Here's another reason to get your recommended daily allowance of vitamins and minerals :. to reduce the chances of vision loss in quarantine
Researchers from several universities in the Netherlands, including Erasmus Medical Center in Rotterdam, found that people who got larger quantities of several nutrients, including zinc and omega-3 fatty acids in their diet had a lower risk of developing a condition known as the macular degeneration.
The common condition erodes the retina and causes vision loss in more than 6% of Americans age 40 and older. It is treatable with medication or surgery, but treatment does not reverse the condition. Accounts age-related macular degeneration for half of all cases of blindness in developed countries.

People with a genetic variation called CFH are 11 times more likely to develop macular degeneration than the general population, and those who have another variation called LOC387715S have a 15 times higher risk.
For the new study, the authors studied 2,167 people over 55 who had one of two genes known to contribute to macular degeneration. The researchers surveyed the eating habits of participants and followed for 10 years to follow the vision loss; participants received eye exams every three years.
The researchers found that among those with the variation in the CFH gene, individuals who got more zinc, beta carotene, omega-3 fatty acids or lutein / zeaxanthin in their diet food were less likely to develop macular degeneration than those who received the lowest amounts. in people who consumed the most omega-3 (268 mg daily), the rate was 28 out of every 100
Among people with the variation LOC387715S, only two nutrients , zinc and omega-3, have been associated with a lower risk of vision loss. But in all cases, the authors found that there was no need to eat excessive amounts of nutrients to see a benefit -. Receive per diems of government recommended healthy food was enough
PLUS Whole grains are best, but refined grains are not bad
For women, this means obtain 1.1 g of omega-3 and 8 mg of zinc per day. Men should get 1.6 grams of omega-3 and 11 mg of zinc per day.
Foods that are rich in zinc include oysters, red meat, nuts and beans. Omega-3 fatty acids are abundant in oily fish like salmon, mackerel, sardines, herring and anchovies. Beta-carotene is found in a variety of fruits and vegetables, including carrots, sweet potatoes, squash, spinach, apricots, and green peppers. Foods rich in lutein and zeaxanthin include eggs and green leafy vegetables.
The authors did not investigate how the nutrients in these foods may help prevent macular degeneration, but since they are all highly nutritious food than the typical American does not get enough, it probably would not hurt for your intake of them.
The study was published in Archives of Ophthalmology .
