“Man is what he eats” – this phrase is particularly fair to the squirrels. Derived from food proteins are split into amino acids, which our body builds its own proteins. It is well known that protein consumption stimulates the cells of the body to build its own protein.
In older people, slows metabolism and decreases the effectiveness of muscle-building body, as a result, they not just lose weight, but become inactive, lethargic, increased risk of fractures, reduced quality of life.
A new study published in the journal of physiology-endocrinology and metabolism, aimed to find out whether the net profit of the protein in the body from
the number and time of protein intake.
According to the current recommendations of nutritionists, an adult should consume 0.8 gram of protein per kilogram of their weight, approximately 62 grams and weighs 77 kg. the Elderly, according to some, needs to consume 0.4 g/kg protein for each meal (31 g 3 times a day with the weight of 77 kg). This is a much larger protein than the recommended dietary recommendations. Researchers from the Centre for translational research in aging and longevity Institute on aging at the University of Arkansas conducted an experiment to find out whether greater daily protein intake to greater net protein synthesis in the elderly. They also considered the time of protein consumption, the difference in the synthesis process in which cells make more pure protein.
For the study, we selected 20 healthy people aged 52-75 years who were divided into 4 groups randomly. Two groups were consuming the recommended 0.8 g/kg of protein:
in one group the amount of protein was distributed evenly throughout the day (33% for Breakfast, lunch and dinner), the second had uneven distribution of protein throughout the day (15% Breakfast, 20% lunch 65% dinner). The other two groups consumed 1.5 g/kg body weight (one was even distribution throughout the day, another uneven).
The results of the study showed that the net protein synthesis of the organism is directly dependent on the total amount of protein consumed, while the distribution of protein throughout the day has no significant effect.
Thus: the amount of dietary protein intake, but not the structure of intake, affects net protein balance primarily through differences in protein synthesis in the elderly.
