and from what i have been reading they are more than likely to have one than someone with high cholesterol.
What have you been reading?
How long had your husband's cholesterol been that low? decades of artery clogging would take time to reverse. Very high blood pressure and smoking can also increase the rate at which the plaque sticks to the arteriol walls. Does he have a history of clotting problems?
What kind of hear disease does your husband have? Also, what is the break down in your husband's numbers? ldl, hdl, lipids? That all makes a difference as well. Increasing HDL is good, but if total cholesterol is indeed that low, then I doubt (in my layperson opinion) that raising HDL's would have a significant impact.
I am not sure what you are reading. I am all in favor of taking charge of your health and knowing as much as you can about your health. Doctors don't always know everything. But please explore the claims made by some of these sources you are reading. You can read abstracts from just about any medical journal article here: http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=PubMed
You can search by keywords, etc.
Also, another excellent guide that should be a part of anyone's research is: http://www.nlm.nih.gov/medlineplus/medlineplus.html
There are a lot of alternative health gurus out there, and some are more credible than others. If you don't trust your doctor's opinion, get another opinion. Consider a trip out to Cleveland where the #1 heart center is.http://www.clevelandclinic.org/heartcenter/
I wish you both the best of luck.
Peebs: As far as eating cholesterol, hasn't it been well established that it is eating saturated and trans fats and not cholesterol that impacts blood levels?
for example: http://www.hsph.harvard.edu/nutritionsource/fats.html
On genetics- there are some people with naturally low or naturally high cholesterol levels, but that does not mean everyone's levels are genetically influenced so strongly, and it surely does not mean that we are slaves to our genes. (like with so many other things)
