Cinnamon may do much more than please your taste buds. Several scientific studies have shown that the brain may derive significant benefits from cinnamon. One study showed that smelling cinnamon can improve attention and memory in the short term. Other studies show that the compounds in cinnamon may be beneficial for Alzheimer’s prevention. A brain that suffers from Alzheimer’s has “plaques” and “tangles” that harm or kill brain cells. Different groups of researchers have shown that cinnamon may prevent the formation of both the plaques and the tangles found in the Alzheimer’s brain.
