In this digital age, smartphones have become an indispensable part of our lives. From the first glance we wake up in the morning to the last moment before we fall asleep at night, our eyes are almost always glued to the screen. This habit not only affects our social and sleep quality, but more importantly, it causes great stress on our vision. Eye strain, dryness, and even vision loss can be a consequence of staring at a screen for long periods of time. But don't worry, we're not powerless.
Pork liver: not only delicious but also protects your "bright eyes"
Pork liver, a common and affordable ingredient, has a position to be reckoned with in the health industry. As a rich source of vitamin A and iron, pork liver is an ideal food choice for people who regularly use mobile phones and electronic devices, especially for the maintenance of eye health.
Pork liver is extremely high in vitamin A. Vitamin A is not only an essential nutrient for maintaining normal vision, but it is also essential for the health of the mucous membranes and epidermal cells of the eye. Staring at a phone screen for a long time can cause retinal damage and eye strain, and vitamin A can be effective in alleviating these symptoms. It enhances night vision by helping the eyes adapt to changes in light, thus protecting the eyes from prolonged screen light.
The iron in pig liver is very important for the prevention of anemia. Anemia can cause insufficient blood supply to the eye, which in turn can affect vision. Adequate iron intake helps keep your blood healthy, which ensures that your eyes are adequately supplied with nutrients.
Pork liver also contains other nutrients that are beneficial to the eyes, such as zinc and B vitamins. Zinc is a mineral present in high concentrations in the eye and is essential for vision preservation. B vitamins help reduce eye strain and improve work efficiency.
In the daily diet, moderate intake of pork liver can provide us with these key nutrients. However, it is important to note that due to the fact that pork liver also contains high cholesterol and vitamin A, excessive consumption may cause negative health effects. Therefore, it is recommended to include pork liver as part of the diet rather than as the sole source.
To maximize the nutritional value of pork liver, it is recommended to adopt healthy cooking methods, such as steaming or stewing, to reduce the extra fat intake. Combining fresh vegetables, such as leafy greens and tomatoes, not only adds flavor to the dish, but also provides additional nutrients that work together to protect eye health.
Carrots: Guarding Your "Light of Vision"
Carrots, an everyday ingredient, not only add color to the table, but are also a treasure for eye health. Its secret weapon is β-carotene, a powerful antioxidant that converts into vitamin A in the body. This transformation is essential for maintaining retinal health, especially at night and in low-light environments. Vitamin A deficiency can lead to night blindness, which is why carrots are traditionally known as the "food for night vision."
In the digital age, staring at a phone or computer screen for long periods of time has become the norm, which puts unprecedented strain on the eyes. The blue light emitted by the screen has the potential to damage the eyes and may accelerate the degeneration of the macular area, which is a common problem affecting the vision of middle-aged and elderly people. The β-carotene in carrots can help reduce eye fatigue and dryness by reducing the damage to the retina caused by blue light.
It is not difficult to incorporate carrots into your daily diet. Eating carrot salad raw or made into carrot juice is a great way to get the most nutrients because β-carotene is fat-soluble and can be consumed with oils and fats to improve absorption. At the same time, light cooking such as steaming can release more β-carotene. Whether as part of a main course or as a healthy snack, carrots are ideal for maintaining eye health.
Goji Berry: Ancient tonic, modern eye protector
Goji berries, this small, crimson berry, have occupied an important place in traditional Chinese medicine since ancient times. Not only is it a great tonic, but it is also believed to be especially beneficial for the eyes. But it's worth much more than that. In the light of modern science, goji berries have shown significant effects on eye health, especially for modern people who spend a lot of time in front of mobile phones and computer screens.
Traditional perspective: the medicinal history of goji berries
In traditional Chinese medicine, wolfberry has long been used to nourish the liver and kidneys, and to benefit the eyes and minds. It is recorded in the ancient medical book "Compendium of Materia Medica" that wolfberry can "nourish the heart and calm the nerves, remove heat, and brighten the eyes and intellect." This is not only a cultural heritage, but also a recognition of the unique nutritional value of goji berries.
A Modern Perspective: Scientifically Proven Eye Protection
In recent years, modern scientific research methods have begun to reveal the true value of wolfberry. Studies have shown that goji berries are rich in antioxidants, such as β-carotene, selenium, and zinc, which are particularly effective at protecting the retina. These nutrients can help reduce eye fatigue caused by prolonged use of mobile phones and electronic devices, and may even help prevent age-related eye diseases.
Anti-blue light effect of goji berries
In the digital age, our eyes are often exposed to blue light, which can have a negative impact on vision. Certain ingredients in goji berries have been found to resist the damage of blue light and protect the eyes from the stress that comes with looking at screens for long periods of time. This is especially important for middle-aged and elderly people who use mobile phones regularly.
Recommendations for the daily consumption of goji berries
Despite the numerous benefits of goji berries, they should also be consumed in moderation. Approximately 15 to 30 grams per day is sufficient. It can be eaten dry, soaked in water, boiled porridge, or paired with other ingredients. This natural, simple way makes goji berries an easy superfood to add to your daily diet.
