Porthmadog council has also expressed opposition to the plans, labelling them as “over-development” and raising concerns about traffic, parking, and the fact that a chip shop already exists nearby, according to the BBC.
They argued that the new takeaway could exacerbate these issues.
Betsi Cadwaladr health board has been contacted for comment by The Telegraph.
It has yet to confirm whether the fish and chip shop will adapt its menu to include more fruit and veg options.
The Welsh government has introduced other measures to steer people towards healthier diets.
‘Healthy choices’
In July, Welsh authorities announced that free refills of sugary drinks could be banned in cafes and restaurants as part of a push to encourage “healthy choices”.
Eluned Morgan, Wales’s health minister, launched a consultation on a number of measures which the Labour-run government wants to see made law at the end of next year.
The regulations would apply to foods and drinks high in fat, salt or sugar, and affect popular fizzy drink promotions at restaurant chains including Nando’s and Five Guys.
Buy-one-get-one-free offers on certain products would also be banned under the proposals.
Supermarkets would be prohibited from placing high-fat products in certain locations, including shop entrances and checkouts, as well as advertising them on website homepages.
