Avoid industrial trans fat
Removing industrial trans fat reduces an avoidable dietary risk to heart health.
The number, drawn
More than 278,000 deaths a year are attributed to industrial trans fat
Why it matters
Trans fat worsens blood cholesterol and contributes to coronary heart disease. WHO attributes more than 278,000 deaths a year globally to industrially produced trans fat and recommends keeping total trans fat intake below 1% of dietary energy. The practical benefit is greatest where these fats are still sold, since many countries now limit them by law.
How to do it
- Check ingredient lists for partially hydrogenated oils where labels are available.
- Choose products made with nonhydrogenated oils.
- For unpackaged fried or baked foods, ask which fat is used or choose an alternative.
Do it
Pick the time you have. Anything beats nothing.
Start with the time you have
5 minutes
Check one packaged baked food's ingredients for partially hydrogenated oil; if listed, compare an alternative without it.
15 minutes
Check three foods you buy often for partially hydrogenated oil and note replacements; labels and availability vary by country.
A plan
Check your regular purchases
- Stage 1: Check the ingredient lists of your usual spreads and baked snacks.
- Stage 2: Replace products listing partially hydrogenated oil with suitable alternatives.
- Stage 3: Ask about the cooking fat when buying unpackaged foods where these oils may still be used.
In real life
- Where partially hydrogenated oils are sold, choose a similar product without them.
- Ask a bakery which fat it uses when ingredients are not displayed.
- Use olive or rapeseed oil instead of shortening made with partially hydrogenated oil.
Watch out for
- Common mistakeDo not confuse fully with partially hydrogenated oil: check the exact wording and saturated fat content.
- Common mistakeDo not assume all margarine contains industrial trans fat: check the ingredients for the product you buy.
