                                Over a century of research has established that while the human body can produce many types of fats, it is fundamentally incapable of synthesizing a specific class of polyunsaturated fats known as essential fatty acids (EFAs). These vital nutrients, including alpha-linolenic acid (ALA) and linoleic acid (LA), must be obtained directly from the diet.
