We got tomatoes in our veg box this week.
They were grown at a local farm. Great for keeping down food miles.
But it’s November.
So how did they get us fresh tomatoes?
They either picked them green and left them to ripen for a month or grew them in heated greenhouses.
Neither option is ideal. If they were picked weeks ago, their nutritional content and flavour will have been declining from the moment of picking.
If they were grown in greenhouses, then there’s the environmental impact of heating and irrigation to consider. It costs a fortune to protect delicate crops from November frosts.
The in-box leaflet said “vine ripened”, so I guess these are greenhouse tomatoes.
But why should we care?
Basically, if you’re looking at the impact of your food, it’s not enough just to consider food miles. You should also look at how it was grown.
Produce grown in the UK out of season may be more environmentally damaging than importing it from abroad. It doesn’t take many weeks of greenhouse heaters and irrigation systems to negate the damage caused by a lorry. Local, in this case, might not be the best option.
But you can’t easily tell how your food was grown. So what can you do?
Bite the bullet and go seasonal. If it’s in season and local, then you know you’re doing your best to “eat green”.
It can be tough to make the change. After all, fresh tomatoes in winter are a luxury. It just takes practice and planning. The best way to start is by knowing what’s in season when and how to cook it. Then you quickly get to the stage where you look forward to seasonal variations.
And if your veg box is bringing you stuff that concerns you, tell your box scheme provider. They’re under pressure to keep up the variety and stop you getting bored. But if you notice too many unseasonal goodies creeping in, have a word with them!

You may find this study interesting, it finds that the energy used in producing and shipping dairy products (butter/cheese) from New Zealand to the UK is half that from producing it in the UK, for lamb it is a quarter (grass grows with little fertiliser, compared to using feedstock), and 40% less for apples.
