About

What it is and where it shows up.

Vegetable oil is a broad category of edible fats extracted from plant sources (seeds, nuts, fruits) such as soybean, sunflower, canola, palm, and groundnut; it is used extensively in cooking, frying, baking, and food manufacturing as a fat/energy source and texture modifier. Common unhydrogenated forms are widely approved as safe food ingredients by regulators worldwide, while chemically altered forms (partially hydrogenated) have been restricted or banned due to trans fat content.

Safety summary

The regulatory and scientific consensus.

Unhydrogenated vegetable oils are broadly recognized as safe; however, high-temperature refining generates process contaminants — notably glycidyl fatty acid esters (GE) and 3-MCPD — which EFSA has identified as genotoxic/carcinogenic and of particular concern for infants and high consumers in all age groups. Partially hydrogenated vegetable oils (PHOs), the primary dietary source of artificial trans fats, were determined not GRAS by the FDA in 2015 and banned from US food manufacturing by 2018, with similar trans fat limits enforced globally. Excess consumption of omega-6-rich refined oils has been linked in observational research to pro-inflammatory effects and cardiovascular risk.

Regulatory landscape

What food-safety regulators have decided.

Jurisdiction	Status	Note
FDA (Food and Drug Administration) (United States)	Banned	Applies specifically to Partially Hydrogenated Oils (PHOs), the primary source of artificial trans fat. FDA's final determination released June 16, 2015; manufacturing compliance date June 18, 2018.source
FSANZ (Food Standards Australia New Zealand) (Australia)	Approved	Vegetable oils are permitted food ingredients under the Australia New Zealand Food Standards Code. No established ADI. Trans fat limits apply to products containing hydrogenated vegetable fats.source
EFSA (European Food Safety Authority) (European Union)	Approved	Unhydrogenated vegetable oils are permitted food ingredients in the EU. EFSA has flagged process contaminants — glycidyl fatty acid esters (GE) and 3-MCPD esters — formed during high-temperature refining (approx. 200°C) as potential health concerns, especially for infants and young age groups; EU legislation was being finalized to reduce GE levels. No formal ADI for the oil itself.source
FSSAI (Food Safety and Standards Authority of India) (India)	Approved	Governed under FSS Act 2006 and FSS (Food Products Standards and Food Additives) Regulations 2011, Regulation 2.3.15. Industrial trans fatty acids are restricted to ≤2% by mass of total oils/fats in any product (amendment in force from 2 February 2021, compliance by 1 January 2022). Used cooking oil with Total Polar Compounds (TPC) >25% must not re-enter the food chain. All edible oils except coconut and olive oil must be refined before human consumption sale.

Who should approach with care

Whose guidance would steer them away.

Infants — EFSA found that GE exposure in infants consuming solely refined-oil-based infant formula can be up to ten times what would be considered of low concern for public health, due to glycidyl fatty acid esters formed during high-temperature oil refining.

Children — EFSA identified average GE exposure as a potential health concern for all young age groups, given the genotoxic and carcinogenic nature of glycidyl fatty acid esters present in refined vegetable oils.

Heart Disease — Partially hydrogenated vegetable oils (PHOs) are a primary dietary source of artificial trans fat, and FDA determined their removal from food could prevent thousands of heart attacks and deaths each year; patients with heart disease should also be cautious about high intake of omega-6-rich refined oils.

Pregnancy — Refined vegetable oils contain GE and 3-MCPD process contaminants; EFSA flagged these as potential health concerns for high consumers, warranting care in choosing minimally refined or cold-pressed oils during pregnancy.
