Which oil was banned by the FDA in 2018 due to its health risks?

The oil that was banned by the FDA in 2018 due to its health risks is trans fats. Trans fats, also known as partially hydrogenated oils, were commonly used in processed foods to improve texture and extend shelf life. However, research has shown that trans fats significantly increase the risk of heart disease by raising LDL (bad) cholesterol levels while lowering HDL (good) cholesterol levels.

The ban was a crucial public health measure aimed at reducing the prevalence of cardiovascular diseases associated with trans fat consumption. Many food manufacturers had already begun to reduce or eliminate trans fats from their products prior to the ban in anticipation of regulatory changes, which reflected growing concern about their impact on health.

On the other hand, the oils mentioned in the other options—olive oil, coconut oil, and canola oil—do not carry the same level of health risks associated with trans fats. In fact, olive oil is often promoted for its heart-healthy monounsaturated fats, and canola oil is considered a healthier option as well. While coconut oil has been a topic of debate regarding its saturated fat content, it was not subject to a ban due to health risks like trans fats were.
