Researchers at the George Institute for International Health (Sydney, Australia), the University of Glasgow (United Kingdom), and other institutions conducted a systematic review and meta-analysis investigating the association among coffee, decaffeinated coffee, and tea consumption with the risk of diabetes mellitus. The meta-analysis included data obtained from 18 studies that reported on the association between coffee consumption and diabetes; six studies that reported estimates of the association between decaffeinated coffee and diabetes; and seven studies that reported on the association of tea.
The results of the pooled meta-analysis found that drinking coffee was inversely related to risk of diabetes (more coffee was linked to lower risk). After adjusting for potential confounders, every extra cup of coffee consumed in a day was linked to a 7% reduction in the excess risk of diabetes; drinking 3 to 4 cups per day was linked to a 25% lower risk than drinking none or up to two cups per day. In those studies that assessed decaffeinated coffee consumption, drinking more than 3 to 4 cups a day was linked to about one third lower risk of diabetes, compared to none. Drinking more than 3 to 4 cups of tea per day was linked to a one fifth lower risk of diabetes, compared to non-tea drinking. The authors suggested the effect of tea and coffee consumption on diabetes risk could be due to direct biological effects, since their apparent protective effect appears to be independent of potential confounding variables, and could partly be due to other compounds present in tea and coffee, such as magnesium, or antioxidants such as lignans or chlorogenic acids. The study was published in the December 14, 2009, issue of the Archives on Internal Medicine.
“If such beneficial effects were observed in interventional trials to be real, the implications for the millions of individuals who have diabetes mellitus, or who are at future risk of developing it, would be substantial,” concluded first author Rachel Huxley, M.D., of the George Institute, and colleagues. “It could also be envisaged that we will advise our patients most at risk for diabetes mellitus to increase their consumption of tea and coffee in addition to increasing their levels of physical activity and weight loss.”

Jika selama ini kopi hanya dikenal sebagai teman begadang karena kandungan kafeinnya, mungkin kini saatnya Anda tahu khasiat lain dibalik si hitam ini. Sebuah penelitian ilimiah yang di lakukan para pakar di Amerika Serikat menyebutkan bahwa kopi kemungkinna besar memberikan efek positif bagi kesehatan lebih besar dari pada mengkonsumsi buah-buahan dan sayuran
Pdpersi, Jakarta - Masalah kebotakan pada kaum laki-laki 80- 90% disebabkan oleh faktor genetika. Sedangkan pada kaum perempuan biasanya tidak mengalami kebotakan tetapi lebih kepada penipisan rambut. ”Jadi bukan karena stres seperti yang kerap disangka oleh sebagian orang. stres hanya memperberat permasalahan tersebut," ujar Dr Gunawan Budi Santoso, SpKK dalam sebuah diskusi di Jakarta, kemarin. Meski demikian, menurut Dr Gunawan, bukan berarti bahwa setiap anak atau keturunan orang yang menderita kebotakan akan mengalami permasalahan yang sama. ”Sebab ada orang yang bersifat hanya sebagai carrier atau pembawa. Bila ada orang yang mengalami kebotakan tetapi orang tuanya tidak, mungkin saja kebotakan itu dialami oleh kakeknya," paparnya. Dia menambahkan, kerontokan rambut yang mengarah kepada kebotakan biasanya dialami seseorang mulai usia 20 tahun ke atas. Selain genetik, kata Dr Gunawan, faktor penyebab kerontokan rambut antara lain karena terkena luka bakar, sedang menjalani kemoterapi, atau bisa juga karena ketombe atau ketidakcocokan dengan sampo. ”Untuk mengobati kerontokan rambut, harus dilihat pula penyebab dari kerontokan tersebut sehingga solusi yang diberikan tidak selalu melakukan transplantasi rambut,” ujar Dr Gunawan.
