What is the source of oils used in nutrition?

In the context of nutritional oils, the primary source is derived from plants. Plant oils, such as olive oil, canola oil, and sunflower oil, are extracted from various seeds, nuts, and fruits. These oils provide essential fatty acids and are rich in vitamins, contributing beneficially to human health.

Although marine animals do produce certain oils, like fish oil, which is rich in omega-3 fatty acids, they are not the main source of oils in nutrition. The vast majority of culinary and nutritional oils are from plant sources, making them the prevalent choice. Additionally, while there are synthetic sources of oils used in various applications, they are typically not considered natural or nutritious in the same way that oils derived from plants are. Hence, the correct understanding of nutrition sources clearly positions plants as the primary origin of oils in human diets.
