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.

Retinal Cells Rewire to Preserve Vision in Retinitis Pigmentosa

Retina cross-section diagram showing retinal cells - rods and cones - that have been found to rewire themselves. Retinitis Pigmentosa is a progressive eye disease that has long been associated with gradual vision loss and limited treatment options. Affecting about one in every 4,000 people, Retinitis Pigmentosa (RP) is marked by the degeneration of the retina’s photoreceptor cells—first the rods, which are responsible for night vision, and then the cones, which enable us to see in daylight and color. While the genetic complexity and slow progression of RP have posed challenges for patients and researchers alike, recent discoveries are offering new hope. Exciting new research reveals that the retina may have an unexpected ability to adapt: certain retinal cells can rewire themselves in response to degeneration, potentially helping to preserve vision even as the disease advances.

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”

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.]

Eating Habits Can Impair Circulation, Increasing the Risk of Glaucoma, Retinal Vascular Occlusions, Dry Eyes, Macular Degeneration

Circulation and Eye DiseasesWe might not connect our eating habits to eye disease, but poor nutrition impairs circulation. Reduced circulation can contribute to eye diseases, including cataracts, glaucoma, retinal vascular occlusions, ischemic optic neuropathy (ION), dry eyes, macular degeneration, and diabetic retinopathy. Instead of being a “victim” of eye diseases in your senior years, you can take charge of your health today!

At Natural Eye Care, we believe that the visual system uses approximately 25% of the nutrients we take into the body. Only the brain needs more. Therefore, a nutrient-rich diet helps keep your eyes healthy. Anything that impairs the free flow of blood, oxygen, and nutrients can significantly increase the risk of eye disease. Over time, you could experience vision loss, making you less independent in your senior years.

February: Macular Degeneration Awareness Month

February- Macular Degeneration Awareness MonthThis month, we’re focusing on understanding macular degeneration and the importance of early detection. We will explore natural approaches to manage this eye disease and support healthy vision.

Macular Degeneration is a leading cause of vision loss, primarily affecting central vision, and can lead to blindness if not properly managed. The macula is a yellowish spot at the center of the retina, where vision is sharpest. While genetics can play a role, macular degeneration often appears in those over 50 due to essential nutrients not reaching the eyes, particularly the retina. Factors like a sedentary lifestyle, poor diet, reduced nutrient absorption, certain medication side-effects, and health issues such as poor circulation and chronic inflammation can contribute to this condition.

Food Combining Tips for Better Health

food combination better healthNot all foods play well together. Meat and Potatoes. Surf and Turf. Chicken with Rice. Sounds yummy, right? However, proponents of food-combining diets would not combine protein with carbs, and or mix different types of proteins. Food combining advocates believe that eating certain types of food in the same meal can lead to disease, toxin buildup, and digestive issues. They also believe that proper combinations can help relieve these problems.

Food-combining principles first appeared in the Ayurvedic medicine of ancient India, but they became more widely popularized in the mid-1800s under the term “trophology,” or “the science of food combining.”
The principles of food combining were revived in the early 1900s by the Hay diet. Continue reading “Food Combining Tips for Better Health”

Cataracts and Antioxidants

cataract needs antioxidantsCataracts are a condition where the lens of the eye becomes cloudy. They are common among seniors. Symptoms include:

  • cloudy, blurry, foggy, or filmy vision
  • difficulty seeing at night, especially when driving
  • bright sunlight, headlights, and lights may cause a glare or halo
  • colors may appear faded, muted, or yellowed

Cataracts in seniors are often caused by a lifetime of exposure to free radicals. Long-term exposure to sunlight accelerates, which is called glycation, which is the binding of sugar and protein molecules. Over time, glycation breaks down the structure of the lens.
