When I’m with my love, a situation that
happens: we’re there, sitting. Minding our own business. Then suddenly she
stands up, eyes wide open and says: And then she runs to the fridge to get some
chocolate and I’m like “kay”. How does the brain tell us what we want to eat? Why sometimes we want meat, others we want sweet, others soup and sometimes we don’t even want
to hear the name of one of these things? Well locally Carlos Ribeiro and team might have just found an answer to that by observing flies. The researchers took a bunch of flies and for three days
they gave them a food which didn’t contain a specific amino acid useful to digest it.
Three days later they gave them two kinds of food: one normal and one
with the substance they were missing. The flies were preferring the latter.
So the researchers said: “Okay now we know that files act like us. They know what kind
of food they need and eat accordingly”. Next step: they raised the bacterial flora of
some of these flies and what happened now is that these flies started to
ignore the food they needed. And this is potentially a breakthrough. Because now
we know that what orders us to eat this or that food is not (*initially) the brain
but the bacteria in our guts. Of course inside flies guts there are 6 types
of bacteria. Inside humans there are 500 to 1000 kinds. And while the research
on this might be just the beginning, once identified that kind of bacteria
we’ll be able to create a pill able to suppress it. So if we are trying
to lose weight – or to gain it – this will be of huge help. Maybe in 30 years when
someone will offer us some chocolate we will no longer say “I’m fine”. But we’ll swallow a pill and say
“No, my bacteria are fine”. Subscribe for similar videos three times a week!
