"The Tsimane get 72% of their energy from carbohydrates. The fact that they have the best indicators of cardiovascular health ever reported is the exact opposite to many recent suggestions that carbohydrates are unhealthy." Refined carbs ARE unhealthy and it's a bit disheartening that they didn't make that distinction in the article.

In common UK parlance carbohydrates don't include sugars although chemically speaking they should. I think metabolically speaking there is a useful distinction to be made, in fact people are making it here. In dietary context schools have categorised potatoes, rice, pasta, even bread as sources of "carbohydrates" and sweets as sugar sources.

What is the difference?

They have different impact on blood glucose and insulin

According the the following, sucrose has a glycemic index of 65. Plantain has 55. Brown rice has 68. Does the glycemic index say anything about impact on blood glucose and insulin levels?

But is their health abnormal after accounting for the usual RRs associated with their BMI, exercise, fiber and trans fat intake? They don't drink or smoke, I presume?

The difficulty with "non-mathematical" sciences is that they tend to treat math as a tool for validation rather than expression. This is partially a failure of communication on the part of mathematicians.

One thing I didn't get a clear answer from the doctor about last time I saw one was this. Can you unclog your arteries by changing your lifestyle, ie diet and exercise, or is the clogging permanent?

Diet can unclog arteries, at least in some cases.

Well this article seems to be pushing for more carbohydrate consumption and putting that increased level of calories from carbs at the same significance as the massively increased level of physical activity they have.

The fact that they walk a huge amount (16,000/17,000 steps per day) seems to be a very obvious factor. Unfortunately, getting this kind of behavior, at least in the US, would be enormously challenging, because our land use policies and regulations are generally designed to make walking useless and/or painful. I've lived in several parts of the US, currently live in Munich, only NYC felt close to Munich in walkability…

Are you unable to walk around your neighborhood in SV, Seattle and other places? I live on Long Island (not NYC) but it's not hard to find places to walk around in safety. I put in 3-5 miles (roughly 6,000 - 10,000 steps going by Google) a day just aimlessly walking side streets for general exercise and clearing my mind. When I visited SV it didn't seem too bad downtown. Can't speak for the other places though. But i…

Even in cities like SF and Seattle where it can be dense (in the city proper) it's still not quite dense enough with good enough transit systems to promote walking to 100% of your destinations. You usually have to Lyft/Uber most of the way still.

Yes, I would be interested in how I, an in-shape individual who exercises regularly compares to the Tsimane.

I was also surprised that the OP scoffed at the 30%. If you sold a drug that did that you would be an instant billionaire.

This is true, but it goes so far beyond that. Lack of mixed use zoning is also a big factor, as are little details like speed limits, road widths, pedestrian islands, cut throughs, plazas, walk/bike paths, size and placement of crosswalks, placement of traffic signals, etc.

Something as small as the curve of the corner of the sidewalk at the intersection, most people will never think about, but it absolutely impacts walkability (the larger and less 'sharp' the curve, the less walkable it is).

To add to your point Okinawans once had the greatest life expectancy on Earth and the majority of their diet was carbs too. Since the introduction of “western diet” post WW2 the majority of their diet is still carbs and yet they now show significant increase of Chronic disease (obesity, heart disease, type 2 diabetes, fatty liver disease and kidney disease) and lowered life expectancy.

What is that disease attributed to? Do you know?

Doesn't even mention sugar. Seems like that would be a very large and important difference. Just says "72% of calories come from carbohydrates compared with 52% in the US", which might encourage a westerner to eat more carbs, but if they're eating whole rice and we're eating sugar that seems kinda important. Comparison of gut bacteria would be interesting too, bet that's as important as the diet itself.

They're also exercising more than 100% of what Americans do.
