"People are getting old, and they are getting less and less useful" Uncle Wang's physical condition is getting worse and worse this year, and he has always been sick recently.
In the first few years of retirement, he could still accompany his grandson to run around and play all day long, and now his health seems to be worse than a year.
I often forget the things that my daughter-in-law confesses in a blink of an eye, and recently I was complained by the neighbor next door because I spoke too loudly behind my ear...
"Obviously, I have always been in good health before, why did I feel that all kinds of problems have found me when I am 70 years old?"
1. The three age stages usher in "cliff-like" aging
According to the definition given by the WHO: "Aging is the gradual accumulation of various molecular and cellular damage in the body over time".
The authoritative journal "Nature Medicine" once published a study, the experiment by testing 2,925 plasma proteins in subjects aged 18-95 years old, found that at the age of 34, 60 and 78 years old, the plasma proteome in the human body will fluctuate dramatically, and the relationship between age and aging "three physiological turning points" was found.
The study found that aging at the age of 34 is mainly manifested in the "face", while the cliff-like aging after the age of 60 or even after the age of 78 will be manifested in some health problems.
A joint study by the Chinese Academy of Sciences and Wenzhou Medical University found that women's "aging nodes" are mainly at the age of 30 and 50, which are the two most important time nodes for women's aging performance.
At the same time, aging will also increase the occurrence of diseases, and the process of aging is the process of gradual weakening of body functions, of course, it is not excluded that diseases also affect the process of aging.
But don't worry too much, aging is a necessary process for human beings, and only by understanding it comprehensively and getting vaccinated can we overcome the fear of the unknown.
2. There are 4 conditions in the body, which means that you are starting to get old
In fact, all the degenerative changes in our body are traces of time, and as we age, we may gradually find that the metabolic rate is not so good, the body's immunity may be reduced, and it may also be accompanied by various aspects of performance.
1. Body change
The most obvious change is shortening, mainly because the shortening of the spine affects the change in height, and there is also kyphosis due to abnormal bone metabolism, resulting in hunched back. In addition, there are some elderly people who will be short and have longer hands and feet.
2. Changes in the skin and its appendages
To put it simply, the skin has deteriorated, the elasticity has weakened, and warts, pigment spots, wrinkles and other conditions will appear, and the hair will also lose its elasticity, be easy to break, and hair loss will occur; Due to the decrease in the number of cells and sweat glands and capillaries, the skin becomes dry and becomes less functional.
3. Deterioration of behavioral and cognitive abilities
The process of human aging is also accompanied by the decline of brain function, starting from the age of 30 or so, it will be obvious that the speed of processing information will decrease, and there will always be a loss in work and life, exercise ability will also decrease by 15%~30%, and coordination will also be reduced.
4. Musculoskeletal changes
The muscle mass of the body will gradually decrease when people get old, and the muscles in the thighs will decrease the most, so many elderly people will have osteoporosis, balance problems, falls, fractures, etc. due to musculoskeletal changes. Therefore, it is quite important to maintain daily exercise to prevent aging.
3. All kinds of diseases come when people get old? These 3 nutrients must be kept up
People will also be targeted by many diseases when they are old, because at the same time as the function is declining, the defense is also weakening, and if the daily nutrient intake is insufficient, it is more likely to lead to the occurrence of geriatric diseases. Therefore, it is necessary to pay attention to the intake of these key nutrients in the daily diet.
1. Omega-3 fatty acids
Omega-3 fatty acids, which are known as universal supplements, have shown significant efficacy in many fields such as cancer prevention. The New England Journal of Medicine (NEJM) also published a study showing that the risk of cardiovascular disease was greatly reduced in subjects using omega-3 fatty acids, and researchers said that the intake of omega-3 fatty acids had a significant effect on preventing cardiovascular disease and lowering triglycerides.
Fish is the most common food rich in omega-3 fatty acids, especially fish that are high in cold water, such as salmon, mackerel and anchovies. In addition, walnuts, soybeans, chia seeds, rapeseed oil, and cauliflower are also contained and can be consumed appropriately.
2. Protein
Protein is an important part of maintaining the normal function of muscles, bones, skin, organs, and tissues. Daily protein supplementation is of great significance for the elderly to alleviate metabolic problems and gain muscle.
Nutritionists recommend supplementing with 0.8 grams of protein per kilogram of body weight by weight.
3. Iron nutrition
Iron deficiency will also aggravate a series of problems such as resistance and memory in the elderly, so it is important to supplement iron in moderation, and you can eat more iron-rich foods every day.
In general, while paying attention to nutritional intake, it is also necessary to prevent possible disease risks, maintain a healthy posture, nourish the body and mind, and feel comfortable physically and mentally, and the body will naturally be well.
