Saturated fats raise total blood cholesterol as well as significantly raise LDL cholesterol (the bad cholesterol). They are mainly found in animal fats and dairy, tho I wouldn't give up good meat to avoid them. I would, however, try really hard to buy products without palm oil in them.
As you said, trans fats are basically created in the laboratory durring the process of hydrogenation and should be strongly avoided at all costs
heres a quote from a recent study by the European Journal of Clinical Nutrition
"When replacing saturated fat with either n-6 polyunsaturated fat or monounsaturated fat, total fat intakes decreased by 2.9% energy and 5.1% energy, respectively. Replacing saturated fat with n-6 polyunsaturated fat (trial I) lowered plasma total cholesterol by 19% [from 4.87 (0.88) to 3.94 (0.92) mmol/l, mean (s.d.)], low density lipoprotein cholesterol by 22% [from 2.87 (0.75) to 2.24 (0.67) mmol/l], and high density lipoprotein cholesterol by 14% [from 1.39 (0.36) to 1.19 (0.34) mmol/l], whereas replacing saturated fat with monounsaturated fat (trial II) decreased total cholesterol by 12%, low density lipoprotein cholesterol by 15%, and high density lipoprotein cholesterol by 4%, respectively. The change in the ratio of total to high density lipoprotein cholesterol was similar during trial I and trial II." | So anyway, you are correct in that unsaturated fats (the good kind) can lower LDL levels, without raising HDL livels. That is fine, but then you have to realize that saturated fat, while it does increase LDL levels, it also increases HDL. And it does so by a significant margin.
Furthermore, you need to realize that there are different types of LDL - the small, compact kind that is difficult for our bodies to handle (found in disgusting chemically treated oils and "vegetable" oil), and the big 'fluffy' kind that is essentially harmless and easily transported in the blood. The kind that doesn't stick around any longer than it should. The kind of LDL that is in good saturated fat is the 'fluffy' kind, and is harmless.
So while saturated fat indeed increases your "total amount" of cholesterol, your actual profile will be significantly improved. And most importantly, your ratio of HDL to triglycerides (the most important aspect of blood profile of all) is improved by a huge margin.
Avoiding saturated fat is not only pointless and ignorant, it's unhealthy. |
