A computerized food and beverages ordering apparatus implements an ordering service for meeting requirements of purchasers. A database comprises records representative of a plurality of ingredients, and at least two attributes are associated with each ingredient. One of the attributes associated to each ingredient is a nutritional parameter for a specific amount of the ingredient, and another attribute is a personal parameter. The personal parameter can be a parameter capable of describing the suitability of the associated ingredient in respect of a medical condition of a purchaser, or it can be a parameter capable of describing the suitability of the associated ingredient in respect of a taste requirement of a purchaser. A user interface is operated by, or under the instruction of, a purchaser to input an order for a meal. The meal comprises one or more of said plurality of ingredients, and each ingredient has an associated quantity. An order placement processor is connected to the user interface and to the database, and it is configured to output to the user interface at least two output parameters. One of the output parameters is a total nutritional parameter computed from the total quantities of ingredients comprised in the meal. Another output parameter is a personal parameter.
