Scientifically-Designed Fasting Diet Lowers Risks for Major Diseases

TEHRAN (FNA)- Results of a randomized clinical trial shows a periodic, five-day fasting diet designed by a researcher safely reduced the risk factors for heart disease, cancer, diabetes and other age-related diseases.

That's what happened for 71 adults who were placed on three cycles of a low-calorie, "fasting-mimicking" diet. The phase II trial, conducted by researchers at the USC Leonard Davis School of Gerontology, demonstrated a host of benefits from the regimen.

The diet reduced cardiovascular risk factors including blood pressure, signs of inflammation (measured by C-reactive protein levels), as well as fasting glucose and reduced levels of IGF-1, a hormone that affects metabolism. It also shrank waistlines and resulted in weight loss, both in total body fat and trunk fat, but not in muscle mass.

In effect, the diet reduced the study participants' risks for cancer, diabetes, heart disease and other age-related diseases, according to the findings published Feb. 15 in Science Translational Medicine.

"This study provides evidence that people can experience significant health benefits through a periodic, fasting-mimicking diet that is designed to act on the aging process," said Valter Longo, director of the USC Longevity Institute and a professor of biological sciences for USC Davis and Dornsife. "Prior studies have indicated a range of health benefits in mice, but this is the first randomized clinical trial with enough participants to demonstrate that the diet is feasible, effective and safe for humans.

"Larger FDA studies are necessary to confirm its effects on disease prevention and treatment," he added.

One hundred people participated in the trial from April 2013 to July 2015. The participants, ages 20 to 70 and all generally healthy, were divided into two groups for the randomized trial.

Participants in the first group, the control group, were asked to continue their normal eating habits for three months. People in the second group were placed on a three-month test of the fasting-mimicking diet.

Those on the special diet were required to eat food products supplied by the nutrition company L-Nutra during the fasting periods of five days each month. The diet, which was designed to mimic the results of a water-only fast, allowed for participants to consume between 750 and 1,100 calories per day. The meals for the fast-mimicking diet contained precise proportions of proteins, fats and carbohydrates.

After three months, participants in the control group were moved onto the special diet.

The researchers found that participants on the fasting-mimicking diet lost an average of about 6 pounds. Their waistlines shrank by 1 to 2 inches. Their systolic blood pressure, which was in the normal range when the study began, dropped by 4.5 mmHG, while their diastolic blood pressure dropped by 3.1 mmHg. Also, their levels of IGF-1 dropped to between 21.7 ng/mL and 46.2 ng/mL, reaching a range associated with lower cancer risk.

"After the first group completed their three months on the fasting diet, we moved over participants in the control group to see if they also would experience similar results," Longo said. "We saw similar outcomes, which provides further evidence that a fasting-mimicking diet has effects on many metabolic and disease markers. Our mouse studies using a similar fasting-mimicking diet indicate that these beneficial effects are caused by multi-system regeneration and rejuvenation in the body at the cellular and organ levels.

"Our participants retained those effects, even when they returned to their normal daily eating habits," he added.

The researchers also noted that participants considered "at risk" because they had risk factors such as high IGF-1, cholesterol, blood pressure or blood sugar levels, made significant progress toward better health.

For example, baseline fasting glucose levels for participants with high blood sugar levels (putting them at risk for diabetes) dropped into the healthy range, below 99 mg/dl -- but these levels didn't drop among participants who already had healthy levels at the beginning of the study. Cholesterol was reduced by 20 mg/dl in those with high cholesterol levels, and by about 5 mg/dl in all participants.

"Fasting seems to be the most beneficial for patients who have the great risk factors for disease, such as those who have high blood pressure or pre-diabetes or who are obese," Longo said.

The researchers had invited participants in the study for one last set of tests three months later, at the end of the diet. The research team found that the beneficial effects -- from weight loss, smaller waistlines and lower glucose, blood pressure and IGF-1 levels -- were sustained.

The next step for researchers is a large, FDA phase III clinical trial to test the FMD on patients diagnosed with age-related diseases or at high risk for them. The researchers said further investigation will determine whether the benefits of the diet can continue for several months.

ロシアが一時的にNZ産牛肉の輸入を停止 筋肉増強剤ラクトパミン検出のため

Russia issues temporary ban on beef from New Zealand
The Russian agriculture safety watchdog has imposed a temporary ban on imports of beef and beef products from New Zealand, effective February 6.

“The measure comes after the feed additive Ractopamine, a stimulant fertilizer for promoting muscle growth, has been discovered in some samples,” the watchdog spokesperson said.

The watchdog also said that it might ban fish imports from New Zealand due to traces of mercury in some supplies.

New Zealand is not one of the Western countries facing a Russian food ban. Moscow introduced the measure in 2014 in response to sanctions imposed by the US, EU and their allies over Russia’s alleged role in the Ukraine crisis.

The ban Russia plans to impose on the beef would be disruptive because of the uncertainty, but it's the reality of being in the food business, Special Agricultural Trade Envoy Mike Petersen told Radio New Zealand.

The ban would not affect the country's trade relationship with Moscow, Petersen said, adding that further testing would show beef from New Zealand was clean.

The additive Ractopamine is not registered in New Zealand for use in beef cattle, according to the spokesperson for the country’s Ministry for Primary Industries.

“New Zealand food standards are among the highest in the world, and we are committed to producing high-quality, safe meat for domestic and overseas consumers,” the spokesman said.

The stimulant is allowed in pork feed in New Zealand but is prohibited in beef or sheep, according to Tim Ritchie, chief executive of the Meat Industry Association (MPI).

“As far as I'm aware there has been no formal communication through the normal regulatory channels,” he said, stressing that the MPI launched a residues projects with the last report showed no Ractopamine had been picked up.

Russian watchdog Rosselkhoznadzor said it had asked New Zealand’s authorities to hold consultations on the issue.

Dying younger: US life expectancy trending downward - study

Life expectancy for Americans aged 25 to 85 is getting shorter, according to a new study. For 65-year-old males and females, expected lifespan has fallen by six months compared to projections in 2015, the study found.

The Society of Actuaries (SOA) released its latest annual mortality improvement scale for pension plans earlier this month. The scale is crafted using Social Security Administration data from 2012 to 2014 on mortality of Americans of all ages, and is used by pension plans to "help accurately measure pension obligations,"said Dale Hall, SOA's managing director of research.

"The updated improvement scale suggests US mortality continues to improve, but at a slower average rate of improvement than previous years, which may decrease pension plan obligations slightly," SOA said, adding that the "updated improvement scale indicates a slight decline in life expectancy as a result of the slower average rate of mortality improvement."

For example, in 2015, the average 65-year-old American male was expected to live to 86.2, while the average female of the same age was expected to live to 88.2. New projections by the SOA posit that life expectancy for 65-year-old males is more like 85.8, and 87.8 for females of the same age.

SOA's calculations are made with an assumption that Americans' longevity will continue to improve. And while the average millennial that reaches age 65 is expected to live a few more years than the average baby boomer, life expectancy is getting shorter for younger Americans as well, the study found.

Life expectancy for female Americans ages 25 to 55 went down by 0.6 years – same as males ages 45 to 65 – while males in the 25-55 age bracket were down by 0.7 years. Americans ages 75 and 85 also saw decreases in life expectancy projections, but less so than younger age groups.

In June, the US Centers for Disease Control and Prevention (CDC) reported that 2015 marked the first time in ten years that the American death rate had increased. Unlike trends for other age, racial, and ethnic groups in America, the death rate for middle-aged white Americans is rising, according to a Princeton study released in November 2015. Furthermore, the suicide rate in the US spiked by 24 percent from 1999 to 2014, according to the federal government.

One in three Americans is obese, the CDC said in September 2015. The agency also found that one in three children and teens in America eat fast food daily. Meanwhile, the maternal mortality rate in the US is on par with nations such as Palestine and Libya, according to a study released earlier this month.

低糖質・高脂質ダイエット ちょっと怖いが効くだろうか

英国の優れた心臓専門医 ASEEM MALHOTRA氏によるDaily Mail紙への寄稿の概訳

元記事:DailyMail 2016/7/2
Eating MORE fat while cutting carbs and quitting sugar can help you lose weight and be happier, says top cardiologist


英国 Harefield病院の心臓専門医の研修医として勤務していた2010年当時、私(ASEEM MALHOTRA医師。以下同じ。)は、緊急の手術を要するほど進行した心疾患の患者を担当。朝の診察を行っていた際に病院の朝食を見たところ、糖質たっぷりのシリアル、トースト、たっぷりのジャムとマーマレードが出されていた。そもそも、このような食事がこの心臓病を悪化させるようなものなのに。










英国よりも肥満等が深刻な米国では、一足早く米国心臓協会(American Heart Association)が2009年に機関紙で糖質の摂取の危険性と、1日の摂取量の上限として男性は小さじ9杯、女性は6杯と発表した。

英国では、1日の摂取量の上限は小さじ22杯とされており、これに愕然とした私は、自らこれまでの常識を打ち破る低糖質・高脂質ダイエット(low-carb, high fat diet。以下「LCHFダイエット」という。)を敢行。























2012年のロンドンオリンピックのスポンサーは、コカコーラ社にマクドナルド社であり、英国栄養基金(British Nutrition Foundation)の会員は、砂糖産業であるコカコーラ社、ケロッグ社、マクドナルド社、ネッスル社とペプシ社であり、英国栄養士会(British Dietetic Association)は、バランスのとれた食事の一環としてフルーツジュースを推奨しており、それは当面変わりそうにない。

しかし、これは変えねばならない。私は、LCHFダイエットが長寿に資することを説明したドキュメンタリー「The Big Fat Fix(多量の脂質が健康問題を解決)」を共同プロデュースし、数週間後に公開される予定である。これが奏功することを希望する。



来週には、Karen Thomsonの最新刊「Sugar Free」には、美味なレシピ本が発行される。
LCHF仕様に食生活を変化させるということは、糖分とでんぷん質 (全粒粉、シリアル、パン、パスタ、米、ジャガイモ等) を制限し、健康に良い脂質の摂取を増やし、適切な量のタンパク質(魚、肉、卵、乳製品)を摂取することである。

Genetically modified wheat was found growing in a Washington state field, according to agricultural officials. Regulatory agencies haven’t approved GMO wheat for production in the US, and the discovery could affect wheat sales abroad.

Federal authorities said on Friday that a farmer had discovered 22 herbicide-resistant wheat plants growing in an unplanted field, as first reported by the Associated Press.

The GMO wheat was developed to be resistant to the herbicide Roundup, which was created by the seed giant Monsanto. The US Department of Agriculture (USDA) said it is holding and testing the farmer’s entire wheat harvest, but so far has not found any more GMOs.

The agency added there has been “no evidence of GE wheat in commerce."

Genetically modified wheat is banned for sale or production in the US, and it is not clear how the genetically engineered wheat ended up in Washington.

Monsanto said in a statement that the discovered wheat had been used in limited field trials in the Pacific Northwest from 1998 to 2001, but was never commercialized, noting that its DNA matched strains found in Oregon three years ago.

The farmer’s discovery could impact US wheat trade overseas, where many countries are concerned about the possible safety risks associated with genetically engineered food, with some imposing outright bans on it.

On Friday, South Korea suspended customs clearance for some genetically altered wheat from the United States due to safety concerns, while announcing that the distribution and sale of US wheat will also be halted, according to the Yonhap News Agency

The unapproved genetically modified wheat discovered in Oregon in the spring of 2013 led to worldwide testing of shipments arriving in the European Union and South Korea. China and the Philippines said they would monitor the situation at the time, while Japan stopped importing completely.

The USDA, which closed its investigation after two years, was never able to say how the wheat got there.

In 2014, genetically modified wheat plants were found at a university research center in Montana, where it had been legally tested by Monsanto in the early 2000s.

Asia imports more than 40 million metric tons of wheat annually, almost a third of the global trade, with the bulk of the region’s supply coming from the US.

The USDA has validated a test for Monsanto’s herbicide-resistant wheat available to trading partners and beefed up oversight on engineered field trials, which now require developers to apply for a permit if they involve GMO wheat, starting this year.

The US government has approved genetically engineered crops such as corn and soybeans designated for livestock, and approved their conversion into cornstarch, soybean oil, and high fructose corn syrup, which are used in many popular processed foods.

The Food and Drug Administration recently approved a genetically engineered salmon that will grow faster than a natural one, but it is not yet available for consumption.

B Vitamins in Promote Stem Cell Proliferation

TEHRAN (FNA)- Folates can stimulate stem cell proliferation independently of their role as vitamins, according to a new study that used an in vitro culture and animal model system in their findings.

Folates, whether supplemental B vitamins or natural folates found in food, are essential for the proper functioning of all cells in the body and are critical to prevent birth defects.

The study in Developmental Cell, shows for the first time that an adult stem cell population is controlled by an external factor arising from outside the animal--bacterial folate. In this case, that animal was a small roundworm model organism known as Caenorhabditis elegans.

"Our study shows that germ stem cells in Caenorhabditis elegans are stimulated to divide by a specific folate that comes from their bacterial diet," said the study's co-senior author Edward Kipreos, a professor in UGA's Franklin College of Arts and Sciences. "Folates are essential B-group vitamins. However, we show that the ability of a specific folate to stimulate germ cells is independent of its role as a vitamin, implying that it acts directly as a signaling molecule."

Naturally occurring folates exist in many chemical forms; folates are found in food, as well as in metabolically active forms in the human body. Folic acid is the major synthetic form found in fortified foods and vitamin supplements.

"Since its discovery in 1945, folate has been the subject of many studies that resulted in more than 50,000 publications. The finding in this study is the first of its kind because it presents evidence that folate is involved in roles other than those that were known before," said the study's co-senior author Jacob Selhub, director of the Vitamin Metabolism Laboratory at Tufts University.

Eating Red Meat May Bring On Kidney Failure

TEHRAN (FNA)- Red meat intake was strongly associated with an increased risk of kidney failure among Chinese adults in Singapore who were followed for an average of 15.5 years, a new report suggests. No association was found with intakes of poultry, fish, eggs, or dairy products, while soy and legumes appeared to be slightly protective.

Increasing numbers of individuals are developing chronic kidney disease (CKD), and many progress to end-stage renal disease (ESRD), which requires dialysis or a kidney transplant. Current guidelines recommend restricting dietary protein intake to help manage CKD and slow progression to ESRD; however, there is limited evidence that overall dietary protein restriction or limiting specific food sources of protein intake may slow kidney function decline in the general population.

To examine the relationship between dietary intake of major sources of protein and kidney function, a team led by Woon-Puay Koh, MBBS (Hons), PhD (Duke-NUS Medical School and Saw Swee Hock School of Public Health in National University of Singapore) analyzed data from the Singapore Chinese Health Study, a prospective study of 63,257 Chinese adults in Singapore. This is a population where 97% of red meat intake consisted of pork. Other food sources of protein included poultry, fish/shellfish, eggs, dairy products, soy, and legumes.

After an average follow-up of 15.5 years, the researchers found that red meat intake was strongly associated with an increased risk of ESRD in a dose-dependent manner. People consuming the highest amounts (top 25%) of red meat had a 40% increased risk of developing ESRD compared with people consuming the lowest amounts (lowest 25%) No association was found with intakes of poultry, fish, eggs, or dairy products, while soy and legumes appeared to be slightly protective. Substituting one serving of red meat with other sources of protein reduced the risk of ESRD by up to 62%.

"We embarked on our study to see what advice should be given to CKD patients or to the general population worried about their kidney health regarding types or sources of protein intake," said Dr. Koh. "Our findings suggest that these individuals can still maintain protein intake but consider switching to plant-based sources; however, if they still choose to eat meat, fish/shellfish and poultry are better alternatives to red meat."

Ibuprofen & other common drugs, supplements may cause, exacerbate heart failure – study

Commonly-prescribed and -used medications, such as Ibuprofen, and nutritional or natural supplements may trigger or worsen heart failure, according to a new statement released by the American Heart Association.

The statement identifies drugs, supplements, and alternative remedies that "may cause or exacerbate heart failure" when taken with other medications or taken to treat certain conditions, the American Heart Association (AHA) said in a scientific statement released Monday on the website of the AHA journal Circulation.

Patients with heart failure, the leading cause of hospitalization for people 65 years of age and older, should discuss in detail with their healthcare provider every prescription, over-the-counter medication, nutritional supplement, or natural remedy, such as an herb, that they ingest, said Robert L. Page II, chair of the committee that formulated the statement.

“Since many of the drugs heart failure patients are taking are prescribed for conditions such as cancer, neurological conditions or infections, it is crucial but difficult for healthcare providers to reconcile whether a medication is interacting with heart failure drugs or making heart failure worse,”said Page.

For example, common heartburn medications or cold remedies can come with high levels of sodium, which can be detrimental to patients with heart failure conditions, the AHA said.

“Patients have been taught to read food labels for sodium content, but they also need to read labels on over-the-counter medications and natural supplements,” said Page.

Heart failure patients take an average of seven prescription medications per day, Reuters reported.

Certain medications can be toxic to heart muscle cells or alter how the heart muscle contracts, the AHA said, or interact with heart failure medications in a way that ultimately negates their benefits.

Heart failure is defined by the US Centers for Disease Control and Prevention as a condition in which "the heart cannot pump enough blood and oxygen to support other organs in your body." Nearly 6 million adults in the US have heart failure, the CDC says, and one in nine deaths in 2009 included heart failure among its contributing conditions.

Around half of people who are identified as having conditions of heart failure die within five years of diagnosis, the CDC says.

Supplements that contain ephedra can cause a spike in blood pressure, while other complementary or alternative supplements − such as St. John’s wort, ginseng, hawthorn, danshen, and green tea − can interfere with some common heart failure medications, the AHA said.

“My hope is that this statement will be used by healthcare providers in all medical specialties to educate themselves about drugs that can exacerbate or cause heart failure,” said Page, a professor in the Department of Clinical Pharmacy and the Department of Physical Medicine/Rehabilitation at the University of Colorado Schools of Pharmacy and Medicine.

Nobel laureates to Greenpeace: ‘Abandon your campaign against GMOs’

Over 100 Nobel laureates have signed a letter asking Greenpeace to halt its campaign against genetically modified crops and feeds, especially Golden Rice. They argue that GMOs can offer life-saving food sources to the world’s poorest regions.

The group is holding a news conference on Thursday to discuss the topic at the National Press Club in Washington DC on Thursday.

“WE CALL UPON GOVERNMENTS OF THE WORLD to reject Greenpeace's campaign against Golden Rice specifically, and crops and foods improved through biotechnology in general; and to do everything in their power to oppose Greenpeace's actions and accelerate the access of farmers to all the tools of modern biology, especially seeds improved through biotechnology,” the signed letter states.

“Opposition based on emotion and dogma contradicted by data must be stopped. How many poor people in the world must die before we consider this a ‘crime against humanity’?”

The Nobel laureates argue that genetically modified Golden Rice has the ability to decrease Vitamin A deficiencies that trigger blindness and even death in young children living in the poorest parts of the world.

“Greenpeace has spearheaded opposition to Golden Rice, which has the potential to reduce or eliminate much of the death and disease caused by a Vitamin A deficiency (VAD), which has the greatest impact on the poorest people in Africa and Southeast Asia,” the letter said.

According to World Health Organization (WHO) statistics cited in the letter, around 50 million people worldwide suffer Vitamin A deficiency. This includes at least 40 percent of the kids under the age of five.

The men behind the campaign are Richard Roberts, chief scientific officer of New England Biolabs and Phillip Sharp, the winner of the 1993 Nobel Prize in physiology or medicine for the discovery of genetic sequences known as introns.

The surge in genetically engineered (GE) crops since the 1990s has led to a fierce debate over their effect on human health, environmental matters, food security and corporate power.

A new report by the National Research Council, which is criticized for its ties to industry, stated that consumption of genetically modified food has not harmed human health. “The committee concluded that no differences have been found that implicate a higher risk to human health safety from these GE foods than from their non-GE counterparts,” it said.

However, the findings were criticized by Food & Water Watch’s report, “Under the Influence: The National Research Council and GMOs,” which said the NRC accepted millions of dollars in funding from biotech companies.

Statistics reveal that US has been consuming genetically engineered (GE) crops for two decades, with over 90 percent of feed corn, soybeans, and cotton produced in the US labeled as GE.

Supporters of GE crops believe that GMOs have not had a negative impact on human health in that time.

However, opponents of GE foods argue that there are long-term indirect effects that need to be considered.

For example, corporations like Monsanto and Dow Chemical sell their own patented seeds that, given their genetic modification, can be mixed with biocides to kill pests and weeds. This practice can easily jeopardize long-term health of the soil and the biodiversity of a local environment that allows for natural pollination.

The Union of Concerned Scientists believe that “while the risks of genetic engineering are often exaggerated or misrepresented, GE crops do have the potential to cause a variety of health problems and environmental impacts.”

6 Zika-related pregnancies in US, half carried to term with birth defects

In addition to the three babies born with Zika-related defects in the US, three other pregnancies with evidence of the virus were lost, according to the first Centers for Disease Control and Prevention report on Zika pregnancies since their registry launched.

The CDC reported six babies in the US had Zika-related birth defects on Thursday. Three of the babies with evidence of the Zika virus infection survived, but the three others were lost pregnancies.

It was the agency’s first report since launching the Zika pregnancy registry on June 9.

“Although these outcomes occurred in pregnancies with laboratory evidence of Zika virus infection, we do not know whether they were caused by Zika virus infection or other factors,” said the CDC in a released statement.

Zika has caused alarm throughout the Americas since numerous cases of the birth defect microcephaly, linked to the mosquito-borne virus, was reported in Brazil, the country hardest hit by the current outbreak. The rare birth defect is marked by unusually small head size and potentially severe developmental problems. More than 1,400 cases of microcephaly in babies have been confirmed in Brazil.

The CDC declined to provide further details on the six babies. Nor did they say whether the three lost pregnancies were the result of termination, stillbirth or miscarriage. In early June, two US cases of babies with microcephaly were born in Hawaii and New Jersey.

Those two US cases involved women who contracted the virus either outside the US in areas with active Zika outbreaks or through unprotected sex with an infected partner. There have not yet been any cases reported of local transmission of the virus in the US.

"The pattern that we're seeing here in the US among travelers is very similar to what we're seeing in other places like Colombia and Brazil," Dr. Denise Jamieson, co-leader of the CDC Zika pregnancy task force, said in a telephone interview with Reuters.

The CDC said it will begin issuing regular reports on Thursdays of poor outcomes of pregnancies with laboratory evidence of possible Zika virus infection in the 50 states and the District of Columbia. The agency hopes the registry will contribute understanding about the effects of the virus and ensure the most up-to-date information about pregnancy outcomes with Zika virus are publicly available.

“The poor birth outcomes reported include those that have been detected in infants infected with Zika before or during birth, including microcephaly (unusually small head size and severe developmental problems), excess fluid in the brain cavities and surrounding the brain, absent or poorly formed brain structures… or other problems resulting from damage to the brain that affects nerves, muscles and bones such a clubfoot or inflexible joints,” said the CDC in a statement.
