The seed oil panic is hurting my cardiac patients

16 hours ago

A clinical dietitian observes a trend where patients are shifting from vegetable oils to saturated fats like beef tallow due to panic over seed oils.
The seed oil panic has gained institutional support, influencing dietary guidelines and prompting food companies to reformulate products.
'Seed oils' is a marketing term; vegetable oils with polyunsaturated fats are linked to reduced cardiovascular risk when replacing saturated fats.
Claims that linoleic acid in seed oils causes inflammation or that oxidation from cooking harms health lack robust human trial evidence.
The problem with ultra-processed foods is their engineering to override satiety, not specifically the seed oils used in them.
Beef tallow contains high levels of saturated and ruminant trans fats, which are associated with cardiovascular risks.
The 2026 dietary guidelines ironically recommend oils with essential fatty acids but list fats like butter and tallow, which are poor sources.
The seed oil panic benefits the beef and dairy industries, aligning with their long-term lobbying to rehabilitate saturated fats.
Food industry reforms often just swap fats in ultra-processed products without making them healthier overall.
The evidence-supported approach is boring: eat more vegetables and legumes, less ultra-processed food, and default to olive oil, focusing on overall dietary patterns.
