Trans fatty acids are a side product of the partial hydrogenation of plant oil. According to the National Academy of Sciences, “trans fatty acids are not essential and provide no known benefit to human health.” In fact, trans fats decrease levels of HDL ‘good’ cholesterol and increase levels of LDL ‘bad’ cholesterol in the body. This directly increases a person’s risk of heart disease and stroke...
...metabolic problem that has been clearly associated with disease. If the tests suggest the customer has a gene that promotes, say, a bad cholesterol profile, it can tell that person, based on his dietary and lifestyle profile, how to modify his diet and habits to keep his good (HDL) and bad (LDL) cholesterol in healthy balance. Ditto for other genetic markers. Sciona, says Gill-Garrison, makes sure that each nugget of advice it offers is built on a firm scientific foundation. And a bibliography on the company?s web site, she says, backs up that claim...
Would a high-fat diet be particularly damaging to your health, given your genetic makeup? About 15% of folks are born with a form of a liver enzyme that causes their HDL, or good cholesterol, level to go down in response to dietary fat. In most people the HDL level goes up, counterbalancing some of the bad effects of dietary fat on LDL--the dangerous cholesterol...
...HDL, LDL and triglycerides aren't quite the whole story either. Over the past few years, researchers have identified yet another form of fat that could rightly be labeled Bad Cholesterol II. Called lipoprotein (a), or Lp(a), it behaves like LDL in the body. But because Lp(a) levels have more to do with your genes than your diet, they can't easily be controlled. At best, doctors think they can use Lp(a) screening to find people who should be working extra hard to reduce their other heart-attack risks...
Some studies have also shown that exercise raises HDL levels; that it increases the volume of plasma (blood's liquid component), thinning the blood and thus keeping dangerous clots at a minimum; and that it may boost levels of an enzyme that vacuums cholesterol and fatty acids from the blood...
