Dpt. of Correlation and Causation

Too Much Cola Can Cause Kidney Problems;
In a study published in the journal Epidemiology, the team compared the dietary habits of 465 people with chronic kidney disease and 467 healthy people. After controlling for various factors, the team found that drinking two or more colas a day — whether artificially sweetened or regular — was linked to a twofold risk of chronic kidney disease.

But drinking two or more noncola carbonated drinks a day, they found, did not increase the risk.

The authors of the study say more research is needed, but their findings support the long-held notion that something about cola — the phosphoric acid, for example, or the ability of cola to pull calcium from bones — seems to increase the risk of kidney stones, renal failure and other conditions affecting the kidneys.

A firm Handshake is a Measure of Health
Hand grip strength does not only provide reliable information about the health of a person. It also reveals the socio-economic status, future disability and mortality risks. It therefore permits a glance into the individual�s future. Karsten Hank and Hendrik J�rges, MEA, in cooperation with Jergen Schupp and Gert G. Wagner, DIW Berlin, merged datasets of SHARE and SOEP and analysed the grip strength of the Germans. The result: from 16 to 50 years of age, Germans squeeze so hard that exact statements about their health cannot (yet) be made. However, beyond 50 years, the decreasing muscular strength does speak volumes
