Higher potato consumption associated with increased risk of high blood pressure





Mashed potatoes. Four or more servings a week of baked, boiled, or mashed potatoes was associated with an increased risk of hypertension compared with less than one serving a month in women, but not in men.
Higher intakes of boiled, baked, or mashed potatoes, and French fries is associated with an increased risk of developing high blood pressure (hypertension) in adult women and men, according to a study published by The BMJ today.

The US-based researchers suggest that replacing one serving a day of boiled, baked, or mashed potatoes with one serving of a non-starchy vegetable is associated with a lower risk of developing hypertension.

But a linked editorial argues that studying overall dietary patterns and risk of disease is more useful than a focus on individual foods or nutrients.

Potatoes are one of the world's most commonly consumed foods -- and have recently been included as vegetables in US government healthy meals programs, due to their high potassium content. But the association of potato intake with hypertension has not been studied.


So researchers based at Brigham and Women's Hospital and Harvard Medical School set out to determine whether higher long term intake of baked, boiled, or mashed potatoes, French fries, and potato chips (crisps) was associated with incident hypertension.

They followed over 187,000 men and women from three large US studies for more than 20 years. Dietary intake, including frequency of potato consumption, was assessed using a questionnaire. Hypertension was reported by participants based on diagnosis by a health professional.

After taking account of several other risk factors for hypertension, the researchers found that four or more servings a week of baked, boiled, or mashed potatoes was associated with an increased risk of hypertension compared with less than one serving a month in women, but not in men.

Higher consumption of French fries was also associated with an increased risk of hypertension in both women and men. However, consumption of potato chips (crisps) was associated with no increased risk.

After further analyses, the researchers suggest that replacing one serving a day of boiled, baked, or mashed potatoes with one serving of a non-starchy vegetable is associated with a decreased risk of hypertension.


The authors point out that potatoes have a high glycaemic index compared with other vegetables, so can trigger a sharp rise in blood sugar levels, and this could be one explanation for the findings.

They also acknowledge some study limitations and say that, as with any observational study, no firm conclusions can be drawn about cause and effect.

Nevertheless, they say their findings "have potentially important public health ramifications, as they do not support a potential benefit from the inclusion of potatoes as vegetables in government food programs but instead support a harmful effect that is consistent with adverse effects of high carbohydrate intakes seen in controlled feeding studies."

In a linked editorial, researchers at the University of New South Wales argue that, although diet has an important part to play in prevention and early management of hypertension, dietary behaviour and patterns of consumption are complex and difficult to measure.

"We will continue to rely on prospective cohort studies, but those that examine associations between various dietary patterns and risk of disease provide more useful insights for both policy makers and practitioners than does a focus on individual foods or nutrients," they conclude.

How A Scientist Sounded The Alarm On Sugar Back In The 1950s—But Was Ignored


By Rachel Lapidos for Well+Good


Imagine if people thought you were crazy for saying sugar is bad for you.
British scientist John Yudkin knew the feeling: He died a pariah in the 1970s because he held the unpopular idea that sugar was the number-one health threat, The Guardian reports. Yudkin’s findings from more than a decade of research—published in 1972’s Pure, White, and Deadly: How Sugar is Killing Us and What We Can Do to Stop It—had unfortunate timing, according to the Guardian. At the time, the idea that saturated fat was the number-one health threat was so widespread that Yudkin’s findings were ridiculed and his reputation was ruined.
Today, however, he’s being celebrated by a new breed of “sugar is the devil“ nutritional experts. His ahead-of-his-time claims (last year the US issued guidelines on curbing sugar for the first time) are being championed by people like journalist Nina Teicholz, author of The Big Fat Surprise, and science writer Gary Taubes, who wrote Why We Get Fat, according to the Guardian.

How did Yudkin get overlooked to begin with? He began floating a theory that sugar was a public health hazard in the late 1950s, around the same time that President Dwight Eisenhower suffered a heart attack in office. His doctor treated him with a low-cholesterol regimen (which US health authorities have since backed off from)—an approach that Yudkin was very publicly critical of, the Guardian reports. A bit of a scientific pissing match resulted, and Yudkin lost.

“They took him down so severely—so severely—that nobody wanted to attempt it on their own,” Robert Lustig, a pediatric endocrinologist at the University of California who specializes in the treatment of childhood obesity, told the Guardian.
But posthumously, Yudkin’s findings are back in the scientific mainstream—guiding a new generation of scientists (not to mention documentarians and dessert lovers!). Sweet irony. But a bitter pill for those of us who were careful about cholesterol and saturated fat—ignoring sugar grams—for years.

Meat consumption raises mortality rates, analysis of more than 1. 5 million people finds

A review of large-scale studies involving more than 1.5 million people found all-cause mortality is higher for those who eat meat, particularly red or processed meat, on a daily basis. Conducted by physicians from Mayo Clinic in Arizona, "Is Meat Killing Us?" was published today in the Journal of the American Osteopathic Association.


The authors analyzed six studies that evaluated the effects of meat and vegetarian diets on mortality with a goal of giving primary care physicians evidence-based guidance about whether they should discourage patients from eating meat. Their recommendation: physicians should advise patients to limit animal products when possible and consume more plants than meat.

"This data reinforces what we have known for so long -- your diet has great potential to harm or heal," said Brookshield Laurent, DO, assistant professor of family medicine and clinical sciences at New York Institute of Technology College of Osteopathic Medicine. "This clinical-based evidence can assist physicians in counseling patients about the important role diet plays, leading to improved preventive care, a key consideration in the osteopathic philosophy of medicine."


While findings for U.S. and European populations differed somewhat, the data found the steepest rise in mortality at the smallest increases of intake of total red meat. That 2014 study followed more than one million people over 5.5 to 28 years and considered the association of processed meat (such as bacon, sausage, salami, hot dogs and ham), as well as unprocessed red meat (including uncured, unsalted beef, pork, lamb or game).


A 2014 meta-analysis examined associations with mortality from cardiovascular disease and ischemic heart disease. In that study of more than 1.5 million people, researchers found only processed meat significantly increase the risk for all-cause mortality.

Combined, the findings of these studies are statistically significant in their similarity, the reviewers noted. Further, a 2003 review of more than 500,000 participants found a decreased risk of 25 percent to nearly 50 percent of all-cause mortality for very low meat intake compared with higher meat intake.

They also found a 3.6-year increase in life expectancy for those on a vegetarian diet for more than 17 years, as compared to short-term vegetarians.

Italian court rules food theft 'not a crime' if hungry




The court found that the homeless man was acting "in a state of need" so his actions could not be considered offences
Stealing small amounts of food to stave off hunger is not a crime, Italy's highest court of appeal has ruled.
Judges overturned a theft conviction against Roman Ostriakov after he stole cheese and sausages worth $4.50 from a supermarket.
Mr Ostriakov, a homeless man of Ukrainian background, had taken the food "in the face of the immediate and essential need for nourishment", the court of cassation decided.
Therefore it was not a crime, it said.
A fellow customer informed the store's security in 2011, when Mr Ostriakov attempted to leave a Genoa supermarket with two pieces of cheese and a packet of sausages in his pocket but paid only for breadsticks.
In 2015, Mr Ostriakov was convicted of theft and sentenced to six months in jail and a $100 fine.
'Right and pertinent' ruling, say papers
For the judges, the "right to survival prevails over property", said an op-ed in La Stampa newspaper (in Italian).
In times of economic hardship, the court of cassation's judgement "reminds everyone that in a civilised country not even the worst of men should starve".
An opinion piece in Corriere Della Sera says statistics suggest 615 people are added to the ranks of the poor in Italy every day - it was "unthinkable that the law should not take note of reality".


It criticised the fact that a case concerning the taking of goods worth under $5 went through three rounds in the courts before being thrown out.
The "historic" ruling is "right and pertinent", said Italiaglobale.it - and derives from a concept that "informed the Western world for centuries - it is called humanity".
However, his case was sent to appeal on the grounds that the conviction should be reduced to attempted theft and the sentence cut, as Mr Ostriakov had not left the shop premises when he was caught.
Italy's Supreme Court of Cassation, which reviews only the application of the law and not the facts of the case, on Monday made a final and definitive ruling overturning the conviction entirely.
Stealing small quantities of food to satisfy a vital need for food did not constitute a crime, the court wrote.

"The condition of the defendant and the circumstances in which the seizure of merchandise took place prove that he took possession of that small amount of food in the face of an immediate and essential need for nourishment, acting therefore in a state of necessity," wrote the court.

We Owe Our Caffeine Addiction To Goats That Got High



As you sip your cup of morning joe or cappuccino, don't forget to thank goats. Why? Because, legend has it, it's thanks to them that we even have coffee. As the story goes, an Ethiopian goatherd named Kaldi was minding his own business one day when he found his charges getting super-frisky. They were nibbling on the berries and leaves of a mysterious plant, leading them to dance on their hind legs. Kaldi decided to take a bite of the berries and experienced a rush of energy. He took the berries to a holy man who tossed them on a fire, emitting the heavenly scent of coffee we know and love today. Someone wise took the roasted beans from the embers of the fire and used them to brew a cup of what we guzzle today! The word "coffee" itself may derive from the Ethiopian region of Kaffa, though Yemenites claim their country as the place of origin. Look at this gorgeous cup of cappuccino! Thanks, goats. 



Whether or not goats actually led humans to discover coffee, Ethiopia was one place with a strong coffee history. The first written reference to coffee came in the tenth century, courtesy of the great Persian doctor named Rhazes, author of one thousand books, though the drink was probably made for centuries beforehand. Rhazes referred to bunn, as it was referred to in Ethiopia, of which he quipped, “It is a drink that is good for those with hot nature, but it decrease[s] the libido." Unfortunately, this probably wasn't the exact same kind of brew that we drink today, which didn't appear for another few centuries.
