Did You Know That Bacteria In Our Intestines Actually Determine What We Want To Eat?


Choosing the right nutrients to consume is essential to health and wellbeing across species. However, the factors that influence these decisions are poorly understood. This is particularly true for dietary proteins, which are important determinants of lifespan and reproduction. You think that you're in control of what you want to eat but research suggests otherwise. Let's take a closer look at how your body chooses what you want to eat.

According to recent research, it is possible that the signals that are sent to your brain about what you want to eat might be sent from your intestines.


The source of these signals is not the intestine itself, but of course bacteria in your intestines. Now stand firm, we are starting our journey on havin very interesting information successively.

Experiments on fruit flies, it has been reported what animals prefer to eat and when to eat it.


According to the results of the reports, what they choose to eat is determined not by the decisions taken in their brains, but by the decisions of the bacteria living in their bodies.

For example, the experiment team first fed these fruit flies with food that didn't contain essential amino acids.


This was observed in earlier experiments in which food products have an appetizing effect on yeast fungi in fruit flies due to their poor nutritional value. They are also known to have negative effects on fertility.

Fruit flies that didn't have bacteria consumed a lot of yeast mushroom as expected.


But the fruit flies, which have bacteria in the digestive system, didn't show any extra appetite against the proteins and consumed less yeast mushrooms. Moreover, unlike flies in the first group, their fertility rate didn't decrease. So they went on as if nothing had happened to their lives.

According to experts, the reason for this is that the bacteria program themselves according to the nutritional needs of the body they are in.


How do they manage to do that? The first idea that comes to mind was that the bacteria produced the missing amino acids; But it was soon understood that this was not the case. Instead of this method, bacteria effected the brain to produce appetite against specific foods.

Of course, as humans our microbiome is larger and more diverse than fruit flies.


But this is still an important discovery for the connection between the stomach and intestines and the brain. It was already known that these three organs were in constant contact with the help of hormones, neurotransmitters and other chemicals.

Moreover, myomis is called the "second brain" because of the hundreds of millions of neurons that make up the enteric nervous system.


Therefore, it is highly probable that 100 trillion bacterial strains in our digestive system are affecting the possession of the body they are using.

Moreover, researches on mice in past years support this end result.


In that study, 20 minutes after eating, the bacteria in the digestive system of mice were found to produce proteins that signal they were full to the brain. Furthermore, when these proteins were injected into mice that had not eaten anything, the mice lost their appetite.

It is probable that the bacteria in our bodies are also sending signals to our brains that we shouldn't eat more food.


Moreover, the capabilities of the bacteria don't end with that ... According to another research, they can even play with our taste receptors so that we like the food they want more.

In other words, bacteria manipulate a lot of things.


Fortunately, while they think about themselves, they care that the body they're in remains in good shape. But their understanding of  "good" doesn't always match our wishes, so at 2 a.m. you find yourself looking for something in the fridge ...

In a nutshell, when you look at the menu, what you actually do is to ask your bacteria what they want to eat ...


We will have a clear answer to this later. But the data on it isn't very strong for now.
