According to the World Health Organization, adults should not consume more than 5 g of salt per day, while children are advised to consume only 2 g spread across their meals. However, the prevalence of prepared foods that greatly exceed these limits and a strong addiction to this flavor enhancer among consumers pose a public health challenge. WHO member states have agreed to reduce salt consumption by 30% by 2025, particularly by negotiating with manufacturers. A mere 15% reduction could potentially prevent 8.5 million premature deaths over ten years in low and middle-income countries.
Japanese company Kirin has innovated the Electric Salt Spoon to address high salt intake, inspired by data showing that Japanese citizens consume an average of 10.1 g of salt daily. This spoon employs electric power to enhance the salty flavor of low-sodium foods. A small electric current stimulates taste buds, increasing sodium perception and creating the illusion of a saltier dish.
The device could aid those on low-sodium diets, such as individuals with hypertension or heart failure. Kirin's spoon may also appeal to consumers who typically use too much sodium. It enhances umami sensation linked to glutamate and nucleotides found in foods like tomatoes, fish, and green tea. Currently priced at 19,800 yen (approximately $125) in Japan, the spoon features adjustable electric intensity and is not suitable for minors or those with medical devices. Kirin plans to launch this product globally soon.
