When you’re keeping an eye on everyday spending, you don’t want to needlessly throw food away too soon. But at the same time, you don’t want to risk eating something that might have gone off.
One of the main problems is, we’ve become so reliant on ‘Best Before’ and ‘Use By’ dates on packaging, that we’re less confident about relying on our own judgement on whether food is fresh or not. Older people’s immune systems also tend to be less able to recover from food poisoning. This makes knowing how to store food safely and for longer vital to avoid becoming ill.
