Question
How many calories do you need to replace the tissue lost when you give a pint of blood away?
Answer
We put this to Professor Adrian Newland:
Adrian - About 650 calories, which I'm reliably informed is 3 Mars bars.
Chris - Why would it take energy to replace blood? Adrian - Anything that develops tissue requires energy.
Chris - So what you're saying is you just need to put the energy back in.
