Hidden Names for Fats, Decoded.
Fats hide behind dozens of names on food labels — saturated, mono- and polyunsaturated, trans fats, tropical oils, palm-derived ingredients, and modified fats used as emulsifiers. All contribute to your daily fat intake. Some carry additional regulatory notes. This reference decodes every name, by type. Free. Open. No paywall.
UK adult guidance (NHS): no more than 30g of saturated fat per day for men, 20g for women. UK average intake sits around 12.5% of daily energy from saturated fat — above the <11% guideline. Industrially produced trans fats are limited by retained EU law to 2g per 100g of total fat in food. Most hidden fat in the UK diet comes from processed and ultra-processed food, where it appears under technical names. Knowing what to look for on a label is the first step.

Why this matters. Nutrition labels show fat and saturated fat per 100g, but ingredients lists use specific names — "palm oil", "interesterified vegetable fat", "mono- and diglycerides of fatty acids", "fully hydrogenated rapeseed oil". This reference explains what each name actually is and where the regulatory or dietary thresholds sit.
How fat thresholds work. Per FSA front-of-pack rules: high fat is more than 17.5g per 100g; high saturates is more than 5g per 100g; low fat is 3g or less per 100g; low saturates is 1.5g or less per 100g. Per portion thresholds also apply for products consumed in single servings.
Trans fats in UK food. Retained EU Commission Regulation 2019/649 limits industrially produced trans fatty acids to 2g per 100g of fat in food sold to the final consumer. The limit applies to industrial trans fats only; naturally occurring ruminant trans fats (from beef, lamb, dairy) are not restricted.

Verdicts. Worth flagging — carries a regulatory limit, restriction, or material context most readers benefit from knowing. Worth knowing — context-specific note (sustainability, cardiovascular guidance, dietary pattern). It's still fat — standard dietary fat that contributes to your daily fat total.
What this is not. Not medical advice. Some fat is essential. The body needs essential fatty acids (omega-3 ALA, omega-6 LA) which it cannot make. For tailored dietary advice on fat intake consult a GP or registered dietitian.
Why this is free. Per SCANSMART's Belongs-to-Everyone Rule.
