Some avocados also contain brown fibres or stringy strands running through the flesh. These are called 'vascular bundles', explained Ms Alsing. 'They carry nutrients and water to help the avocado grow and are usually seen in fruit from immature trees,' she said.
They can also appear when avocados are left on the tree too long and begin to over-ripen. At that stage, the pit starts to germinate — the first step in turning into a new plant.
'The vascular bundles further develop to nourish the seed,' Ms Alsing added. 'They may be a bit stringy, but they're completely safe to eat.'
