Cholesterol should be high, especially HDL. Triglycerides are meant to be low especially in relation to HDL. The supposed link between cholesterol and heart disease is bogus and based on completely fraudulent science in order to sell drugs and modern profitable foods. The reason for this claim is that animal foods are the only way to have healthy high levels of HDL so demonising cholesterol is the main way they demonise animal foods and promote modern crap. This has been known for decades. If you are older it would be extremely dangerous to lower your cholesterol. Low cholesterol is strongly linked with shorter life expectancy and higher all cause mortality.
