Black Cohosh Inhibits Breast Cancer Growth

Black Cohosh was able to stop the progression of a human breast cancer cell line, scientists discovered.

The scientists determined that the most powerful component of black cohosh was able to inhibit the cancer cells by up to 50 percent.

Other scientists have found that black cohosh can reduce the cell-killing efficacy of certain chemotherapy drugs and increase the cell-killing efficacy of other drugs, so women who already have breast cancer and are taking chemotherapy drugs should consult with their physician before supplementing with black cohosh.

Vitamin C Increases Absorption of Antioxidants from Green Tea

Combining vitamin C with green tea or its extracts improves the absorption of antioxidants found in the tea, scientists have reported in a new study.

Epidemiological studies have suggested that green tea catechins may play a role in cognitive enhancement, maintaining proper weight and lowering risk of certain cancers. However, after drinking green tea, absorption of the catechins found in green tea can vary.

Vitamin C at a dose of 30 mg in 250 mL of tea significantly increased catechin stability of EGC, EGCG, EC, and ECG to 74, 54, 82, and 45 percent.

Omega-3 Fatty Acid Prevents Parkinson’s Disease

Scientists have discovered that the omega-3 fatty acid DHA can prevent the development of Parkinson’s disease in mice.

The scientists found that the animals on the omega-3-rich diet did not exhibit brain damage from the MPTP, whereas the mice fed the ordinary diet experienced all the Parkinson’s-like effects of MPTP exposure, including a 31 percent drop in dopamine-producing neurons and a 50 percent decrease in dopamine.

The researchers concluded that excessive amounts of omega-6 fatty acids in the brain and low amounts of the omega-3 fatty acid DHA may increase the susceptibility to Parkinson’s.

Multiple Dietary Supplements Associated with Better Health

Individuals who consume a number of nutritional supplements were found to have better biomarkers of health than people who do not consume any supplements and people who only consumed a multivitamin/multimineral.

Scientists conducted a study involving 278 long-term users of multiple dietary supplements. At least half of the subjects in the multiple dietary supplements group consumed: a multivitamin/mineral, B-complex, vitamin C, carotenoids, vitamin E, calcium with vitamin D, omega-3 fatty acids, flavonoids, lecithin, alfalfa, coenzyme Q10 with resveratrol, glucosamine, and an herbal immune supplement.

After adjusting for a number of confounding factors, the researchers found that the users of multiple dietary supplements had better biomarkers of health, as compared to individuals who did not take nutritional supplements or who consumed only a multivitamin/multimineral.

Phosphatidylcholine Helps Ulcerative Colitis Patients Withdraw from Steroids

Ulcerative colitis patients may be able to withdraw from steroids more easily when they are consuming phosphatidylcholine.

Half of the phosphatidylcholine recipients (15 of 30) achieved complete withdrawal from steroids and a reduction in their disease activity score of up to 50 percent while only 10 percent of placebo recipients (3 of 30) achieved the same improvements. Twenty-four phosphatidylcholine recipients (80 percent) and 3 (10 percent) placebo recipients discontinued steroid therapy without experiencing any worsening of disease.

Lack of Sunlight May Increase Lung Cancer

Lack of sunlight increases the risk of lung cancer, suggests a study of rates of the disease in over 100 countries, published in the Journal of Epidemiology and Community Health. Lung cancer kills over a million people every year around the globe.

The link between cancer and sunlight is chemically plausible, say the authors, because laboratory research has shown that vitamin D can halt tumor growth by promoting the factors responsible for cell death in the body.

Vitamin D Helps Promote Cellular Longevity

A new study has found that vitamin D-3 may slow aging by increasing the length of telomeres, the section of a chromosome that shortens as we age and when the body is subjected to increased inflammation.

Vitamin D is an antioxidant that is known to benefit skin, bone, and muscle. It also reduces inflammation. Vitamin D’s benefits are thought to be due to its ability to help establish healthy C-reactive protein (CRP) levels.

The researchers found that those in the highest 20% of vitamin D blood levels had an average of 108 more base pairs than those in the lowest 20%of vitamin D blood levels. This LTL difference equated to five years of chronological age. Vitamin D supplement users also had longer LTLs than did non-users.

Cell-Death Receptor Links Cancer Susceptibility and Inflammation

When intact, TRAIL and its receptor decrease the influx of inflammatory cells and molecules that can lead to cancer. New models of cancer have suggested a link between inflammation and cancer in the last five years, and El-Deiry is in the early stages of trying to understand this connection with respect to the TRAIL pathway.

El-Deiry and his team are now looking within tumor tissue for inflammatory molecules as clues to how cancer and inflammation are coupled. “Our work with TRAIL and its receptor in mouse models represents a new way to look at cancer susceptibility and its potential therapy in humans as well as new ways to decrease debilitating radiation side-effects experienced by cancer patients,” says El-Deiry.

Chronic Pain Associated with Low Vitamin D Level

Chronic pain is associated with very low vitamin D levels.

Studies have shown that once vitamin D levels were returned to normal, the pain was reduced dramatically or even disappeared.

Low Cholesterol Makes It Harder to Recover from Stroke

People are at an increased risk of memory problems and greater disability after stroke if they have low levels of “good” cholesterol and high levels of homocysteine, an amino acid acquired mostly from eating meat.

Researchers found several factors predicted memory and disability problems after stroke: increased age, non-Caucasian race, recurrent stroke, diabetes, stroke in the left hemisphere of the brain, higher levels of homocysteine and lower levels of high-density lipoproteins (HDL), otherwise known as “good” cholesterol. People with low levels of HDL, high levels of homocysteine, and diabetes are twice as likely as those without such problems to have poorer cognitive function and greater disability after stroke.
