Nutritionists have proposed that the nutritional value of various natural foods grown in nature is closely related to their color, with their nutritional value ranked in the following order: black foods are the best, followed by red → yellow → white.

Black sesame
—A nourishing delicacy. Black sesame is rich in iron, which can improve anemia, and it is also rich in vitamin E, which can slow down cell aging. Regular and moderate consumption of black sesame can nourish the skin, darken hair, benefit the brain, nourish the liver and kidneys, lower blood lipids, and prolong life, resisting aging.
