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:

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.

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.

A new study has found a link between vascular diseases, specifically high blood pressure, diabetes, and increased risk for dementia. Vascular risk factors were higher in both female and Black participants, as well as non-carriers of the APOE ε4 gene, which is linked with an increased risk of Alzheimer’s.1
The statistical results of this cohort study suggest that between 22% and 44% of incident dementia cases by 80 years old were attributed to midlife and late-life vascular risk factors.
What are the connections between caffeine, coffee and eye health? Do the negatives outweigh the positives? This is a tricky question, given the contradictory research on this popular beverage. Coffee is high in antioxidants that have broad health benefits. However, coffee is typically acidic, which can cause stomach symptoms. The caffeine in coffee is a stimulant that increases alertness, but it can also cause energy crashes. Caffeine research has not yet pinpointed the ideal amount of caffeine for better health. According to Traditional Chinese Medicine, coffee can be helpful or harmful, depending on the constitution of the drinker.

The 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.

Did you know that two substances of Asian origin, nattokinase and serrapeptase, have significant health benefits? Scientific studies have revealed some of the reasons why longevity is associated with regular consumption of serrapeptase and nattokinase supplements. Specifically, we will discuss cardiovascular disease, eye issues such as floaters, macular degeneration, and diabetic retinopathy, internal scar tissue from autoimmune disorders, lung disease, sinusitis, neurological disorders, and inflammatory bowel disease.

Retinal scans are proving to be an effective way to detect early signs of diseases like diabetes, multiple sclerosis, and dementia. They can sometimes detect disease before symptoms appear. The best news about retinal scans is that they are painless and non-invasive. You may have looked into machines that scan the retina at your optometrist or eye surgeon’s office. Why are retinal scans helpful for detecting diseases that are not, technically, eye diseases? How is the retina connected to the brain and brain health?

Poor circulation significantly contributes to eye diseases, including macular degeneration, glaucoma, and diabetic retinopathy. Heart disease and diabetes lead to poor circulation. Our eyes and brain require the most oxygen and nutrients, so they need healthy blood circulation. In this article, we will explore the connections between age-related macular degeneration (AMD) and poor circulation. We will also examine the relationship between heart disease and glaucoma. Additionally, we will discuss how diabetes affects circulation and leads to diabetic retinopathy.

Aged black garlic, a culinary staple, is gaining recognition for its unique flavor and remarkable health benefits. Garlic has long been celebrated for its medicinal properties. Aged black garlic is a fermented food with even more potency and health benefits. Recent research has uncovered the benefits of aged black garlic, particularly in relation to the cardiovascular system and the eyes, including glaucoma and diabetic retinopathy. From improving optic nerve blood flow and reducing intraocular pressure to boosting HDL cholesterol levels and mitigating heart disease risks, aged black garlic is a versatile and powerful ally in promoting overall health.
