Unfortunately all honey is not equal. A lot of the health giving properties of raw or natural honey are completely removed by the processing it goes through before it makes it on to the supermarket shelves. What is required by supermarkets is a honey which will remain runny and clear for a long shelf life and so often the honey is heat treated.
Firstly, the honey is heated to around 71 degrees C which keeps the honey liquid indefinitely. The honey is then blasted through a fine mesh removing all grains of pollen and along with them all their health giving benefits and turning the honey into a sugary syrup.
Natural local (or raw) honey can be found in plenty of places, local farm shops, farmers markets, butchers and greengrocers to name a few. The best way to find a source of natural local honey is to find your local beekeeping association.
