The eye – the window of the heart
The eyes are the most precious organ of the human body, is the window of the human body and the outside world, people through the eyes to observe, recognize, understand the outside world, about 80% of the brain knowledge and memory are obtained through the eyes.
The eye is not only an important visual organ, but also the focus and main sign of beauty. People's examination of appearance begins with the eyes. A pair of big, bright eyes is essential for everyone, so how to protect the windows of our hearts? What nutrients are essential for eye health?
1. B vitamins, vitamin C and vitamin E
The eye needs the participation of many enzymes and a large supply of nutrients to work. Among them, vitamin B2 is called "beauty vitamin", if it is deficient, the eyes will often be afraid of light, tears, the whites of the eyes are covered with red silk; Vitamin B6, pantothenic acid, etc. can also help the eyes recover from fatigue; Vitamin C and vitamin E have a certain antioxidant effect, they can delay the aging of eye function and prevent the occurrence of various senile eye diseases.
2. Lutein and zeaxanthin
There is a pigmented area at the posterior pole of the retina, which is yellow due to the high concentration of lutein, so it is called "macula".
Lutein and zeaxanthin are the only two carotenoids in the organization that absorb harmful ultraviolet and short-wave light from light while trapping dangerous free radicals, thereby helping the eyes slow down aging, especially preventing age-related macular degeneration. At the same time, they also have a certain preventive effect on cataracts.
3. Vitamin A and carotene
Human eyes are very adjustable, and can quickly adjust their photoreceptor cell response in different light and different colors. An important nutrient responsible for vision in low light and light and dark vision is vitamin A.
If this vitamin is insufficient, the eye's ability to adapt from light to dark will decrease, and it will feel like you can't see clearly at night.
In addition, vitamin A is a nutrient necessary for mucosal differentiation and renewal, and deficiency can lead to dry eyes. The carotene in plant foods can be converted into vitamin A in the body, so it is also a good source of supplementation.
4. Anthocyanins
When the eyes work at high intensity, they need sufficient blood supply, and anthocyanins can increase the blood flow of the fundus microcirculation, accelerate the exchange of substances metabolism and enhance the protective effect on capillaries. This phytochemical also has a strong antioxidant power, which helps prevent fat oxidation and improve vision recovery time.
5. Calcium and zinc
The movement of the eye requires the pull of the muscles, and calcium is closely related to the flexibility of the muscles.
If there is a long-term calcium deficiency in the diet, the muscles are stiff and the elasticity decreases, resulting in inflexible eye movement, poor eye muscle adjustment and recovery ability, and even the elongation of the eye axis leads to deepening of myopia.
Zinc is the active factor of many enzymes and is also an essential nutrient for vision formation, if not enough zinc, it can lead to vision loss and poor vision in low light.
Interestingly, these "eye protection essentials" mentioned above are very rich in sea buckthorn. Take vitamins as an example: after a large number of studies on sea buckthorn by scientific research institutions and medical institutions in many countries around the world, sea buckthorn contains extremely high vitamins, 100g of fresh sea buckthorn juice contains about Vc1000mg, which is 2 to 5 times that of kiwifruit.
Not only that, sea buckthorn is also rich in vitamin A, vitamin B family, vitamin D, vitamin E, vitamin K and other nutrients, which is a real treasure trove of vitamins. Other nutrients beneficial to the eyes such as anthocyanins, luteins, zeaxanthin, trace elements, etc., the content in sea buckthorn is also considerable.
So, so to speak, sea buckthorn is a good helper for eye protection! It is recommended to put 1-2 drops of sea buckthorn seed oil into the eyes every day before going to bed, gently massage the eyes, and the eye problems will be greatly improved after using one stage.
