Discover the Surprising Health Benefits of Seed Oils, Backed by New Research

Seed oils have recently garnered a negative reputation, often being blamed for promoting inflammation and contributing to chronic illnesses and cancer due to their high omega-6 fatty acid content. Oils such as canola, corn, sunflower, and safflower are frequently cited as culprits in these claims. However, many medical professionals have disputed these assertions, and a groundbreaking study now suggests that seed oils might, in fact, offer anti-inflammatory benefits.

The term “hateful eight” is sometimes used to describe seed oils, a label that may stem from their presence in many processed foods. These foods have been linked to increased rates of colon cancer in younger populations. It’s important to note that processed foods also contain other unhealthy components, such as added sugars and saturated fats, which may contribute to these health concerns.

Research has previously suggested that omega-6 fatty acids, abundant in seed oils, possess inflammatory properties that could potentially promote tumor growth in colon cancer. Yet, the recent study aimed to delve deeper into the effects of linoleic acid (LA), a specific omega-6 fatty acid found in seed oils, on inflammation.

In this study, researchers analyzed blood samples from 2,700 individuals to measure levels of LA and arachidonic acid (AA), another omega-6 fatty acid. They also assessed 10 biomarkers related to inflammation to determine how LA and AA influenced them.

Interestingly, the findings revealed that higher levels of LA and AA were associated with lower levels of five and four of the 10 biomarkers, respectively. Moreover, neither LA nor AA was linked to elevated levels of any inflammatory biomarker.

The belief that omega-6 fatty acids drive inflammation is often contrasted with the well-documented anti-inflammatory properties of omega-3s. It is commonly suggested that diets rich in omega-6s might be deficient in omega-3s. Nonetheless, a study published in the International Journal of Cancer last year indicated that both omega-3 and omega-6 fatty acids could reduce the risk of 19 different types of cancer. Specifically, omega-6s were found to lower the incidence of cancers in various organs, including the head and neck, esophagus, stomach, colon, and others.

“Omega-6 is a polyunsaturated fat the body needs but cannot produce itself, so it must get it from foods. Polyunsaturated fats help the body reduce bad cholesterol, lowering the risk for heart disease and stroke,” experts say, advocating for the inclusion of omega-6s in a balanced diet.

This new research challenges the negative perception of seed oils, suggesting that their omega-6 content might not be as harmful as previously thought. Instead, these oils could play a beneficial role in reducing inflammation and supporting overall health.
