Studies from prestigious universities including Pennsylvania State, Ohio and Tufts have linked eating avocado to health outcomes like better cognitive function, improved blood pressure, lower blood sugar, better diet adherence and improved cardiovascular health.

Five years ago, oversupply saw growers burying the fruit they could not sell, but chief executive of grower-owned marketing group The Avolution, Antony Allen, says the research is playing a role in improving demand.

He says the studies were done independently from the industry, giving the results more credibility.

"What we're talking about is world class university research centres working on this sort of work, it's not just some backyard operation, we're talking about some of the most elite universities in the US," Mr Allen said.

"They're blind trials and they actually did trial that - people were actually eating exactly the same other fruits and vegetables and the only change that they used was the addition of the avocado.

"So there's obviously something in that avocados have just got that little extra push."

He said the findings could help the fruit shake off its long association with health negatives like cholesterol and bad fats.

"It was only research that proved that that was not the case, it was actually the opposite to what had been developed up and that's a very good example from a very complicated research situation to what is just a very simple message - avocados have good fats not bad fats," he said.

"It means that we've got another aspect of avocados which is strengthened by science.

"I don't think it will revolutionise how avocados are marketed but it just adds to that push, that position, and probably most essentially it reinforces that avocados are not a food fad."

He said the new information added to the value of the product, giving growers an opportunity to make the most of the market.

Growers know what's good for them

Lachlan Donovan has been growing avocados in Bundaberg, Queensland, for about 25 years, and said the findings back up what growers have known for decades.

"Being in the industry we've known that for a long time so it's really reiterating the fact of how healthy they are," he said.

"Years ago it was the Guinness Book of Records that said the avocados were the healthiest fruit in the world, but there's a lot of research that's coming through from the (United) States and all over the place that's proving the fact."

He said consumers were taking more notice of the healthy aspects of food, and that was translating into demand, with average consumption in Australia sitting at about 3.2kg per person per year.

"When we came into it is was around about 1kg per person, so over that last 20 odd years it's certainly gone up a huge percentage," he said.

"It's become a more staple dietary item that people will purchase a lot more regularly than what they did in the past as part of the shopping list.

"Previously it was more an exotic fruit and the health benefits is a big part of that where it's good for the heart, it's good for the eyes, so many different things that it is a superfood."
