Fish sauce is a popular condiment used in many Asian cuisines, known for its savory and umami flavor. However, recent studies have raised concerns about the potential health risks associated with long-term consumption of fish sauce.
Specifically, research suggests that regular consumption of this fermented sauce may be linked to an increased risk of certain types of cancer, including gastric and esophageal cancer.
In this article, we will explore the evidence behind these claims and examine whether fish sauce is truly carcinogenic.
So, if you’re a fan of this pungent condiment, read on to learn more about its potential health effects.
Is Fish Sauce Carcinogenic?
Several studies have investigated the relationship between fish sauce consumption and cancer risk. One ecological study conducted in Fujian Province, China, found a significant correlation between monthly consumption of fish sauce and mortality from gastric cancer. The study included 11,000 subjects from 55 townships, and the results showed that long-term intake of fish sauce may be related to high mortality of gastric cancer.
Another study conducted in China examined 1,200 people with esophageal cancer and a matching group without the illness from the same region. The researchers found that esophageal cancer was 16 times more prevalent in those who ate fermented fish sauce daily. The study also suggested that the sauce may increase the risk of developing stomach and thyroid cancer.
While these studies suggest a potential link between fish sauce consumption and cancer risk, it is important to note that they are not conclusive. Further research is needed to confirm these findings and determine the exact mechanisms behind any potential carcinogenic effects.
What Is Fish Sauce?
Fish sauce is a condiment that has been used for thousands of years to add flavor to dishes. It is a pungent, savory liquid that is made by fermenting small fish such as anchovies in salt for anywhere from a couple of months to several years. During the fermentation process, natural bacteria break down the fish, producing a briny, savory liquid that is rich in umami, the earthy, savory flavor field that makes things like mushrooms and soy sauce taste complex and crave-able.
Fish sauce is commonly used in Southeast Asian cooking and provides a driving flavor in dishes like larb, Vietnamese marinated meats, green papaya salad, stir-fries, and pad thai. It can also be used in non-Asian cooking to boost the salty, savory flavor of sautéed greens, pastas, roast chicken, or broths.
There are hundreds of varieties of fish sauce available on the market, but one brand that stands out for its availability and flavor is Red Boat. Made in Vietnam using only anchovies and salt, Red Boat’s fish sauce has a fresh and well-balanced taste thanks to its slower fermentation process.
While fish sauce is an ingredient that can add depth and complexity to dishes, some studies have suggested a potential link between long-term intake of fermented fish sauce and an increased risk of certain cancers such as gastric and esophageal cancer. However, further research is needed to confirm these findings and determine the exact mechanisms behind any potential carcinogenic effects.
The Fermentation Process Of Fish Sauce
Fish sauce is a condiment commonly used in Southeast Asian cuisine. It is made by fermenting small marine fish and table salt in a process that can take up to two years. During fermentation, the fish are completely liquefied, and the resulting liquid is then strained and bottled.
The fermentation process of fish sauce involves the breakdown of proteins in the fish by enzymes produced by bacteria and yeast. This process releases amino acids and other compounds that contribute to the flavor and aroma of the sauce. However, it can also lead to the formation of N-nitroso compounds, which are known to be carcinogenic.
N-nitroso compounds are formed when nitrite or nitrate reacts with amino acids or amines under acidic conditions, such as those found in the stomach. These compounds can damage DNA and increase the risk of cancer.
Fish sauce is particularly rich in precursors of N-nitroso compounds, such as creatinine and other nitrogen-containing compounds. These precursors can be converted into N-nitroso compounds under simulated human stomach conditions, as shown in experiments with Wistar rats.
The Potential Health Risks Of Fish Sauce
Fish sauce is a popular condiment in many Southeast Asian countries, made by fermenting fish with salt for several months. However, some studies have suggested that regular consumption of fish sauce may increase the risk of developing certain types of cancer.
One potential health risk associated with fish sauce consumption is gastric cancer. The aforementioned study conducted in Fujian Province found a significant correlation between monthly consumption of fish sauce and mortality from gastric cancer. This suggests that long-term intake of fish sauce may be related to high mortality of gastric cancer.
Another potential health risk associated with fish sauce consumption is esophageal cancer. A study conducted in China found that esophageal cancer was 16 times more prevalent in those who ate fermented fish sauce daily. The study also suggested that the sauce may increase the risk of developing stomach and thyroid cancer.
While these studies suggest a potential link between fish sauce consumption and cancer risk, it is important to note that they are not conclusive. Further research is needed to confirm these findings and determine the exact mechanisms behind any potential carcinogenic effects. It is also important to note that other factors, such as genetics, lifestyle, and environmental factors, may also contribute to the development of cancer.

While these studies suggest a potential link between fish sauce consumption and cancer risk, it is important to note that they are not conclusive. Further research is needed to confirm these findings and determine the exact mechanisms behind any potential carcinogenic effects. It is also important to note that these studies were conducted in specific regions and populations and may not be applicable to all individuals who consume fish sauce. As with any food or condiment, moderation is key, and individuals should consult with their healthcare provider if they have concerns about their diet and cancer risk.
Other Health Concerns Associated With Fish Sauce Consumption
In addition to the potential link between fish sauce consumption and cancer risk, there are other health concerns associated with its consumption. One major concern is the high sodium content of fish sauce, which can contribute to high blood pressure and an increased risk of heart disease. Some brands of fish sauce also contain additives such as MSG, which can cause adverse reactions in some people.
Furthermore, fish sauce is derived from fermented fish, which can lead to histamine intolerance in some individuals. Histamine intolerance can cause symptoms such as headaches, hives, and gastrointestinal issues.
It is important to note that these health concerns are not unique to fish sauce, and they may also be associated with other fermented foods and high-sodium condiments. As with any food, moderation is key when consuming fish sauce, and individuals with specific health concerns should consult with a healthcare professional before adding it to their diet.
How To Enjoy Fish Sauce Safely And In Moderation
If you enjoy the flavor of fish sauce, there are ways to consume it safely and in moderation. First, it is important to choose a high-quality fish sauce that contains only two ingredients: fish and salt. Avoid brands that contain added preservatives or sugar, as these can be harmful to your health.
It is also important to use fish sauce in moderation. While it can add a delicious umami flavor to your dishes, too much of it can be harmful. The World Health Organization recommends a maximum daily intake of 2.1 micrograms of arsenic per kilogram of body weight. Since some fish sauces have been found to contain high levels of arsenic, it is important to be mindful of how much you are consuming.
To enjoy fish sauce safely, consider using it as a condiment rather than a main ingredient in your dishes. A little bit goes a long way, so start with a small amount and add more as needed. You can also try diluting the fish sauce with water or other liquids to reduce the concentration of arsenic.
Finally, if you have concerns about the safety of fish sauce, consider talking to your healthcare provider. They can provide personalized recommendations based on your individual health status and dietary needs.
