How the Eye and Brain Handles Removal of Natural Waste

eye cleanEye conditions such as age-related macular degeneration, cataracts, glaucoma, and diabetic retinopathy usually do not have a single cause. Instead, they arise from a mix of influences, including genetics, environment, age, diet and nutrition, and oxidative stress. Among these, oxidative stress is especially important because it directly affects a vital cellular process called autophagy.

Autophagy is the body’s built-in “cellular housekeeping” or recycling system. It allows cells in the eyes and brain to break down and reuse worn-out components, including damaged mitochondria and large, clumped proteins.[1. Kulkami VV, Maday S. Compartment-specific dynamics and functions of autophagy in neurons. Dev Neurobiol. 2018;78(4):298-310. doi:10.1002/dneu.22524] When autophagy is working properly, it helps maintain healthy cell function. But when this process is disturbed, cellular waste can build up, organelles are not renewed as they should be, and the normal physiology of the eye can begin to break down.

Brain Health and Nutrition

Family sharing a meal. Nutrition is crucial for brain healthThe brain and eyes are intimately connected, and the nutrients essential for eye health are the same as for brain health. A retinal scan can detect the early onset of Alzheimer’s Disease, Parkinson’s Disease, and Multiple Sclerosis before symptoms appear.

Numerous studies have shown that dietary factors help prevent brain and eye disease. They have a critical effect on neuronal function and synaptic plasticity. Recent findings have shed light on key processes through which nutrition influences brain health and cognitive performance. Alongside lifestyle factors like physical activity, what we eat has played a significant part in the development of our mental abilities and the evolution of the human brain.

Essential Nutrients for Eye Health: Evidence-Based Guide to Vitamins, Antioxidants, and Supplements

senior takes vitamins and nutrients for eyesProtecting your vision doesn’t have to be complicated or costly. Decades of peer‑reviewed research show that specific nutrients—especially antioxidants, carotenoids, and omega‑3 fatty acids—can help maintain healthy eyes and reduce the risk of common conditions like cataracts, age‑related macular degeneration (AMD), glaucoma, and diabetic retinopathy. While a colorful, nutrient‑dense diet is foundational, therapeutic levels are often difficult to reach through food alone. This guide summarizes key nutrients, food sources, and targeted supplements, drawing on nearly 25 years of research curation at Natural Eye Care and over 45 years of clinical experience by Dr. Marc Grossman.

Caffeine, Coffee and Eye Health

cups of cappuccino coffeeWhat are the connections between caffeine, coffee and eye health? Do the negatives outweigh the positives? This is a tricky question, given the contradictory research on this popular beverage. Coffee is high in antioxidants that have broad health benefits. However, coffee is typically acidic, which can cause stomach symptoms. The caffeine in coffee is a stimulant that increases alertness, but it can also cause energy crashes. Caffeine research has not yet pinpointed the ideal amount of caffeine for better health. According to Traditional Chinese Medicine, coffee can be helpful or harmful, depending on the constitution of the drinker. Continue reading “Caffeine, Coffee and Eye Health”

Cardiovascular Disease and Eye Health

heart affects eye diseaseThe link between cardiovascular disease and eye health may not be obvious. However, the eyes are made from nutrients. A large body of research shows how important nutrition is for eye health. Maintaining healthy vision depends on whether the eyes and visual system are properly nourished. Cardiovascular disease, including high blood pressure and atherosclerosis, can affect the flow of essential nutrients and oxygen to the eyes. Poor circulation to the eyes can cause damage to the retina’s tiny blood vessels, with potentially sight-threatening consequences. Cardiovascular disease can often be identified through retinal scans well before the disease is detectable through traditional tests. Continue reading “Cardiovascular Disease and Eye Health”

Used for centuries in traditional medicine, these powerful plants are now backed by modern research. Whether you add them to your meals or take them as supplements, the right herbs can play a key role in maintaining healthy eyes and aging well.

In this article, discover some of the most effective herbs for vision and wellness, along with general supplement dosage guidelines. Continue reading “Spices and Herbs for Vision Health”

Blue Light and Macular Degeneration (AMD) Risk

blue light from too much screen time can harm the eyes including macular degenerationWe are exposed to blue light daily when we over-use computers, smartphones, tablets, and televisions. We also get blue light from the sun, and LED and fluorescent lights The risks associated with blue-light exposure increase with the duration of exposure. Therefore, take steps to keep your eyes safer. We will explain research on blue light and macular degeneration, and provide tips for reducing blue light exposure.

Green Tea Benefits for Seniors – Antioxidants for the Eyes, Brain, and Body

woman drinking green teaOxidative stress happens everywhere in the body and can create havoc over time. Many eye and brain diseases are triggered or exacerbated by oxidative stress. The body counteracts this stress by producing antioxidants. However, you must also ingest additional antioxidants through healthy food, drinks, and supplements. Green tea, rich in antioxidants, offers protective benefits for eye health by combating oxidative damage.[1. Merin, S. (1991). Inherited cataracts. In Merin S. editor. Inherited Eye Diseases, (pp. 86-120), New York: Mercel Dekker.] At pennies per cup, this convenient and tasty beverage has been studied for its special antioxidant properties. What are the green tea benefits for seniors? Read on to find out. Continue reading “Green Tea Benefits for Seniors – Antioxidants for the Eyes, Brain, and Body”

Diabetic Retinopathy, Sugar Balance and Retinal Support

Diabetic Retinopathy, Sugar Balance and Retinal SupportDiabetic retinopathy is a leading cause of blindness among adults. Poor blood sugar balance can damage nerves, so nerve support is crucial for people with diabetes. Diabetic retinopathy is a serious eye condition stemming primarily from imbalances in blood sugar levels. When blood sugar is not properly managed, the body’s delicate nerve tissues, including the retina, can be injured.

At Natural Eye Care, we have examined the research on nutrients that help protect the eye, including the retina and blood flow to the eye. Research has identified oxidative stress and inflammation as key contributors to the onset and development of numerous eye conditions.[1.Levkovitch-Verbin, H. (2015). Retinal ganglion cell apoptotic pathway in glaucoma: Initiating and downstream mechanisms. Prog. Brain Res, 220:37–57.] [2.Kowluru, R.A., Mishra, M. (2015). Oxidative stress, mitochondrial damage and diabetic retinopathy. Biochem. Biophys. Acta. 1852:2474–2483.] [3.Dib, B., Lin, H., Maidana, D.E., Tian, B., Miller, J.B., et al. (2015). Mitochondrial DNA has a pro-inflammatory role in AMD. Biochem Biophys Acta, 1853:2897–2906.] These conditions include macular degeneration, glaucoma, cataracts, macular edema, and diabetic retinopathy. Without intervention, these eye diseases can result in a gradual decline in vision, potentially leading to blindness. Studies suggest that incorporating specific antioxidant and anti-inflammatory nutrients may be beneficial in preventing and managing these eye disorders.[4.Rhone, M., Basu, A. (2008). Phytochemicals and age-related eye diseases. Nutr Rev, 66:465–472.]
