A team of researchers from South Korea, representing Phohansky University science and technology found that the taste and smell of different foods trigger mechanisms that accelerate the aging process and reduces life expectancy. However, as scientists say, this effect does not depend on whether the food is absorbed by those who feel its smell.

The taste and smell are considered fairly closely related to each other feelings. As with other senses, they arise from living beings because in sensory neurons are activated by the body. Previously, it was also found that sensory neurons play a role in aging in many animals, but a direct link gustatory and olfactory sensations with how quickly a living being is aging, according to scientists, has not been studied too. It was known only that the damage to sensory neurons triggers activation of the anti-aging FOXO protein. Experts decided to hold a series of experiments on roundworms, or nematodes, to better understand the nature of this relationship

As the first experiment, the smell and taste of food provoked in roundworms the hormone called “insulin-6″ raising the level which reduces the FOXO activity and, consequently, accelerates aging. Further investigation revealed that a similar chain of events starts and if the work of sensory neurons involved in the formation of taste and olfactory sensations, activated artificially by using a special light, even if the nematode with nothing to eat.

Researchers They admit that they have received the conclusions can be applied not only to roundworms, but also to the people, even though such an assumption, of course, still requires further confirmation. The work of scientists published in the journal Genes & amp; Development.

This is not the first recent study in which scientists explore the mechanisms of human aging, resorting to experiments on nematodes. Recently, a team of specialists representing the Indiana University by studying roundworms could compile a list of substances on the basis of which it would be possible to create longevity and anti-aging drug.
