\nWe humans are living longer and longer. Just a few decades ago, people in their mid-sixties were considered old; they were usually retired and lived a quiet, tranquil life. Today, most of us want to stay active well into old age, travel… in short, enjoy life. But what determines whether and to what extent we remain fit and agile into old age? Proteins, the building blocks of our lives, play an essential role here. Because it has now also been scientifically proven: older people need more protein than previously thought. Seniors in particular should therefore make sure they have a good protein supply.
\nOne foundation of our life is cell division. It enables our growth and ensures that our organs or injured tissue regenerate again and again. With every cell division, the so-called telomeres, the ends of the chromosomes in the cell nucleus, become a little shorter. Once a critical minimum length is reached, the cells can no longer divide or they die. This process is one of the most important foundations of the extremely complex aging process. By the way: an unconscious lifestyle with stress, an unhealthy diet, little exercise, and/or smoking can accelerate the shortening of telomeres. Too much UV radiation, too little sunlight for the body’s own vitamin D production, medications, or free radicals can also cause lasting damage to our cells.

\nThe number of cells in many organs noticeably decreases over the years, which also affects their ability to function. Nerve cells in the brain and immune cells also decrease with advancing age and therefore work more slowly. Aging also becomes noticeable in our sensory organs and musculoskeletal system: bone density decreases, the vertebrae change, cartilage tissue becomes thinner, ligaments and tendons lose elasticity, and connective tissue becomes slack. Our skin becomes more elastic and thinner. Hair loses its color pigments, becomes finer, and partially falls out. In addition, there is age-related loss of muscle mass, which usually begins as early as around the age of 30.
\nFor a long time, minor aches and pains, as well as diseases associated with aging, were regarded as natural side effects of this aging process. Today we know that most of these conditions are caused by malnutrition or poor nutrition in the sense of an inadequate supply of nutrients. Protein deficiency in particular leads to far-reaching consequences for our health, especially in advanced age.
But first, the good news to reassure you: it is in our own hands! Because if most age-related complaints and diseases are the result of malnutrition, it is also possible to reverse this process through an appropriate supply of nutrients!
\nThe causes of malnutrition in old age are varied. Not only do our eating habits change over the years due to altered chewing ability, taste and smell perception, lower energy expenditure, or declining appetite; the body’s own digestive and detoxification powers, and thus the ability to utilize protein, also decline more and more with increasing age. In addition, there are often illness-related problems such as difficulty swallowing, chronic pain, or loss of appetite and gastrointestinal complaints as side effects of medications.
The result: in old age, we eat an unbalanced diet or less than we did when we were young. This can easily lead to an undersupply of essential proteins, vitamins, minerals, and trace elements, causing muscle mass to break down and the immune system to become increasingly weakened. We become more susceptible to infections and other diseases.
\nProtein deficiency in particular has devastating consequences in old age. Because without proteins, nothing in our body works. As the building blocks of our lives, proteins or amino acids are absolutely essential for our muscles, ligaments, and bones, but also for our immune system and our entire metabolism. Adequate protein intake is therefore of central importance in old age.
\n\n\n\nThe following symptoms may indicate a protein deficiency in older people:
\n\n\n\nAt first glance, the logical consequence would be to change the diet toward foods low in sugar and carbohydrates and instead rich in protein. However, we are convinced that most people will find it rather difficult to change cherished eating habits in advanced age. In addition, there are other reasons which, in our experience, absolutely argue against suddenly eating more dietary protein at 60+:
Reduced kidney function in old age
Compared with their younger years, a 70-year-old person has only 30 percent of their kidney function left. The kidneys also have less and less cell mass as age progresses. Accordingly, the volume and weight of the kidneys decrease, and with them, of course, their ability to excrete nitrogen waste.
