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.

The Paleo Diet and Eye Health

Thpaleo diet foodse Paleo Diet or “Caveman Diet” is trendy, but what effect could it have on the eyes? The idea is to eat like hunter-gatherers in the Stone Age. These early humans had no agriculture–and no processed foods. Nearly devoid of grains and dairy products, this diet focuses on meat, fruit, nuts, seeds, and vegetables. Continue reading “The Paleo Diet and Eye Health”

Longer Allergy Season Will Impact Eye Health

Do your seasonal allergies affect your eyes?  You probably will not be happy to hear that a study appearing in the Proceedings of the National Academy of Sciences projected that the allergy season will be longer in the upper latitudes of North America. Climate change has led to longer warm seasons. Warmer temperatures and extra humidity mean more pollen in the air. Controlling hay fever is more important than ever.

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”

Can Omega-7 Fish Oil Reduce Dry Eyes and Metabolic Syndrome?

chronic inflammation leads to metabolic syndromeScientists recently discovered a fat molecule that they called “palmitoleic acid”, a type of Omega-7 fatty acid. The substance appears to have special anti-inflammatory properties. Omega-7 occurs in certain fish oils and nuts. You may have heard of Omega-3 fatty acids, which come mostly from cold water fatty fish. Omega-3s reduce inflammation and heart disease risk. Omega-6 fatty acids occur in primarily in nuts and seeds, vegetable oil and grains. Omega-6 fatty acids are polyunsaturated fats. Omega-7s are monounsaturated fats, similar to olive oil. How are these types of fats different? What makes palmitoleic acid so important for preventing Type 2 diabetes and metabolic syndrome? Should you get them through food or supplements? How much should you take? Continue reading “Can Omega-7 Fish Oil Reduce Dry Eyes and Metabolic Syndrome?”

Glaucoma Study Finds Lower Intra-ocular Pressure from Mindfulness Meditation

meditation and glaucomaAccording to a small study published in the Journal of Glaucoma, a short course of mindfulness meditation reduced intraocular pressure (IOP) in patients with primary open angle glaucoma (POAG). The practice also normalized stress biomarkers and positively modified gene expression. Mindfulness meditation may be a therapeutic resource to reduce IOP and help glaucoma patients.

Low Antioxidant Levels Tied to Cataracts

cataract in one eyeA study conducted in North India found that people with low levels of antioxidants had higher levels of cataracts.1 A meta-analysis in 2015 found that too little vitamin E increased the risk of developing cataracts.2 Diabetes and fluctuations in blood sugar levels are risk factors for cataracts. Cataracts are the leading cause of total blindness in the world. Whether you have access to cataract surgery or not, prevention is better than disease. Scientists have studied specific nutrients and their links to cataract formation. What can you do to help prevent cataracts? Which fruits, vegetables, and other foods reduce cataract risk? If you have already developed cataract, can you do anything? Continue reading “Low Antioxidant Levels Tied to Cataracts”

Biohacking the Eyes for Vision Health

biohackingBiohacking refers to hacking human biology. The term “hacking” implies rogue, off-road, off-label, do-it-yourself activities. It stems from computer terminology, referring to illicitly defeating security protocols. However, the term has evolved to mean solving problems by undermining the established methods.

Regarding vision health, we have identified three types of biohacks: Nutrition Biohacks (Nutrigenomics), Quantified Self Biohacking (personal tracking devices), and Grinders (cyborgs devices). Continue reading “Biohacking the Eyes for Vision Health”

Avastin as Effective as Lucentis for Wet AMD

macular degeneration eyesA study, led by Dr. Daniel Martin, an ophthalmologist at the Cleveland Clinic’s Cole Eye Institute, has found that the cancer drug Avastin (bevacizumab) offers macular degeneration patients the same benefits as the drug Lucentis (ranibizumab), which was specifically formulated to treat the disease.
