Seed oils, such as rapeseed, sunflower, and safflower oil, are prevalent in the modern diet. They are used in a variety of products, from cooking oils to processed foods. However, there is a growing concern about the health implications of consuming these oils. Many people believe that seed oils can cause inflammation and contribute to various diseases.
In this article, we will explore the truth behind the fear surrounding seed oils with the help of Professor Sarah Berry, an expert in nutritional sciences at King’s College London and Chief Scientist at ZOE. Professor Berry will dispel myths and provide valuable insights into navigating a world filled with seed oils.
Seed oils are extracted from the seeds of plants like sunflowers, safflowers, and corn. They are a significant source of dietary fat and are commonly used in cooking and food production. While seed oils have their benefits, such as a high smoke point and neutral taste, they have come under scrutiny for their potential link to inflammation and disease.
Critics of seed oils argue that their high omega-6 fatty acid content can trigger inflammation in the body, leading to a range of health issues, including diabetes, heart disease, and cancer. However, Professor Berry challenges this notion, stating that not all seed oils are harmful to health. In fact, most vegetable oils, including seed oils, are a type of seed oil.
Despite the negative connotations surrounding seed oils, they are found in many ultra-processed foods and are a staple in modern diets. It is essential to understand that not all seed oils are created equal and that demonizing them as unhealthy may be misguided.
One common misconception is that all oils are inherently unhealthy. However, Professor Berry stresses that this is not the case. While some oils may be less beneficial than others, demonizing all oils overlooks the nuanced role they play in a balanced diet.
In conclusion, seed oils are a complex topic that requires a nuanced understanding. While some seed oils may have negative health implications, not all seed oils are harmful. It is crucial to approach this topic with an open mind and rely on evidence-based research to make informed decisions about dietary fat intake. By educating ourselves and seeking guidance from experts like Professor Sarah Berry, we can navigate the world of seed oils with confidence and clarity. Canola oil, known as rapeseed oil in other parts of the world, is a commonly used seed oil in the United States and North America. However, it is important to note that the names may vary depending on the country, but the oil itself remains the same.
In addition to canola oil, soybean oil is another popular seed oil in both the U.S. and North America, followed by sunflower oil. Other seed oils such as sesame seed oil, corn seed oil, and others are also consumed in smaller quantities.
The process of making seed oils is relatively straightforward. The oil is extracted from the seeds through methods such as cold-pressing or solvent extraction. Cold-pressed oils are obtained by simply squeezing the seeds, while solvent extraction involves the use of chemicals like hexane to maximize oil extraction efficiency. Further processing steps such as bleaching and deodorization are often used to remove minor components and ensure the stability of the oil.
While some argue that refined seed oils may have lost some of their phytonutrients and polyphenols compared to cold-pressed oils, research suggests that the differences are minimal. The end product of refined seed oils is still primarily the oil itself, with no harmful chemicals added.
Seed oils are valued not only for their fatty acid composition but also for their phytonutrients and micronutrients such as vitamin E and phytosterols. While refined oils may have slightly lower levels of these beneficial compounds, the overall nutritional impact is considered to be minor.
In terms of cost, cold-pressed oils are often more expensive due to the labor-intensive extraction process. However, the health benefits of cold-pressed oils over refined oils are not significant enough to justify the higher cost for most consumers.
Overall, the consumption of seed oils in the U.S. and North America has increased significantly over the past few decades. Whether consumed directly or added to processed foods, seed oils play a significant role in the modern diet, providing essential fatty acids and other nutrients for optimal health. vitamins or minerals. So they’re these other compounds that are found in plant-based foods that have these health benefits.
And so when we’re looking at seed oils, we’re not just looking at the fatty acid composition, but we’re also looking at these other compounds that are present in the oil that can also have a beneficial impact on our health.
Now, when we’re talking about the different seed oils, as I mentioned earlier, soybean oil and rapeseed oil are high in monounsaturated and polyunsaturated fatty acids. This makes them a healthier option compared to oils that are high in saturated fats.
On the other hand, sunflower oil has a particularly high level of polyunsaturated fatty acids. This makes it a good option for those looking to increase their intake of polyunsaturated fats in their diet.
However, it’s important to note that while polyunsaturated fats are generally considered healthier than saturated fats, the type of polyunsaturated fats also matter. There are two main types of polyunsaturated fats – omega-3 and omega-6 fatty acids.
Omega-3 fatty acids, found in fatty fish like salmon and mackerel, are known for their anti-inflammatory properties and are considered beneficial for heart health. On the other hand, omega-6 fatty acids, found in high amounts in many seed oils, can be pro-inflammatory when consumed in excess.
Therefore, when choosing a seed oil to incorporate into your diet, it’s important to consider not only the overall fatty acid composition but also the specific types of fatty acids present in the oil.
Additionally, as mentioned earlier, the presence of phytonutrients in seed oils can also contribute to their health benefits. Polyphenols, for example, are antioxidants that can help protect cells from damage caused by free radicals.
So, next time you’re reaching for a bottle of vegetable oil or sunflower oil, take a moment to consider not only the fatty acid composition but also the presence of these other beneficial compounds that can contribute to your overall health and well-being.
Seed oils are a hot topic of debate in the health and nutrition world. Many people are confused about whether seed oils are good for us or if they are harmful to our health. In a recent podcast discussion between Jonathan Wolf and Professor Sarah Berry, they delved into the topic of seed oils and debunked some common myths surrounding them.
Seed oils are rich in fatty acids, including monounsaturated and polyunsaturated fatty acids. These oils also contain compounds that may have health-promoting effects. For example, extra virgin olive oil is known for its high levels of polyphenols, which have been linked to various health benefits. Similarly, seed oils like rapeseed, canola, and soybean oil contain high levels of monounsaturated fatty acids, making them stable for cooking.
One common concern about seed oils is their smoke point, which is the temperature at which the oil starts to smoke and degrade. Oils with higher levels of monounsaturated fatty acids, like rapeseed and canola oil, have a higher smoke point compared to oils rich in polyunsaturated fatty acids, such as sunflower oil. This makes them more suitable for cooking at high temperatures.
Despite the nutritional benefits of seed oils, there is a lot of misinformation circulating about their potential harmful effects. Professor Sarah Berry addressed some of the common arguments against seed oils, including the claim that they are toxic and can cause various health issues. She also debunked the idea that seed oils create an unfavorable omega-6 to omega-3 ratio, leading to inflammation.
Another argument against seed oils is that they undergo a refining process that makes them unnatural and potentially harmful. However, Professor Sarah Berry emphasized that this processing does not make seed oils toxic or dangerous for consumption. Additionally, concerns about seed oils being prone to oxidation when heated were addressed, with Professor Sarah Berry explaining that proper cooking techniques can help mitigate this risk.
In conclusion, seed oils can be a healthy addition to a balanced diet when consumed in moderation and used appropriately for cooking. Debunking common myths and understanding the nutritional benefits of seed oils can help individuals make informed decisions about their dietary choices. how long you’re eating these oils for, how much you’re eating, and many other factors can influence this. But what we do know is that having a higher intake of omega-6 is beneficial for heart health. And this is all the more reason to not demonize seed oils as toxic substances.
In fact, seed oils have been consumed for centuries in various cultures around the world. They are a rich source of essential fatty acids that our bodies need for various functions. Omega-6 fatty acids play a crucial role in brain function, skin health, and inflammation regulation. They are also important for hormone production and immune system function.
While it is true that excessive consumption of seed oils, especially in processed foods, can lead to health issues, it is not the oils themselves that are the problem. It is the overall diet and lifestyle that need to be considered. Moderation is key when it comes to any type of food, including seed oils.
It is important to focus on a balanced diet that includes a variety of fats, including omega-3 and omega-6 fatty acids. Consuming a variety of oils, such as olive oil, avocado oil, and coconut oil, in addition to seed oils, can provide a well-rounded intake of essential nutrients.
So the next time you see claims that seed oils are toxic, take a closer look at the science behind it. While it is always important to be mindful of your dietary choices, demonizing a whole food group based on limited data is not the solution. Seed oils can be a part of a healthy diet when consumed in moderation and as part of a balanced lifestyle. Omega-3 and omega-6 fatty acids are essential nutrients that our bodies cannot produce on their own. This means that we must obtain these fatty acids through our diet in order to maintain optimal health. The distinction between omega-3 and omega-6 lies in their structure and health effects.
Omega-3 fatty acids, such as alpha-linolenic acid (ALA), can be converted by enzymes in the body into very long-chain versions called EPA and DHA. These long-chain versions have been shown to have numerous health benefits, including anti-inflammatory and anti-coagulatory properties. In contrast, omega-6 fatty acids, like linoleic acid, can be converted into arachidonic acid, which produces chemicals with more pro-inflammatory and pro-coagulatory properties.
The balance between omega-3 and omega-6 fatty acids is often a topic of discussion, with some suggesting that a higher intake of omega-3 compared to omega-6 is ideal for health. However, research has shown that increasing omega-6 intake does not necessarily lead to increased inflammation or coagulation in the body. Our bodies have complex mechanisms in place to regulate the conversion of these fatty acids and their effects on our health.
It is important to note that individual responses to omega-3 and omega-6 fatty acids may vary. While the majority of the population may benefit from increasing their intake of polyunsaturated fatty acids, there is a small percentage of individuals who may be genetically predisposed to negative effects from high omega-6 consumption.
Overall, the evidence suggests that omega-6 fatty acids are beneficial for health when consumed as part of a balanced diet. By understanding the role of omega-3 and omega-6 fatty acids in the body, we can make informed decisions about our dietary choices to support optimal health and well-being. Seed oils high in polyunsaturated fatty acids, such as omega-3 and omega-6, have been a topic of much debate in the world of nutrition. In a recent podcast discussion between Professor Sarah Berry and Jonathan Wolf, they delved into the myths and facts surrounding these oils and their impact on our health.
Professor Sarah Berry explained that polyunsaturated fatty acids are also known as essential fatty acids because our bodies cannot produce them, so we must obtain them from our diet. This is why dietary guidelines emphasize the importance of consuming these essential fatty acids. The good news is that because we cannot make these fatty acids, we can accurately measure how much of them people are getting in their diet by analyzing their tissue levels.
One common misconception about these oils is that they are unnatural due to the refining process they undergo. However, based on current evidence, there doesn’t seem to be any downside to the processing of these oils except for a potential loss of some beneficial compounds. Another myth is that these oils are prone to oxidation, especially when heated, leading to the production of toxic compounds. But Professor Berry shared the results of a study she conducted that showed that heating seed oils multiple times did not lead to significant oxidative damage.
Jonathan Wolf raised the question of the omega-3 and omega-6 ratio and whether it truly matters. Professor Berry clarified that as long as one consumes a sufficient amount of omega-3 fatty acids, the ratio of omega-6 to omega-3 may not be as critical as previously thought. The key takeaway is to focus on increasing overall intake of healthy oils rather than fixating on the omega-6 content alone.
In conclusion, the discussion highlighted that consuming polyunsaturated fatty acids from seed oils can be beneficial for our health when done in moderation and as part of a balanced diet. It’s important to debunk the myths surrounding these oils and focus on practical advice for improving our overall health through dietary choices. Seed oils have been a topic of debate for many years, with conflicting information on their health benefits and risks. However, a recent study conducted by Professor Sarah Berry shed some light on the topic. In the study, participants were fed reheated, refried fat after 10 days of repeated frying in high-temperature oil. The purpose of the study was to determine the effects of this reheated oil on oxidative compounds and blood vessel function.
Surprisingly, the study found that there was no significant difference between the fresh oil and the reheated oil in terms of oxidative compounds or blood vessel function. This led Professor Berry to conclude that, in real life, the type of oil used for frying may not have a significant impact on health outcomes. However, she did caution against repeated frying with the same oil over an extended period, recommending the use of fresh oil whenever possible.
When it comes to choosing cooking oils, Professor Berry emphasized the importance of personalized recommendations based on individual health needs. For individuals with high cholesterol, she recommended using high polyunsaturated fatty acid oils such as sunflower oil, which has been shown to lower LDL cholesterol levels. Additionally, she highlighted the benefits of extra virgin olive oil, which is rich in monounsaturated fatty acids and polyphenols.
In terms of commercial food products, Professor Berry pointed out that about 60% of seed oils come from processed foods, making it difficult to control their intake. However, she stressed that the concern lies more with the other ingredients in these foods rather than the seed oils themselves. She encouraged consumers to be mindful of the oils they use for cooking and to consider making swaps to oils with higher polyunsaturated fatty acid content for added health benefits.
Overall, Professor Berry’s research suggests that while seed oils may not be as harmful as previously thought, there is still room for improvement in terms of choosing healthier cooking oils and being aware of the presence of seed oils in processed foods. By making informed choices and incorporating a variety of oils into their diets, individuals can optimize their health and well-being. Seed oils have been a topic of discussion in the health and nutrition world for quite some time now. With various types of oils available, it can be confusing to determine which ones are the best for our health. In a recent study comparing seed oils to tropical oils like palm oil and coconut oil, it was found that seed oils had a more favorable impact on blood lipids, particularly LDL cholesterol.
One particular seed oil that has gained attention is soybean oil. In the United States, a significant portion of soybean oil undergoes a process called full hydrogenation, where it is converted from a liquid oil to a hard fat. This process is often used in food applications like cakes, pastries, and biscuits, where a solid fat is needed. While the hydrogenation process does not produce trans fats like partial hydrogenation does, it does convert unsaturated fatty acids into saturated fatty acids.
Research has shown that soybean oil in its natural state, without undergoing full hydrogenation, is better for health than hydrogenated soybean oil. However, it is essential to note that hydrogenated soybean oil does not have an unfavorable effect based on current evidence. It is still considered safe for consumption, but the natural form of soybean oil is preferred.
When it comes to cooking with seed oils, there is a common concern about heating them to high temperatures. If a seed oil is heated above its smoke point and starts to smoke, it may lose some of its beneficial compounds like vitamin E, polyphenols, and phytosterols. However, it does not immediately become harmful to consume. The worst-case scenario is that the oil may taste unpleasant, but it is not a health risk.
In conclusion, seed oils, including soybean oil, are generally considered to be healthier options compared to tropical oils like palm oil and coconut oil. While full hydrogenation of soybean oil is common in the U.S. food industry for certain applications, it is still recommended to choose natural, unprocessed seed oils for optimal health benefits. Cooking with seed oils at high temperatures may result in some loss of nutrients, but it does not pose a significant health risk. It is essential to make informed choices about the oils we use in our cooking and food preparation to promote overall health and well-being. Seed oils have become a staple in our diets over the last 50 years, with a significant portion of our intake coming from processed and ultra-processed foods. These oils, derived from crushing seeds to extract the oil, contain different types of fatty acids that play a crucial role in our health.
There are three main groups of fatty acids: saturated, monounsaturated, and polyunsaturated. Saturated fats, found in red meat and butter, have no double bonds and are considered the least healthy. Monounsaturated fats have one double bond, while polyunsaturated fats have two or more double bonds, making them the healthiest option. Both monounsaturated and polyunsaturated fats have been shown to have positive effects on our health when consumed in appropriate amounts.
Within polyunsaturated fats, there are two essential fatty acids: omega-6 and omega-3. These essential fatty acids are crucial for our health, as our bodies cannot produce them on their own. It is important to include these fats in our diets to ensure optimal health and prevent deficiencies.
Contrary to popular belief, the increase in seed oil consumption over the past few decades is not the root cause of the decline in our health. In fact, consuming more omega-6 fats from seed oils has been linked to a reduced risk of heart disease. It is essential to understand the role of different fats in our diet and make informed choices based on our health goals.
When it comes to choosing the best oil for your health, extra virgin olive oil is recommended for its cholesterol-lowering properties. It is a flavorful option that can enhance the taste of dishes. Sunflower oil is another good choice for its neutral flavor, making it suitable for a wide range of dishes. While avocado oil may be popular, there is limited evidence to support its health benefits compared to other oils like canola or rapeseed oil.
In conclusion, understanding the different types of fats and their roles in our health is essential for making informed choices about our diets. While seed oils have become a common ingredient in many processed foods, they can be part of a healthy diet when consumed in moderation. By incorporating a variety of oils rich in monounsaturated and polyunsaturated fats, we can support our overall health and well-being. Omega-6 and omega-3 oils have been a topic of discussion in the health and wellness community for quite some time now. In a recent podcast, Professor Sarah Berry shed some light on the benefits and myths surrounding these essential fatty acids.
It was mentioned that omega-6 can reduce the risk of heart disease by up to 30%, while omega-3 is even better for heart health. Omega-3 is known for its anti-inflammatory properties, which can benefit many chronic conditions that are linked to inflammation.
Despite the high ratio of omega-6 to omega-3 in seed oils, it was emphasized that the processing of these oils, especially if they are not cold-pressed, does not significantly impact their healthful properties. In fact, in real-life tests, there was no noticeable difference in the end result of these oils.
Furthermore, heating these oils above their smoke point was deemed harmless, with the only consequence being a slight change in taste. Repeatedly using oil that has reached its smoke point is not encouraged, but using it once for cooking is not a cause for concern.
When it comes to choosing cooking oils, soybean and sunflower oil were recommended as good options, while canola or rapeseed oil may not be as beneficial. Extra virgin olive oil was highlighted as the best option for optimal health, except in cases where its taste may not complement the dish.
On the topic of palm oil, Professor Sarah Berry expressed her concerns about its impact on health, noting that it is not as beneficial as other oils. Palm oil is often used as a hard fat in products, similar to fully hydrogenated soybean oil in the U.S. Both of these oils are not as good for health before they undergo treatment.
In conclusion, making informed choices about the types of oils we use for cooking can have a significant impact on our overall health. By opting for healthier oils like extra virgin olive oil and avoiding oils with lower nutritional value like palm oil, we can take a step towards improving our well-being. It is essential to consider the processing, smoke point, and overall health benefits of different oils to make the best choices for our health. Seed oils have long been a topic of controversy in the health and wellness community. Some believe that they are toxic and should be avoided at all costs, while others argue that they can be a valuable part of a healthy diet. In a recent podcast interview, Professor Sarah Berry shed some light on the topic and shared some surprising insights.
Professor Berry emphasized that seed oils, when consumed in moderation and in their pure form, can actually be quite beneficial for our health. While extra virgin olive oil may have some additional health benefits due to its unique compounds, randomized control trials have shown that seed oils can perform nearly as well as olive oil in many outcomes.
One of the major concerns surrounding seed oils is their impact on cholesterol levels. However, Professor Berry explained that for the majority of people, incorporating seed oils into their diet can actually help reduce cholesterol and have a positive long-term effect on their health.
It is important to note that not all seed oils are created equal. It is crucial to choose high-quality, cold-pressed seed oils that are free from additives and heavily processed ingredients. By swapping out unhealthy fats like those found in cakes and pastries for nutritious seed oils, individuals can make a positive impact on their overall health.
In conclusion, the evidence overwhelmingly supports the idea that seed oils are not as harmful as they are often portrayed to be. While there may be some conflicting information out there, it is clear that incorporating seed oils into a balanced diet can have numerous health benefits. So before you dismiss seed oils entirely, consider giving them a second look and see how they can complement your overall wellness journey.

The Rise of Veganism: A Shift Towards a More Compassionate Lifestyle
In recent years, there has been a significant rise in the number of people choosing to adopt a vegan lifestyle. Veganism, which involves abstaining from consuming any animal products, has gained popularity for a variety of reasons, including concerns about animal welfare, environmental sustainability, and personal health.
One of the primary reasons why people are turning to veganism is out of a sense of compassion for animals. Many individuals are becoming increasingly aware of the harsh realities of factory farming and the suffering that animals endure in order to produce meat, dairy, and eggs. By choosing to go vegan, these individuals are taking a stand against animal cruelty and advocating for a more compassionate way of living.
Another driving factor behind the rise of veganism is the growing awareness of the environmental impact of animal agriculture. The meat and dairy industries are major contributors to deforestation, water pollution, and greenhouse gas emissions. By opting for a plant-based diet, vegans are reducing their carbon footprint and helping to combat climate change.
In addition to concerns about animal welfare and the environment, many people are also turning to veganism for health reasons. Research has shown that a plant-based diet can lower the risk of chronic diseases such as heart disease, diabetes, and certain types of cancer. Vegan diets are typically high in fiber, vitamins, and antioxidants, which can help to boost overall health and well-being.
The rise of veganism has been accompanied by a surge in the availability of vegan products and options. Supermarkets, restaurants, and food companies are increasingly catering to the growing demand for plant-based alternatives to traditional animal products. From vegan meat substitutes to dairy-free cheeses and plant-based milks, there are now more options than ever for those looking to make the switch to a vegan lifestyle.
As veganism continues to gain traction, it is clear that this is more than just a passing trend. It represents a shift towards a more compassionate, sustainable, and healthier way of living. By choosing to go vegan, individuals are not only making a positive impact on the world around them but also taking a stand for what they believe in. Whether motivated by concerns about animal welfare, the environment, or personal health, those who embrace veganism are contributing to a more compassionate and ethical world for all living beings.
