Balance of good fats & bad fats can aid in good cardiac health
Scientists from University of Cambridge examined the diets of 2,500 people aged 40 - 79. Results indicating that to remove all fat from your diet may not be the safest approach to could cardiac care post heart disease.
They found those who ate foods rich in omega 6 – a fatty acid present in vegetable oils, nuts and seeds – significantly reduced their risk of heart problems.
But those who had simply cut their intake of unhealthy saturated fat did not reduce their risk to the same extent.
The researchers suggest the ‘balance of fats’ in our diets could be the key to preventing coronary heart disease, which is the UK’s biggest killer.
