Middle-aged men who eat plenty of lean meat to get fit may inadvertently be raising their chances of heart failure, a study suggests.
Experts found too much protein from beef, chicken and pork boosts the risk of heart failure by 43 per cent for those between 42 and 60.
High-protein diets that recommend lean meats are often used by bodybuilders and praised by nutritionists to help efforts to build muscle and lose fat.
