Why should the diet contain an adequate amount of protein?
When people are very little protein Record, this can increase with age cognitively to lead. A sharp decrease in protein intake threatens to significantly reduce mental performance.
In a new joint cohort study by experts from Hebei Medical University and the Nanjing Medical University investigated the relationship between changes in protein intake from different food groups and cognitive impairment in older participants. The results were published in the English-language journalNutrientsreleased.
Almost 7,000 older adults were screened
Participate in the investigation in total 6951 people Part which is lifetime at least 65 years old They did not suffer from cognitive impairment. The team explained that the questionnaires were used to determine the frequency of protein intake from different food groups.
Questionnaires were completed by the participants at the start of the study and during several follow-up examinations and were developed during the medical follow-up period 1,202 one co cognitive impairmentResearchers report.
The effect of protein intake
Experts have found that improving total protein intake protects against cognitive impairment. At the same time, the team also found that it appears to be particularly bad for people’s cognition Extreme steepness from eating protein on an animal basis an offer.
This increased the risk cognitive impairment a 48 percentThe researchers reported that when there was a sharp decline in animal protein intake compared to the participants, their protein intake underwent stable changes.
Plant protein more beneficial for cognition?
The results of the study indicate that plant protein It is more useful for maintaining cognitive functions than animal proteins. Be one in general Improve protein absorption but with one Less risk The team said it was linked to cognitive impairment.
What are the functions of proteins in the body?
Proteins perform a variety of functions in living organisms, such as regulating metabolic processes. Proteins are also important building blocks musclesAnd highhair, nails and other tissues.
Proteins play a role send signals, which is partly important for cognitive processes. For example, some proteins are involved in and influence the transmission of signals in the brain to learn and the memory. In addition, proteins are also important in the formation of synapses and the building of neurons that support cognitive functions.
For example, for ADORA2B protein It is already found to prevent cognitive and auditory dysfunction. The protein appears to slow cognitive decline and has an anti-aging effect on the brain. (Please refer This anti-aging protein keeps you mentally fit).
The diet should include an adequate amount of protein
The findings of the new study show that older adults in particular should be careful about them feed Get enough protein. Researchers recommend plant proteins to halt or at least slow the decline in cognitive abilities that occurs with age. (like)
