What does oil do in cooking?

Oil allows higher cooking temperatures than water, making cooking faster and more flavorful, while likewise distributing heat, reducing burning and uneven cooking. It sometimes imparts its own flavor. Cooking oil is also used in food preparation and flavoring not involving heat, such as salad dressings and bread dips.

What is the point of oil in cooking?

What happens if you don't use oil when cooking?

You can cook without oil, but the effect is different. You do not use oil just so the food will not stick to the pan, rather you use it to 'fry' the ingredients in question.

Which Cooking Oils are Safe? (Which to AVOID)

What is the unhealthiest oil to cook with?

The worst cooking oils for health are generally considered to be highly refined seed oils like soybean, corn, cottonseed, and canola, due to their high omega-6 content (linked to inflammation) and processing methods (often GMO, sprayed with pesticides). Also problematic are partially hydrogenated oils (trans fats), palm oil, and palm kernel oil for their saturated fat content and impact on cholesterol. Health experts recommend limiting these and opting for olive oil, avocado oil, or butter/ghee for better heart health.
 

Why is oil unhealthy when heated?

It's important to avoid the smoke point (the temperature a fat or oil begins to smoke), as this can produce toxic compounds and bitter or 'off' flavors. Exceeding the smoke point can also destroy valuable nutrients. When selecting your oil, it is important to note that food cooked on the stove top rarely exceeds 350°F.

What's the healthiest oil to cook with?

The healthiest cooking oils are generally extra virgin olive oil (EVOO) for low-to-medium heat (dressings, sautéing) and avocado oil for high-heat cooking (roasting, frying) due to their high monounsaturated fats and antioxidants, while canola, sesame, and unrefined avocado oil are also great choices. The best choice depends on your cooking method, but focus on oils with less saturated fat and avoid partially hydrogenated oils, using all oils in moderation as they are calorie-dense.

Why can't we fry things in water?

Water boils at 100 degrees Celsius (212 degrees Fahrenheit), which is not hot enough for frying. Oil, on the other hand, can reach much higher temperatures without boiling, making it suitable for frying. Additionally, water is a polar molecule while oil is nonpolar, which means they don't mix.

Why shouldn't you fry with olive oil?

Oils behave differently when heated which makes some of them unsuitable for frying. Extra virgin olive oil, for example, is packed with antioxidants and beneficial compounds but its low smoke point means it is better for salad dressings or drizzling over food rather than deep frying.

Why are people swinging olive oil before bed?

People are drinking or "swinging" a small amount of extra virgin olive oil (EVOO) before bed for potential benefits like improved digestion, reduced inflammation, better sleep, and increased fullness, leveraging its healthy fats and antioxidants to support the body's nightly repair processes and promote overall well-being, often as a natural supplement to a Mediterranean-style diet.
 

Why are people avoiding vegetable oil?

People avoid vegetable oils due to concerns that their high omega-6 content, heavy processing, and susceptibility to oxidation when heated promote chronic inflammation, potentially leading to issues like obesity, heart disease, and type-2 diabetes, though some research suggests benefits when used in moderation with a balanced diet. Critics point to inflammation from imbalanced omega-6s, damaging refining chemicals, and harmful byproducts from high-heat frying, while others argue these oils are fine for everyday use, with the real problem being ultra-processed foods containing them. 

Which oil to stay away from?

You should generally avoid highly processed seed oils like soybean, corn, canola, sunflower, safflower, grapeseed, and cottonseed oils, as they are high in inflammatory omega-6s and often extracted with harsh chemicals, leading to potential health issues like inflammation and heart disease. Also limit or avoid palm oil (due to saturated fat) and partially hydrogenated oils (trans fats), opting instead for healthier fats like olive, avocado, or coconut oil for better health. 

What oil do cardiologists recommend?

Cardiologists recommend oils rich in monounsaturated and polyunsaturated fats (MUFAs & PUFAs) over saturated fats, with Extra Virgin Olive Oil often called the gold standard due to strong evidence for reducing heart disease risk, followed by canola, avocado, sunflower, peanut, and safflower oils, all helping to improve cholesterol when replacing less healthy fats like butter or lard. Key is choosing liquid vegetable oils low in saturated fat (under 4g/tbsp) and avoiding trans fats.
