1. Calcium supplement: There are many calcium supplement products on the market. Although the advertisement says that they have a high absorption rate, the actual effect may be far from it. From a scientific point of view, it is better to supplement calcium with food. It is easy to think of milk and eggs to improve food calcium supplement, but people don't know that the calcium content of black sesame seeds is much higher than the first two. The calcium content in black sesame seeds per100g is close to 800 mg, while the calcium content in milk per100g is only about 200 mg. Therefore, black sesame is the best calcium supplement food.

2. Lowering blood pressure: There are many reasons for high blood pressure, one of which is a high-salt diet. Nutrition experts suggest that each person should eat no more than 6 grams of salt every day, but in real life, most people can't. Therefore, it is very important to recommend a high potassium diet, because one of the main functions of potassium intake is to promote sodium excretion. Black sesame is rich in potassium, with a high potassium content per 100 grams of black sesame, but much less sodium. The ratio of potassium to sodium is close to 40: 1, which is very important for controlling blood pressure and maintaining heart health.

3. Hair blackening and moistening: Modern research has proved that the decrease of melanin secretion by hair follicle melanocytes is the main cause of gray hair, and the decrease of tyrosinase quantity is one of the pathological mechanisms. It was found that the water extract of black sesame can promote the expression of tyrosinase, improve the synthesis of melanin, and make white hair turn black again.

4. Nourishing skin and moistening skin: It is considered that reducing the production of free radicals, eliminating aging metabolites and improving the activity of antioxidant enzymes are effective methods to delay skin aging. Black sesame is rich in natural vitamin E, ranking first among plant foods. Vitamin E is a good antioxidant, and proper vitamin E supplementation can play a role in moisturizing and beautifying.

In addition, sesame is one of the four major oil crops. The oil content of black sesame is mostly unsaturated fatty acid, and linoleic acid accounts for about half. Linoleic acid is an ideal skin care agent, because when people lack linoleic acid, it is easy to cause symptoms such as dry skin, enlarged scales, growth retardation, cholesterol deposition in blood vessels and so on. Therefore, linoleic acid is also called "creatine"

Second, black sesame taboo:

People with chronic enteritis and diarrhea in loose stool should not eat it.

Selection method of black sesame

1. Normal black sesame seeds will fade slightly after soaking in water, but the color will not be too dark. There is a process for the natural pigment in black sesame to dissolve in water, so raw black sesame will not fade quickly in cold water at room temperature, except for aged black sesame.

2. Put raw black sesame seeds in cold water. If the color fades quickly, it is probably dyed. In addition, because only the seed coat of black sesame is black and the endosperm is white, you can cut black sesame with a knife to see if it is white inside. You can also put black sesame seeds in your palm. If the palm turns black soon, it means that the black sesame seeds are probably dyed.
