Here is a practical, evidence-backed breakdown of the best oils to eat and cook with:
Best Oils to Eat (Ranked by Overall Health Value)
1. Extra Virgin Olive Oil (EVOO) - Top Pick
- Rich in: Monounsaturated fats (oleic acid, ~73%), polyphenols, vitamin E
- Benefits: Strongly linked to reduced cardiovascular disease risk, lower LDL cholesterol, anti-inflammatory effects. The American Heart Association ranks it among the best heart-healthy oils
- Smoke point: ~190-210°C (fine for sautéing, roasting, dressings, drizzling)
- A 2024 umbrella review [PMID 39053603] confirmed vegetable oils including olive oil show favorable effects on cardiometabolic health
- Best use: Salad dressings, low-to-medium heat cooking, drizzling on food
2. Avocado Oil
- Rich in: Monounsaturated fats (~70%), vitamin E, lutein
- Smoke point: ~270°C - one of the highest of any cooking oil
- Benefits: Heart-healthy fat profile similar to olive oil; ideal for high-heat cooking like grilling, frying, and searing
- Best use: High-heat cooking, stir-frying, grilling
3. Canola Oil
- Rich in: Monounsaturated fats, omega-3 ALA, low saturated fat (~7%)
- A 2023 meta-analysis (PMID 35866510) found canola oil comparable to olive oil for improving serum lipid profiles
- Best use: Everyday baking and frying - neutral flavor, affordable
4. Flaxseed Oil
- Rich in: Omega-3 ALA (plant-based), highest of any oil
- Smoke point: Very low - NOT suitable for cooking
- WebMD notes it may support heart health and lower blood pressure
- Best use: Salad dressings, smoothies, drizzled cold over food only
5. Walnut Oil
- Rich in: Omega-3 and omega-6 polyunsaturated fats, antioxidants
- Low smoke point, best used cold
- Best use: Salad dressings, dips, finishing drizzle
Oils to Use in Moderation
| Oil | Issue |
|---|---|
| Coconut oil | ~90% saturated fat - fine occasionally, but AHA advises limiting it |
| Palm oil | High saturated fat, environmental concerns |
| Butter/ghee | Saturated fat; not technically "oil" but common cooking fat |
Oils to Limit or Avoid (High-Heat Processed)
- Highly refined seed oils (corn, soybean, generic "vegetable oil"): Very high in omega-6 linoleic acid; the modern Western diet already has too much omega-6 relative to omega-3, which promotes inflammation
- Partially hydrogenated oils: Contain trans fats - harmful to cardiovascular health; mostly phased out but still worth checking labels
Quick Guide by Use Case
| Purpose | Best Oil |
|---|---|
| Raw / drizzling / dressings | Extra virgin olive oil, walnut oil, flaxseed oil |
| Everyday cooking (medium heat) | Olive oil, canola oil |
| High-heat frying / grilling | Avocado oil, refined olive oil |
| Baking | Canola oil, avocado oil |
| Flavor / finishing | EVOO, sesame oil (small amounts) |
Bottom line: Extra virgin olive oil is the most evidence-backed oil for daily eating and cooking. Avocado oil is the best choice for high-heat cooking. Minimize highly refined seed oils and limit saturated fat sources like coconut oil.

Here's a detailed head-to-head on both oils:
Sunflower Oil vs Groundnut (Peanut) Oil
Fat Composition (per 100g)
| Fat Type | Sunflower Oil | Groundnut Oil |
|---|---|---|
| Monounsaturated (MUFA) | ~19-20g | ~46g |
| Polyunsaturated (PUFA) | ~65g | ~32g |
| Saturated fat | ~10g | ~17g |
| Omega-3 | Negligible | Negligible |
| Vitamin E | Very high | Moderate |
Sunflower Oil
Pros:
- Very high in vitamin E (antioxidant) - one of the richest sources among cooking oils
- Light flavor, affordable, widely available
- High smoke point (~230°C refined) - good for frying
Cons:
- Extremely high in omega-6 linoleic acid (~65%) - the main problem
- Zero omega-3, so it worsens your omega-6 to omega-3 ratio when used heavily
- Excess omega-6 from refined seed oils is linked to low-grade chronic inflammation when not balanced with omega-3
- Refined versions are heavily processed
Verdict: Fine in small amounts, but using it as your primary cooking oil every day is not ideal because of the omega-6 overload.
Groundnut (Peanut) Oil
Pros:
- Much higher MUFA content (~46g) - 2.4x more than sunflower oil - MUFAs actively help lower LDL cholesterol
- Better overall fat balance compared to sunflower
- High smoke point (~230°C refined) - excellent for deep frying, stir-frying
- Contains resveratrol (antioxidant also found in red wine)
- Distinct flavor adds depth to Indian cooking
Cons:
- Higher saturated fat than sunflower (~17g vs ~10g)
- Also lacks omega-3
- Allergy risk for people with peanut allergies
- Refined versions lose some nutritional value - cold-pressed / kachi ghani groundnut oil retains far more nutrients
Verdict: Better than sunflower oil for everyday cooking due to its higher MUFA content and more balanced fat profile.
Which Should You Use?
| Situation | Recommendation |
|---|---|
| Everyday cooking (Indian meals) | Groundnut oil (cold-pressed ideally) |
| Deep frying | Either works; groundnut preferred for flavor |
| Salad dressings / raw use | Neither - use EVOO or flaxseed oil |
| If budget is tight | Groundnut > Sunflower |
| Avoiding all seed oils | Switch to EVOO or avocado oil |
The Key Takeaway
Groundnut oil > Sunflower oil for regular cooking - mainly because its MUFA content (similar to olive oil's benefit) is much higher, and MUFAs are clearly heart-protective.
Sunflower oil is not harmful in moderation, but its very high omega-6 content makes it a poor choice as a daily staple oil. If you're Indian and cooking with these oils daily, cold-pressed (kachi ghani) groundnut oil is the most practical and healthy choice among traditional options. Mustard oil (common in Bengali/North Indian cooking) is another strong option - it naturally has some omega-3 content.

Key Takeaways
Best for heart health: Olive oil, Avocado oil, Canola oil (highest evidence base)
Best for Indian/high-heat cooking: Avocado oil, Groundnut oil (cold-pressed), Mustard oil, Rice bran oil
Best omega-3 source (cold): Flaxseed oil (57% omega-3 - never heat it)
Worst for daily use: Sunflower, Corn, Soybean oils - very high omega-6, worsens omega-6:omega-3 imbalance
Avoid: Palm oil (health + environment), Partially hydrogenated/trans fat oils
Fat Type Quick Legend
- MUFA = Monounsaturated fat - heart-protective, stable at heat
- PUFA / Omega-6 = Polyunsaturated fat - healthy in moderation, but excess omega-6 promotes inflammation
- Omega-3 = Anti-inflammatory - most oils have almost none (eat fatty fish or flaxseed to compensate)
- Sat. Fat = Saturated fat - limit to <10% of daily calories per most guidelines
For daily cooking canola or groundnut
Both are solid choices. The short answer: canola wins on nutrition, groundnut wins on Indian cooking practicality.
Canola vs Groundnut for Daily Cooking
| Factor | Canola Oil | Groundnut Oil |
|---|---|---|
| MUFA | 62% | 46% |
| Omega-6 | 22% | 32% |
| Omega-3 | 10% | Trace |
| Saturated fat | 7% (lowest of any oil) | 17% |
| Smoke point | 200-230°C | 230°C |
| Flavor | Neutral | Mild nutty |
| Processing | Usually refined/GMO | Cold-pressed available |
| Price (India) | More expensive, less common | Cheap, widely available |
| Health rating | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ |
Why Canola Edges Ahead Nutritionally
- Only common cooking oil with meaningful omega-3 (10%) - this is rare and valuable since most Indian diets are already omega-3 deficient
- Lowest saturated fat of any oil (~7%)
- Higher MUFA than groundnut
- The omega-6 to omega-3 ratio is about 2:1 - nearly ideal (groundnut is ~80:1)
Why Groundnut is the Better Practical Choice for India
- Cold-pressed / kachi ghani groundnut oil is easy to find at any Indian grocery or mill
- Higher smoke point - handles the high heat of tadkas, deep frying, and Indian stir-frying better
- Natural flavor complements Indian dishes
- Significantly cheaper
- Cold-pressed version retains natural antioxidants and resveratrol
Verdict
| If you want... | Choose |
|---|---|
| Best nutritional profile | Canola |
| Best for Indian cooking style | Groundnut (cold-pressed) |
| Budget-friendly daily use | Groundnut |
| Omega-3 balance without eating fish | Canola |
Practical recommendation: Use cold-pressed groundnut oil for daily Indian cooking (tadka, frying, sabzi). Add a small amount of canola or flaxseed oil to salads/dals cold to get your omega-3 in. That combination gives you the best of both worlds without overhauling your cooking habits.
Healthy choice
Canola oil is the healthier choice, straight up.
Here's why in simple terms:
Why Canola Wins on Health
1. Omega-3 Content - the deciding factor
- Canola has 10% omega-3 - groundnut has almost zero
- Most people (especially in India) are already severely omega-3 deficient
- Using canola daily quietly corrects this imbalance with every meal - no supplements needed
2. Lowest Saturated Fat of Any Oil
- Canola: 7% saturated fat
- Groundnut: 17% saturated fat
- Less saturated fat = lower LDL (bad cholesterol) over time
3. Best Omega-6 : Omega-3 Ratio
- Canola = 2:1 (close to ideal)
- Groundnut = 80:1 (heavily skewed - promotes inflammation)
- This ratio matters more than any single fat type
4. Higher MUFA than Groundnut
- Canola 62% vs Groundnut 46% - both good, but canola leads
The One Catch with Canola
- Most canola sold in India is refined and may be GMO
- Look for cold-pressed / expeller-pressed canola if possible
- Refined canola is still nutritionally fine - refining removes flavor/odor but doesn't destroy the fat profile significantly
Bottom Line
For pure health - choose canola. It has omega-3, lowest sat. fat, best fat ratio, and strong heart-health evidence from multiple meta-analyses.
If canola is hard to find or expensive in your area, cold-pressed groundnut is the next best practical option - still a good oil, just not as nutritionally complete as canola.
