Reply to comment by RedditUserNo1990 in Fracture Risk in Vegetarians and Vegans: the Role of Diet and Metabolic Factors - PubMed by RedditUserNo1990

Great study. It has none of those funny little oversights that the vegan lobby neglected when they drew a line of correlation between diary intake and hip fractures a while back.

The oversight being that they had compared rates of hip fractures in Scandinavia to that of China and concluded that "since hip fractures are more prevalent in Scandinavia and Scandinavians consumes more dairy...". Anyone reading this will of course realize that large parts of Scandinavia is covered in slippery ice half of the year, greatly contributing to the rate of hip fractures...

Reply to comment by traketaker in A systematic review and meta-analysis has concluded that increased consumption of dietary carbohydrate intake is associated with increased risk of cardiovascular disease, stroke, and all-cause mortality. by Meatrition

It’s made of carbon and hydrogen. It’s a carbohydrate. There are three main types of carbohydrates:

Sugars. They are also called simple carbohydrates because they are in the most basic form.

Starches. They are complex carbohydrates, which are made of lots of simple sugars strung together.

Fiber. It is also a complex carbohydrate.

I was making the point because the above poster was trying to argue that candy and brown rice are equally bad be abuse they are “carbs.” All carbs aren’t created equal. Brown rice has fiber and other important nutrients and overall drastically different physiological effects than pure simple sugar.

In South Korea, universal healthcare was framed as fighting communism by being better than North Korea.

Other way around. We already had the words "acceleration" and "speed". Newton came up with Calculus to put those words into math.

>So with the topic of particle entanglement and why it can't be used for faster than light coms, I would work backwards starting from an analogy such as - there are two boxes that each contain a blue marble, opening either box changes the color of both marbles to green - a term or phrase could then be made to represent that particular flow of information.

Your description isn't accurate in the least, and that's the problem. "Changing color" is already introducing wrong ideas. Nothing is "changing".

You can't even convey the significance of entanglement without first going over wavefunctions and eigenstates.

That's usually the worst approach. The evidence is in the study for this post. People have cognitive dissonance and will do all sorts of menatl gymnastics when you take that approach.

Mostly my assumption comes from taking a look at how the language of math has evolved over the years. For example, first and second derivatives are easily understood and we use them to speak about rate of change and acceleration. Without the derivative and the concepts behind it, it would be hard to talk about acceleration without using the math. So with the topic of particle entanglement and why it can't be used for faster than light coms, I would work backwards starting from an analogy such as - there are two boxes that each contain a blue marble, opening either box changes the color of both marbles to green - a term or phrase could then be made to represent that particular flow of information.

Reply to 15 million people live in possible flood path for melting glaciers | Glacial lakes can cause flooding if an ice or rock dam holding back the water fails, an analysis has found by chrisdh79

From the article: As many as 15 million people live in areas that could be flooded by a natural dam failing at a glacial lake, according to the first global analysis of the hazard.

Tom Robinson at the University of Canterbury in New Zealand and his colleagues identified glacial lakes in satellite imagery. They then determined the number of people living within 50 kilometres of each lake, and within 1 kilometre of the river where water would flow in the event of a glacial lake outburst flood (GLOF). These floods can happen when an ice or rock dam holding back a glacial lake fails, or a rock slide sends water sloshing over a natural dam.

The researchers found up to 15 million people could be affected, with 9 million in the Himalayas, 2.5 million in the Andes and 2.2 million in the Alps. More than half of the 15 million live in either India, Pakistan, Peru or China.

Outburst floods are unlikely at many glacial lakes, and the study presents a simplified view of the areas any flooding would affect, says Simon Allen at the University of Zurich in Switzerland, but he says the global view helps draw attention to vulnerable and understudied regions.

I mean if he was eating red meat, store bought fruit, and store bought potatoes he could easily have had a lack of b vitamins and a lack of calcium, even while eating chocolate. which would have resulted in arterial build up and a heart attack.

Most fiber is insoluble. It just acts to carry everything through your system and clean you out. There are dietary fibers that do break down and are carbohydrates but that's a small amount. So it's a bad idea to just lump fiber as a carb.

"Dietary fiber is the kind you eat. It's a type of carbohydrate."

"Your body cannot digest fiber, so it passes through your intestines without being absorbed much"
