Do you need to eat leaf Huangsu to prevent the changes of yellow spots? This suggestion for non-profit eye health institutions

There are information and advertisements about eye supplements on the Internet, which can be said to be so numerous that it makes people dazzled. Most of them will tell you that you must take supplements to prevent degenerative eye diseases such as "yellow spot disease" and "cataracts", which are related to age. Most of the so-called eye care supplements are related to "Lutein" and "Zeaxanthin".

"Yellow spots" are the center of our vision (video film). "Yellow spot disease" is also called "yellow spot degeneration". It is the main cause of irreversible visual loss. There is one in every five people over 60 years old, with varying degrees of "yellow spot degeneration". There are three factors that can cause "yellow spot degeneration" that can be caused by 3 that are beyond our control: old age, race, and transcendence. The other 5 are the ones we can control: smoke, trans fat, sunlight (blue), high blood pressure, and obesity.

Why is it called "Huang Spot"? Its English is Macula Lutea, and the original Latin meanings of Macula and Lutea are each called "spot" and "yellow".

The reason why "yellow spots" are yellow is because they contain two kinds of yellow pigments. That is, the "leaves" and "corn yellow" mentioned above. These two pigments have the functions of antioxidant and filtering harmful light (blue light), so it is very important for protecting the eyes.

However, they are not made by us themselves, but are derived from food.

Many kinds of vegetables (such as kale, spinach) and fruits (such as mango, cantaloupe) contain "leaves" and "corn yellow".

Therefore, institutions that care about eyes health recommend eating more vegetables and fruits.

Chicken eggs also contain these two nutrients. However, because of the excessive appetite for food and fat, it is impossible to recommend eating more chicken and eggs.

Then, since you can get it from food, why do you still need to spend money to buy supplements?

I think, to answer this question, it is best to listen to it, not profitable, and what is the organization that really cares about our eyes health.

The United States has three such institutions: the National Eye Institute, the American Academy of Ophthalmology, and the American Macular Degeneration Foundation.

Their suggestions are like this:

People without yellow spot degeneration and those with early yellow spot degeneration should eat more vegetables and fruits and avoid risk factors (smoking, trans fat, obesity, etc.).

People with intermediate or advanced yellow spot degeneration need to take supplements (of course, they also need to eat fruits and vegetables and avoid risk factors).

They suggested supplement ingredients are like this (dose daily):

Vitamin C: 500 mg

Vitamin E: 400 International Unit

Piglite (Piglite Oxide): 80 mg

Leafenin: 10 mg

Maize Yellow: 2 mg

Copper (Piglite Oxide): 2 mg

This supplement ingredients are set after two large clinical trials. Almost all supplement brands also have the same ingredients.

However, a study published in 2014 found that 7 of the 11 popular brands were simply insufficient. All 11 brands have misleading publicity.

In short, all three ophthalmic institutions emphasize that don't believe what the ad says that people who are not sick need to take supplements for prevention. As long as you eat more fruits and vegetables and avoid dangerous factors, supplements are unnecessary. They suggest that ophthalmologists can convey this information to the public.
