My 30 year old brother had a cholesterol check and came back at 7.9, he was told to go on a low cholesterol diet. He exercises often and is not over weight. I am 35 & decided to get mine checked, it came back at 5.6 & I too was told to go on a low cholesterol diet, I am about 1 stone over weight but regularly exercise (ran a marathon 2 months ago!) My other brother, 33 years old, had his checked and was even higher than my other brother. He is very slim & exercises regularly. His doctor told him not to worry about it and carry on as he is! His diet is a lot poorer than mine, i cook everything from scratch etc. What are your thoughts on this?
