Yes, you can eat brown avocado in most cases. The browning occurs due to oxidation, a natural reaction when the flesh is exposed to air.
While the color may be unappealing, the taste and texture remain relatively unchanged for a short period. You can scrape off the brown layer if you prefer a fresher appearance.
However, if the avocado has a sour smell, slimy texture, or shows signs of mold, it's best to discard it, as these indicate spoilage
Overripe avocados can sometimes have brown streaks inside, but they are generally safe to eat unless accompanied by unpleasant odors or tastes.
To prevent browning, store avocado with the pit intact, brush the exposed flesh with lemon juice, and seal it in an airtight container in the refrigerator
This slows oxidation and keeps it fresh longer.
In short, brown avocado is usually safe to eat, but always use your senses to ensure it’s not spoiled before consumption.
