But the fruit could soon become even more popular after a Spanish company announced it was launching reduced-fat avocados for the first time.
Isla Bonita claims their Avocado Light has up to 30 percent less fat than ordinary fruits.
It said it also ripens faster, and oxidises - or goes brown - slower.
The avocados are grown under special soil and climate conditions to provide the same nutritional benefits with less fat, according to the company's website.
Avocados' rich, creamy texture is caused by their high fat content - an average fruit has between 20-30g of fat.
Most of this is monosaturated fat, which has been linked to the reduction of cholesterol and lowered risk of cancer and heart disease.
However, a morning avocado on toast could be less virtuous than you think, with the UK's National Health Service recommending only one half as a portion size.
A large avocado contains about 330 calories, just under one fifth of the daily recommended intake for an average woman.
The lower-fat version is set to be launched in Spain this month at a trade fair in Madrid.
A representative for the company behind it told industry magazine Fruitnet the light version could mark the "second big jump in the development of the avocado market".
It was unclear if the fruit tasted any different but its makers said it has a "soft and pleasant pulp".
