Everyone loves a good cup of hot chocolate, except those weirdos who don’t, but now it seems this tasty treat could actually have tremendous benefits other than its deliciousness.
Memory deficit usually comes hand in hand with old age. To shed some light onto this problem, scientists at Columbia University carried out an experiment on volunteers aged 50 to 69. These people were divided into two groups; one was given normal hot cocoa, whilst the other was given the same beverage but with increased amounts of flavanol. Flavanol is a chemical commonly found in chocolate, but which also appears in vegetables, fruits and even tea.
Before the investigation started, the patients had an MRI scan taken, and went through a memory test. In it, the volunteers were shown a group of about 40 shapes, and after a minute, they were shown a larger group of shapes, in which they had to recognize the previous ones. During the three months the study lasted, they were given two cups of the drink every day. After this period of time, MRI scans were taken again and the subjects repeated the test.
The results were astonishing. After being given this high-flavonol diet, the patients of the study had improved their memory by a highly considerable amount. It had even become similar to that of a person 30 years younger, as shown by the memory test. The MRI scans also revealed some striking information. There was an increased blood flow in the dentate gyrus of the patients, an area of the brain in the hippocampus, by almost 20%, which had been previously related to memory problems in elderly people.
But if you’re between 50 and 69 years old, don’t start stuffing yourself with chocolate. The flavonol content of those drinks which enhanced memory was of 900mg, which is 90 times as much flavonol as a normal chocolate bar. However, it is still an interesting discovery, which most scientists agree should be investigated further, in greater trials, and with more variables considered.
