Cilantro, also known as coriander, is a popular herb used in various cuisines around the world. However, it has a unique property that sets it apart from other herbs: it is extremely polarizing. While some people enjoy the fresh, citrusy flavor of cilantro, others find it repulsive and describe its taste as soapy or metallic. But why is cilantro so gross to some people? In this article, we will delve into the science behind the hatred for cilantro and explore the possible reasons behind its polarizing effect.
Introduction to Cilantro
Cilantro is a fast-growing, annual herb that is native to the Middle East and the Indian subcontinent. It is a member of the parsley family and is also known as coriander, although the terms are often used to refer to different parts of the plant. The leaves of the plant are commonly used as a herb, while the seeds are used as a spice. Cilantro has been used in cooking for thousands of years and is a key ingredient in many dishes, including Mexican, Indian, and Asian cuisine.
The Complexity of Taste
Taste is a complex sense that is influenced by a combination of genetic and environmental factors. The sense of taste is mediated by taste receptors on the tongue, which detect chemicals in food and send signals to the brain. The brain then interprets these signals as specific tastes, such as sweet, sour, salty, or bitter. However, the perception of taste can vary greatly from person to person, and genetic differences in taste receptors can affect the way people perceive certain flavors.
The Science Behind Cilantro Hate
Research has shown that the hatred for cilantro is not just a matter of personal preference, but is actually linked to a specific genetic trait. A study published in the journal Flavour found that a significant proportion of people who dislike cilantro have a specific variation in the OR6A2 gene, which codes for an olfactory receptor. This receptor is responsible for detecting certain aldehyde chemicals, which are found in cilantro. People with this genetic variation are more sensitive to these chemicals and may perceive them as unpleasant or soapy.
The Role of Genetics in Taste Perception
Genetics play a significant role in determining our taste preferences. Research has identified several genes that are associated with taste perception, including the TAS2R38 gene, which codes for a bitter taste receptor. People who have a certain variation in this gene are more sensitive to bitter tastes and may be more likely to dislike certain foods. Similarly, the OR6A2 gene, which is associated with cilantro hate, is just one example of how genetic differences can affect our perception of certain flavors.
Cultural and Environmental Factors
While genetics play a significant role in determining our taste preferences, cultural and environmental factors also have an impact. People who are exposed to a wide variety of foods and flavors from a young age may be more likely to develop a taste for certain herbs and spices, including cilantro. On the other hand, people who are not exposed to these flavors may find them unpleasant or unfamiliar. Additionally, cultural and social factors can influence our perception of certain foods and flavors, with some cultures or social groups embracing certain flavors while others reject them.
Brain Structure and Function
Brain structure and function also play a role in determining our taste preferences. Research has shown that the brain’s reward system is activated when we eat foods that we enjoy, releasing dopamine and other neurotransmitters that reinforce the behavior. People who enjoy cilantro may have a more active reward system when they eat the herb, while people who dislike it may have a less active reward system. Additionally, the brain’s limbic system, which is responsible for emotion and memory, can also influence our perception of certain flavors, with some people associating cilantro with negative emotions or memories.
Other Possible Explanations for Cilantro Hate
While the genetic explanation for cilantro hate is the most widely accepted, there are other possible explanations for why some people may dislike the herb. Some people may be sensitive to the sulfur compounds found in cilantro, which can give it a strong or unpleasant flavor. Others may be put off by the texture or appearance of the herb, which can be quite different from other herbs and spices. Additionally, people who have had negative experiences with cilantro in the past, such as eating it in a dish that was too spicy or overpowering, may develop a lasting dislike for the herb.
Food Memories and Emotions
Food memories and emotions can also play a significant role in shaping our taste preferences. People who have positive memories associated with cilantro, such as eating it in a favorite dish or with loved ones, may be more likely to enjoy the herb. On the other hand, people who have negative memories or emotions associated with cilantro may be more likely to dislike it. This is because the brain’s limbic system is closely linked to the sense of taste, and emotions can greatly influence our perception of certain flavors.
Cross-Cultural Comparisons
A comparison of different cultures and their attitudes towards cilantro can provide further insight into the mystery of why some people dislike the herb. In some cultures, such as Mexican and Indian cuisine, cilantro is a staple herb and is used in many dishes. In these cultures, people are often exposed to cilantro from a young age and develop a taste for it. In other cultures, such as some European countries, cilantro is not as commonly used and may be viewed as an exotic or unusual ingredient. People from these cultures may be more likely to dislike cilantro due to its unfamiliarity or perceived strangeness.
Conclusion
In conclusion, the hatred for cilantro is a complex phenomenon that is influenced by a combination of genetic, cultural, and environmental factors. While the genetic explanation for cilantro hate is the most widely accepted, other factors such as cultural and environmental influences, brain structure and function, and food memories and emotions also play a role. Ultimately, the perception of cilantro as gross or unpleasant is a highly subjective and personal experience that can vary greatly from person to person. By understanding the factors that contribute to this perception, we can gain a deeper appreciation for the complexity of human taste and the many factors that influence our culinary preferences.
In the following table, we summarize the key points discussed in this article:

By considering these factors, we can gain a deeper understanding of the complex and multifaceted nature of human taste and the many factors that influence our culinary preferences. Whether you love or hate cilantro, there is no denying the significant impact it has on our culinary experiences and the strong emotions it evokes in people around the world.
What is the main reason why some people find cilantro unpalatable?
The main reason why some people find cilantro unpalatable is due to a genetic variation in their olfactory receptors. Research has shown that a significant percentage of people who dislike cilantro have a specific genetic trait that makes them more sensitive to certain aldehyde chemicals, which are found in cilantro. These chemicals are responsible for the herb’s distinctive flavor and aroma, but for people with this genetic variation, they can be overwhelming and unpleasant. This genetic variation is more common in people of European ancestry, which may explain why cilantro is often more polarizing in Western cultures.
The genetic variation affects the way people perceive the smell and taste of cilantro, making it seem soapy, metallic, or grassy to those who are sensitive to it. This is because the aldehyde chemicals in cilantro bind to the olfactory receptors in a way that is different from other people, triggering a strong and unpleasant response. Interestingly, this genetic variation is not the only factor that determines whether someone likes or dislikes cilantro, as cultural and environmental factors also play a significant role. However, for many people, the genetic variation is a key factor in their dislike of the herb, and it may be why they find it so gross.
Is it true that cultural background plays a role in shaping people’s attitudes towards cilantro?
Yes, cultural background plays a significant role in shaping people’s attitudes towards cilantro. In many Asian and Latin American cultures, cilantro is a staple herb and is often used liberally in cooking. In these cultures, people are exposed to cilantro from a young age and tend to develop a taste for it. In contrast, in many Western cultures, cilantro is not as commonly used and may be seen as an exotic or unusual ingredient. This lack of exposure can contribute to a greater dislike of the herb, as people may be more likely to find its flavor and aroma unfamiliar and unpleasant.
The cultural significance of cilantro can also influence people’s attitudes towards it. For example, in some cultures, cilantro is seen as a symbol of freshness and vitality, while in others it may be associated with traditional cuisine and nostalgia. These cultural associations can shape people’s perceptions of the herb and influence their willingness to try it. Additionally, the way cilantro is prepared and used in different cultures can also affect people’s attitudes towards it. For example, in some cultures, cilantro is used in small quantities as a garnish, while in others it is used in larger quantities as a main ingredient. These differences in preparation and usage can affect the overall flavor and aroma of the herb, which can in turn influence people’s opinions of it.
Can people who dislike cilantro learn to like it?
Yes, it is possible for people who dislike cilantro to learn to like it. While the genetic variation that affects people’s perception of cilantro cannot be changed, people’s tastes and preferences can be influenced by cultural and environmental factors. For example, people who are exposed to cilantro in different contexts and preparations may find that they develop a taste for it over time. Additionally, people’s attitudes towards cilantro can be influenced by social and cultural norms, so if they are part of a social group that values and enjoys cilantro, they may be more likely to try it and develop a taste for it.
However, it’s worth noting that people’s preferences for cilantro are often deeply ingrained and can be difficult to change. For people who have a strong dislike of cilantro, it may take a significant amount of time and exposure to the herb in different contexts for them to develop a taste for it. Additionally, people’s perceptions of cilantro can be influenced by a range of factors, including their personal experiences, cultural background, and individual preferences. As a result, it’s unlikely that everyone who dislikes cilantro will learn to like it, and that’s okay. There are many other herbs and ingredients that people can enjoy, and there’s no need to force someone to like cilantro if they genuinely dislike it.
What are some common misconceptions about cilantro?
One common misconception about cilantro is that it is a acquired taste, and that people who dislike it simply haven’t tried it enough. While it’s true that people’s tastes and preferences can change over time, the genetic variation that affects people’s perception of cilantro is a significant factor in determining their dislike of the herb. Another misconception is that cilantro is a polarizing herb because of its strong flavor, but the truth is that the flavor of cilantro is relatively mild and is often used to add depth and freshness to dishes.
Another misconception about cilantro is that it is a useless herb, and that it doesn’t add any significant nutritional or culinary value to dishes. However, cilantro is a rich source of vitamins A and K, and it also contains antioxidants and other nutrients that can help to protect against chronic diseases. In terms of culinary value, cilantro is a versatile herb that can be used in a wide range of dishes, from salads and sauces to curries and stir-fries. Its unique flavor and aroma can add depth and freshness to many different types of cuisine, making it a valuable ingredient for many chefs and home cooks.
Is cilantro a divisive herb in all cultures?
No, cilantro is not a divisive herb in all cultures. While it’s true that cilantro is polarizing in many Western cultures, it is a staple herb in many Asian and Latin American cultures, where it is widely used and enjoyed. In these cultures, cilantro is often seen as a fresh and vibrant ingredient, and it is commonly used to add flavor and aroma to a wide range of dishes. In fact, in some cultures, cilantro is considered an essential ingredient, and it is often used in traditional recipes and dishes.
The cultural significance of cilantro can vary widely from one culture to another, and it’s interesting to note that the herb is not always polarizing. In many cultures, cilantro is seen as a neutral or positive ingredient, and it is often used in cooking without controversy. For example, in Indian cuisine, cilantro is a common ingredient in chutneys and sauces, while in Mexican cuisine, it is often used to add flavor to salsas and salads. In these cultures, cilantro is not seen as a divisive herb, but rather as a useful and delicious ingredient that can add flavor and freshness to many different types of dishes.
Can the dislike of cilantro be related to other food preferences?
Yes, the dislike of cilantro can be related to other food preferences. Research has shown that people who dislike cilantro are more likely to dislike other foods that contain similar aldehyde chemicals, such as Brussels sprouts and blue cheese. This suggests that the genetic variation that affects people’s perception of cilantro may also influence their preferences for other foods. Additionally, people’s attitudes towards cilantro can be influenced by their overall food preferences and dietary habits, so people who tend to prefer milder flavors may be more likely to dislike cilantro.
The relationship between cilantro preference and other food preferences is complex, and more research is needed to fully understand the underlying factors. However, it’s clear that people’s preferences for cilantro are influenced by a range of factors, including genetics, culture, and personal experience. By studying the relationship between cilantro preference and other food preferences, researchers may be able to gain a better understanding of the underlying mechanisms that drive food preferences and develop new strategies for promoting healthy eating habits. Additionally, understanding the relationship between cilantro preference and other food preferences can help to promote greater appreciation and acceptance of different foods and cuisines.
