When the Australian magpie, an omnivorous bird, is exclusively fed beef mince from skeletal muscle, eventually those birds suffer bone fractures due to nutritional deficiency from a nutrient imbalance.
When fast growing mammals like weaned puppies or kittens are fed all meat diets they also get pathological fractures of their growing bones.
The underlying mechanism is an imbalance in the calcium to phosphorus ratio in the diet. Muscle meat being higher in phosphorus and lower in calcium.
At risk of scaring comments away, the disease is known as nutritionally induced secondary hyperparathyroidism.
Can this high phosphorus to calcium ratio eventually be a problem for an adult human? By resulting in calcium draw down from bone storage thinning the bones as the body’s homeostasis tries to balance the higher phosphorus intake and preserve calcium for all its important physiological functions?
