Japanese scientists have found in onions, sulfur compounds that are easily absorbed by the body and can have a beneficial effect on human memory.
 

 

Scientists have conducted a number of scientific experiments examining the effect of onions on the human body. It turned out that the sulfur compounds in onions, which give the specific smell, increase the sensitivity to positive emotions and help restore memory.
 


 

Sulfur compounds enter the bloodstream from the digestive system, and from there are transported to brain tissue, where they stimulate the work of nerve cells.
 

 

According to the authors of the study, the best to stimulate memory and cognitive functions is the mix between onion and honey, and the combination is suitable for older people prone to sclerotic changes.


Another study conducted by Dutch researchers shows that spicy vegetables can protect against hay fever. This anti-allergic effect is due to the querceptin contained in onions - a natural anti-histamine and anti-inflammatory agent.


According to experts, onions contain three times the amount of the substance compared to kale and ten times more than broccoli.
