Chronic kidney disease (CKD) is a prevalent health issue affecting millions of people worldwide, particularly those in low-income and lower-middle-income countries. However, a recent study suggests that following a diet rich in proteins may help lower the risk of death among individuals with CKD. This finding sheds light on the potential benefits of protein intake in managing and potentially improving outcomes for those with kidney disease.
The study, led by researchers from Karolinska Institutet and Stockholm University in Sweden, involved 8,543 community-dwelling adults aged 60 and older. These participants were followed up for mortality over a period of several years. The results, published in the journal JAMA Network Open, indicated that a higher intake of total, animal, and plant protein was associated with lower mortality in older adults with mild or moderate CKD. This suggests that protein consumption could play a significant role in improving survival rates among this population.
The researchers pointed out that the benefits of protein intake may be particularly pronounced in older adults with mild or moderate CKD, where disease progression may have a more limited impact on survival. Protein supplementation could potentially reduce the risk of death in older individuals by increasing levels of branched-chain amino acids, which are essential for muscle function and overall health.
Furthermore, a higher protein intake has been linked to various health benefits, including increased muscle mass and strength, slower bone loss, higher bone mineral density, lower risk of frailty, improved cardiovascular function, and better recovery from illness. Conversely, protein deficiency in older adults can lead to impairments in muscular, skeletal, and immune function, putting them at risk for various health complications.
Addressing concerns about the impact of protein on kidney health, Dr. Sudhir Kumar from Indraprastha Apollo Hospitals in Hyderabad emphasized that a diet rich in proteins is safe for the kidneys. He recommended consuming around 1 gram of protein per kilogram of actual body weight for healthy individuals, with variations based on physical activity levels and any existing health conditions. Consulting with a nutritionist and physician for personalized dietary advice is crucial to ensure optimal protein intake and overall health.
In conclusion, the study highlights the potential benefits of protein intake in reducing the risk of death among individuals with CKD, particularly older adults. By incorporating adequate amounts of protein into their diets, individuals with kidney disease may improve their overall health outcomes and potentially enhance their longevity. This research underscores the importance of nutrition in managing chronic conditions and promoting overall well-being.
