- [What is an ADI? Understanding the "safe intake" figure for additives](https://logicfood.app/en/blog/what-is-adi-acceptable-daily-intake/) (31 October 2026): The acceptable daily intake (ADI) is a number that appears often in additive news but is often misread. How is it set, what happens if it is exceeded, and why is comparing substances by it misleading?

- [What are BHA and BHT? Understanding E320 and E321 on labels](https://logicfood.app/en/blog/bha-bht-antioxidants/) (31 October 2026): BHA (E320) and BHT (E321) are synthetic antioxidants that delay fats going rancid. The IARC classification and EFSA's intake limits only make sense when read together.
- [What the "activity and attention" warning on food colours means](https://logicfood.app/en/blog/food-colour-attention-warning/) (31 October 2026): Some labels say a colour "may have an adverse effect on activity and attention in children."
