What level of verification currently limits the therapeutic application of purple corn for human kidney health?
Answer
Preclinical level
While preclinical research, primarily involving controlled animal models such as rats, shows strong and consistent evidence that anthocyanins from purple corn can protect against the damaging effects of diabetic nephropathy, a significant barrier remains. This compelling evidence has not yet been fully translated or verified through high-quality, randomized controlled trials involving human subjects who have diabetes and existing kidney concerns. Therefore, the scientific consensus confirms its potential at the preclinical level, but this potential has not been clinically established or proven for practical human therapeutic application.
