Avocados have become a staple at breakfast and lunchtime, not just across the UK but worldwide. They are a fantastic source of healthy fats, incredibly versatile, and delicious. Like many, I always grab one or two during my weekly shop. After years of buying them, I have a decent eye for spotting perfectly ripe avocados. Storing them, however, is another matter. I often only get through half, only to find the remainder covered in unsightly brown spots the next day. Depending on how bad it looks, I scrape away the discolored bits and eat the rest. They are not cheap, and I want full value for money. Recently, I questioned whether this is safe or if I am risking illness.
Experts Weigh In
I consulted several experts to settle the matter once and for all. They all came back with the same advice: brown avocado is generally safe to eat.
Why Avocados Turn Brown
Destini Moody, a dietitian at Flex Therapists, explained that browning is a natural process called oxidation. "Once an avocado is cut open and exposed to air, it begins to turn brown," she said. "If only the surface is brown, it is usually still safe to eat. You can scrape away the brown layer or mix it into the green flesh. The browning itself is not normally a food safety problem."
Melissa Jaegar, head of nutrition at My Fitness Pal, agreed. "It is a surface reaction and the green flesh underneath is perfectly fine to eat. Much of the aversion is psychological; most people notice very little difference in taste if they cannot see the color change. So do not let the look of a browned avocado send it to the bin."
Vassiliki Sinopoulou, Registered Dietitian and Lecturer at the University of Lancashire, confirmed there are no health risks linked to eating brown avocados. However, she warned that spoiled avocados are different. "If an avocado has been left out or stored too long, it may spoil. Signs include a bad smell, mold, excessive softness, or a slimy texture. In those cases, discard it, as spoiled food can cause gastrointestinal illness."
How to Keep Avocados Fresh
The experts agreed that scraping away discolored flesh is acceptable, but I wanted to know how to preserve the fruit after slicing. They largely echoed one another: lemon or lime juice is the ultimate secret ingredient.
Gabriela Peacock, nutritionist and founder of GP Nutrition, said: "To keep avocados fresher for longer, store leftovers in an airtight container in the fridge. Adding a squeeze of lemon or lime juice can also help slow down browning."
Carly Campbell from Bite Sized Bash suggested creating a protective barrier by brushing the flesh with olive oil or sealing it tightly with cling film before refrigerating, ensuring the stone remains in place.
So, before you resign another browning avocado to the bin, scrape away the affected areas. If it is still green underneath, you are absolutely fine to eat it.
