Honey is one of the only food substances that does not spoil. It’s difficult for bacteria to thrive in honey due to its high concentration of glucose and fructose. After a while, honey may look like it has gone bad because it crystallizes. However, when honey hardens, you just need to heat it back up. Honey isn’t bad for you, either. In fact, many scientists believe that humans could live on honey alone. Honey has many health benefits. It can relieve a sore throat and boost the immune system. It can also nourish your skin and relieve indigestion. Sweet!
