Do omega 3 in nuts, sapn, etc raise hdl? if so, the fish oil should as well right?

Don't focus here: The evidence on omega-3's as offering protection from atherosclerosis . Heart disease / stroke is unclear at best. I think your own physician and most of us here would urge you instead to look at lifestyle considerations (diet, fitness) instead of what kinds of oils are in nuts. Reading speculative stuff / slick promotions is fun but no substitute for real hard work that will help you.

Yes, however...: Yes, tree nuts raise hdl, as does fish oil, olive oil, red wine & exercise- see http://www.Ehow.Com/how_5205513_increase-good-cholesterol-hdl.Html while raising HDL is beneficial & does reduce risk of heart disease, the most important strategy to decrease risk is to reduce inflammation- see http://www.Cbn.Com/cbnnews/healthscience/2012/october/cholesterol-myth-what-really-causes-heart-disease/.
