Prof Chris Elliott said a lack of essential micronutrients could have severe consequences and lead to "hidden hunger" in the developed world.

Poor bone health, lower omega-3 and iodine levels and a vitamin B12 deficiency are among those cited.

Hidden hunger occurs when the quality of food people eat does not meet their nutrient requirements.

But a dietician from The Vegan Society has refuted these claims.

"Well-planned vegan diets contain all the nutrients that our bodies need," Heather Russell told BBC News NI.

• Veganism: Why is it on the up?
• Why I gave up being vegan
• Going vegan: Is it just a fad?

There are four times as many vegans in the UK as there were four years ago - they do not eat meat, poultry, fish, or any products derived from animals, including eggs, dairy products, and gelatin.

In an article published on academic website The Conversation last month, Prof Elliott and QUB lecturers Claire McEvoy and Chen Situ suggest vegans can prevent micronutrient deficiency by consuming foods fortified with vitamins and minerals, as well as taking supplements.

"We work with the British Dietetic Association to share the message that they can support healthy living in people of all ages," said Ms Russell.

"If you're switching to a totally plant-based diet, set aside a bit of time to work out how you're going to hit your nutrition targets without animal products."
