When turmeric is cooked in oil, the heat helps to dissolve and release curcuminoids, the active compounds in turmeric, making them more bioavailable. This step is important because it enhances the body's ability to absorb and utilize the health benefits of turmeric.
Turmeric contains curcuminoids, primarily curcumin, which are responsible for its vibrant color and many of its health benefits. However, curcumin is not easily absorbed by the body on its own. It's fat-soluble, meaning it dissolves best in fats rather than water.
When turmeric is heated in oil, the oil acts as a solvent, helping to break down the turmeric cells and release the curcuminoids. The heat further aids in this process, increasing the solubility of curcumin in the oil. This creates a solution where the curcuminoids are readily available to be absorbed by the body during digestion.
Furthermore, cooking turmeric in oil can also help to bypass some of the metabolic processes in the liver that would otherwise break down curcumin before it can be utilized. The presence of fats can slow down the metabolism of curcumin, allowing more of it to enter the bloodstream.
Always add black pepper when cooking turmeric in oil. Piperine, a compound found in black pepper, significantly enhances curcumin absorption by inhibiting its breakdown in the liver and intestines. A pinch of black pepper can increase curcumin bioavailability by up to 2,000%.
