Classic British seaside treats, often steeped in nostalgia, are facing scrutiny from nutrition experts regarding their health impacts. While many popular items like '99' ice creams, candy floss, and deep-fried donuts are high in sugar and processed ingredients, some traditional options, such as cockles, whelks, and oysters, offer significant nutritional value.
Nutritionist Sarah Otto explains that a '99' ice cream, while a nostalgic favorite, contains substantial sugar and often includes emulsifiers and stabilizers that can disrupt gut health. She advises that fruit-based sorbets or coconut milk ice creams are healthier alternatives for a frozen treat. Similarly, candy floss is described as pure sugar with no nutritional value, and its artificial colors require the body to process and eliminate them.
Deep-fried ring donuts are also flagged as concerning due to refined flour, sugar, and repeatedly heated oil, which can lead to inflammation. Slush Puppies are identified as a cocktail of sugar, artificial colors, and flavors, with liquid sugar causing rapid blood sugar spikes. Traditional fudge, composed of sugar, butter, and condensed milk, is calorie-dense and high in sugar and dairy fat.
Fish and chips present a mixed nutritional profile. Certified integrative nutritionist Coco Pierrel notes that the fish itself, such as cod and haddock, is a good source of lean protein, vitamin B12, iodine, and selenium, which support thyroid and metabolism. However, the batter and chips contribute refined carbohydrates that cause blood sugar spikes. Pierrel suggests eating the fish inside the batter and using malt vinegar, as its acidity can slow sugar absorption.
A Cornish pasty, traditionally made with beef, potato, turnip, and onion, is described as a hearty meal. Pierrel points out that while the beef provides protein and vegetables offer fiber, the pastry is high in calories and saturated fat. She recommends enjoying it as an occasional treat rather than alongside other dishes.
Pint of prawns are highlighted as a classic seaside snack that is low in fat and rich in iodine, selenium, and astaxanthin. The nutritional impact largely depends on the accompanying sauce, with mayonnaise or Marie Rose sauces being high in calories. A squeeze of lemon is suggested as a healthier accompaniment.
In contrast, some less conventional seaside snacks are praised for their health benefits. Cockles are considered an underrated food, being low in fat, high in protein, and a significant source of iron and vitamin B12. Whelks are also noted as a lean, protein-rich option packed with iron, magnesium, and selenium without the saturated fat found in processed meats.
Oysters have earned their reputation as a healthy choice, being one of the richest natural sources of zinc, essential for the immune system, along with vitamin B12, iron, and omega-3s. Experts advise pairing them with lemon or a light mignonette dressing, while cautioning against sugary cocktail sauces.
