In what could be claimed a research into the sugary secret of temptation,scientists have discovered what makes cakes and desserts still look good even when people are full to bursting.
Their study has found that it is down to ghrelin,a hormone our bodies produce when people are hungry and it has shown that the chemical also works on the brain to make people crave for high-calorie foods even when they are full.
Just like sweet puddings,it is hard to resist. Its feelgood effect can be as intense as that of cocaine or alcohol,say the scientists.
The study was carried out by a team from the University of Texas Southwestern Medical Centre. Tests on mice — whose brain pleasure centres are similar to ours showed that raised levels of ghrelin made them prefer fatty foods.
Lead scientist Dr Mario Perello said the study could explain “why someone who is stuffed from lunch still wants to eat that high-calorie dessert”,the ‘Daily Express’ reported.
Co-scientist Dr Jeffrey Zigman said: “We have shown there may be situations where we are driven to seek out and eat very rewarding foods,even if we’re full,for no other reason than our brain tells us to.”
The study is to be published in the ‘Biological Psychiatry’ journal.
