Low Vitamin B6, B12 & Selenium Intake Increases Disability Risk

A new study in the Archives of Internal Medicine has found that vitamin B6, B12, and selenium decrease risks of disability in Americans older than 65.

Women in the lowest 25% of B6, B12 and selenium intake had disability rates that were 35%, 39%, and 100% higher than the upper 75% of intake, respectively.

When trying to explain how these vitamins help decrease disability, researchers cited vitamin B6 and B12’s role in lowering levels of homocysteine, a protein that increases oxidative stress, and decreases both artery and brain health, as well as selenium’s role in protecting cells against oxidative damage.

Selenium Levels Linked to Risk of Epilepsy

80 patients who met the criteria of intractable epilepsy were compared to a normal control group of the same age, socioeconomic level and place of living. Serum selenium levels were significantly lower in the patient group compared to the control group.

Selenium is known as a micro-mineral beneficial for immune and cardiovascular function, but it may be a brain-protective nutrient as well.

Green Tea Exhibits Prebiotic Characteristics

Polyphenols in green, black, and oolong tea may preferentially suppress the growth of pathogenic bacteria in the gut, but not the growth of 'friendly' bacteria, acting as a prebiotic, says a new study from Singapore.

“Our data demonstrate that phenolic compounds have general inhibitory effects on intestinal bacteria. The level of inhibition varies depending on the bacterial species and chemical structure of the compound,” wrote Lee. Growth of the pathogenic E. coli and Salmonella typhimurium were most strongly inhibited by the tea polyphenols and their metabolites, as were strains belonging to the Bacteroides and Clostridium genera. The researchers report that the growth of the probiotic Bifidobacterium and Lactobacillus strains were less affected by the tea compounds.

Increased Vitamin D Protects Against Multiple Sclerosis

Confirming a Vitamin D Supplements May Lower MS Risk study published in 2004, Harvard researchers report higher levels of vitamin D in the body may reduce the risk of developing the neurological disease multiple sclerosis by as much as 62 per cent.

“If the association reported here reflects a true protective effect of vitamin D, increasing the vitamin D levels of adolescents and young adults could result in an important reduction in MS incidence,” wrote lead author Kassandra Munger. “Such an increase could be achieved using vitamin D supplements.”

A simple 25-hydroxyvitamin D blood test will determine if any further consideration is warranted.

Western Diet Linked to Colorectal Cancer Risk

The high calorie, low fiber dietary pattern associated with the Western diet are associated with a 39% increased risk of colorectal cancer compared to a Mediterranean diet, says new research from France.

Four dietary patterns were identified by the authors and classified as "healthy" (rich in fruit and vegetables, olive oil, and fish), "Western" (rich in processed meat, eggs, and butter, potatoes, processed grain products, and cheese), "drinker" (emphasis on alcoholic beverages, snacks, sandwiches and processed meat), and "meat eaters" (meat and poultry).

For those people whose diet closely matched the Western diet, the researchers calculated that the risk of adenoma was increased by 39 percent, while those with a diet closely matching the "drinker" pattern were associated with an increased adenoma risk of 42 percent, compared to the 'healthy' pattern.

The researchers believe the health effects of fish consumption in relation to colorectal cancer may lie in their content of the omega-3 fatty acids, that acts as a mediator of inflammatory responses. DHA and EPA are omega-3 fatty acids commonly found in fish and fish oil. Neptune krill oil is another important source of DHA and EPA.

Fish and Whole Grains Linked to Asthma Protection

An increased consumption of whole grains and fish reduces the risk of developing asthma by about 50 per cent, suggests a new study from The Netherlands.

High intakes of whole grains and fish were associated with a 54 and 66 per cent reduction in the probability of being asthmatic, respectively. The probability of having asthma with bronchial hyperresponsiveness, defined as having an increased sensitivity to factors that cause narrowing of the airways, was reduced by 72 and 88 per cent when children had a high-intake of whole grains and fish, respectively.

The researchers believe the health effects of fish consumption in relation to asthma may lie in their content of the omega-3 fatty acids, that acts as a mediator of inflammatory responses. DHA and EPA are omega-3 fatty acids commonly found in fish and fish oil. Neptune krill oil is another important source of DHA and EPA.

Natural Vitamin K2 Supplement Superior to K1 in Human Study

Natural Vitamin K2 as menaquinone-7 (MK-7) was shown to be superior to K1 in humans in several measurements, including markers of bone turnover, bioavailability and bioactivity in the body.

In the new study the research demonstrated that after supplementation, Natural Vitamin K2 as Mk-7 is more effective in both promoting markers of bone health, and counteracting vitamin K antagonists. The mechanism underlying this observation may be MK-7's much longer half-life time in the circulation, the better cofactor activity, and its dramatically higher bioactivity.

Resveratrol Reduces Fat and Boosts Endurance

  • First Aging Gene Shown to Accelerate Human Metabolism
  • Findings Suggest Broad Implications for the Treatment of Diseases of Aging Such as Diabetes

The study showed that treating mice with resveratrol increased mitochondrial biogenesis leading to increased exercise endurance and protection from diet induced obesity.

Mice were dosed with resveratrol daily in either normal chow or high fat chow. The mice on resveratrol lost weight due to decreased fat, and this was attributed to an increase in the number and function of mitochondria. The resveratrol-treated mice also exhibited improved insulin sensitivity and an increased metabolic rate. Notably, mice treated with resveratrol showed a two-times increase in exercise endurance.

Omega-3, Fiber, Vitamin E Linked to Lower Lymphoma Risk

A diet rich in omega-3 fatty acids, dietary fiber, beta-carotene and vitamin E offers significant protection against non-Hodgkin lymphoma, says a Swedish-Danish-American study.

“Overall, we found that eating fish and marine fats was associated with lower risk of overall non-Hodgkin lymphomas ,” Dr. Chang said. “We also found that consuming certain antioxidant vitamins, commonly found in some fruits and vegetables, was associated with lower risk of overall NHL and some common subtypes.”

Vitamin K Reverses Artery Hardening

A high-dose vitamin K supplement reduced calcium precipitates associated with hardening of the arteries by 37 per cent.

If the results can be reproduced in humans, high-dose vitamin K could have potential clinical implications for reducing arterial calcification, which is an important independent risk factor for the development of cardiovascular disease (CVD). “High vitamin K intake not only prevents calcification, but even regresses arterial calcifications,” lead researcher Leon Schurgers from Maastricht University said.

Beta-Glucan Reduces Insulin Response After Eating

Consuming foods containing beta-glucan reduces the insulin and glucose response after a meal, thereby easing a risk factor for diabetes and cardiovascular disease, says a new study.

“The results of the present trial suggest beneficial effects of foods containing beta-glucan from oats on carbohydrate metabolism, and on blood pressure in obese subjects.” In subjects with body mass index above the median (31.5 kg/m2), both systolic (8.3 mmHg) and diastolic (3.9 mmHg) blood pressures were lowered in the beta-glucan group compared to controls.

Vitamin K Improves Anticoagulation Control

Vitamin K improved anticoagulation stability for patients taking warfarin.

Anticoagulation control improved in 33 out of 35 patients receiving vitamin K supplementation and, of these, 19 fulfilled criteria for having stable control of anticoagulation. Of 33 patients, only 24 receiving placebo demonstrated some degree of improvement, with only seven of these fulfilling the criteria for having stable control.

Researchers concluded concomitant supplementation of vitamin K, can significantly improve anticoagulation control in patients with unexplained instability of response to warfarin.

Mediterranean Diet Olive Oil Fights DNA Oxidation

Scientists investigated the ability of the Mediterranean diet to protect DNA against oxidative damage and to reduce cancer incidence, focusing on olive oil and its phenolic content. Results of their trial showed olive oil reduces DNA oxidation, and increased olive oil consumption may contribute to reduced cancer rates.

They further concluded higher DNA and RNA oxidation in Northern European regions compared with that in the Central and Southern regions supports the contention that olive oil consumption may explain some of the North-South differences in cancer incidences in Europe.

Higher Serum Vitamin E Levels Lower Mortality Risk

After an earlier poorly reported study suggested vitamin E supplements could possibly increase all-cause mortality, researchers from the U.S. National Institutes of Health (NIH) and the National Public Health Institute of Finland found higher serum levels of vitamin E may reduce the risk of total and cause-specific mortality.

The study involved 29,092 Finnish male smokers, 10% of which took vitamin E supplements. Men in the highest quintile of serum alpha-tocopherol had 18-percent reduced risk of total mortality, compared to those in the lowest quintile; further, the risks of deaths due to cancer, CVD and other causes were reduced by 21 percent, 19 percent and 30 percent, respectively.

The researchers concluded higher circulating levels of alpha-tocopherol within normal range helped lower mortality in older male smokers.

Vitamin E Benefits Diabetics’ Arterial Health

High Vitamin E alpha-tocopherol levels in people with type 1 diabetes correlate with a lower risk of coronary artery disease (CAD), especially among those either suffering from renal disease or those taking vitamin supplements.

Scientists noticed a protective effect of alpha-tocopherol against CAD among antioxidant supplement users and those with renal disease. They concluded high alpha-tocopherol levels among patients with renal disease and those using vitamin supplements were associated with lower CAD risk in type 1 diabetes.

Magnesium Shows Promise For Migraines In Children

Migraines are present in children, affecting as many as 13 percent of them. Researchers at the Department of Neurology, Kaiser Permanente, Hayward, CA, report that magnesium has shown to be effective for migraines.

Researchers studied 118 children, giving 58 children the equivalent of 500 mg of magnesium oxide for 125 pound child and giving 60 children a placebo. Researchers found a significant decrease in the number of headaches in the magnesium group while also having much less severity of migraines when compared to the placebo group.

Migraines Associated With Increased Heart Attack Risk

Men who have migraine headaches face an increased risk of cardiovascular disease (CVD), in particular myocardial infarction (MI), a report from the Physicians' Health Study suggests.

In the study, researchers examined 20,000 men participating in the Physician’s Health Study and found that men with migraines had a 24% increased risk of major cardiovascular disease events, including a 12% increase in stroke and a 42% increased risk of heart attack.

Research has started to find effective ways to help deal with symptoms of migraine headaches. In two studies researchers found Coenzyme Q10 helped significantly decrease migraines. A 2003 study found that 500 mg of magnesium helps with migraine symptoms. Both Coenzyme Q10 and magnesium are known for their heart health benefits.

CoQ10, Alpha-lipoic Acid & Creatine Decrease Muscle Decline

A new study indicated that mitochondrial disorders have several things in common, including reduced production of ATP (the energy molecule in our bodies), increased reliance on non-oxygen energy sources and increased production of oxygen free radicals.

In this small Canadian study, patients with mitochondrial disorders were treated in a randomized, double-blinded, placebo-controlled manner with crossover using alpha lipoic acid, creatine monohydrate and coenzyme Q10.

The study suggested that combination therapies targeting common pathways of mitochondrial dysfunction showed favorable benefits in terms of markers of cellular energy.
