Vitamin D Protects Against Bloodstream Infection

vitamin D from the sunIn a recent study, hospital patients with higher levels of the vitamin were less likely to develop hospital-acquired bloodstream infection (HABSI).

This protective effect of vitamin D is an important finding. Boston researchers collected data from 2,135 patients of Boston hospitals from 1993 to 2010. The men and women had vitamin D levels measured before admission to the hospital. 48 hours after admission, their blood samples were Continue reading “Vitamin D Protects Against Bloodstream Infection”

Green Tea Antioxidants Reach the Eye – Study

green tea researchThis report, called “Green Tea Catechins and Their Oxidative Protection in the Rat Eye,” is the first to detail how all the eye tissue take in green tea’s antioxidants, called “catechins.” This research may ultimately show how green tea could help stave off glaucoma and other eye diseases.

Antioxidants are important because they attack free radicals, molecules that create oxidative stress. Significant research points to free radical damage as a potential cause of disease, damage and aging to the Continue reading “Green Tea Antioxidants Reach the Eye – Study”

Controversy over GMO “Golden Rice”

A variety of rice genetically modified to contain beta-carotene awaits approval in the Philippines. Supporters claim the rice could be an answer to the widespread Vitamin A deficiency in the country. They hope to see the “Golden Rice” in fields within the year, after it passes biosafety tests.

Beta-carotene is processed by the body and converted into Vitamin A. Vitamin A deficiencies lower immunity and can lead to blindness. Insufficient intake of this vitamin has been an ongoing problem in the Philippines, with Continue reading “Philippines’ GMO Golden Rice with Beta-Carotene Sparks Controversy”

AMD Inhibited by Lutein, Carotenoids, and Zeaxanthin Antioxidants

amd blind braille bookNew evidence continues to support dietary lutein, carotenoids, zeaxanthin, and meso-zeaxanthin as a means of inhibiting development of age-related macular degeneration (AMD). AMD is the leading cause of loss of vision in Western people over age 55.

A study published in 2010, in Archives of Biochemistry and Biophysics by the Department of Ophthalmology and Visual Sciences at University of Utah, found that production of singlet oxygen in the human retinal pigment epithelium (RPE) and choroid is prevented or reduced by lutein, zeaxanthin, and meso-zeaxanthin, which act as Continue reading “AMD Inhibited by Lutein, Carotenoids, and Zeaxanthin Antioxidants”

CoQ10 Deficiency and Supplementation of this Antioxidant

Example of CoQ10 SupplementCoQ10 deficiency and supplementation were explained in an article by Michael S. Pepper and his colleagues at the University of Pretoria in South Africa. The article in the March, 2013 issue of Nutrition Reviews covered both primary and secondary coenzyme Q10 (CoQ10) deficiency.

In primary CoQ10 deficiency, the body cannot properly synthesize CoQ10 because of genetic mutations. The gene sequences needed to produce the enzymes are incorrect.

Dose Size of Sleeping Pill Ambien Lowered Due to Negative Effects

sleeping pill is a quick fixThe Food and Drug Administration (FDA) has recommended that the block-buster sleeping pill Ambien (zolpidem) dose be lowered, especially for women, due to negative side-effects. The drug stays in women’s system much longer than in men’s. Too many car accidents the day after taking Ambien have lead to the government agency to halve the recommended dose for women, and re-consider the dose for men.

Retinitis Pigmentosa Argus II Retinal Prothesis FDA Approved

Argus II for retinitis pigmentosaThe first implanted device for adults with retinitis pigmentosa has been approved by the U.S. Food and Drug Administration. Called the Argus II Retinal Prosthesis System, the device includes a tiny video camera, a transmitter (on a pair of glasses), and a video processing unit. The patient’s retina is replaced with a prosthesis. The camera wirelessly transmits visual information to the retinal prosthesis to improve vision.

Flavonoids in Deeply Colored Berries Protect People From Disease

blueberries and raspberries antioxidantsA fruit cup of mixed berries is a powerful snack: deeply colored fruits are filled with flavonoids and other antioxidants that help protect the body from disease. Antioxidants help prevent free-radical damage, which is believed to be responsible for the onset of eye diseases such as cataracts and macular degeneration.

The colored flavonoids found in berries are called “anthocyanins”. These water-soluble pigments make plants shades of red, purple and blue. Berries also contain flavonoids called “quercetin” and “apigenin”. In the field or in the wild, these flavonoids help protect the plant from pests and insects.
