Dear ,

All week we’ve been exploring how glycation can silently damage the body from the inside out.

And while it’s often associated with diabetes and wrinkles, glycation reaches far beyond your skin or blood sugar.

In fact, some of the most vulnerable tissues to glycation damage are those rich in structural proteins—especially the eyes.

Your lens, cornea, retina, and vitreous humor are all rich in structural proteins like collagen and crystallin, making them prime targets for AGE accumulation.

Over time, these sticky compounds accumulate in the lens, cornea, retina, vitreous, and optic nerve—where they crosslink proteins, stiffen tissues, and impair cellular function. 

This contributes to cataracts, macular degeneration, vitreous degeneration, and optic nerve damage, while also disrupting antioxidant defenses and nutrient delivery within the eye.

👁️ The good news?

Your body is equipped with natural defense systems that help clear harmful AGEs and protect delicate tissues. But when blood sugar runs high or metabolic function declines with age, these systems can become less effective. 

That’s why it’s important to focus on a way of eating that keeps blood sugar stable. Low-glycemic, carbohydrate-restricted diets, including keto and carnivore diet, have been shown to support healthy glucose metabolism and may help reduce the internal formation of AGEs.

But that’s only part of the picture...

To further limit AGE accumulation, it’s also important to reduce exposure to exogenous AGEs, those formed during high-heat cooking methods like grilling, frying, or roasting at high temperatures.

And when it comes to protecting your vision, two nutrients stand out.

Lutein & Zeaxanthin: Nature’s Sight-Saving Duo 

Research published in the Archives of Ophthalmology cites lutein and zeaxanthin as nature’s most potent peeper protectors.

In addition to giving fruits and vegetables (and egg yolks) their yellow hue, lutein and zeaxanthin help ward off blindness by allowing the eyes to filter harmful short-wavelength light, reducing damage to the macula.

In fact, people getting the most lutein and zeaxanthin in their diet had 35 percent less chance of developing age-related macular degeneration (AMD) compared to those getting the least in this study.

And surprisingly, one of the richest sources isn’t an exotic superfood! 

Egg yolks are naturally rich in lutein and zeaxanthin. And thanks to their healthy fat content, they deliver these nutrients in one of the most bioavailable forms your body can use.

You’ll also find these nutrients in leafy greens like spinach, broccoli, zucchini, Brussels sprouts and romaine lettuce. 

But because these nutrients are fat-soluble, it’s important to pair them with the right fats for optimal absorption. 

Choose grass-fed butter, macadamia nut oil, avocado oil, coconut oil, or extra virgin olive oil—and avoid vegetable oils, which can promote oxidative stress and contribute to retinal damage.

There could be a hidden culprit in your daily diet that’s making things worse...
