Both coffee and tea may be effective weapons against diabetes, researchers at the University of Sydney in Australia have found
The study indicated that each daily cup of coffee or tea may reduce a person’s risk of Type 2 diabetes by up to 7%, regardless of whether caffeine is present or not.
Researchers studied data from over 30 previous studies involving almost a million participants.
Caffeine can slow the growth of brain tumor cells according to researchers led by Kang Sang-soo of Gyeongsang National University and C. Justin Lee of the Korea Institute of Science and Technology in Seoul, South Korea.
The research team, comprising scientists from Seoul National University, Gyeongsang National University, and Emory University in Atlanta, said that animal test results showed regular caffeine found in coffee and green tea to have "strongly repressed the growth of inositol trisphosphate receptor (IP3R) closely linked to glioblastoma, which is the most common and aggressive type of primary brain tumour found in humans," adding that calcium plays a primary role in spreading glioblastoma tumour cells in humans, and that IP3R directly contributes to the amount of calcium released.
The Nestlé Research Center has announced in The Journal of Nutrition that its researchers have discovered that adding milk to instant coffee "does not reduce the bioavailability of antioxidants."
Drinking instant coffee with or without milk produced the same uptake levels of coffee’s antioxidants, including caffeic acid, ferulic acid and isoferulic acid, according to the findings, which are based on a study of nine participants.
"Up until now there has been very little known about how proteins, especially from milk, influence the bioavailability and efficacy of coffee antioxidants," said Mathieu Renouf, lead researcher from Nestlé Research Center in Lausanne. "Our study is the first to show that coffee antioxidants are just as bioavailable in coffee with milk as they are in black coffee."
Men that drink more than two cups of tea daily are trimmer than those that don’t, according to a study presented at the First International Congress on Abdominal Obesity. Researchers examined the relationship between coffee and tea drinking and abdominal obesity in 3,823 adults who participated in the 2003-2004 US National Health and Nutrition Examination Survey.
Previous studies have looked at coffee and tea drinking habits and obesity in general, but little is known about how these habits affect abdominal obesity.
Its probably NOT what the antismoking lobbyists wanted to hear, but it seems that drinking green tea may significantly reduce a smoker’s chances of contracting cancer, according to a recent Taiwanese study.
Lin Yi-hsin, a student from the Graduate School of Public Hygiene at Taiwan’s Chung Shan Medical University, recruited 500 people, including 170 lung cancer patients, for her study.
"I analysed their lifestyles and habits of smoking, eating and drinking tea," she told a news conference at her university in Taichung, central Taiwan.
Tea may protect against endometrial cancer, but researchers caution that more research is needed to establish if there is a real benefit.
Endometrial cancer forms in the lining of the uterus and is the fourth most common cancer in American women, with 42,000 new cases and nearly 7,800 deaths reported annually.
Researchers from the National Shanghai Center for New Drug Safety Evaluation and Research in China analyzed several published studies and examined the role of green and black tea in the prevention of endometrial cancer.
