Hello there,

Here's an answer to your query with some internet research and my knowledge,

The digestion of fat begins in the stomach in the human body. Majority of digestion of fat happens once it reaches the small intestine. Most of the nutrients are absorbed in the small intestine.

The p ancreas produces enzymes that break down fats, carbohydrates, and proteins. Liver produces bile that helps in digestion of fats and certain vitamins.

Thank you.
