Pitahaya is sold with the indication «Price per unit». The price therefore refers to one piece. No fixed net weight per unit or total gram amount is declared for the item offered. The description highlights its high fiber and water content and presents it as a low-calorie food. It states that it does not exceed 100 kcal per 100 grams of edible portion and that it is a source of carbohydrates, with a very moderate energy contribution. The reference to 100 grams corresponds to the nutritional information for the edible portion, not to the weight of the commercial unit. In addition, the energy figure is given as an upper limit, not as an exact value. The available information does not specify the country or region of origin, the variety, or the type of packaging. It also does not include storage conditions, preparation instructions, or a full nutritional breakdown.
