Whether a visionary strategy or a happy accident that people are more health and food conscious than ever before, Glanbia is reaping the benefits of a turn in consumer trends in the past decade.
Chief executive Siobhán Talbot attributed the 13% surge in the firm's stock market value to the new global eating patterns.
Stock markets were certainly impressed by the evidence her strategy was working: The shares surge added about €700m to bring its value to over €5.4bn.
"I think the evolution of Glanbia is that now we have a strategy clearly focused on the global consumer that is looking for nutritious products, that supports health and wellness.
People want to buy in convenient formats and channels - our strategy plays into that.
"We had a very good response to our capital markets day in the middle of last year, and I think it (market reaction) is a build on that.
Brands such as Optimum Nutrition, BSN and Isopure, traditionally the realm of the bodybuilder or fitness fanatic for their high protein focus, are now mainstream by expanding into chocolate bars, biscuits and milkshakes.
"We now have a suite of nine brands. We’ve become even clearer ourselves strategically on where those brands will play.
"While there are specific brands that will play well in certain parts, the beauty of Optimum Nutrition is that it can stand that full spectrum, which is a great place to be," Ms Talbot said.
Sales in its performance nutrition division grew 2%, while its €308m purchase of SlimFast in the US appears to be paying off.
