One woman is taking up a challenge for the month of September: to eat only Irish produce.
This means only eating things that are grown and produced here.
Lisa Fingleton is an artist and farmer from Co Laois, who is now based in Kerry.
She told Moncrieff this is the best time of the year to do it.
"September is a really good month for Irish farms and Irish growers.
"We have apples and honey from the hives, lots of vegetables growing - courgettes, cucumbers, sometimes people have raspberries - there's quite a lot in the garden at this time of the year".
But she said ambiguous labelling has actually made it harder.
"I started the 30-day food challenge six years ago, and I think the labelling has got a bit tricker for people.
"It says 'Produced in Ireland', but it's rice or orange juice, or things that just don't grow in Ireland.
"The labelling is a problem because things marked 'Produced in Ireland' don't necessarily mean that they're actually grown here or that they're from farms here.
"It just means that they were processed here, and that some of the profit was added here.
"The challenge really is a challenge", she said.
'We have amazing soil'
Lisa said Irish people need to stop complaining about the rain.
"We have the most fantastic climate in the world, and we're always giving out about the rain.
"But I think in terms of climate change, when you look [at] what's happening over in Europe or even in China at the minute, people are crying out for rain.
"I know we complain about it - but we need that to grow food, and we have amazing soil here in Ireland and a really moderate climate".
And she said she hopes this challenge makes people realise they can make a difference.
"It actually makes people ask questions.
"If you look at the Siúcra bags - that says Siúcra in Irish on the packet - they're actually produced by a multinational.
"More and more these food products - like HB Ice-Cream is Unilever now - and there's a tiny group of multinationals that actually control pretty much all the food in the world.
"And what we can do as consumers is rather than getting overwhelmed by all this... [is] by actually taking back the power.
"There's a great quote that says 'Every euro you spend tells the world how you want it to be'.
"Whether you've got €1 or €20: if you go out and you hand that money to a farmer in a farmer's market, you are instantly changing the lives of those rural communities and farmers.
"And you're making a difference, I really believe that".
