Black sesame is the black seed of sesame in the sesame family, containing a large amount of fat and protein, as well as nutrients such as sugars, vitamin A, vitamin E, phospholipids, calcium, iron, chromium, etc. It can be made into various delicious foods. Generally, it is edible per capita.

The efficacy and function of black sesame

　　Black sesame can be used as both medicine and food, with the effects of nourishing the liver and kidneys, nourishing the five organs, nourishing essence and blood, and moistening the intestines and dryness. It is considered a nourishing holy product. Black sesame has health benefits, partly because it contains high-quality protein and abundant minerals, and partly because it is rich in unsaturated fatty acids, vitamin E, precious sesamin and melanin.

1. Calcium supplementation

　　There are many calcium supplements on the market, although advertisements claim to have a high absorption rate, the actual effect may vary greatly. From a scientific perspective, dietary supplements are still the best way to supplement calcium. It is easy for people to think of milk and eggs to improve food calcium supplementation, but little do they know that the calcium content of black sesame is much higher than the first two. The calcium content in every hundred grams of black sesame is close to 800 milligrams, while the calcium content in every hundred grams of milk is only about 200 milligrams. Therefore, it can be seen that black sesame is a good calcium supplement.

2. Lowering blood pressure

　　The causes of hypertension are multifaceted, and one important one is a high salt diet. Nutrition experts recommend that each person consume no more than 6 grams of salt per day, but in reality, most people cannot do so. Therefore, recommending a high potassium diet is very important because one of the main functions of potassium intake in the human body is to promote the excretion of sodium. Black sesame is rich in potassium, with a higher potassium content per hundred grams and much lower sodium content. The ratio of potassium to sodium content is close to 40:1, which is very important for controlling blood pressure and maintaining heart health.

3. Wufa Runfa

　　Modern research has shown that the decrease in melanin secretion by melanocytes in hair follicles is the main cause of white hair, and the decrease in tyrosinase activity is one of the pathological mechanisms. Research has found that black sesame water extract can promote tyrosinase expression, thereby increasing the synthesis of melanin and allowing white hair to turn black again.

4. Nourishing and Moisturizing Skin

　　Currently, research suggests that reducing the production of free radicals, clearing aging metabolites, and improving antioxidant enzyme activity are effective methods for delaying skin aging. Black sesame is rich in natural vitamin E, which ranks first among plant-based foods. Vitamin E is a good antioxidant, and appropriate supplementation of vitamin E can have a moisturizing and beauty enhancing effect. In addition, sesame is one of the four major oil crops, and the oil content of black sesame is mostly unsaturated fatty acids, with linoleic acid accounting for about half each. Linoleic acid is an ideal skin beauty agent because when the human body lacks it, it can also easily cause symptoms such as dry skin, thickened scales, slow growth, and cholesterol deposition in blood vessels. Therefore, linoleic acid is also known as "beauty muscle acid".
