More vegan food should be on offer in Welsh schools and hospitals, according to a group which promotes veganism.
The Vegan Society wants the Welsh Government to increase vegan food choice in all public sector canteens to accommodate the growing numbers who are switching to a plant-based diet.
It plans to launch a petition in the summer.
The charity estimates there are about 500,000 vegans in the UK and says figures are rising.
Dominika Piasecka, a spokeswoman for the Vegan Society, said: "By public sector canteens we mean places like hospitals, schools, prisons, universities, workplaces etc. Basically anywhere where you go not out of choice but because you have to eat.
"If there is no vegan option in places like that, it's a problem as there isn't always a good alternative."
The success of campaigns like Veganuary, where participants sign up to go Vegan for January, has boosted awareness of a vegan diet.
This year 168,500 people across the UK took part - three times as many as in 2017. Cardiff made it into the top 20 of UK cities, in 11th place, with 860 people signing up.
Charlotte Berry puts the trend down to it being easier than ever to avoid meat and dairy. She opened a Vegan shop in Swansea Market in January 2017 and said the number of food suppliers she can choose from has trebled in the last year. Business is doing so well she is looking to expand into a bigger unit.
"Convenience products have seen the biggest rise," she said. "It used to be snacks were hard to find as a vegan, but now there's so much choice and I think that's driving the trend towards more people switching. All the supermarkets are offering more vegan products and social media has made it easier than ever to give people ideas for recipes and nutrition advice."
Verdi's Ice cream parlour in Swansea is one of many restaurants to respond to the growing food trend. They launched a vegan ice cream last month.
"We tried making vegan ice cream 24 years ago," says Matteo Moruzzi, who uses soya milk instead of cream.
"No-one was interested then, but the market has definitely changed. This time we had hundreds of shares on Facebook and loads of people were coming in wanting to try it."
'Easy to be healthy'
In 2017 the Office for National Statistics reported that for the first time non-dairy milk had made it into the consumer price inflation basket, which reflects buying habits.
Health benefits, climate change and animal welfare are all factors behind people making the shift, and it's spawning a growing number of business opportunities.
Ky Wright from Tenby has just raised £80,000 on the crowd funding site Kickstarter to produce an organic food supplement bar called "Human Food".
It is aimed at those on a plant-based diet who want to ensure they get all the nutrients they need.
"The response has been amazing," he said.
"Lots of people have told us that they want this product because it makes it easy to be healthy and vegan.
"First of all 20 people were signing up, then 30, and even though we did not have any advertising budget it just kept building and growing."
