Summary

Studies suggest that the link between saturated fat consumption and heart disease may not be as straightforward as once thought, and that other factors, such as the overall diet and lifestyle, may play significant roles. In today's show we dive into these details.

Study Mentioned

Souza, R. J. de et al. Intake of saturated and trans unsaturated fatty acids and risk of all cause mortality, cardiovascular disease, and type 2 diabetes: systematic review and meta-analysis of observational studies. BMJ : Br. Méd. J. 351, h3978 (2015).

Harcombe, Z. et al. Evidence from randomised controlled trials did not support the introduction of dietary fat guidelines in 1977 and 1983: a systematic review and meta-analysis. Open Hear. 2, e000196 (2015).

Time Stamps

00:00 There is no evidence that a low saturated fat diet improves or reduces cardiovascular disease.

03:10 Trans fats are problematic.

05:30 Government dietary advice initially focused on reducing fat and saturated fat consumption.

07:15 Randomized control trials done before government recommendations showed no statistical difference in mortality.

09:30 The control group in the Rose Corn Oil Study had a lower death rate than the intervention group.

11:50 Mean serum cholesterol levels were higher in the intervention groups but did not result in significant differences in cardiovascular disease or all-cause mortality.

14:00 At the time dietary advice was introduced despite having no evidence to support it.

15:30 More than 600,000 people die from cardiovascular disease every year.

0:00.0	For the past 35 years, dietary fat, specifically saturated fat has been demonized.
0:04.5	We have dietary recommendations and guidelines that support the consumption of a low-fat diet.
0:09.3	But in today's show, we're going to review six randomized controlled trials that do not support the dietary
0:15.2	guidelines that have been foisted upon over 330 million Americans and about
0:19.4	60 million people in the United Kingdom drawing upon two recently published
0:24.2	analysis of randomized controlled trials and I want to really break this down
0:29.1	because still so many people are scared of butter, scared of saturated fat, and are swapping out
0:34.6	saturated fat and replacing that either with industrialized seed oils or
0:39.8	carbohydrates like sugar. And I think it's important to acknowledge that there's really no
0:43.9	evidence from randomized controlled trials showing that when you consume a low
0:48.4	fat and specifically a low saturated fat diet that there's any improvement or significant reduction in
0:54.9	cardiovascular disease and cardiovascular disease mortality. The first paper that
0:58.9	we're going to talk a lot about today is titled, Evidence from Randomized
1:02.2	Control Trials
1:03.0	Do Not Support the Introduction of Dietary Fat Guidelines
1:05.9	in 1977 and 1983, a systematic review and met analysis.
1:11.1	Essentially, what these authors did is they looked at all of the
1:14.5	different randomized controlled trials where individuals were randomized to
1:19.0	either have a low saturated fat diet or a control group and there's really weak if and barely any evidence
1:25.8	supporting and by the way these trials part of the inclusion criteria was that they
1:30.7	lasted for more than a year.
1:32.5	And so mortality and events were part of the outcomes here.
