Are You Eating Too Much Protein?
Caloric restriction (CR) has long been known to increase longevity (often dramatically) in a number of eukaryotic models, including yeast, fruit flies, nematodes, mice, and rhesus monkeys. It's also well established that protein restriction can reduce cancer incidence and/or increase longevity in many organisms, independently of calorie intake.
Recent research by a multinational team (including scientists from Ecuador, Italy, and the United States) now indicates that restricting protein intake may be sufficient to reduce cancer in humans substantially. A new study in Cell Metabolism (4 March 2014), drawing on epidemiological data involving 6,381 U.S. men and women aged 50 and above (from the NHANES III database), has found that persons aged 50–65 reporting high protein intake had a 75% increase in overall mortality and a four-fold increase in cancer death risk during an 18-year period. (However, high protein intake was associated with reduced cancer and overall mortality in respondents older than 65.) A five-fold increase in diabetes mortality, across all age groups, was also noted for those reporting high protein intake.
According to the authors of the study:
None of these associations was significantly affected by controlling for percent calories from total fat or for percent calories from total carbohydrates. However, when the percent calories from animal protein was controlled for, the association between total protein and all-cause or cancer mortality was eliminated or significantly reduced, respectively, suggesting animal proteins are responsible for a significant portion of these relationships. When we controlled for the effect of plant-based protein, there was no change in the association between protein intake and mortality, indicating that high levels of animal proteins promote mortality and not that plant-based proteins have a protective effect.
The authors conclude (among other things) that "a diet in which plant-based nutrients represent the majority of the food intake is likely to maximize health benefits in all age groups." They suggest that a daily adult protein intake of 0.7 to 0.8 g per kilogram of body weight, currently considered a minimum acceptable amount, should in fact be considered the proper target amount—all of it as plant protein, not animal protein.

Best case: redrawing borders leads to peace, prosperity and EU membership. But there's also a worst case
- The Yugoslav Wars started in 1991, but never really ended
- Kosovo and Serbia are still enemies, and they're getting worse
- A proposed land swap could create peace - or reignite the conflict
The death of Old Yugoslavia

Wars are harder to finish than to start. Take for instance the Yugoslav Wars, which raged through most of the 1990s.
The first shot was fired at 2.30 pm on June 27th, 1991, when an officer in the Yugoslav People's Army took aim at Slovenian separatists. When the YPA retreated on July 7th, Slovenia was the first of Yugoslavia's republics to have won its independence.
After the wars

Map of former Yugoslavia in 2008, when Kosovo declared its independence. The geopolitical situation remains the same today.
The Ten-Day War cost less than 100 casualties. The other wars – in Croatia, Bosnia and Kosovo (1) – lasted much longer and were a lot bloodier. By early 1999, when NATO had forced Serbia to concede defeat in Kosovo, close to 140,000 people had been killed and four million civilians displaced.
So when was the last shot fired? Perhaps it wasn't: it's debatable whether the Yugoslav Wars are actually over. That's because Kosovo is a special case. Although inhabited by an overwhelming ethnic-Albanian majority, Serbians are historically very attached to it. More importantly, from a legalistic point of view: Kosovo was never a separate republic within Yugoslavia but rather a (nominally) autonomous province within Serbia.
Kosovo divides the world

In red: states that recognise the independence of Kosovo (most EU member states – with the notable exceptions of Spain, Greece, Romania and Slovakia; and the U.S., Japan, Turkey and Egypt, among many others). In blue: states that recognise Serbia's sovereignty over Kosovo (most notably Russia and China, but also other major countries such as India, Brazil, Mexico, South Africa and Iran).
The government of Serbia has made its peace and established diplomatic relations with all other former Yugoslav countries, but not with Kosovo. In Serbian eyes, Kosovo's declaration of independence in 2008 was a unilateral and therefore legally invalid change of state borders. Belgrade officially still considers Kosovo a 'renegade province', and it actually has a lot of international support for that position (2).
The irony is that on the longer term, both Kosovo and Serbia want the same thing: EU membership. Ironically, that wish could lead to Yugoslav reunification some years down the road – within the EU. Slovenia and Croatia have already joined, and all other ex-Yugoslav states would like to follow their example. Macedonia, Montenegro and Serbia have already submitted an official application. The EU considers Bosnia and Kosovo 'potential candidates'.
Kosovo is the main stumbling block on Serbia's road to EU membership. Even after the end of hostilities, skirmishes continued, between the ethnically Albanian majority and the ethnically Serbian minority within Kosovo, and vice versa in Serbian territories directly adjacent. Tensions are dormant at best. A renewed outbreak of armed conflict is not unthinkable.
Land for peace?
Mitrovica isn't the only area majority-Serb area in Kosovo, but the others are enclaved and fear being abandoned in a land swap.
In fact, relations between Kosovo and Serbia have deteriorated spectacularly in the past few months. At the end of November, Kosovo was refused membership of Interpol, mainly on the insistence of Serbia. In retaliation, Kosovo imposed a 100% tariff on all imports from Serbia. After which Serbia's prime minister Ana Brnabic refused to exclude her country's "option" to intervene militarily in Kosovo. Upon which Kosovo's government decided to start setting up its own army – despite its prohibition to do so as one of the conditions of its continued NATO-protected independence.
The protracted death of Yugoslavia will be over only when this conflict is finally resolved. The best way to do that, politicians on both sides have suggested, is for the borders reflect the ethnic makeup of the frontier between Kosovo and Serbia.
The biggest and most obvious pieces of the puzzle are the Serbian-majority district of Mitrovica in northern Kosovo, and the Albanian-majority Presevo Valley, in southwestern Serbia. That land swap was suggested previous summer by Hashim Thaci and Aleksandar Vucic, presidents of Kosovo and Serbia respectively. Best-case scenario: that would eliminate the main obstacle to mutual recognition, joint EU membership and future prosperity.
If others can do it...

Belgium and the Netherlands recently adjusted out their common border to conform to the straightened Meuse River.
Sceptics and not a few locals warn that there also is a worst-case scenario: the swap could rekindle animosities and restart the war. A deal along those lines would almost certainly exclude six Serbian-majority municipalities enclaved deep within Kosovo. While Serbian Mitrovica, which borders Serbia proper, is home to some 40,000 inhabitants, those enclaves represent a further 80,000 ethnic Serbs – who fear being totally abandoned in a land swap, and eventually forced out of their homes.
Western powers, which sponsored Kosovar independence, are divided over the plan. U.S. officials back the idea, as do some within the EU. But the Germans are against – they are concerned about the plan's potential to fire up regional tensions rather than eliminate them.
In principle, countries consider their borders inviolate and unchanging, but land swaps are not unheard of. Quite recently, Belgium and the Netherlands exchanged territories so their joint border would again match up with the straightened course of the Meuse river (3). But those bits of land were tiny, and uninhabited. And as the past has amply shown, borders carry a lot more weight in the Balkans.
