A study suggests, eating processed meat such as sausages increases the likelihood of heart disease, while red meat does not seem to be as harmful. <br/><br/>A Harvard University team which looked at 20 studies involving over one million people found just 50g of processed meat a day also raised the risk of diabetes. <br/><br/>But there was no such risk from eating even twice as much unprocessed meat, such as beef, lamb or pork. This was despite the fact the two forms of meat have a similar fat content. <br/><br/>The study by the team from Harvard School of Public Health involving more than one million participants from 10 countries appears in the journal Circulation. <br/><br/>Victoria Taylor, senior heart health dietician at the British Heart Foundation, said if you like red meat, this can still be included as part of a balanced heart-healthy diet. <br/><br/>However, he suggested further research was needed before any dietary recommendations could be made.
