Demand for fish in Great Britain is driven by household income and taste.
Article in Public health nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveFish is high in nutrients that provide a range of health benefits, but people in Great Britain only consume around half the amount that is recommended. This study analysed the demand for fish for consumption at home across different household groups in Great Britain.
designUsing a Rotterdam demand model, price and income elasticities were estimated for eleven fish groups across seven household groups. To investigate changes in fish demand, we decomposed growth in fish demand into income, relative price and change in taste and seasonality.
settingThe data used for our analysis were drawn from the Kantar Worldpanel dataset for Great Britain for the period from 2013 to 2021.
participants12 492 households in Great Britain.
resultsFamilies with children consistently allocated a lower share of their grocery spending on fish and preferred to purchase ready-to-use and convenient fish products, compared with households without children. Purchases of chilled fresh/smoked oily fish, canned oily fish and frozen processed fish led spending across demographic groups, whilst purchases of canned oily fish showed minimal growth. The demand for most fish products across household groups was price inelastic, indicating that the percentage change in the quantity of fish demanded increased or fell by less than the percentage change in price.
conclusionsIncome and taste were identified as significant determinants of demand changes across all household groups, while price only played a prominent role in demand changes for certain fish groups. Thus, increasing fish consumption, especially in lower-income groups, who do not usually consume much fish, may require a different intervention than simply making fish more affordable.
