Can the Mediterranean Diet Lower Dementia Risk and Support Eye Health?

Mediterranean DietThe Mediterranean Diet and dementia have an encouraging research connection. In a large observational study, people whose eating habits most closely followed a Mediterranean-style pattern had a lower risk of developing dementia. What can we conclude from this study? How can your eating habits help prevent disease in the future? Keep reading for details about the study and practical tips for better nutrition.

What the Mediterranean Diet Study Found

Researchers followed 60,298 adults in the United Kingdom for an average of 9.1 years. The participants were ages 40 to 69 when they entered the study. Researchers compared their diets with two Mediterranean diet scoring systems and recorded new cases of dementia.

One system was the Mediterranean Diet Adherence Screener, commonly shortened to MEDAS. It gives points for habits that fit a Mediterranean-style pattern, such as eating vegetables, fruit, legumes, fish, and olive oil. A higher score means closer adherence to the pattern.

Can a Multivitamin Support Vision and Healthy Aging?

man taking a multivitaminCan one daily multivitamin help you remain active and independent as you grow older? New research offers a cautiously encouraging answer. In a large randomized study, adults age 60 and older who took a daily multivitamin for three years reported slightly better functional health than those who took a placebo. Functional health includes how well you manage everyday activities and how much symptoms interfere with daily life.

The study included more than 16,000 participants from the COSMOS trial. The differences were modest and were measured with questionnaires rather than objective physical tests. The findings were presented at the NUTRITION 2026 conference but have not yet been published in a peer-reviewed journal. They are interesting, but they do not prove that a multivitamin prevents disability or treats fatigue, shortness of breath, or swelling in the feet. New or worsening symptoms like these require medical evaluation. 1

A multivitamin can help fill nutritional gaps, especially when appetite, food choices, medications, or changes in digestion make it difficult to obtain enough nutrients. It cannot replace a varied diet, exercise, sleep, prescribed treatment, or regular eye care. Evidence also does not show that routine multivitamin use prevents every chronic disease. The most sensible goal is nutritional support, not a promise of disease prevention. 2

Are Sugary Drinks Bad for Your Eyes and Overall Health?

sugary drinks including coffee, energy drinks and sodaSugary drinks and eye health may seem unrelated, but what you sip each day can affect much more than your thirst. A new long-term study found that people who consumed at least one sugar-sweetened drink daily had more than twice the risk of developing stomach cancer compared with people who rarely drank them. The study does not prove that sugary drinks caused the cancer, but the size of the association deserves attention.

Sodapop is not the only drink worth examining. Fruit punches, lemonades, sports drinks, energy drinks, sweetened coffees, and some electrolyte beverages can contain surprising amounts of added sugar. Cutting back does not mean that you should automatically switch to diet beverages containing artificial sweeteners. There are better everyday choices, including water, lemon water, coffee, tea, green tea, and drinks lightly sweetened with stevia.

How much sugar is hiding in your favorite drink? When do you actually need electrolytes? Are diet drinks a healthy substitute? This article examines the new stomach cancer research, the relationship between sugary drinks and eye health, the proper use of electrolyte beverages, and practical ways to reduce sugar without giving up every occasional treat.

What Counts as a Sugary Drink?

A sugar-sweetened beverage is any drink containing sugar that was added during manufacturing or preparation. Common examples include:

How Does the Body Detoxify? Eyes, Brain, and Whole Body

lymph nodes
The Lymphatic System – Upper Body

Detoxification is essential for maintaining health. It is the body’s natural process of identifying, breaking down, and eliminating potentially harmful substances. The liver does most of this work, while the kidneys, digestive system, lungs, skin, and lymphatic system help remove waste through urine, stool, breath, and sweat. The body continuously detoxifies itself; it does not require special cleanses or extreme diets to perform these essential functions. Several mechanisms in the body accomplish this work.

Two of the most important are the glymphatic and lymphatic systems.

The Glymphatic System

The glymphatic system is the brain’s waste-clearance pathway. It relies on glial cells and cerebrospinal fluid to remove metabolic waste, especially during deep sleep.

Can Macular Degeneration Cause Visual Hallucinations? Charles Bonnet Syndrome (CBS)

Artist’s interpretation of a visual hallucinationEye conditions such as macular degeneration can sometimes lead to visual hallucinations. A visual hallucination means seeing something that is not really there.

The eyes send visual signals to the brain, and the brain interprets them. When vision loss reduces the amount of information reaching the brain, the brain may fill in the missing visual details. This can cause a person to see grid patterns, people, lines, shapes, or other images that are not actually in front of them.

This is known as Charles Bonnet syndrome (CBS). It is linked to vision loss and does not mean that a person is losing touch with reality.

Which eye conditions can cause visual hallucinations? How can you identify and manage them? Is it possible to prevent these eye conditions in the first place? Can nutrition and supplements help?

Vitamin C for Brain Aging and Vision Health

Foods rich in vitamin C, including blueberries, cabbage, citrus fruits, strawberries and broccoli.
Foods rich in vitamin C, including blueberries, cabbage, citrus fruits, strawberries and broccoli.

Vitamin C is best known for immune support, but its role in healthy aging is broader than that. Ascorbic acid, the chemical name for Vitamin C, helps the body make collagen, supports blood vessel integrity, assists wound healing, improves the absorption of iron from plant foods, and acts as an antioxidant. These functions matter throughout the body, including in the brain and eyes.

A recent large study of older adults adds another reason to pay attention to vitamin C status. Researchers found that lower plasma vitamin C levels were associated with lower gray matter volume and weaker connectivity in a major brain network involved in memory, attention, and self-reflection. The study does not prove that vitamin C prevents brain shrinkage or cognitive decline. However, it does suggest that healthy vitamin C levels may be one marker of better brain aging. 1

Could NMN Be Key to Healthy Aging?

senior on a scooterCould NMN help the body age more successfully? NMN, or nicotinamide mononucleotide, is a naturally occurring compound that helps the body produce NAD+, a vital substance found in every living cell. NAD+ plays an important role in cellular energy, DNA repair, mitochondrial function, inflammation control, and other processes that help the body stay resilient over time. However, NAD+ does not remain steady throughout life. One observational study in humans found that NAD+ levels may drop by about 50% by age 50.

For older adults, this decline may be important. Lower NAD+ levels have been associated with metabolic dysfunction, inflammation, reduced mitochondrial performance, and other changes tied to aging and chronic disease risk. Since NMN helps the body make NAD+, researchers are studying whether NMN supplementation may help restore some of this lost cellular support. NMN has recently entered the supplement market. Early research suggests that NMN may benefit several areas of aging health, including energy metabolism, insulin function, brain and nerve health, cardiovascular support, muscle function, inflammation balance, and eye health.

Can N-Acetyl-Cysteine Support Cataracts, Retinitis Pigmentosa, Dry Eye & Macular Degeneration?

Broccoli soup is high in N-Acetyl-Cysteine.N-Acetyl-Cysteine is an amino acid that has been researched heavily for its antioxidant and anti-inflammatory properties. NAC is primarily a building block for glutathione. Key clinical studies explore its role in respiratory health, vision support, liver function, aging, and anti-inflammatory properties.

As an antioxidant, NAC helps protect healthy cells by neutralizing free radicals before they can cause harm. It supports the body’s supply of cysteine, a key building block of glutathione, one of the body’s most important internal antioxidants. By helping restore glutathione levels, NAC strengthens the cell’s antioxidant defenses and helps clear reactive oxygen species, or ROS. NAC also has anti-inflammatory effects. In the early stages of immune activation, it may help reduce the release of cytokines, which are chemical messengers involved in inflammation. 1

Can the Nrf2 Antioxidant Help with Eye Diseases? Macular Degeneration, Glaucoma, Cataracts & Diabetic Retinopathy

Nrf2 can be increased by eating these cruciferous vegetablesOxidative stress may be at the root of many eye diseases. The body depends on a careful balance between oxidants and antioxidants. When that balance is disrupted, delicate tissues in the eye can be damaged. In this article, we will focus on an important antioxidant defense system called the Keap1-Nrf2-ARE pathway, abbreviated as NRF2. We will also look at how this system may relate to major eye diseases, including age-related macular degeneration, cataracts, diabetic retinopathy, and glaucoma—conditions that together account for many cases of vision loss and blindness worldwide.

Oxidative Stress and the Keap 1-Nrf2-ARE Pathways

Free radicals, such as reactive oxygen species (ROS), are oxidants produced as by-products of aerobic metabolism. In addition to the natural metabolic production of ROS, environmental sources such as light, smoking, and exposure to or intake of heavy metals also contribute to increased ROS burden. 1

Vitamin B12 Health Benefits for Vision, Brain and the Whole Body

Vitamin B12 foodsVitamin B12 is a water-soluble vitamin your body needs for DNA synthesis, red blood cell formation, and healthy nervous system function. When vitamin B12 levels are low, people can develop anemia and experience fatigue and weakness. Therefore, maintaining adequate B12 levels is important for day-to-day energy and overall health. However, B12 can be low even in people who eat Vitamin B12-rich meat and dairy products. Vitamin B12 cannot be produced in the body, so it must be obtained from food or supplements.1

Newer research suggests vitamin B12 (cobalamin) status may influence more than nerve function alone. Findings highlighted in 2026 point to a relationship between vitamin B12 and skeletal muscle mitochondrial function (the cell’s energy-producing machinery), which may contribute to metabolic resilience and aspects of healthy aging.2 In practical terms, maintaining adequate B12 may help support muscle function and strength over time, which can matter for mobility and injury risk as we age.
