A new study has shed light on why people crave for sugary or starchy foods, saying that brain senses how much glucose is reaching it and then prompts animals to seek more if it detects a shortfall.
Researchers at Imperial College Londonfound that people have a deep-rooted preference for glucose-rich foods and seek them out, the Daily Express reported.
Dr James Gardiner, who led the study, said that brains rely heavily on glucose for energy and it's clearly a very important nutrient but in our evolutionary past it would have been hard to come by.
