#SeedOils

A new scientific study has overturned a widespread dietary myth, revealing that consuming seed oils like soybean and corn oil may actually lower inflammation and improve heart health—contrary to persistent claims suggesting otherwise. The findings, presented at the prestigious NUTRITION 2025 conference in Orlando, Florida, are highly relevant for Thai consumers amid ongoing debates about cooking oil safety and chronic disease in the Kingdom.

Seed oils, including commonly used vegetable oils rich in linoleic acid—a type of omega-6 fatty acid—have become controversial, with vocal critics suggesting they may promote inflammation and contribute to the country’s rising rates of heart disease and diabetes. These oils are common kitchen staples in Thai households and are found in a variety of popular foods, from street-side stir fries to commercial packaged snacks.

The recent Make America Healthy Again campaign has ignited fresh debate over the dietary role of seed oils, urging Americans to eliminate these oils for better health—a message now resonating with health-conscious audiences in Thailand. The campaign claims that removing commonly used seed oils, such as soybean, corn, sunflower, canola, and cottonseed oils, from the everyday diet can lead to improved heart health, lower rates of chronic illness, and a return to traditional eating habits—a stance backed by some nutrition advocates but challenged by leading health organizations.
