Nutritional absorption of kale can be improved with oil

Nutritional experts suggest that adding a small amount of oil to kale can significantly improve the body's ability to absorb its beneficial nutrients. Kale is a nutrient-dense leafy green rich in vitamins K, A, and C, as well as minerals like calcium, magnesium, potassium, and iron.

Because the carotenoids found in kale are fat-soluble, consuming the vegetable with a small amount of fat, such as oil in a dressing, facilitates better absorption. Laboratory models simulating the human digestive system have demonstrated that the presence of fat aids in the uptake of these essential compounds.
