11 Brain-Boosting Foods for Seniors

brain foodsBrain health is especially important in seniors. Seniors are susceptible to dementia, Alzheimer’s disease, memory problems, and cognitive decline. Which foods boost brain power the most? At Natural Eye Care, we have picked eleven common foods that have brain-saving properties. Scientists have been studying the nutrients in foods for decades. They have isolated specific nutrients that cross the blood-brain barrier. These types of nutrients get direct access to the brain and even the retina. The retina is made from neural tissue. Researchers find that many of the nutrients helpful for the brain also stave off eye diseases such as macular degeneration and glaucoma.

Try adding some of these foods to your regular diet. Seniors need fewer calories than younger folks. Therefore, replace “junk food” like cookies, candy, and chips with these brain-boosters. Continue reading “11 Brain-Boosting Foods for Seniors”

Blue Light Harms Fruit Fly Eyes and Brains

fruit fly eye blue lightFindings from a recent study suggest that blue light, the same light emitted from smartphones and fluorescent light bulbs, causes brain damage and premature aging in fruit flies.

Why would research on fruit flies be important for human brains?  Surprisingly, many of the genes of fruit flies are the same as the genes in humans, and studies on fruit flies often reveal information valuable for human health. Fruit flies’ life cycle is short so scientists can see aging patterns.

As published in the journal Aging and Mechanisms of Disease, researchers at Oregon State University conducted an experiment where they subjected adult fruit flies to blue light. The targeted group of adult flies was exposed to twelve hours of blue light, followed by twelve hours of darkness. They then compared these flies to the control group. Those flies were kept in total darkness for twenty-four hours or bathed in light where blue wavelengths were blocked. Continue reading “Blue Light Harms Fruit Fly Eyes and Brains”

Vitamin D and the Eye: Uveitis, Macular Degeneration, and Dry Eye

vitamin d moleculeLack of Vitamin D has been associated with eye diseases like uveitis, macular degeneration, and dry eye. Vitamin D deficiency is also linked to cancer, immune disorders, heart disease, high blood pressure, osteoporosis, bone pain, depression, asthma, multiple sclerosis, and even dementia. Shockingly, more than 40% of the US population is Vitamin D deficient. The body manufactures Vitamin D, so why is deficiency wide spread? Indoor living, aging, and many other factors are behind this virtual pandemic. How can you measure your vitamin D levels? How can you get enough? Isn’t fortified milk enough? Should you take a supplement? Which one? Continue reading “Vitamin D and the Eye: Uveitis, Macular Degeneration, and Dry Eye”

Teen Myopia Increase Blamed on Electronics and Screens

teen myopia electronics screenSmartphones, computers, tablets, and televisions are being blamed for a sharp increase in teenagers’ need for eyeglasses in the United Kingdom. The number of teens who need glasses nearly doubled, from 20% in 2012 to 35% in just four years later.[1. Scrivens Opticians report, 2019] Myopia was the diagnosis for 66% of these teens. Myopia, or nearsightedness, makes distant objects look blurry. Excessive up-close focusing is a risk factor for developing myopia.

Ginkgo, Garlic, and Ginseng Research on Eye Health and Dementia

garlic ginseng ginkgoThree time-tested supplements stand out as champions for eye and brain health: garlic, ginseng, and ginkgo. Research on these supplements backs up why they have been used for thousands of years. Garlic plays an important role in all three major traditional medicines–Traditional European Herbal Medicine, Ayurveda, and Traditional Chinese Medicine. Ginseng and ginkgo are crucial herbs in Traditional Chinese Medicine. Do these supplements work? Are they beneficial for aging brains and eyes? What does the research show? Continue reading “Ginkgo, Garlic, and Ginseng Research on Eye Health and Dementia”

Why Astaxanthin Helps Prevent Sun Damage

Astaxanthin protects from sun damageAstaxanthin is a potent antioxidant that helps prevent sun damage to the body by blocking free radical damage. This bright red molecule forms in certain algae, pink seafood, and yeast. Unlike beta-carotene, this carotenoid crosses the blood-brain barrier to help maintain healthy brain function. Astaxanthin helps the brain by promoting neurogenesis, the generation of new brain neurons. This nutrient also supports existing neurons by reducing oxidative stress. Scientists have found that astaxanthin can protect against cumulative sun damage to the eye. This nutrient may help reduce the risk of eye disease such as macular degeneration. It may also protect against cataracts and vision loss from glaucoma. In addition, related carotenoids called lutein and zeaxanthin block blue light and work synergistically with astaxanthin. Continue reading “Why Astaxanthin Helps Prevent Sun Damage”

Chronic Fatigue Virus not Associated with Virus XMRV

The Independent reports that US government officials have persuaded the editors of the Proceedings of the National Academy of Sciences to hold off from publishing a scientific paper establishing the link between chronic fatigue syndrome and the virus XMRV. The study supporting the link was headed by virologists working for the Food and Drug Administration, but scientists at the Centers for Disease Control have authored another study that contradicts the FDA findings and finds no trace of XMRV in CF patients.

There has been controversy over this new cause of CF ever since an initial paper was published in the journal Science in October, 2009 as researchers have spoken out on both sides of the issue.  Some see an obvious connection between the virus and chronic fatigue syndrome, while others state that CF sufferers are no more likely to have the virus than healthy people.[1. Retrieved from https://www.independent.co.uk/news/science/study-that-solves-chronic-fatigue-syndrome-blocked-2022195.html.]

Update: 2014 recent research does not find such an association.[2. Irlbeck DM, et al. (2014). No association found between the detection of either xenotropic murine leukemia virus-related virus or polytropic murine leukemia virus and chronic fatigue syndrome in a blinded, multi-site, prospective study by the establishment and use of the SolveCFS BioBank. BMC Res Notes. Aug 4;7:461.]

Update, 2016: Molecular biologists traced the development of XMRV to a propagation of the virus from cell lines in a lab mouse in about 1993.  The virus apparently spread through contamination of lab samples of prostate cancer and/or CFS. “Well-controlled experiments showed that detection of XMRV was due to contaminated samples and was not a marker of or a causal factor in prostate cancer or CFS.”[3. Johnson AD, et al. (2016). Xenotropic Murine Leukemia Virus-Related Virus (XMRV) and the Safety of the Blood Supply. Clin Microbiol Rev.  Oct;29(4):749-57.]

Brain Boosters for Seniors: Prevent or Support Alzheimer’s and Dementia

senior with brain dementiaAs we age, how can we prevent or support dementia, Alzheimer’s Disease, and other age-related brain diseases? Looking at the scientific research, much emphasis is on curing neurological disease after it is well-established. Reacting to a crisis is logical, though, after many years of research and money spent, there is still no cure. However, preventing a crisis is even better. Why wait for possible brain deterioration to affect your quality-of-life? Continue reading “Brain Boosters for Seniors: Prevent or Support Alzheimer’s and Dementia”

Halting Diabetic Retinopathy: Every Diabetic Patient’s Guide to Preserving Vision

diabetic retinopathyDiabetic retinopathy is a vision-stealing effect of diabetes. What causes diabetes, and how can you prevent it? Can diabetic patients prevent this eye disease? What can you do to halt diabetic retinopathy? How can patients preserve their vision?

Step 1: Don’t Get Diabetes

Avoiding Type 1 Diabetes is a virtual impossibility. Doctors do not know why the immune system attacks the pancreas. The underlying cause is typically genetic, but a trigger also seems to be needed. Type 1 is usually diagnosed in childhood and represents less than 10% of diabetic cases. Continue reading “Halting Diabetic Retinopathy: Every Diabetic Patient’s Guide to Preserving Vision”
