I just watched this video The effect of animal fats on the human body | The Real Food Channel
Dude is obviously pro vegetarian, but got my curiousity up on a couple issues...
The video is long, but the general idea was animal fat is horrible and causes clogged arteries, osteoperosis, weight gain, high blood pressure, low calcium, inflamation, colon and prostate cancer, etc. You get the point. He says BAD! (He also says we onlu need 30 or 50g protein per day :-/ )
Definately dont agree with this guy on a lot of issues, but someone shed some light if you have knowledge...
The best available current evidence is that reducing the amount of animal fats is likely to reduce incidence of heart disease. It's not easy to investigate, because of the number of other variables that affect incidence of heart disease, for example:
smoking and alcohol intake
other dietary factors
One of the best sources for this sort of thing is the Cochrane Foundation, which summarises only the best quality science in plain language. Here's one of their summary papers
This updated review suggested that reducing saturated fat by reducing and/or modifying dietary fat reduced the risk of cardiovascular events by 14% (RR 0.86, 95% CI 0.77 to 0.96, 24 comparisons, 65,508 participants of whom 7% had a cardiovascular event, I2 50%). Subgrouping suggested that this reduction in cardiovascular events was seen in studies of fat modification (not reduction - which related directly to the degree of effect on serum total and LDL cholesterol and triglycerides), of at least two years duration and in studies of men (not of women). There were no clear effects of dietary fat changes on total mortality (RR 0.98, 95% CI 0.93 to 1.04, 71,790 participants) or cardiovascular mortality (RR 0.94, 95% CI 0.85 to 1.04, 65,978 participants). This did not alter with sub-grouping or sensitivity analysis.
Few studies compared reduced with modified fat diets, so direct comparison was not possible.
The findings are suggestive of a small but potentially important reduction in cardiovascular risk on modification of dietary fat, but not reduction of total fat, in longer trials. Lifestyle advice to all those at risk of cardiovascular disease and to lower risk population groups, should continue to include permanent reduction of dietary saturated fat and partial replacement by unsaturates. The ideal type of unsaturated fat is unclear.
So, it wouldn't be right to say animal fats are the only factor involved in CHD, but the evidence points to a small but significant role.
Of course, there are other health considerations, but it's maybe best to be specific about each health concern separately.
