Common sesame seeds generally include black sesame and white sesame. Black sesame paste is rich in flavor and mellow in taste, and it is a food that many people like to eat since childhood. White sesame seeds are generally placed on sesame cakes, fried foods, etc., which can enhance the fragrance. Now, white sesame seeds can also be added to many hot pot ingredients.
But do you know which one has higher nutritional value, black sesame or white sesame?
The oil content of black sesame and white sesame is about 50%, and the main components are oleic acid, linoleic acid, palmitic acid and glyceride. Including protein about 20%; It also contains sesamin, sesamol, lecithin, sucrose, pentosan, calcium, phosphorus, iron and other substances, vitamin A, vitamin D, vitamin E and so on. And the nutrients are basically the same.
Sesame contains sesamin, which has the effects of scavenging free radicals and antioxidation, and is helpful to lower cholesterol, resist bacteria and activate immune function.
Sesame is rich in linoleic acid, which can keep skin soft and moist. Vitamin E can enhance the vitality of tissues and cells, and has a "moisturizing" effect on collagen fibers and elastic fibers in the skin.
Studies in France have found that sesamol in sesame can inhibit the synthesis of melanin by inhibiting tyrosinase in cells, thus giving sesame a certain whitening effect.
But if there is any difference between black sesame and white sesame, everyone must be familiar with the saying that black sesame cares for black hair, and it is generally believed that it can be supplemented by shaping.
In fact, you can see that most of the black in sesame is anthocyanin, and the black substance in our hair is an amino acid derivative synthesized by melanocytes. They are not the same kind of substances, so they cannot be supplemented.
Even similar substances, such as this kind of macromolecules, will become tiny nutritional units after being digested by the digestive tract, and may follow the blood to wherever it is needed, instead of "supplying" it to where you want it to go.
Therefore, black sesame has no effect of blackening hair, and most of them have no scientific basis.
However, although eating black sesame seeds can't make black hair, it is precisely because anthocyanins in black sesame seeds are richer than those in white sesame seeds that anthocyanins give black sesame seeds stronger antioxidant and free radical scavenging ability.
But don't expect a little difference between sesame seeds, because the amount we eat is far from the amount of these ingredients. Therefore, black sesame and white sesame are very good foods, and maintaining the diversity of food types helps us to stay healthy.
