Reducing sugar intake may prevent myopia

China has one of the highest rates of myopia in the world, which is linked to excessive sugar intake in the diet. Simply put, an increasingly refined high-carbohydrate, low-fat diet leads to higher sugar intake and fewer nutrients, especially vitamin A, selenium, and the essential fatty acid DHA. The result is that the eyes have "excess glycation and insufficient nutrition."
We know that starch is sugar, and sugar can bind collagen proteins together, causing "glycation" and making muscles lose elasticity. When the muscles around the eyes lose elasticity due to glycation, they cannot adjust focus flexibly. When reading up close for a long time, the eye muscles may fixate on near focus and not easily shift to distant focus, making it difficult to see distant objects. In severe cases, the eye's lens itself can be glycated, becoming cloudy and forming cataracts, even leading to blindness.
On the other hand, an increasingly refined high-carbohydrate, low-fat diet leads to a deficiency in eye nutrients such as vitamin A, selenium, and DHA. Vitamin A, also known as retinol, deficiency can cause decreased vision, night blindness, or even total blindness. Vitamin A is fat-soluble, not water-soluble. Therefore, eating animal products is the best way to obtain and absorb vitamin A.
The key to preventing and alleviating myopia is to avoid eye glycation, supplement eye nutrition, and prevent free radical damage. You can achieve this through the Lucas diet nutrition principles: strictly control refined carbohydrates, eat more fish, seafood, meat, offal, eggs, nuts, seeds, dark vegetables, low-sugar fruits, and fungi, especially salmon, oysters, beef liver, carrots, and mushrooms, etc.
