Centra has recorded sales of €1.54bn in 2015 and revealed expansion plans leading to 16 new stores this year.
The convenience store retailer said the new shops will result in 480 jobs being added to the Centra network, as part of a €16m investment.
Centra’s Live Well products launched in July added €6m in sales of products such as salad boxes, fruit pots and avocados.
Centra also sold 1.5 million more bottles of healthy drinks such as water, coconut water and aloe juice last year.
Martin Kelleher, Managing Director of Centra, said: "We are delighted to announce that our sales figures show a 1.6% growth on the previous year.
"We are delighted with the response that we have had so far, with massive spikes in demand for nutritious products. For example we have sold almost 200,000 salad boxes, 1.4 tonnes of quinoa and an additional half a million pieces of fruit.
We’ve extended our range to include products that you wouldn’t expect to get in a convenience store, such as chia seeds, nut butters and sweet potatoes."
With over 460 stores, Centra employs almost 11,000 people and serves over three million customers per week.
