Seed oils have been painted as villains in recent diet debates, with critics labeling them toxic and blaming them for a spike in inflammation-related health issues. Influencers have taken up the charge, targeting canola, corn, peanut, soybean, sunflower, and grapeseed oils as dietary culprits. However, experts argue that this anti-seed oil hype misses the bigger picture: the problem isn’t the oils themselves, but how much we’re consuming.
According to *EatingWell*, many of these claims stem from poorly designed studies or influencers echoing unverified information. Gastroenterologist and social media educator Will Bulsiewicz recently addressed the issue, emphasizing that seed oils can contribute to inflammation only when consumed excessively — especially in the form of fried and ultra-processed foods. “The real issue is overconsumption,” he explained, pointing out that too many calories paired with insufficient fiber intake lead to health problems, not the oils in isolation.
A recent narrative review published in the *British Journal of Nutrition* adds weight to this perspective. Researchers analyzed evidence comparing poly- and monounsaturated fats to saturated fats, concluding that omega-6 polyunsaturated oils (n-6 PUFAs) like those in sunflower and peanut oils are not harmful. On the contrary, they appear to benefit heart health. Lead author Kristina Petersen, Ph.D., a nutritional sciences professor at Penn State, highlighted that linoleic acid — a key component of n-6 oils — is linked to a lower risk of heart disease and does not increase inflammation or oxidative stress, according to clinical trials.
The key takeaway from experts? Focus on moderation and avoid overloading your diet with saturated fats. Petersen reassures that the average American’s oil intake aligns with heart health recommendations, so there’s no need to panic.
While some may question the review’s funding sources, including organizations like the United Soybean Board and the National Corn Growers Association, these findings align with prior research. The advice is clear: balance your diet and prioritize healthier sources of seed oils. And maybe go easy on the french fries.
