They know that some cooking oils – like olive oil and avocado oil, which a nutritionist recently told us they love – are healthier to cook than others, especially given the effects some have been shown to have on heart health. A new study just came to a conclusion about a common but often misunderstood cooking oil. They say this one oil has puzzled scientists and consumers for ages, but it actually promotes cardiovascular health and lowers cholesterol.
A group of nutritional researchers from Pennsylvania State University and Texas Tech University led a study that was just published in the journal Nutrition. The research team found that while soybean oil is the most widely consumed oil in both the US and worldwide, its dangers versus its benefits is a debate that has puzzled consumers and health professionals for years. They stated, “Despite the ubiquity of soybean oil in the US food supply and its established cardioprotective effects, US consumers rate soybean oil in comparison to many other oils such as olive oil, canola oil, coconut oil and avocado oil.”

That’s problematic, they say. This is because saturated fat is widely believed to be a major cause of heart disease and death. However, a 2010 study found that in 80% of countries, double the number of cases of coronary artery disease were caused by insufficient omega-6 polyunsaturated fatty acids (e.g. from soybean oil) compared to coronary artery disease caused by a high Saturated fat content.
To shed light on what they view as these common misconceptions, the researchers conducted an analysis of previous studies all of which looked at the effects of soybean oil on health, including aspects of cardiovascular disease prevention, blood fat (cholesterol ), inflammation and oxidation stress. Their results show that soybean oil, as a polyunsaturated fat, not only “does not affect inflammatory biomarkers and does not increase oxidative stress”, but that the blood cholesterol level is lowered when soybean oil replaces saturated fat.
The researchers conclude:
[…C]Overall, the evidence suggests that soybean oil has beneficial effects on [cardiovascular disease] Risk. Additionally, dietary recommendations support consumption of soybean oil as part of a healthy diet for overall health and health [cardiovascular disease] Prevention and management.
It’s pretty scientific, but it seems that soybean oil definitely has some benefits. Information like this could help you make good choices the next time you’re in the oil run. Check out one important effect drinking coffee has on your liver and read on:
