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.

A new study challenges the belief that seed oils are harmful by showing that they may lower inflammation and improve cardiovascular health. The research was presented at the NUTRITION 2025 conference in Orlando, Florida, and carries meaningful implications for Thai consumers amid ongoing discussions about cooking oils and chronic disease.
