My wife described my Paleo/bulletproof diet to her Harvard trained epidemiologist friend who knows and even teaches about the Paleo diet. This epidemiologist, while having a generally positive view of Paleo, thought it was destructive to consume large amounts of butter. Does anyone know of any studies which contradicts this view?
There's still a lot of anti-saturated fat dogma out there, even among the paleo community (cough cough Loren Cordain cough cough). I think this must stem from the flawed research done in the 50's by Ancel Keyes, et al "showing" diets high in saturated fat correlated with higher incidence of heart disease. I use the quotes because the studies back then lumped saturated fat and partially hydrogenated trans fat into the same category; we know today there is a HUGE difference, but still the nutritional dogma reigns supreme.
ETA: Influence of Dairy Product and Milk Fat Consumption on Cardiovascular Disease Risk: A Review of the Evidence http://advances.nutrition.org/content/3/3/266.abstract
The findings indicate that the majority of observational studies have failed to find an association between the intake of dairy products and increased risk of CVD, coronary heart disease, and stroke, regardless of milk fat levels.
Meta-analysis of prospective cohort studies evaluating the association of saturated fat with cardiovascular disease http://www.ajcn.org/content/early/2010/01/13/ajcn.2009.27725.abstract
A meta-analysis of prospective epidemiologic studies showed that there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of CHD or CVD.
In this post about dairy fat, Stephan Guyenet had an apt aphorism:
"The fat is where the vitamins A, K2, E and D are. The fat is where the medium-chain triglycerides, butyric acid and omega-3 fatty acids are. The fat is where the conjugated linoleic acid is. So the next time someone admonishes you to reduce your dairy fat intake, what are you going to tell them??"
I do think pastured butter will be ways better than regular butter and that distinction should be made. But I think both will healthy for most people (though perhaps not every living person on the planet). Anyways, in addition to the study cited by Stephan (about how "People who ate the most full-fat dairy had a 69% lower risk of cardiovascular death than those who ate the least"), here are some studies I found:
Lots of people think coconut oil has cholesterol in it too - it's just people who are misinformed. When people had a lot less chronic illness, the average per capita consumption was 16 lbs/person/year, and more for people who could afford it.
The Bulletproof Diet includes Bulletproof Coffee, which is grass fed butter or ghee blended with low-toxin coffee and MCT oil. People who use it feel AWESOME and tend to lose a lot of weight if they need to.
I gave a talk at the last BIL Conference about butter, focusing on butyrate and its effects on brain inflammation, blood chemistry (cholesterol normalization), and weight loss. Pretty amazing info out there. Haven't posted the video yet but it's on the way on www.bulletproofexec.com.
Ask for evidence that butter is "destructive" - I didn't find anything convincing. It's the highest nutrition part of milk - in fact, I don't touch milk or cheese, just butter or even better, ghee, from grass fed cows. That stuff is rocket fuel.
Yes butter is safe for just about every single human being living on this planet.
It's very low in both lactose and casein. Loaded with heart healthy saturated fat. Great source of Vitamin A, Vitamin K2 and others.
When I cook with a fat, my preferred choice is butter. I'll also throw it on just about anything.
It will make liver taste ok too.
Actually Butter should be healthier than Tallow (both come from cows). It has much higher concentrations of short and medium chain fatty acids, the reason why it stays liquid at lower temperatures than Tallow. It is known that both short and medium chain fatty acids have a lot of benefits. SCFA are anti-bacterial and anti-fungal and reduce stress in the digestive system. MCFA creates Ketones, even when eating a higher carb diet. The MCFA is the reason why Coconut oil helps people so much.
Cordain has been a bad influence on Paleo diets :-(.
I don't know what to think anymore. I sure like my low carb (<100/day) diet, but I still can't imagine eating so much butter. Maybe I'm brainwashed from 40 years of high carb low fat info. Anyone else out there confused and skeptical of all studies?
NO. Saturated fats clog up your arteries. Don't believe the Paleo dogma that will try to tell you otherwise. Most of these sites are funded by meat lobbies that are trying to brainwash the public into thinking that saturated fat is good for you. Click here to read more.
