According to a study published on PubMed, repeatedly fried oils, including mustard oil, have been shown to induce detrimental effects on the renal tissues of rats, suggesting potential harm from improper use. This raises important questions about the overall safety of mustard oil for human kidney health when used in cooking.

According to a 2024 study, repeatedly heating cooking oils can increase oxidative stress and contribute to health issues. This raises a critical question for home cooks and professionals alike: does heating up oil make it unhealthy? The answer is nuanced and depends on the oil's type, the cooking temperature, and duration.

According to several studies, the long-term consumption of repeatedly heated oil has been linked to an increased risk of chronic health conditions, including heart disease and certain cancers. While cooking oil is a staple in most kitchens, knowing if oil heating is bad for your health and which oils are best for different temperatures is crucial for minimizing risks and maximizing nutritional benefits.

According to a study conducted on rats, a short-term intake of even low doses of fried oil can significantly increase body weight and cause systemic low-grade inflammation. The process of heating oil to high temperatures dramatically alters its chemical composition, transforming it from a benign cooking medium into a source of harmful toxins, which is why frying oil is unhealthy.
