In June 2021, a female student in her 20s in Sichuan with myopia as high as 1500 degrees was diagnosed by an ophthalmologistThere is a correlation between the reason for her myopia progression and her excessive sweets
Is this news credible? Does eating sugar really lead to myopia progression?
A recent article published in the journal Cell Metabolism, titled "Augmentation of Scleral Glycolysis Promotes Myopia through Histone Lactylation", was found through guinea pig mouse experimentsA diet high in sugar can induce myopia in guinea pigs. It has been demonstrated that a high-sugar diet activates the signaling axis of "scleral glycolysis-lactate-histone lactation" and induces myopia.
Prior to the publication of this **, scholars generally believed that:Excessive sweets intake will lead to a decrease in calcium in the blood, which will reduce the toughness of the sclera, resulting in a longer eye axis and a deepening of myopia. Although there is no conclusive evidence that a high-sugar diet can aggravate myopia, limiting sugar intake is still beneficial to the body and avoids obesity, glycation, and even diabetes, which can lead to eye lesions.
In general,The daily sugar intake of children, adolescents and adult women should be controlled within 25 grams; For adult males, it should be controlled within 36 grams。It is best to consume no more than 50 grams of sugar per day.
And what are the diets in life that are rich in sugar and should be reduced?
In addition to the high-sugar desserts and candies we know, there are also some foods that secretly hide "** sugar" For example, various types of beverages, a 500ml can of cola contains about 50 grams of sugar, and the sugar content of many fruit juices, lactic acid drinks, and canned teas on the market is far higher than you think. For example, Western-style bread or Chinese-style pastry should not be underestimated in sugar.
Therefore, it is recommended that everyone drink less beverages, cook dishes or drinks without adding sugar, and eat less bread, biscuits and other sugary pastries. When buying food in supermarkets, you should also pay attention to the nutritional content to see if the sugar content exceeds the standard.
