Contrary to what many might think, fresh spinach isn't always superior; nutrients can diminish during transport and storage, as found by research from Pennsylvania State University. Another study revealed that spinach could lose up to 75% of its vitamin C within a week, hence the practice of freezing it soon after harvest to retain its nutritional value.

Tim Spector, professor of genetic epidemiology at King's College London and co-founder of the health app Zoe, has even cautioned his followers against being "snobs" about frozen food.

He mentioned: "Like me, You probably always thought that fresh food is always the best option. Don't be a snob when it comes to frozen foods or canned foods that can often be lifesavers."

In particular, Dover Sole is touted by the Nutrition And You website as one of the most calorie-efficient flatfish available and heralded as an "excellent" source of essential fatty acids. Research from Cornell University and the New York Sea Grant Extension Program has underscored the vital role of essential fatty acids in maintaining cardiovascular health.
