A USA researcher’s university of Alabama grew precancerous lung cells in a laboratory and then exposed the cells to glucose, a common component of human diet. The team varied the level of exposure of the cells to glucose.

And after some of hours they realize that healthy lungs cells that were exposed against the lower levels of glucose lived longer than those to normal levels.

Many precancerous cells died when the glucose exposure was limited.  All researchers realize that this is because lower glucose levels decrease the activity of enzyme telomerase, which is involved in division of cells and increased that of P16.

Author (Trygve Tollefsbol) of the study said that we were able to track that all cells ability to divide while also monitoring the number of surviving sells. And after the pattern that was revealed to us showed that restricted glucose levels led the healthy cells to grow longer than is typical and caused the precancerous cells to die off in large numbers.
