The most abundant amino acid of our blood – acquired through a protein -rich diet – has the power to keep the retina thick and healthy. But calm down, you don’t have to totally forget the carrots.
As photoreceptor cells From the retina, cones and rods, are responsible for converting light into neural signs that the brain interprets as vision. When they die, either due to age or disease, they can lead to vision.
As it writes, traditionally, researchers focus on how photorecers use glucose for energy. However, as retinal cells need so much metabolic support, a group of researchers at the University of Michigan decided other compounds involved in your health.
In a study in 2021 in Communications Biologythe investigators had already pointed to the amino acid glutaminebecause it is the most abundant amino acid in the blood.
Glutamine is naturally synthesized in the body and can also be acquired mainly from all sources of animal protein.
That is, meat and fish hide secrets of eye health.
And yes, it is true, the carrots also have a little – Therefore, contrary to what the title of the article suggests, No need to forget them totally.
Os dry fruits, cereals, legumes and vegetableslike spinach and kicks, they are also good carriers of this amino acid.
In their experiences, made on the fringes of a new study in May in the Cell BiologyTo test the role of glutamine in vision health, researchers used genetically modified rats that did not have glutaminese enzyme, which converts glutamine into the amino acid and glutamate neurotransmitter.
Compared to a control group whose glutaminase was left intact, the tested rats presented a rapid thinning of your retinas corresponding to a loss of photorecers.
