre. However, because cold pressed oils carry more flavour, many families find they use less per dish. Using oil sprays for light applications further reduces consumption. The marginal cost difference is modest relative to the nutritional gain.
What is the difference between cold pressed oil and wood pressed oil?
Wood-pressed oil is a form of cold-pressed oil where the extraction is done using traditional wooden churners (Lakdi Ghani). The wooden pestle generates even less friction heat than metal expeller presses, keeping temperatures between 30°C and 40°C. Indic Wisdom's oils are wood-pressed, which is the most traditional and nutrient-preserving method of cold pressing.
