Avoid eating red meat twice daily or face a 30 percent higher risk of heart disease, says a study about women.
Substituting red meat with fish cuts heart disease risk by 24 percent while replacing red meat with chicken lowered it by 19 percent, the survey found.
Researchers at the Harvard School of Public Health in Boston, US, studied the diets of 84,136 women aged 30 to 55 years between 1980 and 2006, reports the
Participants were told to fill in a questionnaire specifying how often they ate 116 different food items.
During the research period, 2,210 suffered non-fatal heart-attacks, while 952 others died from coronary heart disease.
Study author Adam Bernstein said: "Our study shows that making substitutes for red meat or minimising the amount of red meat in the diet has important health benefits."
