Patsy Kensit talked on Woman's Hour last week about her father calling her eagerly to Sunday lunch.
"Come in for the bird. Come in for the piece of meat." As a child, his excitement at the prospect bewildered her. What was the big deal, she and her brother wondered.
The big deal was that her father had "literally starved for weeks on end" during his childhood in Bethnal Green. To have meat was therefore important.
People who know hunger never forget it. I interviewed Robert Maxwell once. He was fat man holding court in his penthouse suite atop the headquarters of his media empire but he told me his abiding memory of childhood was living on a dirt floor and being hungry. It hurt him still.
My own mother wouldn't ever allow me and my sisters an orange in a packed school lunch. She said other children might be hungry. The smell of the orange would make it worse. We thought she was dotty but she'd been a war child. She'd seen children destitute and half-starving.
You can see something of the same today too if you know where to look. Two hundred thousand Scottish children live in relative poverty. Too many of them also know hunger. The number of Scots relying on food banks has multiplied six fold to around 23,000, six times the number for the same period last year.
I imagine it is a matter of shame and humiliation for those unable to make ends meet or to feed themselves. But is that where the shame should lie?
Zoom out from people now reduced to living off food donations and have a look at what surrounds them. Thanks to Tesco we now have a wider picture. We can now see where the real disgrace lies.
This one supermarket chain wasted 28,500 tonnes of food in the first six months of this year. We are guilty too. Together Tesco and its customers binned 68% of bagged salads along with 40% of apples, 25% of grapes and 20% of bananas.
Even more shockingly, nearly half of Tesco's bakery produce was thrown away.
It would be shameful if no one was hungry. With need as great as it is, this waste is borderline criminal. Remember, this is just one supermarket chain. The total UK annual waste is 15 million tonnes of food.
The average family wastes £680 a year just by throwing away food. Set that against the recent hue and cry over rising energy prices.
Tesco has done us a favour by holding a mirror to our profligacy. By aggregating the waste and presenting us with a grand total, it is confronting us while admitting its own culpability.
The solution? It is staring us in the face. If we eliminate food waste, we can give the saving to those most in need or we can afford to heat our homes this winter - or a bit of both.
Suggestions from Westminster that we put on an extra jumper are patronising (as if we hadn't worked out for ourselves that an extra layer helps in cold weather). But there is a truth in the message. We all feel impotent in the face of rising fuel prices. Food costs are going up just as much but we remain quick to consume and slow to change our lifestyles.
For those generations that grew up without central heating, it's not such a leap to live with a slight chill in the air. But even they know that once the temperature drops to freezing, jumpers aren't enough. Heating is essential in a cold climate like ours but perhaps we can help ourselves by heating only the rooms we are using.
Many more of us would also better control our food consumption by growing our own, if only we could access land. Across Scotland thousands of people are queuing for an allotment in the hope of doing just that. But waiting lists stretch to 10 years in some places - even though 31% of us live within half a mile of a derelict site.
Councils are legally obliged to provide allotments. Unfortunately they can't be held to a time scale. I hope Scottish Green Party MSP Alison Johnstone succeeds in her call for a "right to grow". It would be timely to see Scotland's 27,000 acres of derelict or vacant land used to help the community to feed itself cheaply and well.
I have seen the transformation of just such a reclaimed plot in my local neighbourhood. For decades this triangle of ground has been an eyesore. Now it contains a clutch of beautifully maintained allotments and a small community building which offers shelter in the winter and a gathering place year round. On summer evenings it's a pleasure to see families working together and socialising. It is giving the entire area a lift.
This sort of activity offers an added value that is hard to put into words. But just walking past it is obvious that the home grown cabbages and tomatoes (and the money saved) are only some of the benefits the gardeners and their children derive from the experience.
We had an allotment when our children were small. They loved the freedom, the ability to dig and plant and splash in the water butt. They also loved the elderly couple who worked the plot next to us, who spoiled them. They had fresh air, entertainment and companionability. They were learning new skills and they were happy doing it. It was, if you like, a taste of The Good Life.
You don't waste what you grow. You also don't waste what you cook. Make a loaf and you'll find yourself Googling bread and butter pudding recipes to use up the stale bits. Cooking is cheaper than buying ready meals and allows the figure conscious to control sugar content and portion size. It's also creative and gratifying and tastes good.
Ceasing to throw money we no longer have at food we don't even eat has to be a better way forward. Over consumption is gross. Buying food and binning it a few days later is disgraceful. At a time when people are suffering real hardship and deprivation, it is shameful.
Tesco is trying to make amends by stopping its "buy one get one free" offer on large bags of salad. It is reducing the amount of bread it has on display and sourcing longer life grapes. Friends of the Earth say it needs to go much further; to reduce its ordering and stop demanding "cosmetic perfection" in fruit and vegetables.
I remain grateful that Tesco has flagged up the issue. It will allow us to correct our own profligacy by perhaps enjoying a simpler and better way of living. It has even demonstrated that if we eliminate food waste we can make a difference to the cost of living crisis that we are all experiencing. In Tesco's words: Every Little Helps.
