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

Want to support healthier vision and improve your overall health as you age? One practical place to begin is to eat fewer ultra-processed foods and choose more whole or minimally processed foods. You do not need a perfect diet, nor do you need to eliminate every packaged product. Small, consistent substitutions can improve the quality of your diet while reducing ingredients and processes that promote inflammation, oxidative stress, poor blood sugar regulation, diabetes, heart disease, and cancer.
A diet dominated by ultra-processed foods may raise the risk of serious age-related eye conditions, including macular degeneration, cataracts, and glaucoma. These products may contribute to high blood sugar, inflammation, and oxidative stress that damage delicate cells and blood vessels in the eyes. A diet lacking essential fatty acids and other nutrients may also interfere with healthy tear production and contribute to dry eye. When you choose these foods, you miss out on crucial nutrients. And, many ultra-processed foods are high in calories while providing few useful nutrients. Hence the term “junk food.” 1 2
Ultra-processed foods are industrial formulations made from extracted ingredients and additives rather than intact foods. They often undergo processes such as molding, pre-frying, or chemical modification and may contain flavors, colors, sweeteners, emulsifiers, or other substances that are rarely used in a home kitchen. 3

Healthy cooking can help protect your eyes, brain, heart, and overall wellness. The way you choose, prepare, cook, and store food can affect nutrient levels, toxin exposure, inflammation, blood sugar balance, and long-term disease risk. Simple choices, such as using safer cookware, limiting aluminum exposure, choosing fresh or frozen foods over canned foods, and cooking with healthy oils, can make everyday meals more nourishing.
This article shares practical cooking tips for healthy eating, including how to reduce aluminum exposure, choose safer cookware, prepare vegetables and proteins, support the body’s natural detoxification pathways, and make a nutrient-rich French Peasant Stew. These healthy cooking strategies are especially helpful for people who want to support vision health, reduce oxidative stress, and build better daily habits without making food preparation complicated.

Research on the dangers of artificial sweeteners continues to roll out. A 2026 Tufts University review and meta-analysis compared studies of artificial and low-calorie sweeteners with non-caloric options. 1 The researchers found that artificial sweeteners increased fasting insulin and HbA1c numbers, and tended to reduce insulin sensitivity. Additionally, they pointed to how artificial sweeteners change the gut microbiome as a possible culprit.
Non-nutritive, artificial sweeteners are FDA-approved, low-calorie alternatives to sugar. They can be synthetic or naturally derived and are found in a range of products, from diet soda to protein bars to sugar-free gum. They are also used as coffee sweeteners.
Multiple studies have shown various side effects associated with the use of these sweeteners. These side effects include gastrointestinal symptoms, 2 neurologic (damage) 3 and taste perception changes, 4 allergic reactions, 5 insulin and metabolic effects, 6 and cardiovascular effects. 7

our 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

You’ll often hear that GMO foods are “safe.” But that simple headline skips the part many shoppers care about most: in the U.S., many GMO/bioengineered crops are designed to work with specific herbicides. So the real-world question for consumers isn’t only “Is the genetic change safe?”—it’s also “What farming chemicals and residues tend to come with these GMO/bioengineered crops, and how do I reduce exposure?”.1
This guide breaks down what GMO and bioengineered mean, why herbicide-tolerant GMO/bioengineered crops are controversial, and exactly what to look for on packages and ingredient lists.2

Scientific studies strongly suggest that artificial sweeteners, once thought to be safe alternatives to sugar, are linked to significant health risks. Key findings include increased risks of cardiovascular disease, stroke, type 2 diabetes, metabolic syndrome, cognitive decline, and potential carcinogenicity.1 2 Artificial sweeteners discussed include erythritol, sucralose, and aspartame, which can alter gut microbiota,3 increase inflammation, and cause blood clotting.

A large body of scientific research backs up the claim that astaxanthin is great for your body. As a potent antioxidant, astaxanthin scavenges free radicals that cause cellular damage. This benefits many parts of the body, including your skin, eyes, and brain. What is astaxanthin? Where does it come from? And what does the latest research say about its benefits?
Astaxanthin is a marine xanthophyll carotenoid primarily produced by microalgae like Haematococcus pluvialis. Dietary astaxanthin can be obtained through seafood, including salmon, trout, shrimp, and krill.

The US Department of Health and Human Services (HHS) released its long-awaited update to the nation’s dietary guidelines on January 7, 2026, promising a “historic reset” that puts real, minimally processed food back at the center of American nutrition policy 1. Chronic diseases like heart disease, diabetes, and obesity are high, and these guidelines aim to “Make America Healthy Again.”
On the other hand, the Mediterranean Diet is popular for its proven benefits in reducing the risk of chronic diseases and promoting long-term wellness. It focuses on plant-based meals, healthy fats, and a balanced lifestyle. At Natural Eye Care, we adapted the Mediterranean Diet specifically for people with vision issues and called it the Vision Diet. This diet includes additional recommendations on antioxidant intake, organic foods, and avoiding certain additives and fats 2.
