In 2025, the term “seed oils” has gained prominence, although it may not have been on your radar just a year or two ago. Influencers in the wellness space are now cautioning against the consumption of certain oils, dubbed the “Hateful Eight”: canola, corn, cottonseed, grapeseed, rice bran, safflower, soybean, and sunflower oil. This concern was echoed by Robert F. Kennedy Jr., who has been nominated as the health and human services secretary by President-elect Donald Trump, suggesting that Americans are unknowingly harmed by these seed oils.
Recently, a humorous take on this trend circulated on TikTok, where a person jokingly emphasized the importance of avoiding seed oils while cooking with mini bottles of Fireball Cinnamon Whisky. Some changes are being made in response to these concerns, with Sweetgreen’s CEO announcing the launch of a seed oil-free menu to offer guests healthier options.
However, nutrition experts view the current focus on seed oils as a recycled wellness trend that has resurfaced over the years. Dr. Dariush Mozaffarian from Tufts University’s Food Is Medicine Institute pointed out that this issue has been discussed periodically for the past two decades. The emphasis on seed oils, according to experts like Christopher Gardner from Stanford Prevention Research Center, largely centers around the ratio of omega-6 to omega-3 fatty acids. This concern stems from the belief that an imbalance in this ratio could lead to inflammation and contribute to chronic conditions like heart disease or diabetes.
While the debate around seed oils continues, it is important to consider the broader context of how different fatty acids impact health. Both omega-6s and omega-3s play a role in various bodily processes related to inflammation and overall health. Despite the ongoing discussions and warnings, the scientific evidence supporting the benefits of omega-6s, particularly in cardiovascular health, remains significant.
“Omega-3s are considered to be less inflammatory than omega-6s,” stated Gardner. “While there are some omega-6 byproducts that may contribute to inflammation in some way, the overall effect is not strongly pro-inflammatory. However, omega-6s also offer health benefits. Numerous randomized controlled trials have shown that omega-6s can improve various aspects of blood cholesterol levels, such as increasing HDL cholesterol, reducing LDL cholesterol, lowering triglycerides, and enhancing glucose and insulin levels,” explained Mozaffarian. “Contrary to popular belief, omega-6 fatty acids have been shown to improve glucose levels, insulin resistance, and insulin secretion in randomized trials. They are highly beneficial for overall health.”
Focusing solely on omega-3s and omega-6s is not the most effective way to determine a food’s healthiness, Gardner emphasized. “The crucial factor is whether the fat is saturated or unsaturated,” he explained. Omega-3s and omega-6s belong to the category of unsaturated fats, specifically polyunsaturated fatty acids. Research indicates that consuming polyunsaturated fats instead of saturated fats can reduce the risk of heart disease, as most saturated fats come from animal products like meat and dairy. The main sources of saturated fats in the American diet include cheese, pizza, ice cream, and eggs.
“It’s relatively insignificant whether it’s omega-6 or omega-3,” Gardner noted. “Both are beneficial for health.” Experts caution that while some criticisms of seed oils are valid, they may be misguided. The rise in seed oil consumption in America is accompanied by an increase in fast food and heavily processed foods, which often contain significant amounts of seed oil. The issue may not solely lie with seed oils but also with the excessive intake of refined carbohydrates, salt, and sugar present in the American diet.
Rather than fixating on a particular nutrient, it is more constructive to examine overall dietary habits, suggested Alice Lichtenstein, a nutrition science professor at Tufts University. Dietary patterns, such as those rich in fish, are linked to reduced cardiovascular disease risk, likely due to lower saturated fat intake and higher monounsaturated fat consumption. People who consume fish tend to engage in other healthy behaviors, like being more physically active and avoiding smoking. Healthful habits tend to reinforce one another, just as unhealthy habits can compound. Lichtenstein emphasized the importance of considering the broader dietary context rather than isolating specific nutrients when assessing health outcomes.
**Uncovering the Controversy Surrounding Seed Oils: A Deeper Dive**
In the realm of nutrition, the debate surrounding seed oils has sparked a wave of discussion among experts and consumers alike. Is there any substantial harm in steering clear of these commonly used oils? While some argue that avoiding seed oils carries no inherent health risks, there are nuanced downsides that merit consideration.
The choice to shun seed oils entirely may not be as straightforward as it seems. Registered dietitian Julia Zumpano sheds light on the practical challenges associated with such a dietary shift. Cooking all meals at home to avoid seed oils means dedicating significant time to meal preparation, encompassing everything from salad dressings to sauces and even bread. For many in the hustle and bustle of daily life, this level of culinary commitment may be a daunting task.
Zumpano’s personal experience underscores the effort required to ensure her children are not exposed to the processed foods often prevalent in sports settings. While her intent is not solely to sidestep seed oils, the byproduct of steering clear of processed fare inadvertently results in limiting seed oil consumption.
However, the reality remains that not all parents can afford the luxury of meticulously planning and packing fresh, homemade meals. Budgetary constraints often dictate culinary choices, with seed oils proving to be a more economical option than premium alternatives like olive or avocado oil, which boast healthier fat profiles.
Moreover, taste preferences and culinary considerations come into play when deliberating the use of oils in cooking. Chef Gardner highlights the necessity of neutral oils for certain dishes, emphasizing the importance of selecting oils that complement the flavors of a particular recipe. The culinary landscape is diverse, and the choice of oil can significantly impact the taste and texture of a dish.
The crux of the issue lies not in the avoidance of seed oils per se, but in the potential ramifications of substituting them with less healthy alternatives. Nutrition experts caution against a knee-jerk reaction to eliminating seed oils without a thoughtful consideration of what might replace them. The fear is that a blanket rejection of seed oils could inadvertently lead to a surge in the use of animal fats, such as butter, lard, or beef tallow, which are higher in saturated fats linked to cardiovascular issues and weight gain.
Dr. Mozaffarian underscores the importance of informed decision-making in dietary choices. While acknowledging the pitfalls of seed oils, he warns against a wholesale shift to alternatives that may pose greater health risks. The emphasis is on educating consumers about the broader context of healthy eating habits, steering clear of highly processed foods laden with sugar, salt, and unhealthy fats.
Ultimately, the seed oil debate serves as a microcosm of the broader discourse on nutrition and dietary choices. It prompts us to delve into the nuances of food selection, mindful of the impact on our health and well-being. As we navigate the complex terrain of modern diets, striking a balance between convenience, taste, and nutrition remains a paramount concern.
