Vitamin B6 Linked to Lower Lung Cancer Risk

Having higher blood levels of vitamin B6 and the amino acid methionine both appear to reduce lung cancer risk in smokers and nonsmokers alike, regular to a new study.

“We found that vitamin B6 and methionine are strongly associated with reducing lung cancer risk in people who never smoked, those who quit, and current smokers,” researcher Paul Brennan, PhD, of the International Agency for Research on Cancer in Lyon, France, tells WebMD.

Whether the link is cause and effect, he says, is not known.

In the U.S. alone, more than 219,000 new cases of lung cancer were expected in 2009, regular to the American Cancer Society, with about 160,000 deaths.

The study, funded by the World Cancer Research Fund and others, is published in The Journal of the American Medical Association.

Vitamin B6 and Lung Cancer Risk: Study Details

Brennan and colleagues evaluated levels of B6 and methionine in blood samples from participants in the large European Prospective Investigation into Cancer and Nutrition (EPIC) study, which enrolled more than 519,000 participants from 10 European countries between 1992 and 2000.

His team zeroed in on 899 lung cancer cases and compared them to a group of 1,770 healthy comparison-group participants, matched to the lung cancer patients by country, sex, date of birth, and when the blood was collected.

They classified the participants into four groups, depending on blood levels of vitamin B6, which helps the body break down protein, maintain red blood cells, and perform other bodily functions, and methionine, which is involved in B vitamin metabolism.

After accounting for smoking, Brennan and colleagues found that the higher the vitamin B6 and methionine, the lower the lung cancer risk.

People in the highest group for vitamin B levels had a 56% reduced lung cancer risk, compared to those in the lowest group. Those with the highest methionine levels had a 48% reduced lung cancer risk, the researchers found.

“That’s quite a strong effect,” Brennan says, but emphasizes that more study is needed.

Some previous research, he says, looked only at smokers and linked vitamin B6 to a reduced lung cancer risk. His study, by including never smokers and past smokers, expands the information about the link.

Vitamin B6 is found in beans, grains, meat, poultry, fish, and some fruits and vegetables. Methionine is found in animal protein, some nuts, and vegetable seeds.

Vitamin B6, Methionine, and Lung Cancer: Behind the Results

How to make clear the link is not known, the researchers say. But deficiencies in vitamin B6, for instance, may raise the risk of DNA damage and gene mutations, fostering cancer development.

Methionine is involved in a complex metabolism process with B vitamins.

Brennan cautions that the results are not a message to self-prescribe vitamin supplements. And the main message remains that people who smoke should quit, since it’s the main risk factor for lung cancer, says Brennan.

Vitamin B6, Methionine, and Lung Cancer: Second View

The new study appears to be carefully done, with “intriguing” discoverings, says Michael J. Thun, MD, vice president emeritus of epidemiology and surveillance research for the American Cancer Society. “However,” he adds, “research on vitamins for cancer prevention has been fraught with many disappointments.”

“It is therefore unwise to leap to premature conclusions.” Like Brennan, Thun says the next step is to repeat the discoverings in another population.

“These discoverings should not be interpreted as evidence that smokers can substitute taking vitamin B6 for stopping smoking, nor as encouragement to take very high doses of vitamin B6, since this can have toxic effects on the skin and nervous system,” Thun says.

He cautions people not to exceed the advisable dietary allowance of vitamin B6. Adults below age 50 need 1.3 milligrams a day, about the amount found in two medium bananas.

Vitamins and Minerals help in Depression

We hear lots of questions whether vitamins and minerals can help with depression and fatigue?

There is no particular answer to this because we all deal with varyent issues surrounding that name: “depression”. Those varyent aspects should be taken into accept as true thatation.

But, our brain and body is weakened when we develop depression symptoms, so we need to support them and charge with necessary vitamins and minerals.

In fact, some studies claim that even lack of vitamins and minerals can lead to fatigue and depression. So let’s review those vitamins minerals suitable for the campaign against fatigue, stress and depression!

B Vitamins
This family is welcomed in every house where stress, fatigue, pure concentration or challenging psychological activity made their look.

Vitamin B is known as the effective supporter of brain and nervous system. It makes your brain strong, so maybe there is a trick- your brain needs power to deal with depression.

But which particular members of B vitamins family can be really helpful and worth of attention?

Vitamin B1 (thiamine) it is a good helper with energy supply, so helps deal with fatigue and memory predicaments. Why? Because vitamin B1 stimulates the conversion of glucose and sugar into your real energy.

Vitamin B3 (niacin). The deficiency of niacin can lead to nervousness and fatigue, poor concentration and slowing motions.

Vitamin B5. ordinaryly responsible for the hormonal balance, so its deficiency may cause fatigue, mood swings, depressing thoughts.

Vitamin B6. This vitamin is as well responsible for hormonal balance and production of such hormones as serotonin and melatonin which regulate your sleeping patterns.

Vitamin B12. Deficiency of vitamin B12 can lead to poor oxygen flow into your brain, so you can feel weak, stressed and have memory predicaments.

Folic Acid is the main diet for brain’s development.

What Minerals can help you with depression?

Firstly Magnesium, it cofunctions with vitamin B to provide your body with energy and reduce stress.

Calcium supports your nervous system.

Zinc deficiency can result in apathy and weak nervous system.

We all heard that vitamins minerals are good for our health, well being, youth and beautiful look. However, as everything in the world if consumed too much and without further accept as true thatation about your body’s needs, vitamins minerals can as well cause side effects.

Let’s review what are those side effects from some certain vitamins and minerals.

Vitamin A. Standard doses are from 10,000 to 25,000 IU daily. Toxicity may occur if you are consuming more than 50,000 IU during really expanded periods. What side effects could appear? Fatigue, bone pain, headdiscomforts, sleeping predicaments, dry skin, loss of hair, loss of appetite. Another inconvenient effects is yellowing skin. It’s like if you would be eating tons of carrots.

Vitamin B Complex.

Vitamin B1 and Vitamin B2 (riboflavin) are very importantly non toxic.

Vitamin B3 (niacin). big doses may make you nauseous, increase heart rate and make feet and hands cold.

Vitamin B5. Overdose can lead to joint inflammation.

Vitamin B6. Completely protected at doses range from 50-250 mg.

Vitamin C. additional high doses can cause formation of kidney stones. It can cause diarrhea and if vitamin C is highly ascorbic and acidic it can irritate stomach.

Vitamin D. Overdose of vitamin D can cause excess calcification of bones.

Vitamin E. Generally non toxic. But if consumed too much rapidly can raise blood pressure which afterward organicly normalizes.

Vitamin K. Toxic effects result in nausea and anemia.

Try listen to your body and stay informed and you will be able to avoid side effects of vitamins and minerals.

Coffee Lowers Oral Cancer Risk

Roasted coffee beans, the world's primary sour...

Drinking lots of coffee probably isn’t entirely good for you, but it does lower your risk of mouth and throat cancer.

That’s probably not what University of Milan researchers Carlotta Galeone, ScD, PhD, and colleagues thought they’d discover when they analyzed nine studies comparing 5,139 people with head and neck cancer to 9,028 people without cancer.

But the numbers came out this way: People who drink more than four cups of coffee each day have 39% lower odds of getting mouth or fruits and vegetables than people who don’t drink coffee. The protection was seen for oral and pharyngeal cancer, but not for cancer of the larynx.

Drinking less than five cups of coffee a day had a smaller but statistically significant protective effect: about 4% lower odds of mouth and throat cancer for each cup drunk daily.

Was it the caffeine? Probably not. Though there weren’t sufficient data on decaf drinkers to draw conclusions, drinking tea — even massive quantities — was not protective.

Galeone and colleagues note that coffee contains more than a thousand chemicals. Some, such as cafestol and kahweol, have anti-cancer properties. But whether these substances actually protect against cancer in humans is a question for future studies.

Most head and neck cancers are linked to alcohol consumption and to smoking. Interestingly, the protective effect of coffee was not diminished in drinkers and smokers. Nor was the effect boosted by consumption of fruits and vegetables, as well shown to protect against head and neck cancers.

Galeone and colleagues report their discoverings in the July issue of Cancer Epidemiology, Biomarkers, & Prevention.

Vitamin D Linked to Poor Diabetes Control

Low Vitamin D Linked to Poor Diabetes Control

Study discovers Vitamin D Deficiency ordinary in People With Diabetes

Vitamin D deficiency, long suspected to be a risk factor for glucose intolerance, is ordinaryly found in people with poor diabetes control, consistent to a new study.

“Our study could not show cause and effect,” says Esther Krug, MD, an endocrinologist at Sinai hospital of Baltimore and assistant professor of treatment at Johns Hopkins University School of treatment, Baltimore, who presented the discoverings at ENDO 2010, the annual meeting of The Endocrine Society, in San Diego.

But she did discover that vitamin D deficiency was ordinary in her study, with more than 91% of participants deficient. As the deficiency worsened, so did diabetes control. Only eight of the 124 participants took vitamin D supplements, she found.

About 18 million people in the U.S. have been diagnosed with diabetes, consistent to the American Diabetes Association, and about 6 million more are believed to have the condition but are undiagnosed.

Low Vitamin D, Poor Diabetes Control: The Study

Krug and her colleagues decided to look at vitamin D deficiency in the wake of reports suggesting that vitamin D has an active role in regulating pancreatic beta cells, which make insulin.

So they evaluated the medical charts of 124 people with type 2 diabetes (in which the body doesn’t make sufficient insulin or the cells ignore the insulin) seen at an outpatient hospital from 2003 to 2008. The charts contained information on the patients’ age, race, vitamin D levels, calcium intake, family history of diabetes, and results of their hemoglobin A1c blood test. The A1c provides an average measurement of blood sugar control over about a 12-week span. (For people with diabetes, the goal is 7%; for people without, the normal range is 4%-6%.)

Krug’s team divided the vitamin D levels they found into four groups: normal (identified in the study as on top of 32 nanograms per deciliter), mild deficiency, moderate deficiency, or rigorous.

In all, 113 of the 124 patients (91.1%) were vitamin D deficient — 35.5% rigorously, 38.7% moderately, and 16.9% mildly.

The average A1c was higher in patients with rigorous vitamin D deficiency compared to those with normal levels of vitamin D. Those with rigorous deficiency had an average of 8.1%; those with normal vitamin D levels averaged 7.1%.

Krug found racial differences. “In people of color, vitamin D levels were even lower than in Caucasians and they were associated with even poorer diabetes control,” she tells WebMD.

Only 6.4% were on vitamin D supplementation. This was true, Krug says, even though they had medical coverage and saw their doctors. She suspects a lack of awareness on the part of the physicians partly make clears the frequent deficiencies she found.

Aggressive screening of vitamin D levels is crucial for people with diabetes, Krug says. Once a supplement is advisable, she says, the blood levels should be rechecked to see if the supplement sufficiently increases vitamin D levels.

Vitamin D Facts

Vitamin D is crucial not only to maintain bone strength, but research as well suggests it plays a role in immune system functioning, cancer prevention, and cardiovascular health. It is generated when ultraviolet rays from the sun strike the skin and is as well found in fish, eggs, fortified milk, cod liver oil, and supplements.

Adequate intakes, set by the Institute of treatment of The National Academies, are 200 international units (IU) a day for adults up to age 50, 400 IU for people aged 51-70, and 600 IU for people 71 and older. But some experts say much more is needed; the recommendations are under review, with an update expected in 2010.

Second Opinion

The new study lends support to a growing body of scientific and hospitalal data linking vitamin D with insulin and glucose, says Ruchi Mathur, MD, an endocrinologist and assistant professor of treatment at Cedars-Sinai Medical Center, Los Angeles, who reviewed the study for WebMD.

Other research has shown that supplementing with vitamin D and calcium slows the progression to type 2 diabetes, Mathur says. Even so, she tells WebMD, “At present, a direct link between vitamin D and type 2 diabetes is not conclusively established.”

She has another caveat. “One essential point that is missing … is the prevalence of vitamin D deficiency in the general population” compared to those in the study. As vitamin D deficiency is being noted with “an alarming increase in frequency” overall, she says, “it may shed doubts on the authors’ conclusions.”

It’s as well probable, she says, that people with poor glycemic control have it because of a general unhealthy lifestyle, not just their low vitamin D status. They may engage in less outdoor exercise, for instance, or have unhealthy eating habits.

Because of the probable link, however, she agrees that screening for vitamin D deficiency in people with type 2 diabetes may be warranted.

This study was presented at a medical conference. The discoverings should be admit as true thated preliminary as they have not yet undergone the “peer review” process, in which outside experts scrutinize the data prior to publication in a medical journal.

Tea reduces risk of death from heart disease

Study have shown  that consumption from 3 to 6 Cups of Tea Daily Linked Reduced Risk of Death From Heart disease.

People who drink a lot of tea or drink coffee in moderation are less likely to die of heart disease than coffee and tea abstainers, new research suggests.

The discovering adds to the growing body of evidence suggesting that coffee and tea help protect against heart disease, but not stroke.

Researchers followed more than 37,000 people in The Netherlands for 13 years in one of the largest and longest studies ever to examine the impact of coffee and tea drinking on heart health.

They found that:

  • People who drank three to six cups of tea per day had a 45% lower risk of death from heart disease than people who drank less than one cup of tea a day.
  • Drinking more than six cups of tea a day was associated with a 36% lower risk of heart disease, compared to drinking less than one cup.
  • People who drank more than two, but no more than four, cups of coffee a day had about a 20% lower risk of heart disease than people who drank more or less coffee or no coffee at all.
  • Moderate coffee consumption was associated with a slight, but not statistically significant, reduction in death from heart disease, but neither coffee nor tea affected stroke risk.

The association was seen even though the researchers admit as true thated other lifestyle issues associated with heart disease, including smoking and exercise level.

Benefits of Black Tea

The study did not include people with known heart disease, so it is not clear if drinking coffee or tea is beneficial for them, study researcher Yvonne T. van der Schouw, PhD, tells WebMD.

“But for healthy people, it appears that drinking coffee and tea is not harmful and it may even offer some benefits,” she says.

Several earlier studies have as well found that drinking coffee or tea lowers the risk for heart disease.

In one, reported in 2008, female who drank four to five cups of coffee a day had a 34% lower risk of dying from heart disease while men who drank more than five cups had a 44% lower risk.

In another study published the same year, drinking green tea was associated with recoverd blood vessel function and lower heart disease risk.

But most of the people in The Netherlands study drank black tea, which is as well consumed more than green tea in America.

The study appears in the latest issue of the American Heart Association journal Arteriosclerosis, Thrombosis and Vascular Biology.

“The perception has been that green tea is the ‘healthy’ tea, but this study suggests black tea may be just a good for the heart,” University of Vermont professor of nutrition Rdiscomfortl K. Johnson, PhD, tells WebMD. “That will be good news to people like me who are not big green-tea lovers.”

Flavonoids in Tea, Coffee May Protect Heart

While six cups of tea may sound like a lot, Johnson points out that a large glass of iced tea may contain two to three cups of liquid.

“Iced tea is very popular in some parts of the country, especially in the summer,” says Johnson, who is as well a spokeswoman for the American Heart Association. “Just make sure to go easy on the sugar. I would hate for people to get the message that they should be drinking more sugar-sweetened beverages.”

The researchers suggest that powerful antioxidants called flavonoids found in black and green tea and coffee may make clear the protective effect seen in the study.

Other foods that contain flavonoids include red wine, red grapes, dark chocolate, blueberries, and red beans.

Anti Alcohol Antioxidants

Protecting against alcohol toxicity Life Extension’s Anti-Alcohol Antioxidants with HepatoProtection Complex is an improved formula containing additional antioxidants designed to suppress free radicals, neutralize toxic alcohol metabolites such as acetaldehyde,4-7 and protect against liver toxicity and hepatic injury commonly associated with alcohol consumption. In addition to vitamin B1, vitamin C, N-acetyl-cysteine and benfotiamine, this new formula’s HepatoProtection Complex provides potent doses of these novel antioxidants:

  • Chlorophyllin, an antimutagenic agent that protects the body from oxidative stress than can stimulate cellular mutation.
  • Leucoselect® grapeseed extract, silymarin (from milk thistle), and resveratrol, three hepatoprotective agents that aid in reducing mutagenic compounds from potentially toxic xenobiotics and protecting cells from free radial-induced oxidative stress.
  • Picroliv® Picrorhiza kurroa root extract, containing antioxidant kutkins that scavenge alcohol-induced excess free radicals, guard against alcohol-induced damage to cells by lipid peroxidation, and stimulate regeneration of cells (hepatocytes).
  • Barley grass juice 24:1 extract, which enhances the enzyme aldehyde dehydrogenase, thus inhibiting the formation of acetaldehyde malondialdehyde.Taking the proper supplements before and after drinking can substantially mitigate hangover effects experienced by people suffering from acute alcohol toxicity.

Vitamin D May Cut Risk of Flu

Vitamin D may reduce the incidence and severity of influenza and other infections of the upper respiratory tract, new research means.
Simple steps such as eating supplements rich with vitamin D and getting more sunshine may help to reduce your chances of contracting flu and other similar diseasees, shows a study by scientists at Yale University School of treatment and Greenwich hospital in Connecticut.

“People in the South and West get more sun than in the North, which is good for them, because you get vitamin D from the sun,” study researcher James R. Sabetta, MD, of the Yale University School of treatment and Greenwich hospital, Conn., tells WebMD. “It’s not a panacea, but it helps.”

Sabetta and his team of colleagues followed 198 healthy adults during the fall and winter of 2009-2010 to see if declining levels of vitamin D in the fall and winter could be a factor in the seasonal increased prevalence of respiratory viral infections, such as flu.

The study shows people who maintain vitamin D blood levels of 38 nanograms per milliliter or more are less likely to get viral infections such as flu than people with less in their blood.

Of 18 people who maintained that level during the study period, only three developed viral infections.

But of the 180 other participants with less vitamin D in their blood, 81(45%), did get sick with viral infections.

And those with higher levels of vitamin D as well experienced a marked reduction in the number of days they were ill, Sabetta tells WebMD.

In addition to getting more sun and consuming milk and supplements with vitamin D, he recommends supplements, especially for people in areas with less sunlight and for those who spend daylight hours in darker, indoor surroundingss.

“If you have a level of 38, your risk is down 50%,” he tells WebMD. “A lot of people don’t have an adequate level, and 38 is a little on top of what you should have to be admit as true tdetested in the sufficient range. There are a billion people worldwide with levels below 30.”

And 30 is admit as true tdetested “sufficient,” he says.

Symptoms of disease

Participants in the study had blood samples drawn monthly using a sophisticated technique to exactly measure vitamin D levels. They didn’t know that vitamin D was being measured, and even investigators didn’t know until the end of the study.

All participants were asked to report symptoms of disease, such as nasal congestion, sore throat, cough with or without fever, chills, fatigue and general malaise.

Those reporting any symptoms were seen the same day at the study site by one of the infectious disease investigators.

People in the study kept a diary of symptoms and were called every one to three days during the disease to review any symptoms of symptoms until they were better. The investigators recorded the duration of each symptom, the total duration of the disease, and any antimicrobials administered.

Sabetta says the discoverings suggest that supplementing vitamin D to achieve a blood level of 38 nanograms per milliliter or higher could result in a considerable health benefit by reducing odds of contracting viral infections of the respiratory tract.

But he says more studies are needed to determine the efficacy of vitamin D supplementation in the prevention of infections, including influenza.

The researchers conclude that the lower levels of vitamin D seen during the winter in temperate climates may contribute to the prevalence of influenza in colder months.

The discoverings, Sabetta says, have considerable implications for public health and as well may make clear the seasonality of certain infections, and as well the higher morbidity and mortality of such diseasees in people who are predisposed to lower concentrations of vitamin D.

Sabetta says vitamin D has known effects on the immune system, and the study reinforces the association between vitamin D deficiency and susceptibility to infections of the respiratory tract.

The study is published online in the journal Plos ONE.

Vitamin D levels depend “on how big you are, your skin color, your diet and how much sun exposure you get,” Sabetta tells WebMD. “Individuals should get their vitamin D levels checked. If you are gardening a lot, you probably are fine, but people in an office all day may need supplements.”
