Neglected Nutrient in Diet Could Be the Solution to Regaining Vision Loss

Volume 1: Issue #3

The outlook was bleak.

Norah Norton faced the prospect of losing a significant portion of her vision. Her deteriorating eyesight led her to resign from her cherished role as an art curator. Driving became impossible. Gardening was no longer feasible. Reading became too strenuous. Her quality of life plummeted.

"I was devastated, and my initial concern was not wanting to burden my two children."

Norah received a diagnosis of age-related macular degeneration (ARMD), a degenerative condition affecting many individuals over 50, resulting in vision loss.

However, Norah was fortunate. She came across an ophthalmologist on the radio who hailed from the Waterford Institute of Technology (WIT) in Ireland, her place of residence. This institute is renowned for its pioneering ARMD research.

The radio specialist mentioned three dietary components that could potentially slow down, halt, and even reverse the condition for numerous individuals.

Norah promptly followed the specialist's recommendations, incorporating the three nutrients into her diet through a supplement. Four years later, her vision has substantially recovered. She has resumed her work, regained the ability to drive, and rediscovered her hobbies.

"I'm back on the right track both professionally and personally," she stated. Keep reading to discover what she used. . .

Affects 15 million Americans & set to grow rapidly

The macula, a small region near the retinal center crucial for sharp central vision, contains a high concentration of light-detecting photoreceptor cells and consumes significant amounts of oxygen. These factors render it susceptible to damage from free radicals.

Free radicals can lead to thinning and breakdown of macular tissue, resulting in distorted vision in the early stages of ARMD manifesting in various ways.

• Straight lines may appear distorted.
• Facial features could seem misshapen.
• Colors may appear dull.
• Glare from lights may be intensified.
• Contrast sensitivity could be compromised.
• Fine details may become indiscernible.

These symptoms may progress until individuals experience complete central vision loss. Approximately 15 million Americans are already affected, a number projected to double in the next decade due to an aging population.

Regrettably, many people take their eyesight for granted.

Professor John Nolan, the lead investigator at WIT, articulates: "People often fail to realize the potential of losing their vision. However, it is a genuine possibility."

Protect your eyes with carotenoids

Fortunately, there are proactive measures individuals can take to preserve macular health as they age.

Four established risk factors for ARMD include age, family history, smoking, and diet.

While age and genetics are beyond control, eliminating smoking and enhancing dietary choices are viable strategies.

Regarding dietary intake. . .

The macula harbors a yellow pigment known as macular pigment (MP), which shields photoreceptors from high-energy blue light, preventing damage and enhancing visibility.

However, MP density diminishes with age, reducing its protective capabilities. Sustaining MP is crucial for optimal macular health.

Among the 50 carotenoids present in food, only three—lutein, zeaxanthin, and meso-zeaxanthin—constitute MP. Lutein and zeaxanthin can be obtained from leafy greens and colorful fruits such as spinach, kale, corn, and kiwi.

Professor Jim Stringham, a lutein expert from the University of Georgia, advises a daily intake of at least 10 mg of lutein to maintain MP and eye health, akin to consuming two large servings of spinach. Notably, most individuals he has examined exhibit lutein deficiency.

Although it is possible to acquire sufficient carotenoids from dietary sources, practical challenges hinder attaining optimal levels.

The most potent protector - meso-zeaxanthin

MP density peaks at the macular center and declines towards the periphery.

Meso-zeaxanthin, situated solely at the center, boasts the highest antioxidant potential among the three carotenoids due to the heightened metabolic activity and susceptibility to free radical damage in this region.

Meso-zeaxanthin is regarded as the primary pigment for safeguarding the macula.

Traditionally, the body was assumed capable of converting sufficient meso-zeaxanthin from lutein. Recent WIT research, however, reveals that individuals with a central MP deficiency lack this conversion enzyme, elevating their risk of ARMD.

While small amounts of meso-zeaxanthin are found in fish skins, it is absent in other natural sources. Therefore, relying on diet alone for meso-zeaxanthin is impractical. WIT researchers observed that supplementing with meso-zeaxanthin restored MP and improved vision in individuals with central deficiencies.

Additional WIT studies demonstrate that supplementing with all three carotenoids yields superior outcomes compared to lutein and zeaxanthin alone.

Professor Nolan emphasizes the importance of supplementation: "Optimizing nutrition is crucial by age 60 to minimize the risk of developing macular degeneration and losing central vision."
