I have found sticking to a low fat diet is the best thing i can do to keep my low, mine is really good , but my mother has high cholesterol and it appears to be the hereditary kind, she too was fine at my age, so i really have to keep an eye on it, we have different readings here in low numbers so i have no idea whether your's is way too high or not, but remember it depends on the good cholesterol and bad cholesterol readings(cannot remember them right now like the HDL or something) more than just one figure.
