Many Box turtles (and other omnivorous turtles) are often mistakenly fed a diet based primarily on fresh vegetables and fruits, sometimes only augmented with small amounts of essential animal/insect proteins. Most fresh fruits and vegetables contain upwards of 80-90% water. WATER! In most cases, only 6-8% of this “fresh” food source actually contains any nutrient content whatsoever. Most of it, unfortunately, is just plain water and a great deal of non-digestible plant fiber (cellulose) with little or no nutrient content. It is because of this that turtles being fed on this type of diet must consume huge amounts of fresh grocery store produce to satisfy their nutrient needs once the excessive volume of water has been expelled. This is why Box turtles eat so much “fresh” food. In contrast to this, when box turtles (like any turtle) are fed a diet with a much more concentrated nutrient content, like TropicZone Performance Box Turtle Diets, it needs to consume far less quantity to satisfy its nutrient requirements and calorie intake. This is why it may “appear” that the turtles are not eating “enough” of the TropicZone Performance Box Turtle Diet (compared to fresh foods filled with water), when in fact, they are consuming all they need to stay healthy and well nourished!
