BLACK  FRIDAY


Samtidigt som readagen Black Friday väntas slå nya försäljningsrekord i år så växer en motrörelse fram. Naturskyddsföreningen har startat ett Facebook-evenemang där över 25 000 personer klickat i att de tänker bojkotta shoppingdagen för att inte bidra till överdriven konsumtion, skriver Breakit. ”Tänker på tillverkningen, miljögifter, frakten hit. Det är ett vansinne utan slut och vi är alla medlöpare”, skriver en av deltagarna i evenemanget.

Det är inte alla som älskar de importerade shoppingdagarna.

Lövblåsare lever loppan

Det är höst här och massor av mexikanska trädgårdsarbetare kommer körandes i sina gamla trasiga lastbilar. Ut tumlar ett gäng brunbrända mexikaner med gigantiska lövblåsare. De trycker på knappen och hela gatan börjar skaka.
När jag var liten så läste vi Tant Brun, Tant Grön och Tant Gredelin, och när tanterna inte stod och bakade kakor så krattade dom löv. I alla fall Tant Grön – har jag för mig.
Men idag vill ingen trärdgårdsarbetare med självaktning bli sedd med en gammaldags kratta. Alla vill vara högteknologiska och det är därför som man aldrig kan sova på lördagsmorgonen. Kl. slår en-två-tre-fyra-fem-sex BOOOOOOOOM hela huset skakar och vi ser vad som ser ut som soldater direkt från Irak med solglasögon, skyddskläder och något som mest liknar en gigantisk Bazooka.
Det tar timmar att blåsa våra få löv in på grannens tomt. Det hade tagit femton minuter med en kratta. Sedan kommer grannens lövblåsare några timmar senare och blåser löven tillbaks på min tomt.
Palo Alto har förbjudet de flesta lövblåsare men för oss som inte bor i gräddfilen så finns det inga alternativ, det är bara att köpa öronproppar och vänta på våren.Källa USA-bloggen

The Key to Weight Loss Is Diet Quality, Not Quantity, a New Study Finds


How a Low-Carb Diet Might Help You Maintain a Healthy Weight

Adults who cut carbohydrates from their diets and replaced them with fat sharply increased their metabolisms.Adults who cut carbohydrates from their diets and replaced them with fat sharply increased their metabolisms.

It has been a fundamental tenet of nutrition: When it comes to weight loss, all calories are created equal. Regardless of what you eat, the key is to track your calories and burn more than you consume.

But a large new study published on Wednesday in the journal BMJ challenges the conventional wisdom. It found that overweight adults who cut carbohydrates from their diets and replaced them with fat sharply increased their metabolisms. After five months on the diet, their bodies burned roughly 250 calories more per day than people who ate a high-carb, low-fat diet, suggesting that restricting carb intake could help people maintain their weight loss more easily.

The new research is unlikely to end the decades-long debate over the best diet for weight loss. But it provides strong new evidence that all calories are not metabolically alike to the body. And it suggests that the popular advice on weight loss promoted by health authorities — count calories, reduce portion sizes and lower your fat intake — might be outdated.

“This study confirms that, remarkably, diets higher in starch and sugar change the body’s burn rate after weight loss, lowering metabolism,” said Dr. Dariush Mozaffarian, the dean of the Friedman School of Nutrition Science and Policy at Tufts University, who was not involved in the research. “The observed metabolic difference was large, more than enough to explain the yo-yo effect so often experienced by people trying to lose weight.”


WELL

Here's why people who work out tend to be more cheerful than those who never exercise.


Dr. Mozaffarian called the findings “profound” and said they contradicted the conventional wisdom on calorie counting. “It’s time to shift guidelines, government policy and industry priorities away from calories and low-fat and toward better diet quality.”
The new study is unique in part because of its size and rigor. It is among the largest and most expensive feeding trials ever conducted on the subject. The researchers recruited 164 adults and fed them all of their daily meals and snacks for 20 weeks, while closely tracking their body weight and a number of biological measures. The trial cost $12 million and was supported largely by a grant from the Nutrition Science Initiative, a nonprofit research group co-founded by Gary Taubes, a science and health journalist and proponent of low-carbohydrate diets. The study was also supported by funding from the New Balance Foundation, the National Institutes of Health and others.
While some experts praised the findings, others were more cautious. Dr. Kevin Hall, a scientist and obesity expert at the National Institute of Diabetes and Digestive and Kidney Diseases, said the new study was ambitious and very well run. But he said the researchers used methods that raise questions about the results. One method they used to track metabolism, called doubly labeled water, has not been shown to be reliable in people on low-carb diets and it may have exaggerated the amount of calories the subjects burned, he said.


Dr. David Ludwig, an endocrinologist at Harvard Medical School and Boston Children’s Hospital and one of the study authors, disagreed, saying: “We used a gold standard method that has been validated across a wide range of experimental conditions and universally adopted in the field.

Dr. Hall added, “I would love it to be true that there was a diet combination of carbs and fats that led to large increases in energy expenditure — and I really hope it is true. But I think there are reasons to question whether or not it is.”


WELL

Here's how a low-carb diet might aid people with Type 1 diabetes.


The idea that counting calories is the key to weight loss has long been embedded in the government’s dietary guidelines. It is the driving force behind public health policies like mandatory calorie counts on restaurant menus and food labels. Many experts say that the underlying cause of the obesity epidemic is that Americans eat too many calories of all kinds, prompted by easy access to cheap and highly palatable foods, and that they need to exercise portion control. On its website, for example, the National Institutes of Health encourages people to count calories and warns that dietary fat has more calories per gram than protein or carbs: “You need to limit fats to avoid extra calories,” it states.
But experts like Dr. Ludwig, argue that the obesity epidemic is driven by refined carbohydrates such as sugar, juices, bagels, white bread, pasta and heavily processed cereals. These foods tend to spike blood sugar and insulin, a hormone that promotes fat storage, and they can increase appetite. Dr. Ludwig and his colleague Dr. Cara Ebbeling have published studies suggesting that diets with different ratios of carbs and fat but identical amounts of calories have very different effects on hormones, hunger and metabolism. He has also written a best-selling book on lower-carb diets.
Dr. Hall and others disagree. They have published studies disputing the notion that carb-restricted diets accelerate metabolism and fat loss. Dr. Hall said that low-carb diets have many benefits: They can help people with Type 2 diabetes manage their blood sugar levels, for example. But he argues that the carb and insulin explanation for obesity is too simplistic and has been “experimentally falsified” in rigorous studies.
Dr. Hall published a meta-analysis of feeding studies last year that suggested that energy expenditure was actually slightly greater on low-fat diets. But Dr. Ludwig pointed out that those studies were very short, with none lasting longer than a month and most lasting a week or less. He said the process of adapting to a low-carb diet can take a month or longer.


“A few days, or a couple weeks, is not enough time to make any meaningful conclusion about how diets affect metabolism over the long term,” he added.


To do the new study, Dr. Ludwig and his colleagues collaborated with Framingham State University, about 20 miles outside of Boston, where they recruited overweight students, staff members and faculty members. Each participant went through two phases of the study. First, they were put on strict diets that lowered their body weight by about 12 percent, which was designed to stress their metabolisms.
“At that point their bodies are trying to regain the weight,” Dr. Ludwig said. “It pushes the body and predisposes to weight regain.”
In the second phase of the study, the subjects were assigned to one of three diets with 20 percent, 40 percent or 60 percent of their calories from carbohydrates. Protein was kept steady at 20 percent of calories in each diet.
Over the next five months, the researchers tracked the subjects meticulously and provided them with enough daily meals and snacks to keep them from losing or gaining any weight. This was so the researchers could determine precisely how the subjects’ metabolisms responded to the different diets while their body weight remained stable.
The researchers tracked biomarkers that helped them ensure that the participants stuck to their diets. They also worked with a large food service company, Sodexo, to prepare thousands of generally healthful meals that the subjects could eat in cafeterias or take home with them. A typical meal for the high-carb group might consist of a chicken burrito bowl with rice and vegetables, for example, or roasted turkey with green beans and mashed potatoes. The low-carb group would get a similar meal with fewer carbohydrates, like a chicken burrito lettuce wrap or roasted turkey with green beans and mashed cauliflower.
What the researchers found was striking. The roughly 250 extra calories that the subjects in the low-carb group burned each day could potentially produce a 20-pound weight loss after three years on the diet, Dr. Ludwig said. People who tended to secrete higher levels of insulin did the best on the low-carb diet, burning about 400 extra calories a day.
The subjects on the low-carb diet also had the sharpest declines in a hormone called ghrelin, which is produced in the stomach. Ghrelin promotes hunger and body fat, and it lowers energy expenditure. Suppressing ghrelin may be one reason the low-carb diet increased metabolism, the authors noted.

















Dr. Ludwig emphasized that the results need to be replicated by other investigators and he stressed that the findings do not impugn whole fruits, beans and other unprocessed carbohydrates. Rather, he said, the study suggests that reducing foods with added sugar, flour and other refined carbohydrates could help people maintain weight loss by increasing their metabolisms at a lower body weight.
“These foods seem to undermine your metabolism,” he said. “They slow metabolism in a way that may work against long-term weight loss maintenance.”

How to Delete Facebook and Instagram From Your Life Forever

Lost faith in Facebook and Instagram after data leakages, breaches and too much noise? Here’s a guide to breaking up with the social network and its photo-sharing app for good.

You may have decided enough is enough: It’s time to delete Facebook.
There have been months — or is it years now? — of bad news about the social network. Last month, Facebook revealed that a security vulnerability exposed up to 50 million accounts to being hijacked by hackers. Through the vulnerability, a hacker could take over your account — meaning anything you ever posted on Facebook, or even apps that you connected with using your Facebook account, could have been infiltrated.
The company said in a statement that it was investigating the incident and would share updates. “People’s privacy and security is incredibly important, and we’re sorry this happened,” the company said Wednesday. “It’s why we took immediate action to secure people’s accounts and fix the vulnerability.”
The breach followed a scandal involving Cambridge Analytica, the voter-profiling firm that got its hands on the private data belonging to millions of Facebook users. And maybe you are just tired of the partisan yammering and updates from the six-degrees-of-friends.
I have some firsthand experience with all of this. After the disclosure of Facebook’s breach, I felt my trust in the social network was broken. So I pulled out my data from Facebook and purged the account. What I found out about the process: The more you have integrated Facebook into your life, the more time-consuming it will be to delete it.
To make account deletion as painless as possible, here is a step-by-step guide. I also included steps on breaking up with Instagram, Facebook’s photo-sharing app, for those looking for a cleaner getaway.
Before you commit to breaking up with Facebook, it’s important to handicap the potential collateral damage. Some products and services are deeply integrated with Facebook and could become difficult to use without the social networking account.
The quickest way to test the waters is to deactivate your Facebook account, which is essentially an account suspension that can immediately be reversed. To deactivate, you simply click through your settings and select “Manage Your Account.” Then click the button marked “Deactivate your account.”
When I did that, I noticed I could no longer run Instagram ads to promote my dog’s Instagram account because the advertising tools are directly tied to Facebook. So if you are a business owner who advertises products on Instagram, deleting Facebook would cut off that marketing channel.
Deactivating my account also broke access to apps and websites that I used my Facebook account to sign up for. I found I could no longer easily get into Pinterest because I had used my Facebook account to register for the virtual scrapbooking service. To regain access, I reactivated my Facebook account and then went into my Pinterest settings. Once there, I disconnected the Pinterest account from Facebook and reset my Pinterest password. Then I logged back in to Pinterest with my email address instead.
For other apps, like Spotify and ChefSteps, I similarly disconnected the apps from my Facebook account. Then I reset the passwords for those services to regain access with my email address.
Doing all of that was a pain. But the exercise was worth it to ensure I wouldn’t break my accounts for other sites.

Stadsängar bättre alternativ än gräsmattor

Större delen av städernas grönytor utgörs av gräsmattor. I en ny artikel i vetenskapstidskriften Science lyfter forskare vid Sveriges Lantbruksuniversitet fram bättre och mer långsiktigt hållbara alternativ med mer varierad växtlighet, till exempel ängsliknande miljöer.
SLU:s tvärvetenskapliga forskningsprojekt LAWN visade att gräsmattor utgör så mycket som 40-60 procent av grönområden i svenska städer. Totalt täcks cirka 23 procent av städerna av gräsmattor.
Klippta gräsytor dominerar städers grönytor världen över. De fyller många viktiga funktioner, så kallade ekosystemtjänster. Förutom utrymme för lek och fritidsaktiviteter och skönhetsupplevelser producerar de syre, motverkar jorderosion, tar hand om vattenflöden och håller nere växthusgasutsläpp genom att lagra in kol.

På många håll är gräsmattorna dock så intensivt skötta att de positiva effekterna för miljö och klimat helt försvinner på grund av utsläpp från motorgräsklippare, användning av konstgödnings- och bekämpningsmedel och konstbevattning. I torra regioner av USA står bevattningen av gräsmattor för 75 procent av hushållens totala vattenkonsumtion.



Örtgräsmattan är den största alternativa gräsmattan på SLU:s Campus Ultuna. 


Ökad biologisk mångfald

Traditionella gräsmattor består av ett fåtal arter och på många håll har de bidragit till spridning av för miljön främmande, så kallat invasiva, arter. Mer ängslika miljöer ger ökad biologisk mångfald och bättre livsutrymme för fler arter. Exempelvis pollinatörer som bin och fjärilar har väldigt små möjligheter att livnära sig i en vanlig bruksgräsmatta.
I artikeln i Science rekommenderar forskarna en övergång till mer hållbara alternativ som bryter mot den förhärskande normen. Studier både i Storbritannien och Sverige visar att människor gärna byter ut monotona gräsmattor mot mer varierade miljöer och i Berlin finns exempel på naturparker med mer vild vegetation som tagits emot väl av invånarna.


På SLU:s Campus Ultuna har man anlagt försöksytorna ÖrtgräsmattanDen svenska ängen och Äng med picknickbänk. Där finns också mindre försöksytor med namn somKalkängenMålerisk äng och Fjärilsparadiset. Projektet LAWN har också producerat handboken Alternativ till gräsmatta – från teori till praktik.

What You Need to Know About Boeing’s 737 Max


This popular passenger jet was recently involved in the Lion Air fatal crash. If you’re worried about flying one on your next trip, here is a quick guide to the plane and the airlines that fly it.


The Boeing 737 Max, which the company unveiled in 2017, quickly became one of its most popular planes: 200 Maxes bought by airlines ranging from American to Southwest, are already in the air and more than 4,700 are currently on order.
But, in the wake of the fatal Lion Air accident in Indonesia last month that killed all 189 people on board, and which investigators have suggestedmight have been caused in part by problems with the 737 Max 8 that was flying that route, some travelers may be wondering about these planes. To be clear: The investigation into the crash is still ongoing, and investigators have not made any announcements saying there are problems with the entire fleet of Maxes. But until the investigation is fully concluded, some passengers may still be nervous. Here’s some basic information about the Max and tips on how to find out if you’re scheduled to travel on one on your next trip.
It’s the latest generation of the Boeing 737, a kind of aircraft that’s been flying since the 1960s. There are four kinds of Maxes in the fleet, numbered 7, 8, 9 and 10. The 8 series, which was involved in the crash in Indonesia, has been flying the longest; the first one entered service in May of 2017. Max 9s are also now flying passengers, but the 7s and 10s are still in development phases.
The 737 Max is mostly used for short- and medium-distance flights, but a few airlines also fly it between Northern Europe and the East Coast of the United States. It is more fuel efficient and has a longer range than earlier versions of the 737.
It is Boeing’s best-selling plane, so, of course, many do. In the United States, American Airlines, Southwest Airlines and United Airlines are all operators, using it on routes like Miami-New York and Dallas-Chicago. Other major carriers in Canada and Mexico — as well as roughly two dozen airlines across Europe, South America, Asia and Africa (including Icelandair, Aerolíneas Argentinas, LOT Polish Airlines and Air China) — have Maxes in their fleets.
Most airlines let you see the aircraft type as you’re booking your travel online. On Southwest’s website, for example, you can find out what kind of plane will be used on your trip by clicking the flight number on the page where prices and flight times are displayed. A pop-up will appear with information about the scheduled aircraft, along with details about in-flight amenities and statistics on how likely that particular flight is to be delayed. Southwest is one of the largest current operators of the 737 Max 8, with 26 in its fleet. (The carrier operates a total of 746 planes, all of which are 737 variants.)
You can also find out what kind of plane is being used for your flight on seatguru.com. If you enter your flight number or route and the date you’ll be traveling, the website will tell you what kind of plane is going to be used, and whether yours is a 737 Max. But just to reiterate, these planes are still certified as airworthy by aviation’s governing bodies.

SPACE WEATHER IN WARTIME--

A SUNSPOT TRIGGERS NAVAL MINES:  
Researchers studying declassified Naval records have found evidence that a big sunspot may have caused dozens or perhaps even thousands of naval mines to explode off the coast of Vietnam in 1972. The solar storms of August '72 were already legendary at NASA. These new findings suggest that the event might have been even more potent than previously thought.

Men and women of all classes of society joining in uproarious demonstrations, cheering, singing and flag waving in the Place de la Concorde, Paris.” Dec. 12, 1918

Det finns många kostråd och ännu fler pekpinnar om vad som är bra att äta och att dricka, både ur ett hälsoperspektiv och för miljöns skull. Här är 7 livsmedel du alltid ska försöka undvika /"Mitt Kök")

Krossade linfrön

Linfrön har debatterats mycket, och de krossade linfröna har Livsmedelsverket gått ut med en varning om.
De avråder helt från att äta krossade linfrön, då linfrön innehåller ämnen som kan bilda vätecyanid, och när fröna är krossade blir innehåller i fröna mer tillgängliga för kroppen. Det ökar alltså risken för att få i sig skadliga mängder vätecyanid, skriver Livsmedelsverket.
Hela linfrön rekommenderas att man inte äter mer än en till två matskedar per dag för att undvika att få i sig dåliga ämnen.


Produkter med palmolja

Palmoljan finns i många produkter och matvaror; som till exempel chokladkakor, kex, chips, bröd och pepparkakor. Palmoljan innehåller en hög mängd mättat fett, vilket kan öka risken för hjärt-kärlsjukdomar, skriver Livsmedelsverket. 
Förutom att den är dålig för hälsan, är palmoljan inte heller bra för miljön. Oljepalmsplantager förstör natur, och du som konsument kan be om ansvarsfullt producerad palmolja.

Fisk med höga halter av miljöföroreningar

Vissa fiskar innehåller farliga mängder miljöföroreningar, som kvicksilver, PCB:er och dioxiner. Dioxiner och PCB finns i fet fisk som till exempel öring, strömming, vildfångad lax från Östersjön.
Även röding från Vättern och öring och sik från Vänern kan innehålla höga halter av dioxin och PCB. Poly- och perfluorerade alkylsubstanser (PFAS) kan finnas i fisk som kommer från sjöar som är förorenade av PFAS, skriver Livsmedelsverket.


Jätteräkor

Jätteräkor, scampi, tigerräkor eller gambas. Oavsett vad de kallas så är jätteräkan inte det bästa valet du kan göra. Den är en stor miljöbov, och industrin bakom odling av jätteräkor förstör naturen och påverkar vårt klimat.
Naturskyddsverket har under de senaste åren genomfört kampanjer som uppmanade butiker och restauranger att sluta sälja och servera jätteräkor. Även konsumenter uppmanas att tänka på vad för konsekvenser det blir av att du festar loss på scampi. Bland annat tömmer odlingarna haven på viktig fisk, och räkodlingarna har också förstört viktig mangroveskog som påverkar naturen.
Välj istället vanliga räkor, helst fiskade så nära ditt hem som möjligt så gör du miljön en tjänst.

Ål

Ålen är rödlistad, något den varit sedan 2005, och sedan 1950-talet har mer än 97 procent av glasålsbestånd som tidigare kunnat mätas vid Europas kuster försvunnit, skriver Naturskyddsverket.
Ålen är alltså akut hotad, och kan försvinna för alltid. Naturskyddsföreningen vill se ett totalt ålfiskestopp och det bästa vore om vi som konsumenter slutar att köpa och äta ål.

För mycket rött kött

Lagom är bäst, brukar det heta. Och det stämmer in i många kostråd också. Rött kött rekommenderar Livsmedelsverket att man ska äta max 500 gram av i veckan. Med rött kött menas kött från gris, lamm, ren, vilt och nöt.
Om man äter mindre än 500 gram rött kött i veckan minskar man risken att drabbas av tjock-ändtarmscancer, och särskilt viktigt verkar det vara att dra ner på chark som innehåller mycket mättat fett och salt. En minskad charkkonsumtion minskar också risken för hjärt-kärlsjukdom, exempel på charkprodukter kan vara rökt skinka, kassler, korv, salami eller leverpastej.

Läsk och andra sötade drycker (värst av allt enligt mig Stig)
Det är ingen chock att läsk som Coca-Cola, Fanta eller Sprite innehåller mycket socker. Coca-Cola innehåller 10,6 gram socker per 100 ml, vilket motsvarar 3,5 sockerbitar (3 g sockerbitar). En burk på 33 cl innehåller alltså cirka 10 sockerbitar.

Socker är en stor hälsobov, och påverkar din kropp. Enligt de nordiska näringsrekommendationerna, NNR 2012 bör mindre än 10 procent av energin från maten komma från tillsatt socker.

Var medveten om hur mycket socker du får i dig via dryck, och välj hellre smaksatt vatten.
