Extreme weather events are increasingly influencing how people shop for food, with the UK government encouraging households to build emergency food supplies that include long-lasting products. Environment Secretary Dame Angela Eagle has warned that the El Niño climate phenomenon—characterized by unusual warming of ocean surface temperatures in the Pacific—could lead to more frequent and severe storms in the UK. She also highlighted that factors such as climate change, cyber-attacks, disease outbreaks, and global conflicts could disrupt the food supply chain, making it important for individuals to be prepared for potential shortages. Prof Richard Wilding, an expert in supply chain strategy, suggests that while there is no need to panic, it is wise to be aware that items commonly found in supermarkets might suddenly become scarce. He emphasizes the importance of planning ahead to ensure food availability during unexpected disruptions. Nutrition experts have provided guidance on which foods to prioritize for emergency supplies. Dr Sammie Gill from the British Nutrition Foundation recommends focusing on complex carbohydrates such as wholegrain cereals, oats, and pasta, along with proteins like canned legumes and oily fish. Consultant dietitian Rebecca McManamon adds that tinned fruits are a good source of fluids, vitamins, and fiber, while pickled vegetables and eggs are also essential. Both experts suggest keeping non-refrigerated long-life milk for its nutritional value, including protein and calcium. When selecting tinned foods, Dr Gill advises against products preserved in brine or syrup, as water is the healthiest option. She also warns against instant noodles, tinned soups, and processed snacks high in salt and sugar. Tinned fish is a better choice than processed meats, which tend to be high in salt and saturated fat. Both experts caution against over-consuming sweets like biscuits and chocolates due to their high sugar content. For flavor, McManamon recommends having dried herbs, spices, and salt on hand. She also suggests aiming for 1,500-2,500ml of fluid daily, which can be achieved through bottled water or fluid-rich tinned foods if necessary. While the canning process may reduce some vitamins, tinned foods can still be a valuable source of essential nutrients.
