The Vitamin That Quadruples Weight Loss

Taking vitamin D supplements can significantly increase weight loss, according to a recent study.

People who took vitamin D supplements had over four times the weight loss as those that did not, researchers found.

obese

Vitamin D also doubled the number of inches taken off their waistlines.

Low levels of vitamin D is repeatedly linked to being overweight and obese.

Almost 40 percent of obese people are deficient in vitamin D.

The study included 400 obese and overweight people with vitamin D deficiency.

They were put on a low-calorie diet and split into three groups.

One group took 25,000 IU of vitamin D per month, the second took 100,000 IU of vitamin D per month and the control group took none.

Six months later the results showed that both vitamin D groups had lost more weight than those who were not taking the vitamin.

Those taking 100,000, or around 3,000 IU per day, had 12 pounds of weight loss.

People taking 25,000 IU, or around 800 IU per day, lost 8 pounds.

In comparison, those only following the calorie restricted diet had just 2.6 pounds of weight loss over the six months.

The study’s authors write:

“The present data indicate that in obese and overweight people with vitamin D deficiency, vitamin D supplementation aids weight loss and enhances the beneficial effects of a reduced-calorie diet.”

Measurements of dieters’ waistlines also revealed vitamin D had had an effect.

Those taking 100,000 IU lost an average of two inches from their waistline compared to just over 1 inch in the control group.

The researchers conclude:

“All people affected by obesity should have their levels of vitamin D tested to see if they are deficient, and if so, begin taking supplements.”

Gut Bacteria is Key Factor in Childhood Obesity



Summary:
Scientists suggest that gut bacteria and its interactions with immune cells and metabolic organs, including fat tissue, play a key role in childhood obesity.


New information published by scientists at Wake Forest Baptist Health suggests that gut bacteria and its interactions with immune cells and metabolic organs, including fat tissue, play a key role in childhood obesity.

“The medical community used to think that obesity was a result of consuming too many calories. However, a series of studies over the past decade has confirmed that the microbes living in our gut are not only associated with obesity but also are one of the causes,” said Hariom Yadav, Ph.D., lead author of the review and assistant professor of molecular medicine at Wake Forest School of Medicine, part of Wake Forest Baptist.

In the United States, the percentage of children and adolescents affected by obesity has more than tripled since the 1970s, according to the Centers for Disease Control and Prevention. Obesity is increasing at 2.3% rate each year among school-aged children, which is unacceptably high and indicates worrisome prospects for the next generation’s health, the article states.


Yadav’s manuscript, published in the current issue of the journal Obesity Reviews, reviewed existing studies (animal and human) on how the interaction between gut microbiome and immune cells can be passed from mother to baby as early as gestation and can contribute to childhood obesity.


The review also described how a mother’s health, diet, exercise level, antibiotic use, birth method (natural or cesarean), and feeding method (formula or breast milk) can affect the risk of obesity in her children.

“This compilation of current research should be very useful for doctors, nutritionists and dietitians to discuss with their patients because so many of these factors can be changed if people have enough good information,” Yadav said. “We also wanted to identify gaps in the science for future research.”

In addition, having a better understanding of the role of the gut microbiome and obesity in both mothers and their children hopefully will help scientists design more successful preventive and therapeutic strategies to check the rise of obesity in children, he said.

What Is Folic Acid, Why Do You Need It And What Foods Have It?

What Is Folic Acid?

Folic acid is the synthetic version of the folate, a B vitamin that’s vital for the formation of red blood cells. It also plays a part in helping the body’s nerves function properly. The vitamin is essential in helping DNA form within cells, “allowing each cell to replicate perfectly”, according to the BDA, the association of British dieticians.

If you don’t have enough folic acid in your body, it can cause a form of anaemia – where blood cells have reduced ability to carry oxygen around the body – which causes tiredness, weakness and fatigue. People with a deficiency might also suffer from diarrhoea, loss of appetite, weight loss, headaches, heart palpitations, a sore tongue and behavioural disorders.

Why Is It Important For Pregnant Women?

Folic acid fortification – the process of folic acid being added to grain products – has already been adopted in more than 60 countries worldwide, including Australia, Canada and the US.

The government’s 12-week consultation on whether folic acid should be added to flour follows years of campaigning by charities including Shine, which represents people with the birth defect spina bifida.

Pregnant women are advised to take a folic acid supplement before conceiving and for the first 12 weeks of pregnancy to cut the risk of birth defects. But some women forget to take the supplement, do not follow advice or do not discover they are pregnant until it is too late.

Neural tube defects (NTDs) – birth defects of the brain, spine or spinal cord – occur when an opening in the spinal cord or brain remains from early on in human development. “Folic acid can prevent NTDs, but only if taken very early in the pregnancy, and really before conception,” says Clare Murphy, director of external affairs at Bpas.

“Currently, women are advised to take folic acid supplements during the early stages of pregnancy, but around half of UK pregnancies are unplanned, which means that many women have already missed the window to take folic acid by the time they realise they are pregnant.”

Around 1,000 pregnancies are affected by NTDs each year in the UK and more than 40% of cases are fatal. Under plans to fortify flour, experts predict that around 200 birth defects a year could be prevented.

Public health minister Seema Kennedy said the move would also help women from the poorest areas who are less likely to take folic acid supplements. “It is right that we do all we can to protect the most vulnerable in society,” she added.

 

Do Men Need It Too?

Folic acid is important for everyone, regardless of their sex. According to the BDA, men, children and women who are not likely to become pregnant should be able get sufficient amounts of folate (the form of folic acid occurring naturally in food) by eating a healthy diet.

It’s been reported that folic acid can help protect the heart and cardiovascular system, boost sperm count, and decrease the risk for certain cancers. Some evidence suggests it might even reduce the risk of mood disorders.

What Foods Contain Folate (Folic Acid)?

  • Spinach
  • Kale
  • Brussels sprouts
  • Cabbage
  • Broccoli
  • Beans and legumes (ie. peas, blackeye beans)
  • Yeast and beef extracts
  • Oranges and orange juice
  • Wheat bran and other whole grain foods
  • Poultry
  • Pork
  • Shellfish
  • Liver
  • Fortified foods (ie. some brands of breakfast cereals – check the label).

How Much Should You Have?

Adults and children over 11 years old are recommended to have 200μg (micrograms) of folate daily, according to the BDA. You can get enough folic acid from food alone – many cereals have 100% of your recommended daily value of folic acid. Look on the outside of packets for the nutritional chart or the ‘contains folic acid’ symbol.

Women trying for a baby are advised to have 200μg plus a supplement. For pregnant women, the advice is to take 300μg plus a 400μg supplement during the first 12 weeks of pregnancy – but consult your doctor first, especially if you’ve had a pregnancy previously affected by neural tube defects or if you have diabetes.

Breastfeeding mothers are advised to make sure they’re having 260μg a day, to help their child’s development.

Should You Take Folic Acid Supplements?

While pregnant women are strongly advised to take folic acid supplements, the rest of the population should be able to get enough providing they eat a balanced, nutritious diet. BDA suggests those aged over 50, or those with a history of bowel cancer, should take no more than 200μg/day per day.

Potential side effects of taking additional supplements daily include nausea, loss of appetite, trapped wind or bloating – although the NHS notes these symptoms are usually mild and don’t last long.

If you have any of the following, you should speak to your doctor before having folic acid supplements:

  • An allergic reaction to folic acid or any other medicine
  • Low vitamin B12 levels or pernicious anaemia
  • Cancer
  • Kidney dialysis
  • A heart stent

Vitamin D Lowers Risk of Dying From Cancer, Fish Oil Reduces Heart Attack Risk: Study

A large U.S. study designed to gauge the health benefits of vitamin D and fish oil supplements concludes that the omega-3 oil can dramatically reduce the odds of a heart attack while vitamin D’s benefits seem to come from lowering the risk of death from cancer.

Neither vitamin D nor fish oil lowered the odds of stroke or of getting cancer in the first place in the trial, whose participants did not know whether they were taking the real supplements or a dummy pill.

The heart attack rate in fish oil recipients was 28 percent lower than among those who got the dummy pill, or placebo, and it was 77 percent lower among African American participants – although the lead author of the study told Reuters Health that this dramatic drop in risk among black participants needs to be confirmed.

For people taking vitamin D who developed cancer, the death rate from cancer was 25 percent lower, possibly because the vitamin “may affect the biology of the tumor so it’s less likely to spread and become metastatic,” said lead author Dr. JoAnn Manson, chief of the division of preventive medicine at Brigham and Women’s Hospital in Boston.

“If you’re talking about prevention of cancer, that may take treatment for well over a decade.”

It took a few years of vitamin D use for the reduction in cancer deaths to become clear.

The results were reported Saturday at the American Heart Association Scientific Sessions meeting in Chicago and online in the New England Journal of Medicine.

Both supplements have a reputation for being beneficial based on animal tests and observational studies involving large diverse populations or ethnic groups. But large studies that directly test the benefits of vitamin D and fish oil in supplement form have given inconsistent results.

The new study, known as VITAL, is the first large test of both in the general population. Most previous research has focused on volunteers with an elevated risk of heart attack, stroke and/or cancer.

vitamine d

The researchers gave 2,000 international units of vitamin D per day, 1 gram of marine omega-3 fatty acids, or placebo supplements to 25,871 volunteers aged 50 or older. None had a history of cancer, heart attack or stroke. At least half stayed in the study for more than five years.

Based on the new findings, “people already taking vitamin D or fish oil will feel there’s no reason to stop,” Manson said.

People who are considering starting the supplements may want to wait “because we are going to be publishing findings for other endpoints – diabetes, cognitive function, depression, autoimmune diseases – over the next six months,” she said. “These findings may help people decide if the benefits are likely to outweigh the risks for them.”

And people should not be taking higher doses than what was used in the study, Manson noted. With megadoses, “the risk may outweigh the benefit. With high doses of vitamin D there can be a risk of high blood calcium levels developing. Some have suggested a higher risk of cardiovascular disease, falls and even fractures.”

By other measures, neither supplement seemed useful.

Among fish oil recipients, the rates of death from any cause, death from cancer and death from heart disease in general were not significantly different than for people not taking fish oil supplements.

In addition, the collective odds of having a heart attack, stroke or death from any cardiovascular cause were essentially the same whether people were taking fish oil or placebo.

It was only when researchers teased out individual elements of heart disease – such as the rate of heart attack, the rate of fatal heart attack and the need for angioplasty – that a benefit stood out.

Even a little fish oil seemed to help. Volunteers who consumed less fish than average – less than one-and-a-half servings per week – and received the real omega-3 supplements saw a 40 percent reduction in the risk of a heart attack.

In the vitamin D study, which was “the largest high-dose randomized trial of vitamin D in the world,” according to Manson, supplement and non-supplement recipients had similar rates of heart attack, stroke, death from heart attack and cancers of the breast, prostate, or the colon and rectum.

It was only the odds of dying from cancer that were reduced.

Could a Daily Vitamin Curb Smog’s Health Effects?

Small study suggests vitamin B might help, but reducing pollution levels remains the priority

There’s a lot of evidence to show that breathing in dirty air can harm your heart. But a small new study suggests that daily vitamin B supplements might counteract that effect.

While two hours of exposure to concentrated air pollution had a negative effect on heart rate and levels of illness-fighting white blood cells, “these effects are nearly reversed with four-week B-vitamin supplementation,” according to study co-author Dr. Andrea Baccarelli. He’s chair of environmental health sciences at Columbia University in New York City.

One lung health expert was cautiously optimistic about the findings.

“It is interesting that pretreating with B vitamins may prevent some of the deleterious effects of exposure to this pollution,” said Dr. Alan Mensch, senior vice president of medical affairs at Northwell Heath’s Plainview Hospital in Plainview, N.Y.
“It must be kept in mind, however, that since this study only included 10 healthy patients, it might not be applicable to an entire population,” he added. Plus, preventing air pollution in the first place “takes precedent over developing methods to prevent its deleterious effects,” he said.

The new research involved 10 healthy nonsmokers, aged 18 to 60, who took a placebo for four weeks before being exposed to fine-particulate air pollution for two hours.

The “fine particulates” – microscopic specks – were 2.5 micrometers in diameter, the researchers said.

Inhalable particles that are “2.5 micrometers or smaller are potentially the most dangerous form of air pollution due to their ability to penetrate deep in the lungs and adjacent bloodstream,” Mensch explained. Once inhaled, “they can travel to various organs throughout the body,” he added, causing inflammation and ill effects on cardiovascular health.

“Populations exposed to high particulate-associated air pollution have increased heart attacks, lung cancer, DNA mutations, and premature births and deaths,” Mensch said.

Overall, fine-particle pollution contributes to 3.7 million premature deaths worldwide each year, mainly through harm to the cardiovascular system. This type of air pollution is believed to be the most common trigger for heart attack, the study authors noted.

But could a simple daily vitamin supplement help curb this smog-linked damage?

To find out, Baccarelli’s group gave the 10 participants vitamin B supplements for four weeks before again exposing them to the fine-particle air pollution for another two hours.

This time, the vitamin B supplements were linked to a near-reversal of the negative effects of the pollution on the volunteers’ cardiovascular and immune systems, the researchers said. This included healthy changes in each person’s heart rate and their white blood cell levels.

Baccarelli stressed that preventing pollution should always be the first measure in safeguarding people’s health, however.

“Pollution regulation remains the backbone of public health protection against its cardiovascular health effects,” he said in a university news release. “Studies like ours cannot diminish — nor be used to underemphasize — the urgent need to lower air pollution levels to — at a minimum — meet the air-quality standards set forth in the United States and other countries.”

Another lung expert agreed that the vitamin supplements could help blunt the health effects of dirty air.

The new study is “evidence that vitamin B provides benefits against the development of atherosclerosis in healthy adults who are exposed to air pollution,” said Dr. Len Horovitz, a pulmonary specialist at Lenox Hill Hospital in New York City.

While it remains unclear just how the supplement works in this regard, “this finding recommends vitamin B, which is of course safe and has no side effects, as a buffer against coronary artery disease,” Horovitz said.

The study was published online recently in the journal Scientific Reports.

Link Between Vitamin D Treatment and Autism Prevention

Giving vitamin D supplements to mice during pregnancy prevents autism traits in their offspring, researchers have discovered. The discovery provides further evidence of the crucial role vitamin D plays in brain development.

In human studies, researchers recently found a link between pregnant women with low Vitamin D levels and the increased likelihood of having a child with autistic traits.

Giving vitamin D supplements to mice during pregnancy prevents autism traits in their offspring, University of Queensland researchers have discovered.

The discovery provides further evidence of the crucial role vitamin D plays in brain development, said lead researcher Professor Darryl Eyles, from UQ’s Queensland Brain Institute.

“Our study used the most widely accepted developmental model of autism in which affected mice behave abnormally and show deficits in social interaction, basic learning and stereotyped behaviours,” Professor Eyles said.

“We found that pregnant females treated with active vitamin D in the equivalent of the first trimester of pregnancy produced offspring that did not develop these deficits.”

In human studies, QBI researchers recently found a link between pregnant women with low Vitamin D levels and the increased likelihood of having a child with autistic traits.

Autism – or autism spectrum disorder – describes lifelong developmental disabilities including difficulty or inability to communicate with others and interact socially.

Sun exposure is the major source of vitamin D – which skin cells manufacture in response to UV rays – but it is also found in some foods.

Dr Wei Luan, a postdoctoral researcher involved in the study, said vitamin D was crucial for maintaining healthy bones, but the active hormonal form of vitamin D cannot be given to pregnant women because it may affect the skeleton of the developing fetus.

“Recent funding will now allow us to determine how much cholecalciferol – the supplement form that is safe for pregnant women – is needed to achieve the same levels of active hormonal vitamin D in the bloodstream,” said Dr Luan.

This new information will allow us to further investigate the ideal dose and timing of vitamin D supplementation for pregnant women.

It was previously thought vitamin D had a protective anti-inflammatory effect during brain development, but the study didn’t find this to be the case.

New funding from the National Health and Medical Research Council will allow researchers to continue to study how vitamin D protects against autism.

Vitamin D Can Protect Against Colds, Flu, Study Suggests

Taking extra vitamin D can protect against colds, flu and other respiratory infections, said a study Thursday which reopened a debate on the usefulness of over-the-counter supplements.

A review of 25 clinical trials in 14 countries, some with conflicting results, yielded “the first definitive evidence” of a link between vitamin D and flu prevention, researchers claimed in The BMJ medical journal.

The effects were strongest for people with very low levels of the nutrient which is found in some foods and can be synthesised by the body when the skin is exposed to ultraviolet light.

Many people, especially in grey, cloudy climes, do not have enough vitamin D.

Scientific studies over the years have delivered contradictory conclusions on the topic.

Some have shown that low levels of the vitamin increase the risk of bone fractures, heart disease, colorectal cancer, diabetes, depression, Alzheimer’s disease and death.

Others said there is no evidence of a link to disease risk.

For the new study, researchers from the Queen Mary University of London conducted the biggest-ever survey of trials involving nearly 11,000 people.

Vitamin D is found in some foods and can be synthesized
by the body when the skin is exposed to ultraviolet light.

And they found clues as to why supplements seem to work in some trials but not in others.

“The bottom line is that the protective effects of vitamin D supplementation are strongest in those who have the lowest vitamin D levels, and when supplementation is given daily or weekly rather than in more widely-spaced doses,” lead researcher Adrian Martineau said in a statement.

‘Undeniable’

Vitamin D is thought to protect against respiratory infections, including bronchitis and pneumonia, by boosting levels of antibiotic-like peptides in the lungs, said the team.

This fits with an observation that colds and flu are more common in winter and spring, when vitamin D levels are lowest.

It may also explain why vitamin D seems to protect against asthma attacks, they said.

In an editorial published with the study, experts Mark Bolland and Alison Avenell said it should be viewed as a hypothesis in need of scientific confirmation.

Louis Levy, head of nutrition science at Public Health England, shared their caution.

“This study does not provide sufficient evidence to support recommending vitamin D for reducing the risk of respiratory tract infections,” he said via the Science Media Centre in London.

Other observers were more optimistic.

The case for universal vitamin D supplements, or food fortification, “is now undeniable,” concluded Benjamin Jacobs of the Royal National Orthopaedic Hospital.

B Vitamins Cut Lung Cancer Risk in Half

Lung cancer is the most common cause of death from cancer in the world today. A 2010 study revealed how improving your intake of B vitamins could reduce your risk of developing this disease by 50 percent or more.

The study, published in the Journal of the American Medical Association, gathered information about the diet and lifestyle of over 385,000 people in several European countries between 1992 and 2000.

Blood samples were taken at the start of the study and analyzed for levels of B vitamins and related biochemicals, such as methionine, an essential amino acid your body doesn’t produce on its own. Methionine must be consumed in your diet.

These nutrients were studied because they are known to help the synthesis and repair of DNA in the body’s tissues, potentially preventing defects in DNA that can cause cancer.

It was found that the risk of developing lung cancer was reduced by at least 50 percent in people who had high levels of vitamin B6 and methionine. When the B vitamin folate was also present, it cut lung cancer risk by 66 percent.

The study participants had been broken into groups of people who had never smoked, formerly smoked and currently smoked. Interestingly, the risk of developing lung cancer was reduced by the same amounts in all groups.

Researchers were quick to point out that even though B vitamins reduce the risk of developing lung cancer for smokers, this does not detract from the importance of reducing the use of tobacco throughout the world. Smoking is still the number one cause of lung cancer and should be prevented.

It was also noted that long term consumption of adequate B vitamins appears to provide the most benefit and protection against cancer. There is no evidence that short-term doses of B vitamins would be protective.

B vitamin deficiencies tend to be high in many western populations. It’s important to make sure you’re consuming enough B vitamins on an ongoing basis.

How to Get More B Vitamins

Supplements are an easy way to boost your B vitamin intake. B-complex vitamin supplements contain all eight of the known B vitamins. You can also get supplements with one or more of the individual B vitamins, such as B6.

Food may be the best way to get your B vitamins because foods rich in B vitamins are also often packed with other vital nutrients. B vitamins tend to be found in most whole, unprocessed foods.

Excellent sources of B vitamins in general include:

  • Leafy green vegetables
  • Starchy vegetables, such as squash, potatoes and parsnips
  • Animal products, including meat, dairy, and eggs
  • Fruits, such as avocado, dates and berries
  • Legumes, including tempeh and tofu
  • Nuts and seeds
  • Whole grains
  • Nutritional yeast
  • Molasses

Foods high in specifically vitamin B6 include fish, organ meats, starchy vegetables and fruit (other than citrus). Chick peas are also a great source of B6, with a one cup serving providing 55 percent of your daily recommended intake.

The amino acid methionine is available as a supplement. In food, it is primarily found in animal products like fish and red meats, as well as dairy and eggs.

Good vegan sources of methionine include spirulina, sesame seeds, soy products, peanuts and lentils. Smaller amounts are also found in many fruits and vegetables, such as broccoli, spinach, sweet corn, cauliflower and asparagus.
