Scientists have found that the nutrients from cabbage, especially carotenoids, are difficult for the body to absorb if the cabbage is consumed without the addition of oil. Cooking cabbage does not improve the absorption of these nutrients. However, the addition of oil dressings or nanoemulsion sauces significantly increases the availability of carotenoids for the body. Nanoemulsions are special emulsions with very small oil droplets that improve the absorption of nutrients. This research suggests that combining kale with fats may increase its health benefits. The results may lead to the development of new, more effective vegetable dressings. Such dressings could help make better use of nutrients in the daily diet.
