Quercetin reduces blood pressure in adults with hypertension
Quercetin, an antioxidant found many foods including onions, berries and apples, is associated with a reduced risk of heart disease and stroke. Supplementation with quercetin has been shown to reduce hypertension in animal models, but until now has never been tested in hypertensive humans.
Researchers at the University of Utah, in collaboration with USANA Health Sciences, conducted a randomized, double-blind, placebo-controlled, crossover study to test the effectiveness of quercetin supplementation in lowering unhealthy blood pressure levels. The subjects were divided into two groups: prehypertensives (120-139 mm Hg systolic/80-89 mm Hg diastolic) or stage 1 hypertensives (140-159 mm Hg systolic/90-99 mm Hg diastolic).
The participants were given either 730 mg quercetin/day or placebo for 28 days. Blood pressure remained unchanged in prehypertensives after supplementation with quercetin.
In contrast, stage 1 hypertensive subjects showed significant reductions in both systolic (-7 mm Hg) and diastolic (-2 mm Hg) blood pressure after quercetin supplementation. This is the first published study to show that quercetin supplementation can reduce blood pressure in hypertensive adult humans.
Additionally, it is important to note that quercetin supplementation did not influence the blood pressure of non-hypertensive individuals. J. Nutr. 137:2405-2411, November 2007

CoEnzyme Q 10 Protects Nerve Cells
CoEnzyme Q10 protects nerve cells
CoEnzyme Q 10 is a co-factor necessary in the metabolism of energy in the cell brain called the mitochondria. Most of our energy is created in our large muscles including the heart. Our bodies manufacture CoEnzyme Q10 but as we age we make less and less. Several studies are not being done as to the effects of supplementing with this enzyme and what other body systems the CoEnzyme Q 10 has an effect on.
CoEnzyme Q10 has shown the ability to protect nerve cells and potentially lower the risk of various degenerative diseases. Cells in the brain and nervous system depend on optimal mitochondrial function for energy.
A research study published in the journal Neurobiology of Disease showed that oxidative stress causes mitochondria to produce excessive free radicals, leading to nerve cell damage and destruction. Due to its function in the mitochondrial energy process and its role as an antioxidant, researchers evaluated CoEnzyme Q10 for its ability to protect nerve cells.
The results of this study revealed that CoEnzyme Q10 inhibits the production of free radicals by the mitochondria and stabilizes the mitochondrial membrane when nerve cells are subjected to oxidative stress. CoEnzyme Q10 may therefore have a potential benefit in reducing the risk of various neurodegenerative diseases.

Age Related Macular Degeneration
Macular Degeneration risk is reduced in adults with high intakes of lutein and zeaxanthin
Age-Related Macular Degeneration (AMD) is a degenerative eye disease that causes damage to the macula (central retina) of the eye, impairing central vision. In a recent large study, participants with the highest intakes of the carotenoids lutein and zeaxanthin had significantly lower risk of AMD compared to those with low intakes.
Age-Related Macular Degeneration (AMD) is a degenerative eye disease that causes damage to the macula (central retina) of the eye, impairing central vision. People affected by Age-Related Macular Degeneration have difficulty reading, driving and performing activities that require clear central vision. AMD is the most common cause of vision loss in developed countries. A recent report published in the September, 2007 issue of the journal Archives of Ophthalmology added more evidence to support previous research showing that carotenoids zeaxanthin and lutein are protective against AMD.
Dark green leafy vegetables are the primary dietary sources of lutein and zeaxanthin, but they are also found in some other colorful fruits and vegetables. Average dietary intake in the U.S. is only 2 mg/day, far below the 6 mg/day level most studies indicate as a minimum needed to reduce the risk of AMD. In the current report, members of the Age-Related Eye Disease Study (AREDS) Research Group evaluated the diets of 4,519 AREDS participants aged 60 to 80 years. Retinal photographs were used to divide the subjects into five categories of macular disease severity, from individuals with little or no evidence of macular degeneration (the control group) to severe, neovascular disease.
Dietary questionnaires were analyzed for lutein, zeaxanthin, beta- carotene, lycopene, and other nutrient levels. Participants whose intake of lutein and zeaxanthin were greatest had a significantly lower risk of AMD than those whose intake was least, and were less likely to have large or extensive intermediate drusen, the deposits on the retina or optic nerve that characterize the disease. No risk reductions were associated with the other nutrients examined in this study.

Vitamin D Helps with Pregnant Women Risks
Vitamin D supplementation in early pregnancy may help prevent preeclampsia
Vitamin D deficiency early in pregnancy is associated with a five-fold increased risk of preeclampsia, according to a new study published in the Journal of Clinical Endocrinology and Metabolism.In newly published research, scientists evaluated data and blood samples taken from women and newborns between 1997 and 2001 enrolled in a study designed to examine risk factors for preeclampsia. This serious complication of pregnancy is marked by elevated blood pressure and edema (swelling) of the hands and feet, and is a leading cause of premature delivery and maternal and neonatal complications including death.
The results of the study show that a maternal vitamin D deficiency early in pregnancy is a strong, independent risk factor for preeclampsia. This increase risk continued even after adjusting for other known risk factors such as race, ethnicity and pre-pregnancy body weight.
Another concern was the fact that many of the women were taking prenatal vitamins, which typically contain 200 to 400 IU of vitamin D.
"Even a small decline in vitamin D concentration more than doubled the risk of preeclampsia," noted James M. Roberts, M.D., senior author of the study. "And since newborn's vitamin D stores are completely reliant on vitamin D from the mother, low vitamin levels also were observed in the umbilical cord blood of newborns from mothers with preeclampsia." The researchers concluded that maternal vitamin D deficiency may be an independent risk factor for preeclampsia and vitamin D supplementation in early pregnancy should be explored for preventing preeclampsia and promoting neonatal well-being.
