Caffeine and Dementia Risk

Research linked daily moderate consumption of caffeinated coffee or tea to an 18% lower risk of dementia. ¹ A major JAMA study followed more than 131,000 adults for as long as 43 years, which gives this research weight. The researchers looked at coffee, tea, dementia risk, and cognitive function. They found that people who drank more caffeinated coffee had a lower risk of dementia and were less likely to report subjective cognitive decline. Caffeinated tea showed similar favorable associations, while decaffeinated coffee did not show the same connection.

Glucosamine sulfate is one of the most popular supplements taken for joint support. More than 40 million Americans take this compound daily for stiff joints and pain associated with osteoarthritis. Eight percent of seniors report taking glucosamine, making people ages 60 and up the biggest market for this supplement. What does the research show about its effectiveness and potential side effects? In this article, we discuss these questions, and reveal a 2026 study that links accelerated dementia in glucosamine supplement users who already showed signs of dementia.

Glucosamine Studies

Glucosamine sulfate is primarily studied for its potential to relieve osteoarthritis (OA) symptoms, especially in the knees. Research also looks at its role as a potential cartilage-preserving agent, particularly in relation to osteoarthritis management.

Your nervous system runs on communication. Nerves send signals from the brain and spinal cord out to the rest of the body, and back again. Myelin is the protective, fatty coating wrapped around many nerve fibers. Think of it as insulation around wiring: it helps signals travel faster, more clearly, and with less electrical leakage. ¹

Myelin is also part of a bigger support system. In the central nervous system (the brain and spinal cord), specialized cells called oligodendrocytes help build and maintain myelin. These cells do not just wrap nerves; they also support neurons structurally and metabolically, helping the nervous system meet energy demands over time.

A healthy, nutrient-rich diet supports long-term brain and eye health and may help lower the risk of serious conditions like Alzheimer’s disease and other dementias, as well as vision disorders such as macular degeneration and glaucoma.

One eating pattern often highlighted for these benefits is the Mediterranean-style diet. Research links consistent adherence to this approach with lower overall mortality, reduced deaths from cardiovascular disease and cancer, and a decreased likelihood of developing chronic, degenerative illnesses.¹

As we get older, it’s common to notice changes in memory, focus, and mental sharpness. Researchers often discuss these changes in relation to neurogenesis—the ongoing creation of new brain cells—which tends to slow down with age. Because neurogenesis supports the brain’s ability to adapt and maintain itself (often called plasticity), a decline may be associated with reduced cognitive performance over time.

Age-related factors such as oxidative stress and inflammation are frequently discussed as reasons neurogenesis may slow down. At the same time, healthy dietary patterns and lifestyle habits are often studied for their potential to support brain health and the processes involved in maintaining brain tissue.

Coronary 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.

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.

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.

Allergies 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

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.
