To mark World Avocado Day on 31st July, the World Avocado Organisation is highlighting emerging research and lesser-known facts about one of the world’s most popular fruits. While avocados are best known for dishes such as avocado toast and guacamole, a growing body of research suggests they may support health in several ways, including maternal nutrition, sleep quality, eye health, and overall nutrient intake.
Pregnancy and infant allergy risk
A recent study found that maternal avocado consumption during pregnancy was associated with 44% lower odds of infant food allergy at 12 months. Researchers suggest this association may be linked to the fruit’s nutritional profile, which includes fibre, folate, and unsaturated fats that support maternal nutrition and early immune development, although the study did not establish a cause-and-effect relationship.
Better sleep quality
In a recent study, adults who ate one avocado a day for six months reported better sleep quality than those who did not consume avocados daily. Avocados provide nutrients including tryptophan, folate, and magnesium, which play roles in processes involved in sleep, relaxation, and normal nervous system function. While the findings suggest a link between regular avocado consumption and improved sleep quality, they do not prove that avocados were the direct cause.
Rich source of potassium
One serving of avocado contains 487 mg of potassium, compared with 422 mg in a medium banana. Potassium supports normal muscle function, fluid balance, circulation, and the maintenance of normal blood pressure, making avocados a rich dietary source of this essential mineral.
Supports eye health
Avocados contain lutein and zeaxanthin, two carotenoids that support eye health and help protect retinal tissue. Their naturally occurring fats also enhance the body’s absorption of these compounds, increasing their bioavailability.
A berry by definition
Botanically, avocados are classified as berries, although they are more commonly eaten like vegetables in salads, sandwiches, and savoury dishes. They grow on evergreen trees that can remain productive for several decades, with some continuing to bear fruit for more than 50 years under suitable conditions.
Ancient history
The word avocado is derived from the Nahuatl word ahuacatl, the language spoken by the Aztecs, reflecting the fruit’s long cultural history in Central America that stretches back centuries.
More than 500 varieties
Hass is the best-known avocado variety and the one most commonly sold in supermarkets because of its flavour, creamy texture, reliable ripening, and suitability for transport. However, it is just 1 of more than 500 avocado varieties grown worldwide. Many producing countries also cultivate green-skinned varieties that remain green even when fully ripe.
Nutrient dense fruit
Avocados provide healthy unsaturated fats as well as fibre, folate, potassium, vitamins K and E, and a range of other essential nutrients, making them one of the most nutrient-dense fruits.
Sustainability efforts
The World Avocado Organisation says avocados have water requirements comparable with those of many other fruit crops, relatively low pesticide exposure compared with many fruits and vegetables, and are increasingly being produced using more environmentally conscious farming practices. It says growers continue to invest in advanced agricultural technologies, ethical practices, and more sustainable production methods to help reduce environmental impact.
To mark World Avocado Day, the organisation is encouraging consumers to look beyond familiar dishes such as avocado toast and guacamole and explore the fruit’s versatility, nutritional value, and long cultural history, alongside emerging research into its potential health benefits.
