Age-related cataracts are the leading cause of low vision and blindness throughout the world. Up to 30% of people over the age of 50 will develop them. By age 75, about 70% will have cataracts. Surgery to remove cataracts has become almost routine. Continue reading →
The association between vision and diabetes is not too well-known, but it’s definitely one to be aware of. Diabetes is a disease primarily caused by insulin resistance, of course, but along with blood sugar problems, diabetes can also affect the retinas of the eyes. Diabetic retinopathy, as the condition is called, is the most common reason for blindness in American adults. Continue reading →
Astaxanthin is believed to be the most potent antioxidant nature has to offer. In terms of antioxidant power or potency, astaxanthin is 550 times stronger than vitamin E, and 6,000 times stronger than vitamin C
You’re probably familiar with all sorts of mythologies promoted as “truisms” in modern medicine: Flu vaccines prevent the flu (they actually don’t), CT scans are harmless (they aren’t), chemotherapy works to save lives from cancer (it actually causes cancer), and so on. There are all sorts of falsehoods in dentistry, too: Mercury fillings are safe for you! (They aren’t.) Gum health Continue reading →
The second most common cause of vision loss in people over 65 is macular degeneration. In this condition, the retina is injured. This condition affects close to two million people in the U.S., a number expected to rise as the population ages.
Macular degeneration happens when the macula has deteriorated to the point where your central vision is blurred, Continue reading →
While there’s no official definition of the term super food, the generally implied idea is a fruit or vegetable that is particularly nutritious and beneficial to your overall health and wellness, with high phytonutrient content. By that definition, kale should have a spot in the top ten. If you want to be healthy, there’s no avoiding the leafy green vegetables, and kale is one of the most nourishing. It Continue reading →
Carotenoids are back in the news again. These are the naturally occurring, fat-soluble pigments that provide the bright colors you see in certain plants and even animals. They are responsible for the red, yellow, and orange color of fruits and vegetables, and are also found in many dark green vegetables. Continue reading →
While a member of the carotenoid family, astaxanthin has many unique properties that put it in a class of its own. For example, it cannot function as a pro-oxidant, making it a highly beneficial antioxidant. It’s also unique in that it can protect the entire cell—both the water- and fat-soluble parts—from damage
While you can easily obtain most of the carotenoids you need from your diet, getting therapeutic amounts of astaxanthin through diet alone is difficult. You’d have to consume three-quarters of a pound of wild-caught sockeye salmon, which contains the highest amounts of astaxanthin of all the marine foods, to receive the same amount of astaxanthin you’d get in a 4mg capsule if you were to take a supplement
Health benefits of astaxanthin includes protection against age-related macular degeneration (the most common cause of blindness), Continue reading →
For people at a higher risk of losing central vision as they age, eating sufficient levels of certain dietary nutrients could help protect their eyes.
A new study finds that among people with a genetic susceptibility to macular degeneration — vision loss caused by erosion of the retina — those who ate higher levels of zinc, antioxidants, or omega-3 fatty acids cut their risk of developing the disease by as much as a third compared with those who ate lower levels of the nutrients.
“Therefore, clinicians should provide dietary advice to young susceptible individuals to postpone or prevent the vision-disabling consequences of (age-related macular degeneration),” the researchers wrote in the journal Archives of Ophthalmology. Age-related macular degeneration is common, accounting for half of all cases of blindness in developed countries, they note.
