As bacteria in the gut can affect memory?
Source:
After many years of research, scientists came to the conclusion that memory is influenced by many factors — from obesity to specific products. For example, those who regularly consume hot peppers, eventually falls ill with dementia (deterioration in memory). It turns out that pepper is one of the reasons for the deterioration of memory in old age. But not only the food, as it turns out, can make us more forgetful. Even certain bacteria in the gut can improve the memory, and the lack of them, on the contrary, contributes to the development of dementia.
This is the conclusion of the National laboratory behalf of the Lawrence Berkeley. They conducted a series of tests on mice: the rodents were released in the experimental chamber, where they chose which of two compartments them to run. In one compartment of the mice gets a small discharge current that they remember that there does not need to go, and subsequently selects only the first compartment.
How to improve memory
The Experiment was repeated every few days, only one group also gave food from lactobacilli. These bacteria live in each person, are found in mammals and represent a significant part of the intestinal microflora. They produce lactic acid that inhibits growth of many pathogenic bacteria and fungi. However, these bacteria were confirmed more purpose — they improve memory.
After 5 weeks of the experiment the scientists found that mice who ate food with lactobacilli, the memory was better than their relatives. If a normal mouse, who also remembered the "dangerous" compartment, ran back after fifteen minutes, the rodents on special food was there only in 3.5 minutes. To understand whether these bacteria affect the cognitive abilities of animals, the researchers conducted analyses of their feces, plasma, blood and brain. It turned out that analyses all the mice were identical, with the exception of one substance — lactate, concentration of which was higher in those who ate the special food.
Lactobacilli is able not only to cure intestinal infection.
Use of Lactobacillus
According to the authors of a study in the theory of lactobacilli can be used for therapy for memory impairment in humans. However, to find out, you will need to conduct additional studies on the people that intend to make scientists. I hope, without the experiments with the discharge current.
Nowadays some species of lactobacilli (they Lactobacillus) is used in the production of yogurt, milk, cheese and other dairy products. Lactobacilli are involved in the processes of pickling vegetables, preparing marinades, and other products. In addition, strains of lactic acid bacteria used in the production of medicines — probiotics designed to restore the normal microflora of the intestine and the female genital organs.
It is Proved that the preparations of lactic bacteria improve metabolism and their use for improving memory can be another proven benefit of these bacteria.
Does this Mean that eating dairy products, in humans improves memory? It is difficult to say for sure, however the use of such products in any case is, and rather big. The human body metabolizes contained in milk and dairy products calcium is easier than the calcium that is in other foods, including green vegetables. But this does not mean that you can drink a glass of kefir in the morning and evening to eat a lot of fatty foods and drink alcohol — balanced often much more important than the use of any one product in the food.
In addition, intestinal bacteria also influence what traits a person receives throughout life. For example, in organisms sociable and energetic people, scientists previously found a large number of bacteria Akkermansia, producer Lactococcus and Oscillospira. People with a large number of such bacteria are more open to other people and often are the souls of the company. So we eat plenty of sauerkraut, bananas and onions, because that is where a lot of these intestinal flora.
A Couple of years ago biologists from Sweden and the USA found that some bacteria in our body . Scientists from the University of California at Berkeley in turn found several enteric bacteria with similar characteristics. To them, the researchers found, include Listeria and lactobacilli. This can help you be more effective in fighting intestinal infections due to the creation of new drugs.
Between the gut and the brain there is a strong link.
