Supermarket shelves are stocked with various oils, from affordable vegetable oil to higher-priced coconut oils which promise health benefits.

Oils and fats have long been at the heart of nutritional discussions, and to grasp why it matters, it helps to look at the various kinds of fatty acids they include.

Not all fats behave the same way in the body—some increase blood cholesterol while other types assist in reducing it.

Cholesterol is a naturally occurring fatty substance made in the body's liver and can also be found in certain foods we consume. An excess of LDL cholesterol can lead to a build-up of plaque inside the walls of blood vessels, causing them to become constricted or obstructed.

Given the numerous shifting messages, knowing which product to pick can frequently feel overwhelming.

According to a Professor of Population Health and Nutrition, no one oil holds the magic key to wellness, and she clarifies three widespread misconceptions about kitchen oils.

1. Use Sunflower Oil for Everyday Cooking

Vegetable oil and sunflower-based oils sometimes receive negative attention, with certain sources suggesting they are highly processed and can lead to inflammation that may damage heart health.

However, there lacks evidence to support these claims.

In fact, these oils have a low amount—five to ten percent—of less healthy saturated fats and are rich in more beneficial unsaturated fats. Polyunsaturated fats, including essential fatty acids, are vital for cognitive and cardiovascular health.

The expert states that these oils are "definitely good for us."

She explains that they can offer a decrease in disease risk "when high-saturated fats such as butter are substituted with these oils."

At around two pounds per liter in most supermarkets, it's also a highly economical option for cooking at home.

Second: Spreadable Fats Can Help Reduce LDL Cholesterol

Margarine has had a bad reputation for decades, and many of us believe we should avoid it.

This is due to it once contained damaging trans fatty acids that are strongly linked with heart disease, but modern day margarines "contain nearly no harmful trans fats," according to the expert. "So it can actually be included in a balanced diet and lower the bad cholesterols."

Dairy butter also isn't off the menu entirely. "If you love butter, for instance on your bread, certainly use it," advises the expert.

You can use either margarine and butter for culinary purposes, but she recommends sometimes swapping them out for cooking oil instead, which has less saturated fatty content.

National health advice recommend maintaining your saturated fat consumption below ten percent of daily calories, and this is simpler to do if you're opting for oil to cook with instead of butter.

Third: Extra Virgin Olive Oil Isn't Ideal for Deep Frying

Oils behave differently when exposed to heat, making some of them unsuitable for high-heat cooking.

Extra virgin olive oil, as an instance, is packed with antioxidants and nutritious elements, but its low smoke point means it is more suited for drizzling over salads or finishing dishes rather than deep frying.

The smoke point is the degree at which the fats in the oil begin to degrade and emit harmful substances that can make the oil become burnt or unpleasant.

According to a restaurateur, for pan-frying he uses a basic olive oil.

But for frying foods something like french fries or fried fish, vegetable or sunflower oil is best as they tolerate elevated heat without decomposing.

Research have also shown that oils heated to beyond their smoking point release toxic unwanted compounds.

But the professor says that this kind of cooking in the household is not very common and that long-term health studies still show that vegetable oils "consistently are linked with better outcomes for long-term health conditions."

Which Oils Can One Be Choosing?

If you're looking for a straightforward cooking approach:

• For everyday cooking: Sunflower oil are cost-effective, healthy, and versatile. You could also use a basic olive-based oil
• For salads and finishing dishes: High-quality olive oil imparts taste and nutritional value
• For high-temperature frying: Opt for a heat-resistant oil like vegetable oil
• To add diverse tastes: While they may not have the same nutritional advantages as olive oil, you could use sesame oils for cold dishes if you like the flavour

Overall, the professor emphasizes it is more beneficial to consider your overall eating habits instead of obsess over which container to purchase.

"I would recommend going with what flavor and cost considerations you have and trying out with different types of oil that will bring you some wellness advantages," she adds.
