Aging is a complex biological process, which can be divided into two types: endogenous aging and exogenous aging. Endogenous aging refers to the process by which the body naturally declines with age, while exogenous aging is caused by environmental factors such as UV exposure, pollution and lifestyle.
Endogenous aging refers to the aging process caused by internal factors in the body, mainly involving the gradual decline in the function of cells, tissues and organs. Its mechanism is complex, mainly including the following aspects:
1. Oxidative stress
As we age, the level of oxidative stress in the body gradually increases. Cells produce free radicals during normal metabolism, and these unstable molecules attack cell components such as lipids, proteins, and DNA, leading to cell damage and dysfunction. Antioxidant systems (such as glutathione, superoxide dismutase, etc.) can effectively remove free radicals when young, but as we age, the efficiency of this system decreases, leading to the accumulation of oxidative damage, which accelerates aging.
2. Apoptosis and senescence
Apoptosis is a form of programmed cell death that normally helps remove cells that are damaged or no longer needed. However, with age, the regulatory mechanisms of apoptosis may be out of balance, leading to premature death of healthy cells as well. At the same time, the accumulation of senescent cells will release pro-inflammatory factors, further triggering local and systemic inflammatory responses, affecting the function of surrounding healthy cells.
3. Telomere shortening
Telomeres are protective structures at the ends of chromosomes that protect them from damage during replication. Each time a cell divides, telomeres shorten. When telomeres shorten to a certain extent, the cell will no longer be able to divide, and thus enter a state of aging. Telomere shortening is closely associated with a variety of age-related diseases, such as cancer and cardiovascular disease.
4. Change of gene expression
As we age, patterns of gene expression change. These changes can lead to a reduction in the synthesis of key proteins, such as those involved in repairing and maintaining cell function. In addition, the expression levels of some genes associated with inflammation and immune responses may increase, thus accelerating the aging process.
Aging is also accompanied by a decline in metabolic function, including reduced insulin sensitivity and abnormal fat metabolism. These metabolic changes not only affect energy balance, but also may lead to chronic diseases such as obesity and diabetes, and accelerate the aging process.
1. Ultraviolet radiation
Ultraviolet light (UV) is one of the main exogenous factors that cause skin aging. Prolonged exposure to the sun, especially without protection, can cause damage to skin cells. UV rays destroy collagen and elastic fibers in the skin, leading to sagging, wrinkle formation and pigmentation. In addition, UV rays can also trigger oxidative stress, further accelerating skin aging.
2. Pollutants and free radicals
Air pollution, smog, heavy metals, and other environmental pollutants produce large quantities of free radicals, which can damage cell membranes, proteins, and DNA, leading to decreased cell function. Studies have shown that long-term exposure to environmental pollution is closely related to skin aging, chronic inflammation and the occurrence of many diseases.
3. Bad living habit
Bad lifestyle habits, such as smoking, excessive drinking and irregular sleep schedules, can significantly accelerate the aging process. Smoking not only reduces blood flow to the skin, but also destroys collagen, leading to dry skin and wrinkles. Heavy drinking may affect liver function and lead to the accumulation of toxins, which can affect overall health. In addition, irregular work and rest can lead to lack of sleep, affecting the body's ability to repair itself.
4. Improper diet
Eating habits directly affect health and the rate of aging. Diets high in sugar, fat, and nutrients can lead to metabolic disorders, obesity, and chronic diseases that accelerate aging. In addition, a diet lacking antioxidants reduces the body's ability to defend against oxidative stress, making cells more vulnerable to damage.
5. Psychological pressure
Chronic psychological stress can cause imbalance in hormone levels in the body, increase inflammatory responses, and affect immune system function. High levels of stress hormones, such as cortisol, are strongly associated with the development of age-related diseases, such as cardiovascular disease, depression, etc.
Exogenous aging is the result of a variety of environmental factors and lifestyle. By improving living habits, reducing exposure to environmental pollution and taking appropriate protective measures, the exogenous aging process can be effectively slowed down and the quality of life and health can be improved.
In the face of the challenges of skin aging, we can take a variety of measures to slow down the process. Among them, taking oral anti-aging functional foods is a very effective method.
What is anti-aging functional food?
Anti-aging functional food refers to the food that has the function of delaying aging, improving life quality and preventing diseases related to aging. These foods are usually rich in a variety of nutrients and bioactive substances, which can achieve the purpose of anti-aging by regulating the physiological function of the human body. A certain amount of nutrients can be consumed through a healthy diet, but in some cases, we may not be getting enough anti-aging ingredients from our food. Only oral food supplements can provide us with additional nutritional support to help slow down the aging process.
Anti-aging supplements are divided into antioxidant supplements, collagen supplements, plant extract supplements and so on.
- Collagen supplements
Collagen is one of the most abundant proteins in the human body. It exists in skin, bones, joints, muscles and other tissues, and plays an important role in maintaining the structure and function of these tissues. With the increase of age, the synthesis of collagen in the human body gradually decreases, and the breakdown speed is accelerated, resulting in skin sagging, wrinkles, joint pain and other problems. Collagen can be replenished both externally and internally.
Among them, oral collagen supplements usually contain collagen peptides or hydrolyzed collagen, which are small molecules of collagen that can be quickly absorbed by the body to supplement the collagen content in skin, bones, joints and other tissues. In addition to collagen itself, some ingredients that promote collagen synthesis are also widely used in anti-aging supplements, such as vitamin C, copper, zinc, and so on.
- Plant extract supplement
Plant extracts are bioactive ingredients extracted from plants, they have a variety of health benefits, such as antioxidant, anti-inflammatory, antibacterial, immune regulation and so on. In the field of anti-aging, some plant extracts are also widely used in supplements, such as grape seed extract, pomegranate extract, psoralea extract, ginkgo biloba extract and so on. Plant-based supplements often contain a variety of ingredients that can work synergistically with each other to enhance anti-aging effects. However, it should be noted that the efficacy and safety of plant extracts still need further research and verification, and should choose regular products when using, and follow the advice of a doctor or nutritionist.
When it comes to minerals, zinc is essential for the immune system, helping in wound healing and skin repair, and warding off the inflammatory response that comes with aging. Magnesium supports nerve and muscle function, helps relieve stress and improves sleep quality. Through the reasonable supplement of these vitamins and minerals, you can indirectly and effectively delay the aging process, improve the overall health level, and keep the body young and energetic.
- Yeast extract supplement
Yeast extract is rich in a variety of antioxidants, such as selenium and glutathione, which can effectively neutralize free radicals and reduce oxidative stress damage to cells, thereby delaying the aging process. By reducing oxidative damage, yeast extract can protect cells and maintain their normal physiological function. In addition, yeast extract can also improve the hydration and elasticity of the skin, reduce the formation of wrinkles, and make the skin firmer and smoother. Among them, the amino acids and vitamin B groups in yeast extract help promote the formation of new cells and repair damaged cells, thereby improving skin texture and overall health. It is worth mentioning that some yeast strains can effectively synthesize and accumulate ergothioneine, a mitochondrial protective agent, which further enhances its anti-aging effect. Therefore, yeast extract supplements effectively delay cell aging through multiple mechanisms such as antioxidant, promoting cell regeneration, improving skin health, and supporting energy metabolism.
In addition to the above several supplements, there are other types of anti-aging supplements, such as mitochondrial nutrition, enzyme supplements, etc.
How to choose anti-aging food supplements?
There are more anti-aging food supplements, before choosing, we must first understand their own needs, everyone's physical condition, lifestyle and eating habits are different, and may have different problems, such as skin relaxation, wrinkles, joint pain, reduced immunity, etc.; According to your specific situation, choose the right supplement for you. Secondly, some anti-aging food supplements may have quality problems or false publicity; When choosing a supplement, choose a regular product and look at its composition table and production standards. Ensure that products are tested by third parties to ensure their safety and effectiveness. Finally, before using supplements, it is best to consult a doctor or dietitian who can provide professional advice based on your health condition and help you develop a reasonable supplement plan.
The importance of diet and lifestyle
While anti-aging supplements can provide extra help to slow aging, maintaining a healthy lifestyle is just as important. By eating a balanced diet, you can provide your body with the nutrients it needs; In addition, eating more antioxidant-rich foods, such as berries, nuts, and dark leafy greens, can help ward off free radical damage. Regular exercise can not only improve your physical health, but also your mental state. It is recommended to get at least 150 minutes of moderate-intensity aerobic exercise a week, such as brisk walking, swimming or cycling. Combine it with strength training to build muscle mass. Sleep is essential for recovery. Adults should ensure seven to nine hours of quality sleep each night to promote cell repair, boost immunity and improve mental health. With the development of society, the pace of life is accelerated, and the ideological pressure is large, which leads to the acceleration of skin aging, so it is necessary to release the pressure in time.
Anti-aging food supplements provide us with an additional anti-aging pathway. By choosing the right supplement for us, combined with a healthy lifestyle and a balanced diet, we can slow the aging process and improve our quality of life. When choosing a supplement, understand your needs, choose a regular product, follow the advice of your doctor or dietitian, and pay attention to the precautions for use.
