What Is Soy?
Here you will find out is soy sauce vegan and what is it made of. Soy foods are made from soybeans, a species of the legume family, which originated in Southeast Asia (13). Soy protein is a favored meat replacement, thus being a great option for vegetarians. Indeed, soy is one of the few complete plant-based protein sources that contains the nine essential amino acids (11) which are vital for the synthesis of body protein (8). In fact, soy is more suitable than some animal products which are rich in protein but concurrently high in saturated fat (13). Soy is extremely nutritious, containing a number of vitamins and minerals. Among these are B complex vitamins, magnesium, potassium, and fiber, which are an integral part of a healthy and balanced diet. In addition, soy foods are classified into two groups, fermented and unfermented ones. Soy can be fermented with mold, yeast, and beneficial bacteria, with the result being that the protein and sugars in soy are decomposed. This is beneficial as fermented soy is processed and absorbed better than unfermented (18).
The List Of The Most Famous Soy Foods
Soy can be eaten in different forms and cooked in a variety of ways. Common soy-containing foods include:
- Soy milk. This one is produced by soaking, grinding, and straining soybeans. Soy milk contains a great amount of protein and B complex vitamins, vital for the human musculoskeletal system, nerves, and wellbeing in general. What soy milk lacks, though, is calcium, which is found in cow’s milk. Manufacturers though often put the product through a fortification process to artificially enrich it with vitamins that are not naturally present in the beverage (1).
- Miso. This soy food is a traditional Japanese condiment, which is versatile enough to be an excellent additive to virtually any dish. Miso is not very rich in protein but what it has in abundance is sodium. Reduced blood pressure and the prevention of cardiovascular diseases and stroke are positive results from this (1, 19).
- Tofu. Tofu cheese, or soybean curd, is the product of hot soy milk coagulation. It’s consistency is soft, has a mild flavor, contains protein and B complex vitamins in great amounts. Tofu is low in sodium (1).
- Soy sauce. Another popular soy food that has spread far beyond Asia. Soy sauce is the result of the fermentation process of soybeans. This sauce can not be deemed a soy product rich in protein. In addition, it contains a high amount of salt, which is why it might not be the healthiest food option (1).
- Whole soybeans. This is what comes naturally from the plant and comes in yellow, brown, and black colors. These might be the most nutritious soy food, since they are very high in protein and dietary fiber (1).

Too much of anything isn’t a good idea, which is why your soy intake should be moderate (12). Secondly, soy functions as a cancer prevention device primarily among teenage girls and young women (10). Multiple studies have shown that soy enhances estrogen and progesterone receptor expression in benign mammary tissue of young women (6).
- A decrease by 4-5mm Hg and 2-3mm Hg in systolic (SBP) and diastolic blood pressure (DBP) respectively has been observed in normotensive soy consumers. The reduction is estimated to be even higher in hypertensive people, reaching 9 mmHg in SBP and 5 mmHg in DBP (3).

What Is Soy Sauce?
Soy sauce is a mainstay in Asian food and is being produced and sold in various parts of the world. Over its eight century history, a plethora of soy sauce recipes have appeared. For example, of the Chinese soy sauces, is a light soy sauce that, unlike the dark one, is a result of the initial extraction. The dark soy sauce, on the other hand, must be matured longer and contain caramel. This makes the dark version of the condiment sweeter than the light one. There is also the regular type of the sauce, which combines both the light and dark ones (15).
Japanese soy sauces are also divided into light and dark. The light one goes under the name Usukuchi. The paramount difference between Usukuchi and the Chinese light soy sauce lies in the salt content. The same goes for Tamari, which is not that as spicy as the Chinese dark soy sauce. There is also Shoyu, which takes 2 years to fully mature (15).
Both the Chinese and the Japanese variants of soy sauce are much more than food; these represent their respective cultures. Hence, it is highly recommended to use Chinese sauces for Chinese traditional dishes and Japanese ones for Japanese meals.

Too much histamine can induce dizziness, headaches, and digestive problems. Another topic to consider about soy sauce is that it can cause allergies. If you are intolerant to wheat, gluten, or soybeans themselves, you should exclude soy sauce from your diet (7, 9).
