Large-Scale Dietary Study: Fats Good, Carbs Bad (cbsnews.com)
An anonymous reader quotes CBS:
New research suggests that it's not the fat in your diet that's raising your risk of premature death, it's too many carbohydrates -- especially the refined, processed kinds of carbs -- that may be the real killer... People with a high fat intake -- about 35 percent of their daily diet -- had a 23 percent lower risk of early death and 18 percent lower risk of stroke compared to people who ate less fat, said lead author Mahshid Dehghan. She's an investigator with the Population Health Research Institute at McMaster University in Ontario... At the same time, high-carb diets -- containing an average 77 percent carbohydrates -- were associated with a 28 percent increased risk of death versus low-carb diets, Dehghan said...
For this study, Dehghan and her colleagues tracked the diet and health of more than 135,000 people, aged 35 to 70, from 18 countries around the world, to gain a global perspective on the health effects of diet. Participants provided detailed information on their social and economic status, lifestyle, medical history and current health. They also completed a questionnaire on their regular diet, which researchers used to calculate their average daily calories from fats, carbohydrates and proteins. The research team then tracked the participants' health for about seven years on average, with follow-up visits at least every three years.

Not just fats less bad - fats good (up to a point). The study found that your risk of early death goes down the more fat you eat, right up to 2.5 times the current recommended fat intake.
Oh, quit with the "poison" nonsense. Sugar is our primary cellular fuel.
Sugar is not our primary fuel. Glucose is our primary fuel. Sugar is 50% glucose and 50% fructose. High fructose corn syrup can be as high as 80% fructose. Fructose is not the same as glucose. Fructose is processed by the liver the same way as alcohol and other poisons. The only difference between fructose and alcohol is that fructose doesn't cause you to get drunk. Very few people would dream of giving their 8 year old multiple glasses of alcohol a day but millions of people give their 8 year olds multiple glasses of HFCS every day.
Oh, quit with the "poison" nonsense. Sugar is our primary cellular fuel. The issue is the quantity, the level of refinement, and the relative difficulty in obtaining food not saturated in it.
That turns out not to be the case. It is well known, and has repeatedly been demonstrated, that the body's cells run equally well on fat. See, for example, https://www.ncbi.nlm.nih.gov/p... For further copious details, including case studies, see Gary Taubes' excellent summary "Good Calories, Bad Calories" (published in the UK as "The Diet Dilemma" for reasons unknown to all but the publisher).
The only cells that appear to need glucose are those of the brain. However, it is easy to get the wrong idea even here. After a few days' fasting, the brain starts to use ketones which are produced as a by-product of metabolozing fat for fuel. A rather small minimum amount of glucose still seems necessary, but the liver manufactures this through gluconeogenesis. Indeed, the paper cited above clearly implies that the body can manufacture everything it needs for full health in the absence of any food intake at all, provided fat reserves are adequate. If the only source of protein were the body's own muscles, etc., no fast could possibly extend longer than a few months at most.
The only reason why we have all been told that glucose is the body's normal fuel source is that we live in a grain- and sugar-fed society. Hunter-gatherers obtain much less glucose and regularly fast for varying periods. As long as one does not eat carbohydrates, fasting does not cause hunger. For instance, as I write this I have eaten no solid food (only some coffee with cream and soup) for over 40 hours. I feel great, and have absolutely no desire for food.
I am sure that there are many other solipsists out there.
> Well, the longest lived communities in the world have one thing in common. They DO eat very little meat and fish
Completely untrue.
It's very true! Sardinia, Okinawa, and Icaria in Greece are the three places with the longest life spans. All three locations have a legume based diet and traditionally eat almost no meat other than occasional fish. Importantly, they also don't eat any refined grains either.

There's also lots of money involved with selling a couple of cents worth of corn or grain + chemicals in a box for several dollars with a long shelf life. Meats, cheese, eggs and produce not so much. What do you think is the most likely explanation?

Actually this is not quite true. The fructose from high fructose corn syrup does get processed in the liver but that is due to the concentration levels. The fructose from fruit is not normally processed that way. when you eat fruit it takes time for your body to break it down and get to the sugars in it. This causes the amount in your bloodstream to be lower at any given time and a different chemical pathway is used. When you have purified sugars your blood sugar level spikes to dangerous levels and while cells can rapidly pull glucose out of your blood they can't handle all the fructose and so your liver gets handed the job.
Also just to be pure 100% fruit juice is JUST AS BAD as soda in terms of the sugars. It makes the sugars extremely available to your body and causes your blood sugar levels to spike. It is far better to eat the fruit than to drink the fruit and this includes smoothies. In general you want to avoid drinking your calories.

Too much water is poisonous too. Until very recently, fruit(even whole grains quickly spoil) was available to us only during very limited times of the year. From a survival perspective it makes complete sense for our body to turn episodic food sources directly into fat.
Eating 6 or so oranges sounds kind of gross and gluttonous but that's exactly what you are doing when you drink a restaurant sized glass of orange juice, and the majority of people in the USA don't think twice about this.

You two are talking past each other. Sucrose, glucose, and fructose are all sugars.
Alle Dinge sind Gift, und nichts ist ohne Gift, allein die Dosis macht dass ein Ding kein Gift ist.
All things are poison, and nothing is without poison, the dosage alone makes it so a thing is not a poison.

Not really. Sucrose is cleaved by sucrase in the small intestine almost immediately upon ingestion, like within 5 minutes.
Studies show no difference in the absorption rate of sucrose vs. HFCS.
I can tell you from direct experience that eating high-carb caused by A1C to skyrocket and my my liver enzymes and cholesterol levels to go off the chart... Then the gradual but sure weight gain. Switched to "ketogenic" and intake is mostly fat, with moderate protein, and carbs 20g on a daily average and I've went from 270 lbs (42in waist) to just under 210 lbs (38in waist), my A1C reads "ideal" instead of diabetic, and I don't have issues with high and low blood sugar episodes and don't feel like I'm going to feint from long periods of not eating. And my Dr doesn't look like he's about to fall out when reading my cholesterol level test. My joints also hurt less. This is over 9 months. Note, when it comes to "low-carb" foods sold in the store, the manufacturers have taken to making them high-protein, with a reduction in fat, which, when you get too much protein (or in the case of Atkins, putting pasta in them!), I understand that your body turns excess protein into sugar when not needed, so too much protein can also contribute, though not as badly, to the general carbohydrate overdose that is deployed in our generally available food stuffs.

Glucose (dextrose) is roughly half as sweet as fructose. People use HFCS because it's sweeter than normal syrup.
Sorry, but not really true.
The "Mediterranean people don't eat meat" thing started when an American researcher decided to prove vegetarianism is better for you than eating meat. So he went there to do a health study, since they were known at the time to have long, healthy lives.
He chose to do his study during Lent. Which, especially at the time, meant the Catholics (almost all of the study subjects) were "giving up meat for Lent."
So that study was bogus, and he KNEW it. ...and, by the way, he later went on to be very influential in Washington, and was behind the whole movement that later pushed the Food Pyramid and other bad ideas.
On a similar note, the actual Okinawan diet (that people live a long time on) is very meat-heavy, and the trendy "Okinawan diet" doesn't have much to do with it other than the way they cook things. The actual Okinawan diet "starts with pig and ends with pig."
