Ophthalmologists are adamant that a healthy diet can prevent the development of blindness in old age. Improper nutrition, lack of vitamins and minerals, zinc, lutein can provoke macular degeneration in adulthood and to irreversible vision loss.
The chronic pathological condition is characterized by progressive deterioration of central vision, as often the peripheral remains unaffected. The pathological process develops in the area of the retina responsible for the central, clearest and most contrasting color vision (macula).
As a result, it is difficult to read, clearly focus on objects, face recognition. Gradually there is blurring and blurring of vision, which greatly complicates a person's daily life and worsens his quality of life.
Maintaining good eyesight and healthy eyes is directly related to a balanced diet. Age-related macular degeneration is the most common cause of vision loss in people over 65 years of age. The results of an international scientific study show that over the next 5 years, the number of people suffering from the disease may increase many times over due to the way of life in modern society and especially the excessive consumption of fast food.
The menu in fast food restaurants is extremely high in calories and saturated with salt, saturated fats and carbohydrates. A study shows that just one serving of fried chicken with vegetables contains 1,300 calories, 3,200 milligrams of sodium and 11 grams of saturated fat.
According to nutritionists, all restaurants should reduce calories and salt in their menu, and people should realize that this type of food is extremely unhealthy, especially if consumed daily and in large quantities.
An adult with an active lifestyle needs an average of about 2,000 calories a day and 2,300 milligrams of salt, which is the equivalent of a teaspoon of salt.
In some cases, fast food restaurants are the worst choice for health, according to experts, because their food has the highest content of saturated fat, which increases the risk of heart disease.
In addition to the irreparable damage it does to the macula, fast food has a detrimental effect on waist circumference and blood pressure - high salt levels contribute to the development of hypertension.
Even vegetables in fast food restaurants can be dangerous to health - a serving of fried vegetables contain 900 calories and 2200 milligrams of salt.
Doctors say that a healthy diet, including regular consumption of fresh cabbage, spinach, broccoli, nuts, Brussels sprouts, corn, etc. can save millions of people from blindness. Conversely, unhealthy eating, for example, in fast food restaurants and salt-rich foods, can lead to age-related macular degeneration affecting central vision.
Luteinate and zeaxanthin are carotenoids responsible for the density of the pigment in the macula. They are important in eye protection. Research has shown that the two components play the role of "inner glasses" as they "filter" blue light and protect the eye from the harmful effects of free radicals. These carotenoids are the main elements in the protective system of the eye.
On average, every European eats only one-eighth or one-sixth of the essential carotenoids. Statistics show that the consumption of healthy foods decreases with each passing year at the expense of fast food. Therefore, it is important to increase to three or even four times the consumption of vegetables containing lutein and zeaxanthin, such as spinach, broccoli, peas, Brussels sprouts, nuts, egg yolk and corn.
In addition, with age, the natural protection of the eye weakens and needs even more protection. To ensure the delivery of the required dose of carotenoids, it is advisable to take multivitamins, minerals and dietary supplements enriched with lutein.
