Why Does Oil Choice Matter for an Athlete?
Not all oils are the same. Some are suitable for high temperatures (cooking), others must be used only cold (salads). For athletes, oil choice matters for several reasons: fatty acid profile affects inflammation and hormone production; smoke point determines whether the oil produces toxic compounds; and MCT oils are a quick energy source in endurance sports.
📊 Comparison of 8 Cooking Oils
| Oil | Smoke t° | Mono. | Poly. | Saturated | Omega-3 | Best Use |
|---|---|---|---|---|---|---|
| Olive (EV) | 160-190°C | 73% | 11% | 14% | 0.8% | Salads, low t° |
| Avocado | 270°C | 70% | 13% | 12% | 1% | Cooking, salads |
| Coconut (virgin) | 177°C | 6% | 2% | 92% | 0% | Cooking, MCT |
| MCT oil | 160°C | 0% | 0% | 100% | 0% | Sports nutrition |
| Flaxseed | 107°C | 18% | 73% | 9% | 53%! | COLD only! |
| Rapeseed | 204°C | 63% | 28% | 7% | 9% | Cooking, salads |
| Sunflower | 227°C | 20% | 69% | 11% | 0% | Cooking |
| Sesame | 210°C | 40% | 42% | 15% | 0.3% | Asian dishes |
🫒 Olive Oil (Extra Virgin) — The Antioxidant King
Extra Virgin olive oil (EVOO) is the cornerstone of the Mediterranean diet. It is rich in monounsaturated fats (73%) and polyphenols (oleocanthal, oleuropein). Oleocanthal acts similarly to ibuprofen — inhibits COX-1 and COX-2 enzymes, reducing inflammation.
- Anti-inflammatory effect: 50 ml of EVOO per day has an anti-inflammatory effect equivalent to 10% of an adult ibuprofen dose — naturally reducing post-workout inflammation.
- Heart health: Monounsaturated fats increase HDL ("good") cholesterol and reduce LDL, improving cardiovascular function — important for endurance athletes.
- Use: Only for cold dishes or low temperature (<180°C). NEVER fry over high heat — polyphenols break down and the oil becomes toxic.
🥑 Avocado Oil — The Universal Champion
Avocado oil has the highest smoke point (270°C) of all natural oils, making it excellent for frying, stewing and oven cooking. Its fatty acid profile is similar to olive oil, but without bitterness at high temperatures.
- High smoke t°: 270°C — the only oil suitable for high temperatures without polyphenol degradation. Ideal for steaks and roasting vegetables.
- Lutein: Avocado oil contains lutein — a carotenoid that protects the eyes from UV damage. Important for outdoor athletes.
- Versatility: Suitable both cold (salads) and hot (cooking) — if you want to have one oil in the kitchen, choose avocado.
🥥 MCT Oil — The Athlete's Energy Source
MCT (Medium Chain Triglycerides) oil is purified medium-chain fatty acids from coconut or palm oil. Unlike long-chain fats, MCTs are absorbed directly into the blood and quickly converted into ketones — an alternative energy source for the brain and muscles.
⚡ Fast Energy
MCTs are metabolized 4 times faster than long-chain fats. They travel directly to the liver, where they are converted into ketones within minutes — ideal before endurance competitions.
🧠 Mental Focus
Ketones are "clean fuel" for the brain. Athletes who take MCT before competitions report better focus and reaction time.
🔥 Thermogenic Effect
MCT has a greater thermogenic effect than other fats — the body uses more energy to metabolize them. May help with weight control.
Usage recommendations:
- Dose: Start with 5 ml (1 tsp), increase to 15-30 ml over 1-2 weeks
- Timing: 30 min before training or in morning coffee ("bulletproof coffee")
- Side effects: Too large a dose may cause diarrhea — always start with small doses!

❓ Most Common Questions About Oils
Why Can't You Fry with Olive Oil?
Yes, but only at low temperature (<180°C). At higher temperatures valuable polyphenols break down, and the oil starts producing acrolein and other toxic compounds. For high-temperature cooking, choose avocado, ghee or rapeseed oil.
Is MCT Oil Suitable for Weight Loss?
MCT may help with weight loss due to a greater thermogenic effect and a feeling of satiety. It is believed that replacing other fats with MCT can lead to losing 1-2 kg more over 12 weeks. However, MCT is calorie-dense (115 kcal/VŠ) — use it instead of, not in addition to, other fats.
What Is Cold-Pressed Oil and Why Is It Better?
Cold-pressed oil is extracted mechanically, without high temperature or chemical solvents. This preserves vitamins (especially E), polyphenols and antioxidants. Refined oil is cheaper and has a higher smoke point, but has lost most of its biologically active substances.
