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.

What Are Ultra-Processed Foods? Effect on Vision and Health

ultra-processed food vs natural foodUltra-processed foods are industrial formulations that undergo extensive processing and typically contain multiple ingredients not usually found in home cooking. Typically, these foods are lower in nutrients and fiber and higher in sugar, fat, and salt compared to unprocessed or minimally processed foods. Ultra-processed foods include soda, packaged cookies, chips, frozen meals, flavored nuts, flavored yogurt, hot dogs, distilled alcoholic beverages, and fast foods. Even many packaged breads, including those high in nutritious whole grains, qualify as ultra-processed because of the additives and preservatives they contain.

Can Atherosclerosis Harm Me? Can Nutrition and Exercise Help?

Atherosclerosis can be staved off with regular exerciseCoronary artery disease stands as the leading form of heart disease in the United States, impacting more than 20 million people. Among atherosclerosis’s most serious risks are heart attacks and strokes, both of which can have life-altering consequences. Fortunately, there are powerful steps you can take to protect your heart health. Building a balanced diet, staying active, and using carefully chosen supplements all play an important role in preventing and managing atherosclerosis. In this article, we will discuss how atherosclerosis happens, its effects on the body, and nutrients that support heart health. We also review basic lifestyle choices, such as exercise and remaining smoke-free, that can add years to your life. Continue reading “Can Atherosclerosis Harm Me? Can Nutrition and Exercise Help?”

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.

Eye Brain Connection: The 5 Steps

The Occipital Lobe Interprets Signals From the Eyes

One important concept for maintaining eye health is understanding the eye-brain connection. This pathway starts with light entering the eye and ends when your brain makes sense of the visual world around you. Disruption or damage at any point in the pathway distorts your perception. Therefore, maintaining the health of each part of the eye-brain connection pathway ensures accurate perception. Your vision accounts for around 80% of your perceptions, learning, and thinking. Maintaining your vision as you age improves your quality of life. Consider how your ability to drive, watch television, read, prepare food, walk in nature, shop, and recognize friends and loved ones enables you to live independently and passionately. At Natural Eye Care, we want you to have the best chance at maintaining healthy vision throughout your whole life. Continue reading “Eye Brain Connection: The 5 Steps”

Food Allergies, Intolerances, and Sensitivities Linked to Vision Problems

Food allergy reaction to garlicAllergies to food can cause eye symptoms, but food allergies can also lead to vision problems. Grouped with food allergies are food intolerances and food sensitivities. While food allergies are an immune system reaction, intolerances and sensitivities are related to the digestive system. In this article, we discuss how individuals with these food issues need to protect their eyes from harm.

The Differences Between Food Allergies, Sensitivities, and Intolerances

Food allergies occur when the immune system produces an IgE-mediated response to specific proteins found in certain foods. In contrast, food intolerances and sensitivities are typically related to the digestive system’s inability to properly break down or process particular foods, rather than an immune reaction. Continue reading “Food Allergies, Intolerances, and Sensitivities Linked to Vision Problems”

9 Healthy Lifestyle Habits for the Eyes, Brain and Body

healthy lifestyle - diet, hydration, sleep, exercise The brain and visual system rely on a significant portion of the nutrients you consume to maintain optimal health and function. Supporting the connections between the body, mind, and eyes is key to promoting healthy vision, preserving brain health, and reducing the risk of age-related eye and brain diseases. This includes macular degeneration, glaucoma, and cataracts, plus dementia and Parkinson’s Disease.

Many of these conditions stem from a lack of essential nutrients reaching the eyes and brain, leaving them deprived of what they need to thrive. Other factors, such as autoimmune diseases, cardiovascular issues, medications, chronic stress, a sedentary lifestyle, poor diet, inadequate sleep, and both genetic and epigenetic influences, can also play a role.

Healthy Cells Mean a Healthy Body: Mitochondria Maintenance

mitochondriaKeeping our cells healthy is key to staying well and helping to prevent disease. Your 30 trillion cells each contain mitochondria, the cell’s tiny “battery” and energy source. The main cause of death worldwide is non-communicable diseases such as heart disease, strokes, diabetes, cancer, chronic lung diseases, and brain diseases, including Alzheimer’s disease and dementia. Anything you do to keep your mitochondria healthy can mitigate these diseases, potentially extending life and increasing the quality of life. We have talked about how mitochondria work in some of our previous articles. In this article, we will discuss the origins of mitochondria, lifestyle considerations, and symptoms of mitochondria disease. Also, we include a long list of foods, supplements and nutrients that support mitochondrial functioning.

Visual Detox – A Whole-Body Connection

visual detoxVisual detox refers to purifying the eyes of debris, toxins, and the effects of bad visual habits. Debris build-up can affect vision health and contribute to the onset of eye disease. These diseases can include eye irritation, effects on lacrimation related to dry eyes, glaucoma, and macular degeneration (AMD). Focusing too much on close-up computer screens leads to computer eye strain symptoms and reduces the free flow of energy to the eyes. As the eyes’ health is directly connected to whole-body well-being, we must look at detoxification from a whole-body perspective.

Other symptoms of toxin build-up can include ocular burning, watering, pain, and photophobia [1. Dwivedi et al., 1985], conjunctivitis and corneal opacity.[2. Maskati, 1986]

Whole-body toxicity symptoms can include:  Continue reading “Visual Detox – A Whole-Body Connection”
