Are you throwing away the healthiest bit of the avocado, the SEED? The stone is the 'most nutrient-dense part', expert reveals

Many people toss avocado seeds - assuming they are inedible. However, New York City nutritionist Amy Shapiro told Daily Mail that the stone of the avocado is actually the most nutrient-dense part. 

The seed contains 70 per cent of the avocado's antioxidants - as well as high amounts of fiber. It can be prepared for consumption as a powder, which can be added to smoothies, juices and yogurt.

To prepare an avocado, first remove the seed as you normally would (top left). 

Then, tap a sharp knife into the seed and twist. Rinse the seed, then place it in an oven pan and dehydrate at 120 degrees Celsius for two hours (top center). 

Once the seed is cooled, discard the dry outer skin (top right), cut the seed in half (bottom left) and dice it into small pieces (bottom center). 

Then pieces can then be blended into a fine powder (bottom right), and stored in the fridge.
