Well, yes and no.
I have never had high bad cholesterol. I have an amazingly good level of cholesterol and get praises from my doctor.
But yes because -
There is 'bad' cholesterol and 'good' cholesterol... the bad cholesterol I'm fine... my problem is very low 'good' cholesterol. VERY low... which, according to my doctor, can only be efficiently risen by eating fish. Fish Oils, in pill form, don't work well. I tried it, for months, it did nothing.
Sadly... while my family likes fish, somewhat, they rarely if ever choose it for dinner. So I eat fish, especially salmon which is the best for raising good cholesterol levels, seldom. In the last year, for example, I have raised my good cholesterol NOT AT ALL.
When I bought my smoker I was intending to keep some smoked salmon in my refrigerator at all times... snack on it from morning til night.... but that's just another 'good habit' I failed to acquire.
