I actually feel some difference in my day when I have some honey in the morning. It's excellent coffee sweetener also. It's so good for digestion. And it's perfectly safe to eat they honey in large quantities without having any side effects. But the honey has to be raw otherwise you will be suffering from high blood sugar later.
It's quite hard to find out if the honey is hard but raw honey crystalizes faster than heated honey. Honey is only heated to keep it in liquid form for longer.
