Cataracts & Nutrition

Friday, September 01, 2006

Loss of vision is the second greatest fear, next to death, among the elderly. Age related cataracts are one of the major causes of loss of vision worldwide. Approximately 20 million people in the United States have their vision obstructed by cataracts and 500,000 new cases are diagnosed annually.

DNA Nutrition Connection

Friday, August 25, 2006

Our genes are formed from microscopic double-strands of deoxyribonucleic acid (DNA). They are dependent on adequate nutrition for their structure and activity. By appropriately switching on and off (this is called transcription in the genome research world) our genes direct the behavior of our body's 60 trillion cells. Many genetic researchers consider our genes to be the Rosetta stone of health and disease.

Let's Get it On

Friday, August 04, 2006

"There are three topics in modern science that have caused more controversy than stem cells " the development of nuclear bombs, the notion that the sun is at the center of our solar system and the theory of evolution," so says Michael Stebbins, PhD, the director of biology policy for the Federation of American Scientists and a former US congressional fellow in science policy.

Ginkgo Biloba and Disease

Sunday, July 30, 2006

Ginkgo biloba has been used medicinally for thousands of years. It has become a very popular herbal supplement for its potential benefit in alleviating symptoms associated with peripheral vascular disease, demantia, asthma, and tinnitus.

Vision Loss Slowed by Antioxidants

Friday, July 28, 2006

Scientific evidence, as well as common sense, is mounting regarding the need for daily intake of the full-spectrum of micronutrients to protect eye health, in spite of the huge amount of B&L marketing dollars spent advertising the simplistic ARED formulation, which includes questionable amounts of beta-carotene and zinc.

Fish Oil Supplements Safer Than Fish

Friday, July 21, 2006

For optimal health of the whole body, including the eyes, the consumption of two or more servings of fish high in Omega-3 fatty acids per week is advocated by the American Heart Association, the American Medical Association, the FDA and the most recent edition of the peer-reviewed journal, Ophthalmology. However, fresh wat

Zeaxanthin and Diabetic Retinopathy

Friday, June 30, 2006

A large body of literature suggests the retina experiences increased oxidative stress in diabetes. Overproduction of superoxide by the mitochondrial electron transport chain activates nuclear transcription factors (NFkB) and the three major pathways postulated to be involved in the pathogenesis associated with retinal capillary cell apoptosis in diabetic retinopathy.

Beta-Carotene & The Smoker Revisited

Friday, June 23, 2006

An important study published in the American Journal of Epidemiology suggested that smokers who consume a wide variety of dietary antioxidants, including small amounts of natural beta carotene, have a substantially lower risk of developing lung cancer. This was not good news to the vitamin companies who aggressively market beta-carotene free "Smokers" AMD formulations.

Mitochondrial Oxidative Decay and Eye Disease

Friday, June 16, 2006

Mitochondria are the most complex organelles in the cell; they provide energy for all basic metabolic processes including those associated with the retina. They detoxify oxygen, function in calcium and iron homeostasis, and they play a key role in programmed cell death. Oxygen (free radical) damage is produced as an inevitable byproduct of mitochondria function. Mitochondria are particularly vulnerable to this damage as they contain their own DNA.

Nutrients, VEGF, and a Call to Action

Wednesday, June 14, 2006

The vascular endothelial growth factor (VEGF) therapy race has new contenders and this race may eventually prove to be as exciting as the Tour de France, particularly for those affected by the growing epidemic of wet macular degeneration.
