Seaweed's problem may not be the flavour. Among 3,486 Europeans willing to try it, more people marked down the look and the chew, and 57% of Irish people who had never eaten it already held the texture against it

Seaweed keeps getting pitched to European shoppers as a greener food and a possible way to cut salt, yet interest seems to run ahead of appetite. In one Swedish study quoted in this new paper, over 95% of people said they were interested and 41.2% ate it monthly or more often. A team working in Ireland, Norway, Spain and South Africa wanted to know what people have in mind when they think of it. Their results appeared in Food Science & Nutrition on 26 October.

They ran an anonymous online survey through consumer panels and kept only those who answered yes to "Are you willing to try seaweed products?" That left 711 people in Ireland, 763 in Norway, 1,075 in Spain and 937 in Turkey. Each person said whether they had ever eaten seaweed or a seaweed-based food, rated colour, appearance, flavour, taste and mouthfeel as a positive or a negative, and then picked words they connect with seaweed. No seaweed was served at any point.

The sharpest numbers came from Ireland. Among Irish people who had never eaten seaweed, 56.8% counted its mouthfeel as a negative and 54.3% its appearance. Among Irish people who had eaten it, those figures were 35.1% and 28.1%. Reading across the paper's table, we noticed a pattern the authors didn't test directly: in all four countries, in both groups, appearance and mouthfeel each drew more negative votes than flavour. Among those who had never eaten it, 14.9% to 29.7% marked down the flavour, against 27.2% to 54.3% for the look. In every country and on all five counts, people who had eaten seaweed were more positive than those who hadn't.

The words people chose differed by country. Salty led everywhere, at 85.8% to 91.4% in Ireland and roughly 60% to 70% elsewhere. Over half of Turkish respondents called seaweed herbal, and 58.6% of those who had never eaten it called it sour, though the authors warn that taste words may not travel cleanly between languages. Among people who had eaten seaweed, 79.5% in Spain picked marine as a flavour, against 37.4% in Norway. Metallic, chewy and sticky tended to go with a poor opinion, and creamy with a good one in all four countries. Seafood-like split opinion: it counted in seaweed's favour in Ireland and Spain, but it was divisive in Norway and Turkey.

The limits matter here. Anyone unwilling to try seaweed was removed, so these figures flatter it, and this paper says nothing about how reluctant the wider public is. The survey also takes a single snapshot, so people who had eaten seaweed may simply be those who were well disposed to begin with. Some who said they had never eaten it may have had seaweed-derived thickeners without knowing, and the survey didn't ask which species people had in mind. Nothing here concerns health. The authors' own suggestions are aimed at food makers, such as finer particles, flavour masking or changing the texture, and they say those ideas still need testing with real prototypes. For now this is a map of expectations, not a verdict on any food.
