Immunity is the best doctor. Reminder: If you want to improve your immunity, eat these two types of foods appropriately.

 Immunity, a seemingly abstract concept, is actually a powerful force within each of our bodies. It is the body's own "doctor" and a solid barrier against diseases. It silently guards our health and allows us to maintain the vitality of life in various environments.

However, as we age, our immunity naturally declines. At the same time, with the acceleration of social pace, the pressure of career and family is increasing day by day, unhealthy eating habits and poor lifestyles also come along.

These factors may lead to sub-health conditions in the body, challenging our immunity. Therefore, paying attention to health and enhancing immunity has become a task that each of us cannot ignore.

Immunity, a term with profound and important implications, is endowed with the sacred mission of safeguarding life safety in the context of biology. It is like a well-trained army within our bodies, always ready to resist attacks from foreign invaders.

These invaders may be bacteria, viruses, and other microorganisms, or substances that can cause harm to our bodies. Immunity is a self-protection mechanism of the body. It can protect our bodies from harm by identifying and eliminating these foreign substances, serving as a solid barrier to safeguard our health.

At the same time, immunity can also remember these foreign substances, allowing it to respond quickly and effectively prevent the recurrence of diseases when encountered again.

However, immunity is not omnipotent, and it may be overwhelmed when facing some powerful enemies. At this point, we need to enhance our immunity to improve our body's resistance, which can be achieved through maintaining a healthy lifestyle, a reasonable diet, appropriate exercise, and a good mindset.

In the face of various viruses and bacteria, the immune system can rapidly identify and eliminate them, preventing them from multiplying in our bodies and causing diseases. Without immunity, we may have no resistance to various pathogens, and even slight changes in the environment can make us sick.

When we are injured or sick, the immune system can mobilize various resources within the body to accelerate wound healing and tissue repair, allowing us to recover faster.

Many chronic diseases, such as heart disease, diabetes, cancer, etc., are related to low immunity. Only by maintaining good immunity can we effectively prevent the occurrence of these diseases and maintain physical health.

The strength of immunity is not constant, and it is influenced by many factors, including genetics, environment, and lifestyle. Therefore, we need to improve and maintain our immunity through reasonable diet, appropriate exercise, good sleep habits, and other methods.

The immunity of the human body, like a solid castle, protects us from the invasion of external diseases. However, the solidity of this castle is not constant, and it gradually weakens as time passes.

Professor Wang Yue dan, a professor in the Immunology Department of the Basic Medical School of Peking University, pointed out that the human body's immunity begins to decline from the age of 30, and by the age of 40, the defense power of this immune castle is the weakest.

The reasons behind this are closely related to the pressure of life and work in middle age. In middle age, people shoulder the dual responsibilities of family and society. The busyness of work and the trivia of life make it difficult for them to maintain the healthy lifestyle they had when they were young.

If you find yourself getting sick more easily than usual, or if your illnesses last longer, this may be a clear sign of decreased immunity, which may manifest as frequent colds, flu, sore throat, or other infections.

Persistent fatigue and a sense of weakness may be signs that the immune system is fighting against some underlying diseases or infections. If your fatigue cannot be relieved through rest or normal daily activities, then this may be a signal that needs attention.

Antioxidants are shields for the immune system. Antioxidants, known as shields for the immune system, play a crucial role in maintaining our health. They are like brave soldiers, always ready to fight against the enemies that disrupt our bodily balance - free radicals.

Free radicals are highly active molecules that wage relentless attacks inside our bodies, damaging healthy cells and tissues, and thus triggering various diseases.

Antioxidants, on the other hand, are the important weapons our bodies use to fight against these free radicals. They can neutralize free radicals and prevent them from causing harm to the body, thereby protecting our health.

Our bodies produce a large amount of free radicals every day, which come from our daily lives, such as air pollution, ultraviolet radiation, smoking, drinking, etc. Therefore, we need to constantly consume antioxidants to counter the threats of these free radicals.

Food is the main source of antioxidants. Many fruits and vegetables are rich in antioxidants, such as vitamin C, vitamin E, beta-carotene, etc. In addition, some special plant-based foods, such as green tea, red wine, and chocolate, also contain abundant antioxidants.

We can consume enough antioxidants through a reasonable diet to enhance our immunity and resist the attacks of free radicals.

Probiotics and prebiotics, as partners of the immune system, jointly play an important role inside our bodies. Their interaction provides solid protection for our health.

Prebiotics are special nutrients that cannot be directly absorbed and digested by the human body but can be utilized by probiotics. By consuming prebiotics, we can provide sufficient nutrition for probiotics and promote their growth and reproduction in the intestines.

This way, the number and variety of probiotics become richer, allowing them to better fulfill their roles in maintaining intestinal health, enhancing immunity, and other aspects.

In addition, probiotics can help us resist the invasion of external pathogens by activating the immune system and improving resistance.

Yogurt is undoubtedly a star food for probiotics. Yogurt fermented by lactic acid bacteria not only has a rich and mellow taste, but is also rich in active probiotics. They can help regulate the balance of intestinal flora and promote digestion, safeguarding our health.

In addition, some traditional fermented foods are also good sources of probiotics, such as pickled vegetables, pickled cucumbers, and fermented bean curd. These foods, which have undergone long-term fermentation, not only have unique flavors, but are also rich in probiotics. They can help us improve digestion, enhance immunity, and allow us to enjoy healthy eating while enjoying delicious food.

The immune system, a complex network composed of immune organs, immune cells, and immune active tissues, is the loyal guardian of our body. Like a well-trained army, it is always ready to identify and eliminate any foreign invaders, such as viruses and bacteria.

At the same time, it can also properly handle senescent, damaged, dead, and degenerated self-cells, as well as identify and process mutant cells and virus-infected cells within the body.

In brief, immunity is like the wall of our body, protecting us from the invasion of diseases.

So, does frequent illness mean weak immunity? Doctor: In most cases, frequent illness is indeed a sign of low immunity, which means that compared to ordinary people, those who frequently get sick are more vulnerable to diseases.

However, some people may ask: since frequent illness is not a sign of strong immunity, why do some people who never get colds suddenly suffer from serious illnesses? This is actually because occasional colds can help mobilize immune cells to fight viruses, enabling the immune system to strike more accurately when the virus attacks again, thereby reducing the chance of getting colds again.

For some people with weak immune systems, they may not be able to fight against the "enemy" accurately, so the chance of getting sick naturally increases.

It is worth noting that those who frequently suffer from fever and colds often have poor immune function, which means that their risk of suffering from some major diseases will also increase.

For example, people who frequently have diarrhea or stomach pain are likely to have problems with gastrointestinal function, which increases the risk of developing chronic gastrointestinal diseases.

On the contrary, those who basically do not get sick in life often indicate that they have good immunity and are healthier.

Regarding the relationship between immunity and cancer risk, there is a common saying that people with strong immunity have a very low risk of developing cancer. So, is this statement credible?

Cancer, as a complex disease, is caused by multiple factors, including genetics, environment, and lifestyle. Although immunity plays a certain role in preventing cancer, it is not the only factor.

People with strong immunity are better able to identify and eliminate abnormal cells in the body, thus reducing the risk of cancer. However, this does not mean that they will not develop cancer, as the occurrence of cancer is a multi-factorial and multi-step process, and immunity is only one part of it.

In addition, both excessively strong and weak immunity can have adverse effects on human health. Excessively strong immunity may lead to the body's over-attack on normal cells, triggering autoimmune diseases. Excessively weak immunity may cause the body to be unable to effectively resist the invasion of external pathogens, increasing the risk of developing diseases such as cancer.

Therefore, we cannot simply equate immunity with cancer risk. To prevent cancer, in addition to maintaining good immunity, we also need to pay attention to various factors such as balanced diet, appropriate exercise, and maintaining good living habits.

Sleep is the key to restoring immunity. Long-term lack of sleep can lead to a decline in immunity, so it is important to ensure sufficient sleep time every day. Adults generally need 7-8 hours of sleep. At the same time, maintaining good sleep quality is also important, avoiding excessive excitement and tension before bedtime.

Diet has a significant impact on immunity. We need to ensure sufficient intake of nutrients, including protein, vitamins, and minerals. Consume plenty of fresh vegetables, fruits, whole grains, and high-quality protein, while avoiding excessive intake of greasy, high-sugar, and high-salt foods.

Exercise can improve immunity and enhance physical fitness. We should choose suitable exercise methods, such as walking, jogging, swimming, yoga, etc., and adhere to performing them 3-5 times a week, with each session lasting for more than 30 minutes. During exercise, we should pay attention to moderation and avoid overexertion.

Stress is the natural enemy of immunity, and long-term mental stress can lead to a decline in immunity. It is important to learn to adjust one's mindset, reduce stress, and maintain a pleasant mood. One can relax their mind through meditation, listening to music, communicating with friends, and other methods.
