Oral omega-3 Supplementation can prevent Adult Vision Impairment

In the past 10 years, Omega-3 fatty acids have been an emerging topic in the world of health and science. They are attributed to numerous health benefits, especially when it comes to brain and cardiovascular health of an individual. They lower the blood pressure, prevent the blockage of vessels, reduce the levels of bad cholesterol, and alleviate the risks of heart and brain stroke. They’re also reasonably effective against mild memory loss and depression and are also reported to stave off dementia.

Recently, some researchers from Australia have reported significantly reduced levels of eye diseases among healthy, young adults who supplement their diet with omega-3 fatty acids.

Health and wellbeing is a top concern of every individual. Age-related deteriorations like vision impairment, hearing loss, weak bones etc. are very natural. However, some people encounter such hazards before time which can be opposed using health supplements or practicing a healthy diet.

The scientists at the University of Melbourne in Australia have found omega-3 fatty acid supplements to be useful in the prevention of age-related vision impairments, including macular degeneration, glaucoma, and dry eye disease. All of these conditions are said to be the result of insufficient nutrient intake or excessive nutrient loss.

Talking about Glaucoma, researches report, high intraocular pressure (IOP) is a major regulating risk factor for the onset of glaucoma. The Melbourne researchers’ team had evaluated oral omega-3 supplement to serve as a solution to the elevated levels of IOP.

73 female and 32 male test subjects were recruited for conducting the experiments. Seventy-two of the individuals were fed with an oral omega-3 supplement, and the rest of the 33 participants were given an olive oil based pill.

The analysis continued for three months. At the end of the study course, the researchers reported that the group of individuals who were given the omega supplements showed a decrease in the level of IOP by 8 percent.

The researchers had claimed that their study had certain limitations. However, it actually provides the basis for an innovative idea which has to be researched on a wider platform.

Foods rich in Omega-3 fatty acids can also serve the purpose. A recent study had revealed that not only the highly manufactured drugs but a regular intake of nutrients providing the necessary ingredient can also prevent diseases.

Many foods are composed of nutrients that support the well-being of an organism. A study published in 2017 found that avocados can actually improve eye health exceptionally.

Avocado contains Lutein. Lutein is a powerful antioxidant and a phytonutrient attributed to various ocular benefactions. The study claims that avocado consumption increases the level of Lutein inside the body of an organism. Moreover, the increased level of Lutein has been reported to cause macular pigmentation among the test subjects substantially. As sources explain, the macular pigment is a yellow spot which is made up of Lutein and Zeaxanthine i.e. carotenoids in nature. Macular pigment plays a vital role in regulating the function of the macula and is therefore vital to eye health.

Similarly, other foods rich in omega-3 fatty acids, carotenoids, and specifically Lutein are beneficial for the health of the eyes. These foods may include carrots, sweets potatoes, pumpkin, tomatoes, cantaloupe, apricots, goji berries and other foods containing red, orange or yellow pigments. Some green foods, like avocados, broccoli and spinach can also serve the purpose explicitly.

Along with including these healthful ingredients to your diet, some of the following tips must be followed in order to promote the health of your eyes;

  1. Reduce your screen time
  2. Do some light eye exercises
  3. Sleep on right time
  4. Don’t expose your eyes to direct sunlight
  5. Wear glasses when going out in sun
