Skin melanin deposition is closely related to ultraviolet radiation, endocrine and living habits, and has nothing to do with eating soy sauce.

I. Introduction

Soy sauce will not cause pigment precipitation. Medical research has found that human skin color is related to the melanin content in the human body, and has nothing to do with the color of food in the diet.

The amount of melanin is mainly regulated by endocrine, and it will also increase due to ultraviolet radiation in the sun. For example, if the sun shines for a long time in summer, the skin color becomes darker, and the sun shines for a short time in winter, the skin color will become lighter, so there is a phenomenon that the skin is black in summer and white in winter.

Soy sauce is a condiment made by fermenting wheat, soybeans and other raw materials. Although it is brown, it will be digested into simple substances and then absorbed after entering the human gastrointestinal tract. The pigment in soy sauce will not directly transfer to the skin, so it has no effect on the synthesis of melanocytes. Therefore, eating soy sauce will not affect skin color.

Second, the efficacy

When cooking food, adding a certain amount of soy sauce can increase the flavor of food and make its color look better, thus increasing appetite.

The main raw material of soy sauce is soybean, and soybean and its products are rich in minerals such as selenium and have anti-cancer effects.

Soy sauce contains a variety of vitamins and minerals, which can reduce human cholesterol, reduce the incidence of cardiovascular diseases, and reduce the damage of free radicals to human body.

Anti-cancer soy sauce is a liquid condiment with special color, fragrance and taste, which is made from soybean, wheat or bran by microbial fermentation and other procedures.
