Nutritional scanners are handheld devices that analyze food items to provide information about their nutritional content. They use various technologies, such as near-infrared spectroscopy, to measure the composition of the food, including calories, fats, proteins, and vitamins. This information helps individuals make informed dietary choices. These scanners are often used by health-conscious consumers, dietitians, and researchers. They can scan a wide range of foods, from fruits and vegetables to packaged products. By offering quick and accurate nutritional data, nutritional scanners aim to promote healthier eating habits and improve overall wellness.
