Researchers studied the diets of 25,639 people over 10 years Photo: PA Scientists previously knew that moderate levels of alcohol could protect against gallstones, but did not know how much was needed.
Gallstones occur when bile from the gallbladder, which is normally fluid, forms stones. |

NEW YORK (Reuters Health) - People who enjoy a glass or two of wine or beer every day could be helping to keep their bones strong, new research published in the American Journal of Clinical Nutrition suggests.
However, drinking more -- and choosing hard liquor instead of wine or beer -- may actually weaken bones, Dr. Katherine Tucker of Tufts University in Boston and her colleagues found.
In an interview with Reuters Health, Tucker agreed that keeping track of the health benefits and risks of alcohol is tough these days. "It is very confusing for people because alcohol has such diverse effects on different things," she said; for example, while drinking may prevent heart disease, it increases breast cancer risk.

If you're frying a steak and mindful of your health, then marinate it in either beer or red wine. So say food scientists who measured amounts of a family of carcinogens found in fried steaks after steeping them in booze.
Cooking food increases levels of cancer-causing compounds called heterocyclic amines (HAs). Fried and grilled meat are particularly high in these compounds, because fiery temperatures convert the sugars and amino acids in muscle tissue into HAs. Various substances can reduce HA content: olive oil, lemon juice and garlic marinade cut HAs in grilled chicken by 90 percent, while red wine reduced HAs in fried chicken.

 Scientists have discovered a grapeseed extract can force leukaemia cells to die.
Laboratory experiments show the commercially available extract caused 76% of the blood cancer cells to be destroyed within 24 hours in a process of natural self-destruction called apoptosis. All healthy cells remained unharmed.
Although the research is in its early stages and it has not been recommended people eat grapes to stave off cancer, US scientists believe the results could mark the start of promising new treatments.
It is the antioxidants in grapeseed, including resveratrol, which is known to have anti-cancer properties, that are believed to cause the cells to die.
Previous tests found that the extract was effective on skin, breast, bowel, lung, stomach and prostate cancer cells, but it this is the first time it has been tested on leukaemia.

A new insight into the reason for aging has been gained by scientists trying to understand how resveratrol, a minor ingredient of red wine, improves the health and lifespan of laboratory mice. They believe that the integrity of chromosomes is compromised as people age, and that resveratrol works by activating a protein known as sirtuin that restores the chromosomes to health.
The finding, published online Wednesday in the journal Cell, is from a group led by David Sinclair of the Harvard Medical School. It is part of a growing effort by biologists to understand the sirtuins and other powerful agents that control the settings on the living cell’s metabolism, like its handling of fats and response to insulin. |
