I invite you to read this recent blogpost by Dr Briffa. Dr Briffa is a UK medical doctor with a particular interest in good nutrition and its rôle in good health. As you will see, Dr Briffa's article should reassure you that eating saturated fat will not cause heart disease, and indeed that eating saturated fat is associated with reduced risk of death from cardiovascular disease.
My own hobby horse with regard to food is, of course, that reducing salt/sodium intake benefits every aspect of your health, including every aspect of heart health, as well as reducing excess weight in people who are unfortunate enough to be overweight or obese. See safe weight loss by eating less salt and Sodium in Food.
