A single daily glass of wine or beer raises the risk of premature death by a fifth, researchers have said.
Many previous studies have shown that light drinking can have health benefits, but the latest suggestion is that these are outweighed by the dangers.
Sarah Hartz, an assistant professor of psychiatry in the UK, said drinking can help prevent some heart-related problems.
But she added that a daily tipple increased cancer risk and, as a result, mortality rates.
“Consuming one or two drinks about four days a week seemed to protect against cardiovascular disease, but drinking every day eliminated those benefits,” she said.
