A diet high in red meat can shorten life expectancy, according to researchers at Harvard Medical School. The study of more than 120,000 people suggested red meat increased the risk of death from cancer and heart problems.
Substituting red meat with fish, chicken or nuts lowered the risks, the authors said. The British Heart Foundation said red meat could still be eaten as part of a balanced diet.
The researchers analysed data from 37,698 men between 1986 and 2008 and 83,644 women between 1980 and 2008.
