Discussion: The three primary reasons why we need to eat natural oils and fats regularly.

To lose weight, it is necessary to eat natural fats and oils.
Vitamins E, D, A, and K are soluble in fat and natural oils and are essential for proper metabolism and the immune system. Avoiding eating natural oils and fats is a mistake.

Vitamin D and omega-3 fatty acids are essential for the immune system to prevent inflammatory processes.
Absorption and regeneration of the gut wall tissue require emulsified foods containing natural oils and fats.

Bile (produced in the liver) is a greasy, alkaline base fluid containing cholesterol. Its function is, among other things, to neutralize the acidity of the stomach.
Fat is an energy reserve for distress and an integral part of many tissues (such as brain tissue, all cell membranes, and hormones). So, instead of synthesizing it, it's better to prepare it.
