About 1 out of 3 adults, exceeded 50 years, suffers from sarcopenia, a progressive loss of muscle mass and strength, which can affect the energy of a person and the ability to perform daily activities.
Protein consumption stimulates the body's cells to produce new proteins that feed the muscles, but many people, especially the elderly, can not incorporate adequate sources of protein in their daily diet.
The current US recommendations relating to recruitment of protein in the daily diet are 0.8 grams of protein / kg body weight (about 56 g of protein per day for a person weighing 70 kilos).
IY Kim, from the University of Arkansas (Arkansas, USA), and colleagues enrolled 20 healthy adults, aged between 52 and i75 years, each of which was randomly assigned to one of four groups over a period test of four days. Two groups ate the RDA of 0.8 g / kg per day of protein: a group has had a distribution of proteins during meals (33% of the total protein at breakfast, lunch and dinner) and the other has had an uneven distribution of the protein at meals (15% for breakfast, 20% and 65% at lunch and dinner). The other two groups ate a double portion of protein than the RDA (1.5 g / kg per day of protein) following percentage distributions as the first two groups. The group that consumed twice the RDA has had an integration with a milk protein concentrate (equal parts of whey and casein), to ensure the objectives achieved of 1.5 g protein / kg per day.
The team observed that the distribution of proteins through meals does not have a significant impact, but the total amount of protein consumed him. The study authors say: "The rate of protein synthesis was increased with an increase in the amount of protein, regardless of distribution models," concluding, therefore, that "The daily intake of protein is important for the maintenance of muscle mass, especially in older people, exposed to greater risk. It does not matter how proteins are divided over the day / meals and it is recommended that the RDA rules provide medical "
