Which substance is produced by the body and is found in animal fats and some plant foods?

The substance produced by the body that is found in animal fats and some plant foods is cholesterol. Cholesterol is a type of lipid that plays several essential roles in the body, including forming cell membranes, producing hormones, and assisting in the digestion of fats. While it is primarily made by the liver, it can also be obtained from dietary sources, particularly animal products such as meat, dairy, and eggs. Some plant foods, like avocados and certain oils, contain phytosterols, which are similar to cholesterol but are a different type of compound.

Understanding the role of cholesterol emphasizes its importance as a necessary substance despite often being discussed in the context of heart health and dietary restrictions. This underscores the need for a balanced approach to diet, taking into account both the benefits of cholesterol and the potential risks associated with excessive intake.
