eli5 : how come when you thaw out meat you’re not supposed to re-thaw it?

Question

I’m not sure if this is true or not but it’s something I’ve heard when I was younger so I’ve just always taken it as a rule.
Is there a reason why you’re not supposed to re-freeze meat once it’s been thawed out?

Answer 1

I mean if you’re just thawing it then re-freezing it straight away after, there’s minimal health risk, but the quality decreases because you lose moisture and momentarily increase oxidative changes to the fats and proteins that wouldn’t happen at a lower temperature.
