How to Check for Trans Fat
The most useful step is to check the ingredients list, not just the front-of-pack claim.
Look for:
- Partially hydrogenated oil
- Partially hydrogenated vegetable oil
- Hydrogenated vegetable fat
Also note that a product labelled “0 g trans fat” may still contain a small amount per serving, depending on local food-labelling rules.
Bottom Line
The biggest concern is usually industrially produced trans fat, particularly from products containing partially hydrogenated oils. Many foods on this list may now contain little or no industrial trans fat because regulations and reformulation have changed food products. The exact product label is the best way to check.
