Phosphoric Acid Concerns
Colas contain phosphoric acid, which some researchers suspect interferes with calcium absorption. Both regular and diet colas demonstrate similar effects on bone health. This similarity suggests the issue extends beyond sugar content. Some researchers suggest the phosphorus content may negatively impact calcium metabolism. “However, this has not been shown in any experimental studies,” one source clarifies. “Along with calcium, phosphorus is a key component of bone mineral, and there is no evidence that phosphorus intake is bad for bone health or raises osteoporosis risk in healthy people.”
