Overheating oils past their smoke point can destroy beneficial nutrients and create harmful compounds. This crucial point raises the question: does a higher smoke point mean a healthier oil, or are other factors more important for your well-being?

Omega-3 fatty acids, like those found in krill oil, are highly susceptible to damage from heat, light, and oxygen. This sensitivity directly impacts the oil's potency and freshness, prompting many to question, "should I refrigerate my krill oil?" The answer lies in understanding how these elements affect the delicate compounds within the supplement.

A 2018 study published in *Acta Scientific Nutritional Health* found that extra virgin olive oil was the most chemically stable oil when heated, even compared to those with higher smoke points. This research directly addresses the common misconception, answering the question: does olive oil release toxins when heated? The evidence suggests that, under normal cooking conditions, it is a stable and safe choice.

A high iodine value indicates a high degree of unsaturation in a fat or oil, making the substance more reactive. This analytical parameter, known as the iodine value indicator, is crucial for determining the quality and stability of various lipid-based products, from paints to food.

A 2018 study found that extra virgin olive oil was one of the most stable oils when heated, producing the fewest harmful compounds, challenging the widely held belief that you should not use olive oil for cooking. This evidence suggests that olive oil is a perfectly safe and healthy choice for most kitchen applications.

A modern Western diet has drastically shifted the omega-6 to omega-3 fatty acid ratio from an ancestral 1:1 balance to as high as 15:1 or 20:1, a change largely driven by the pervasive use of refined vegetable oils. This fatty acid imbalance is at the core of many health concerns linked to cooking oils.

Oxidation rates for unsaturated fatty acids have been reported to be as much as 100 times faster than saturated types, highlighting a critical stability difference. This brings into focus the fundamental question: are saturated fatty acids more stable than unsaturated, and what causes this significant difference?

According to a recent Australian study, extra virgin olive oil demonstrates greater oxidative stability than coconut oil during heating, challenging common beliefs about smoke points. This raises the question: is coconut oil healthier than olive oil for frying? The answer depends on a deeper look at their nutritional profiles and how they react to high temperatures.

According to the American Heart Association, choosing vegetable oils with less than 4 grams of saturated fat per tablespoon is a key step towards heart health. Answering what is the healthiest for deep frying involves selecting oils that remain stable under high temperatures to prevent the release of harmful compounds.

Studies have shown that extra virgin olive oil possesses high oxidative stability, meaning it resists breaking down under heat better than many other common oils. This critical fact addresses the popular question: is olive oil healthier when cooking, and does heat compromise its benefits?
