Alcohol-Related Brain Damage

download

It’s hardly a secret that alcohol affects the brain — its initial effects include wobbly walking, blurred vision, and slurred speech. But although drinking in moderation isn’t necessarily harmful, and can even help with creativity, researchers in the UK are warning that the long-term effects of drinking may go further than the liver, affecting the brain in more permanent ways.

The report, “All in the Mind,” from Alcohol Concern Cymru, a charity based in London, is a supposed “wake up call” for both the public and health care providers. It highlights the dangers of alcohol-related brain damage (ARBD), an umbrella term for a range of conditions resulting from long-term drinking. These include confusion, poor concentration, memory loss, and depression, as well as other issues that may arise from drinking, like traumatic brain injuries (from falling while drunk) and ophthalmoplegia — a weakness or paralysis of the eye.

Many of these problems are also characteristics of a disease known as Wernicke-Korsakoff syndrome (WKS), a debilitating and long-lasting syndrome that actually consists of two separate conditions, according to the National Institutes of Health. One of them, known as Wernicke’s encephalopathy, is defined by mental confusion, eye paralysis, and problems with muscle coordination — oftentimes not altogether. Korsakoff’s psychosis is the other condition, characterized by persistent learning and memory problems.

“Most of us know that alcohol can damage our liver, but the fact that it could undermine our long-term brain function is much less well-known,” said Andrew Misell, director of Alcohol Concern Cymru, in a statement. “And when alcohol-related brain damage is on the radar, the focus is often on older street drinkers. But staff on the frontline have been seeing younger people, and other people who don’t fit the stereotype of a homeless dependent drinker, coming in with ARBD. … We hope this paper will be a wake-up call for all of us who drink.”

Alcohol Concern says that while moderation is key, many people instead go through periods during which they drink heavily, then abstain. The charity notes that vitamin deficiency is a major contributor to ARBD — 80 percent of alcoholics are vitamin deficient — and suggests increasing intake of vitamin B1, also called thiamine, which can be given through injections or pills

Mom of Newborn Twins Fights Rare Placenta Cancer

download

Jenna Hinman is fighting for her life in a medically-induced coma after she gave birth to healthy twins at 30 weeks pregnancy, only to discover she had a rare cancer of the placenta that has filled her lungs with tumors.

The 26-year-old mother is in “critical but stable” condition at Crouse Hospital in Syracuse, N.Y. The twin baby girls, Kinleigh and Azlynn are doing fine at 2 pounds, 9 ounces, and 3 pounds, 6 ounces, respectively.

“We’re hanging in there,” her husband, U.S. Army Sgt. Brandon Hinman, told ABCNews.com. “We are just taking it day to day, but we are starting to get some positive results and are pretty happy about that. The chemo is starting to have an effect.”

“The twins are doing well and don’t have breathing tubes anymore,” said Hinman, 30, who is stationed at Fort Drum. “Both are feeding and right where they need to be at 30 weeks.”
Crouse Hospital spokesman Bob Allen said her treatment was “a highly rare situation here, not just because of the pregnancy-related cancer, which is a big piece of it, but the fact that she is on ECMO technology.”

ECMO or extracorporeal membrane oxygenation is a therapy that uses a pump to circulate blood through an artificial lung back into the bloodstream. The most common conditions that may require ECMO are: heart malformations, severe air leak problems and severe pulmonary hypertension, according to the National Institutes of Health.

Jenna Hinman, a recreational therapist, began to go into labor on March 3 and was rushed to the emergency room at Good Samaritan Hospital in Watertown, N.Y., where the twins were delivered by emergency C-section. The same day, the twins were transported to Crouse Hospital in Syracuse where its Walter R.G. Baker Neonatal Intensive Care Unit is the only one in the in central New York designated as a regional perinatal center.

The new mother had only a quick visit with the babies before they were taken to the Crouse NICU. When Jenna Hinman began coughing up blood, she, too was transferred to Crouse.

“She was really in distress with breathing difficulties,” Crouse Hospital spokesman Cheryl Abrams told ABCNews.com. “It was a situation where the babies were in distress, too.”

At first doctors suspected pneumonia, but three days later, they diagnosed stage 3 choriocarcinoma.

Choriocarcinoma is a malignant form of gestational trophoblastic disease (GTD), tumors that involve abnormal growth of cells inside a woman’s uterus. This particular type affects only about 2 to 7 of every 100,000 pregnancies in the United States, according to the American Cancer Society.

Choriocarcinoma is much more likely than other types of GTD to grow quickly and spread to organs away from the uterus. About one-quarter of women who develop this disease miscarry.

Chief of Medicine for Crouse Hospital Dr. David Landsberg said stage 3 cancer had invaded Hinman’s lungs but had not gone to the brain. The cancer itself is “curable tumor,” he said.

“Placental tissue grows at a very rapid rate to support the fetus, which explains why the cancer is so aggressively metastatic,” he said. “It grows into the uterus and once it gets out, it’s looking for somewhere else to grow.”

Without ECMO, her condition would be “100 percent fatal,” said Landsberg. “The chemo will be the real cure. The ECMO is keeping her alive for the chemo to do its job.”

He said a cure was “on the edge of what is possible.”

Organ donation after cardiac death

organ

At only 32, Sarah Beth Therien suddenly became unconscious. She was rushed to hospital — and would never wake up. An unexpected heart arrhythmia had left her on life support. “A machine kept her heart pumping, but we knew she was gone,” said Emile Therien, her father.

After a week, Emile Therien and his wife, Beth Therien, made the difficult decision to withdraw life support.
Their daughter had always wanted to donate her organs, but she didn’t meet the brain death criteria required for donation. Her Ottawa family was determined to fulfill her final wish. In 2006, she became the first Canadian in nearly four decades to donate her organs after cardiac death — not brain death. And the decision didn’t go unnoticed.

Six years later in 2012, among the 540 deceased organ donors in Canada nearly 14 per cent donated after cardiac death. Cardiac death donation, also called non-heart-beating donation is now practised in Ontario, British Columbia, Alberta, Quebec, and Nova Scotia.

Canada joins other countries like the United Kingdom, United States, Spain, and the Netherlands, where non-heart-beating donation is more widespread.

Donation guidelines revised

Donation after cardiac death was the only method of deceased organ donation prior to the advent of brain death criteria in the 1960s — when the concept of someone being “brain dead” was first introduced. Because the brain dies before the heart, organs taken after brain death aren’t damaged from a lack of blood flow. As a result, donation after brain death replaced cardiac-death donation.

But over the last two decades, organ shortages, improved organ preservation, and public support led to the re-emergence of donation after cardiac death. In Canada, a national forum of transplant experts in 2005 led to the development of new guidelines that paved the way for this type of donation. And made it possible for Sarah Beth Therien to be a donor.

The potential impact is huge. Brain death accounts for only 1.5 per cent of in-hospital deaths. For the majority of patients with non-survivable illness, death occurs as a result of cardiac death after life support is removed.

Donation after cardiac death could increase the number of available organs by 10 to 30 per cent, according to experts. This could mean the difference between life and death for the nearly 4,500 Canadians currently waiting for a transplant, many of whom will die before getting organs.

The most common organs donated after cardiac death are kidneys, followed by livers, lungs, and pancreases.
Success depends on timing of organ removal

The success rate at which potential donors end up donating organs after cardiac death depends on the organs being removed — kidneys last longer than livers after the heart stops, for instance — how long it takes for the patient to actually die, and the person’s blood pressure and oxygen levels during the dying process, Shemie says.

And organs donated after cardiac death may not always work as well as those donated after brain death.

Higher rates of dysfunction have been seen in livers taken after cardiac death, says Dr. William Wall, director of the multi-organ transplant program at London Health Sciences Centre in Ontario. Kidneys donated after cardiac death have trouble working initially, but “one-year functioning is similar for kidneys taken after cardiac versus brain death,” Wall says.

For Emile and Beth Therien, pioneering the process meant a lot. Sarah Beth Therien donated two kidneys and two corneas, changing the lives of four Canadians. Each donor has the potential to save up to eight lives.

“Sarah was able to save other Canadians. Nothing could have made us happier,” Emile Therien says.

Doctors Use 3-D Printing To Help A Baby Breathe

Ever since the day Garrett Peterson was born, his parents have had to watch him suddenly just stop breathing.

“He could go from being totally fine to turning blue sometimes — not even kidding — in 30 seconds,” says Garrett’s mother, Natalie Peterson, 25, of Layton, Utah. “It was so fast. It was really scary.”

Garrett was born with a defective windpipe. His condition, known as tracheomalacia, left his trachea so weak the littlest thing makes it collapse, cutting off his ability to breathe.

“When he got upset, or even sometimes just with a diaper change, he would turn completely blue,” his mother says, “and that was terrifying.”So the Petersons contacted Dr. Glenn Green at the University of Michigan, who specializes in conditions like Garrett’s. He teamed up with Scott Hollister, a biomedical engineer who runs the university’s 3-D Printing Lab, to create a remarkable solution to Garrett’s problem — a device that will hold open Garrett’s windpipe until it’s strong enough to work on its own.

Instead of shooting ink onto a flat page to print words or pictures, 3-D printers use other material, such as plastic or metal, to create three-dimensional objects. “You build up layers until you have the complete 3-D structure,” Hollister says.

3-D printers have been used to build jewelry, art and even guns. But Hollister is using the technology to create medical devices. He uses a 3-D printer that melts particles of plastic dust with a laser. He has already built a jawbone for a patient in Italy and has helped another baby with a condition similar to Garrett’s. But Garrett is a lot of sicker and his condition is a lot more complicated.

“It’s just been issue after issue with breathing, and just trying to keep him breathing at all,” Jake Peterson, Garrett’s dad, says.

At 16 months old, Garrett had never been able to leave the hospital. Every time he stopped breathing, it was a mad rush to save him. And the doctors weren’t sure how much longer they could keep him alive.

“In some sense we were thrown directly into the fire,” Hollister says. “We characterized it as sort of a Hail Mary pass.” So they rushed Garrett from Salt Lake City to Ann Arbor on Jan. 18 and got to work.

First they took a CT scan of Garrett’s windpipe so they could make a 3-D replica of it. Next they used the 3-D printer to design and build a “splint.” It’s a small, white flexible tube tailored to fit around the weakest parts of Garrett’s windpipe.

“It’s like a protective shell that goes on the outside of the windpipe and it allows the windpipe to be tacked to the inside of that shell to open it up directly,” Green says.

But the device has not been approved by the Food and Drug Administration. So Green and Hollister had to convince the agency to give them an emergency waiver to try it. And they were running out of time. “His condition was critical. It was urgent and things needed to be done quickly. It was highly questionable whether he would survive and how long he would survive,” Green says.

Garrett’s parents knew they were taking a leap of faith. But they felt like they had to try. “We were just so excited for that glimmer of hope that this could be what would help Garrett get home,” Jake Peterson says.

Hollister and Green got the FDA’s approval and scheduled the surgery for Jan. 31. As soon as the surgeon, Dr. Richard Ohye, opened up Garrett’s chest, he and Green could see that Garrett’s windpipe had collapsed. One of his lungs was completely white.

“The only time I’d seen a white lung was in somebody that had died,” Green says. They quickly got to work, gingerly placing the first of two splints on one side of Garrett’s windpipe. It fit perfectly. So they got started on a second splint, which fit perfectly, too.

After more than eight hours, both splints were securely in place. Then came the most important moment: What would happen when they let air flow through Garrett’s windpipe into his lungs?

This time, Garrett’s windpipe stayed open, and his white lung turned pink. “That was just amazing to me,” Green says. “Here something that we’d worked on, that had been constructed just a week ago to match this defect. It had worked just the way we had hoped. I said, ‘This is going to change this boy’s life and his family’s life forever.’ ”

Garrett is 18 months old now and is still in the hospital, but in the weeks since the surgery, he has gotten stronger and stronger and needs less help breathing. His parents are ecstatic.

“He has been doing so good. He’s been smiling, and it’s crazy to be able to see him get really upset and not change colors,” Natalie Peterson says. “He’s being more interactive and more alert and reaching more for his toys. He’s just starting to be more like a normal child,” Jake Peterson adds. Garrett’s splint is designed to expand as he grows and eventually dissolve in his body as his own windpipe gets strong enough to work normally.

Green wants to save more babies this way, but it’s expensive to transport these extremely sick children across country. It has also been hard to convince insurance companies to pay for the trip.

“It is one of the most frustrating things that I’ve been through, knowing that there’s something that we have that can help and looking at all the roadblocks that are in place,” Green says. So he’s hoping to launch a formal study, which may enable him to try more splints to save more babies.

Green says this is the most exciting thing he has seen since medical school. “We’re talking about taking something like dust and converting it into body parts,” he says. “And we’re able to do things that were never possible before.” They’ve already started using 3-D printing to build more body parts, including ears and noses, by combining the plastic structure with human cells. Other scientists have gone even further, using 3-D printing to make blood vessels, skin and even primitive organs out of cells.

Outdoor exercise becoming popular

The gym appears to be giving way to outdoor exercises. Research shows that one in three women are shunning working out at the gym.

In an effort to workout in fresh air, 56 percent of health enthusiasts said they would definitely not be returning to the gym, femalefirst.co.uk reports.

The increasing popularity of functional workouts, boot camps and small group personal training sessions has fuelled the growth in the number of outdoor exercise options.

Being cheaper is also one of the main reasons women have decided to ditch the gym. But they also admitted that they feel more comfortable exercising in a less confined space with people watching.

Study To Test ‘Chocolate Pills’ For Heart Health

It won’t be nearly as much fun as eating candy bars, but a big study is being launched to see if pills containing the nutrients in dark chocolate can help prevent heart attacks and strokes.

The pills are so packed with nutrients that you’d have to eat a gazillion candy bars to get the amount being tested in this study, which will enroll 18,000 men and women nationwide.

“People eat chocolate because they enjoy it,” not because they think it’s good for them, and the idea of the study is to see whether there are health benefits from chocolate’s ingredients minus the sugar and fat, said Dr. JoAnn Manson, preventive medicine chief at Harvard-affiliated Brigham and Women’s Hospital in Boston.

The study will be the first large test of cocoa flavanols, which in previous smaller studies improved blood pressure, cholesterol, the body’s use of insulin, artery health and other heart-related factors.

A second part of the study will test multivitamins to help prevent cancer. Earlier research suggested this benefit but involved just older, unusually healthy men. Researchers want to see if multivitamins lower cancer risk in a broader population.

The study will be sponsored by the National Heart, Lung and Blood Institute and Mars Inc., maker of M&M’s and Snickers bars. The candy company has patented a way to extract flavanols from cocoa in high concentration and put them in capsules. Mars and some other companies sell cocoa extract capsules, but with less active ingredient than those that will be tested in the study; candy contains even less.

“You’re not going to get these protective flavanols in most of the candy on the market. Cocoa flavanols are often destroyed by the processing,” said Manson, who will lead the study with Howard Sesso at Brigham and others at Fred Hutchinson Cancer Research Center in Seattle.

Participants will get dummy pills or two capsules a day of cocoa flavanols for four years, and neither they nor the study leaders will know who is taking what during the study. The flavanol capsules are coated and have no taste, said Manson, who tried them herself.

In the other part of the study, participants will get dummy pills or daily multivitamins containing a broad range of nutrients.

Participants will be recruited from existing studies, which saves money and lets the study proceed much more quickly, Manson said, although some additional people with a strong interest in the research may be allowed to enroll. The women will come from the Women’s Health Initiative study, the long-running research project best known for showing that menopause hormone pills might raise heart risks rather than lower them as had long been thought. Men will be recruited from other large studies.

Manson also is leading a government-funded study testing vitamin D pills in 26,000 men and women. Results are expected in three years.

People love vitamin supplements but “it’s important not to jump on the bandwagon” and take pills before they are rigorously tested, she warned.

“More is not necessarily better,” and research has shown surprising harm from some nutrients that once looked promising, she said.

How to Unleash the Power of Garlic

This seasoning does more than kick up marinara. It stops sniffles, wards off UTIs, and may even help prevent cancer. Who knew garlic could have so many benefits?

Clear up UTIs
Cranberry juice isn’t the only natural way to fight annoying urinary tract infections. A diet rich in garlic can help, too, thanks to the bulb’s natural antimicrobial properties, says Amanda Ursell, author of The Complete Guide to Healing Foods. Garlic bread, anyone?

Crush cancer
The next time you’re cooking, mince the garlic ahead of time. Nutritionists at the American Institute for Cancer Research found that letting chopped or crushed garlic sit for 10 minutes before heating helps it retain a third more of its cancer-fighting sulfur compounds than if it were cooked immediately.

Fight itchy feet
Got athlete’s foot? Reach for garlic, a powerful antifungal, says Debra Rouse, a naturopathic physician in Denver. Just boil several cloves in hot water, cool to a comfortable temperature, pour into a large bowl, and soak your feet. (Boiled and uncrushed garlic won’t leave a smell.)

Combat a cold
At the first sign of the sniffles, try this get-well trick from Gowsala Sivam, PhD, of Bastyr University in Kenmore, Washington. Microwave 2 cloves unpeeled garlic for 25 seconds; let it cool, then peel off the skin and eat. Garlic’s sulfur compounds likely boost the immune system and help fight infection, Sivam says.

Let it bloom:
Plant garlic next to your rose bushes to naturally repel pests.

Unease grows among U.S. doctors over Indian drug quality

Some U.S. doctors are becoming concerned about the quality of generic drugs supplied by Indian manufacturers following a flurry of recalls and import bans by the Food and Drug Administration.

India supplies about 40 percent of generic and over-the-counter drugs used in the United States, making it the second-biggest supplier after Canada.

In recent months, the FDA, citing quality control problems ranging from data manipulation to sanitation, has banned the importation of products from Ranbaxy Laboratories Ltd, Wockhardt Ltd and, most recently, Sun Pharmaceutical Industries Ltd.

“I’m just beginning to realize the gravity of the problem,” said Dr. Steven Nissen, head of cardiology at the Cleveland Clinic. “It’s terrible and it is starting to get a lot of traction among physicians.”

Indian drugmakers are by no means the only companies to recall products or be warned by the FDA about manufacturing problems. For instance, quality control failures at Johnson & Johnson forced the company to recall dozens of products over the past five years, ranging from artificial hips to children’s Tylenol.

And last year, Germany’s Boehringer Ingelheim said it would shut down its U.S. contract manufacturing unit, Ben Venue Laboratories, after it was cited for repeated manufacturing violations that led to shortages of the cancer drug Doxil.

India’s drugmakers, a $14 billion industry, reject any criticism that their products are inferior to drugs made in other countries.

“We have heard doctors making generalized statements, without being specific on any product or company,” said D.G. Shah, Secretary General of the Indian Pharmaceutical Alliance, a trade group representing large Indian drugmakers. “This is a deliberate and serious campaign to malign the Indian generic industry.”

If U.S. doctors come across a medicine that does not meet quality standards, they should report it to regulators, he said. “Doctors are not in a position to judge whether manufacturing processes are correct or not. That is the U.S. FDA’s job.”

Generic drugs account for nearly 85 percent of medicines prescribed in the United States and the government is relying on them to help rein in healthcare costs.

“We are losing control over what people are swallowing,” said Dr. Harry Lever, a cardiologist at the Cleveland Clinic who is trying raise awareness of the matter among U.S. lawmakers. “Now, when a patient comes in who is not doing well, the first thing I do is look at their drugs and find out who makes it.”

Increasingly, Lever said, he is recommending patients seek out generic drugs from specific manufacturers outside India.

“I’m tending to stay away from India,” he said. “There’s something wrong. Too many things are happening.”

INDIA DOCTORS HIT BACK

Indian physicians do not share the concerns.

“Our drugs are being sold in many countries and being accepted, so we have no issues,” said Narendra Saini, Secretary General of the Indian Medical Association, a voluntary body of 215,000 doctors. “How do I know that Western drugs are better than our drugs?”

A 2012 report by India’s parliament alleged collusion between pharmaceutical firms and officials at the Central Drugs Standard Control Organization (CDSCO), the country’s drugs regulator, and described an agency that was both understaffed and underqualified.

Saini said physicians trust that the CDSCO is taking care of the quality and the standard of the drugs made in India.

“We very much trust those medicines,” he added.

Representatives of Ranbaxy, Sun and Wockhardt were not immediately available to comment.

Dr. Joel Zonszein, director of the Clinical Diabetes Center at Montefiore Medical Center in New York, said he is concerned about the quality of generic drugs in general, not just those from India. He cited, as an example, his experience with the diabetes drug metformin.

“When patients open the bottle of medication it smells like dead fish,” he said. Zonszein did not know which company made the foul-smelling drug.

Physicians do not have a say in which generic drug a patient receives, as that depends on which products are stocked by individual pharmacies. If a patient wants to avoid a certain manufacturer, he or she may have to change pharmacies.

Doctors may specify that the branded version of a drug be dispensed, but insurance companies frequently refuse to pay for them.

Dr. Richard Kovacs, who heads a number of American College of Cardiology committees and sits on its board of trustees, said doctors may need to play a greater role monitoring the medications prescribed by their practices.

“The average U.S. cardiologist has been able to assume that the drugs were safe and effective. It now appears we need to be more vigilant as a profession, and assist the FDA by reporting cases where we are concerned about irregularities in the drugs supplied to our patients,” he said.

Saturated fat advice ‘unclear’

_73638186_fried_sausages-spl-1

Swapping butter for a sunflower spread may not lower heart risk, say British Heart Foundation researchers.

Contrary to guidance, there is no evidence that changing the type of fat you eat from “bad” saturated to “healthier” polyunsaturated cuts heart risk.

They looked at data from 72 studies with more than 600,000 participants.

Heart experts stressed the findings did not mean it was fine to eat lots of cheese, pies and cakes.

Too much saturated fat can increase the amount of cholesterol in the blood, which can increase the risk of developing coronary heart disease.

Saturated fat is the kind of fat found in butter, biscuits, fatty cuts of meat, sausages and bacon, and cheese and cream.

Most of us eat too much of it – men should eat no more than 30g a day and women no more than 20g a day.

There has been a big health drive to get more people eating unsaturated fats such as olive and sunflower oils and other non-animal fats – instead.

But research published in Annals of Internal Medicine, led by investigators at the University of Cambridge, found no evidence to support this.

Total saturated fat, whether measured in the diet or in the bloodstream as a biomarker, was not associated with coronary disease risk in the 72 observational studies.

And polyunsaturated fat intake did not offer any heart protection.

Dr Rajiv Chowdhury, the lead author of the research , said: “These are interesting results that potentially stimulate new lines of scientific inquiry and encourage careful reappraisal of our current nutritional guidelines.”

The British Heart Foundation said the findings did not change the advice that eating too much fat is harmful for the heart.

Prof Jeremy Pearson, the charity’s associate medical director, said: “This research is not saying that you can eat as much fat as you like.

“Too much fat is bad for you.

“But, sadly, this analysis suggests there isn’t enough evidence to say that a diet rich in polyunsaturated fats but low in saturated fats reduces the risk of cardiovascular disease.

“Alongside taking any necessary medication, the best way to stay heart healthy is to stop smoking, stay active, and ensure our whole diet is healthy – and this means considering not only the fats in our diet but also our intake of salt, sugar and fruit and vegetables.”

Middle-aged? Put down the meat

Eating a high-protein diet in middle age could increase your risk of diabetes and cancer, according to a study published this week in the journal Cell Metabolism. But don’t stay away from meat for too long – the same study showed those over 65 need more protein to reduce their mortality risk.

Insulin-like growth factor 1, or IGF-1, is a protein in your body related to growth and development. Past studies have linked IGF-1 to age-related diseases, including cancer. Mice and humans with higher levels of IGF-1 often have a higher risk of developing these diseases.

Scientists believe protein intake plays a role in IGF-1 activity. Eating less protein, studies have shown, can lead to lower levels of IGF-1 in your body. So theoretically, protein consumption could be directly linked to disease incidence and death.

The study

Researchers analyzed survey data from 6,381 U.S. men and women aged 50 and above to understand the link between protein, certain diseases and mortality.

The study participants were split into three groups: a high-protein group who ate 20% or more of their daily calories from proteins; a moderate-protein group who ate 10 to 19% of their calories from proteins; and a low-protein group.

Researchers also looked at the differences in risk between those aged 50 to 65 and those over 65 years old.

The results

People between the ages of 50 and 65 who ate a high-protein diet had a 74% increase in overall mortality compared to those in the low-protein group. The meat lovers also had four-fold increased risk of dying from cancer during the study’s 18-year follow-up.

However, this risk was only seen in those who got their protein from animal sources such as meat, eggs and cheese; the link disappeared if the protein came from plants, such as nuts, seeds and beans.

People who were over the age of 65 and ate a high-protein diet saw the opposite effect. Researchers saw a 28% reduction in death from all causes in this group. Cancer deaths in this older, high-protein group, were also reduced.

Study participants of any age who ate a high-protein diet had a five-fold increased risk of dying from diabetes.

The scientists had IGF-1 data for more than 2,200 people in the study. Analyzing this information, they determined that for every IGF-1 increase of 10 ng/ml, those on a high-protein diet were 9% more likely to die from cancer than those on a low-protein diet.

The study authors concluded that high levels of animal proteins cause increased levels of IGF-1 and possibly insulin in the body, which leads to higher mortality for people ages 50 to 65.

Tumors in mice

Researchers also reported on a separate experiment, where lab mice were either on a high-protein or a low-protein diet. Mice on the low-protein diet had a lower cancer rate than those on a high-protein diet, even after being implanted with 20,000 melanoma cells. The low-protein mice also had smaller tumors on average than those on a high-protein diet by the end of the six-week experiment.

When the mice were switched from a high-protein diet to a low-protein diet, researchers saw a 30% decrease in their IGF-1 levels.

“Almost everyone is going to have a cancer cell or pre-cancer cell in them at some point. The question is: Does it progress?” study author Valter Longo said in a press release. “Turns out one of the major factors in determining if it does is protein intake.”

Takeaway

Eating more than 10% of your calories from animal proteins in middle age could increase your risk of dying from diseases such as cancer and diabetes. But after 65, you may need that extra protein to protect your body from becoming frail.

“The majority of Americans are eating about twice as much proteins as they should,” Longo said. “It seems that the best change would be to lower the daily intake of all proteins, but especially animal-derived proteins.”

Walter Willett, an epidemiologist at Harvard’s School of Public Health, says not much should be made of this study’s findings. It’s unreasonable to treat “animal protein” as one class, he says, as fish, poultry and red meat are all very different.

Willett also noted that the headline on the press release associated with this study – “Meat and cheese may be as bad for you as smoking” – is a vast overstatement. The researchers did not include data on smoking in their study.

The Institute of Medicine’s Food and Nutrition Board recommends eating about 0.8 grams of protein per kilogram of body weight every day in middle age. So a 160-pound person should eat about 55 to 60 grams of protein a day.
