New warning for anyone using almond, soy or oat milk, cheese and yoghurt

Summary

A study in The Lancet Planetary Health suggests that replacing dairy with plant-based alternatives could lead to micronutrient shortfalls, especially in iodine and calcium among women and teenagers. Outside experts and advocacy representatives note that fortification and varied diets can mitigate these concerns.

Key Takeaways

1. Replacing dairy products with plant-based ones, such as oat and almond milks, could lead to people missing out on vitamins and minerals, a study suggests.
2. The team, from the University of Surrey and Queen’s University Belfast, found that even modest replacements of dairy intake with plant-based dairy alternatives (including fortified ones) led to declines in all four micronutrients, but particularly iodine.
3. Tom Sanders, Professor emeritus of nutrition and dietetics at King’s College London, said a weakness in the study was that “iodine deficiency cannot be reliably predicted from dietary intake records because the iodine content is dependent on the amount in the soil in which plant foods are grown”.

Credibility & Bias Reasoning

Credibility assessment: The reporting relies directly on a published study from The Lancet Planetary Health along with survey data from the National Diet and Nutrition Survey. It quotes the study's lead authors as well as several independent academic researchers. Countering viewpoints from The Vegan Society and PETA are also represented.

Bias assessment: Slight Alarmist Framing. The headline uses urgent warning language for a nutritional modeling study. However, the body text remains fairly balanced by presenting the methodology, quoting study researchers, and providing critical responses from outside experts and vegan advocacy groups.

Note: Reports on academic dietary modeling with reactions from outside experts and advocacy groups.
