Actually we were never meant to be either sedentary nor living on the foods which only came into the human diet in substantial amounts with agriculture around 8000 to 10,000 years ago - PS adding this 3 minute video clip again as very appropriate here: https://www.youtube.com/watch?v=v8WA...931CCD7E648328

If we were never meant to eat the foods that came into the diet in the last 10,000 years, why are we meant to eat foods that came into our diet in the last 2 million? Humans/hominids have been evolving for 25 million years and 90% of that history our ancestors ate almost exclusively a plant based diet. Here's a brief video outlining this point: http://nutritionfacts.org/video/the-problem-with-the-paleo-diet-argument/
"You can feed a dog 500 eggs worth of cholesterol ... and they just wag their tails; their bodies, evolved from wolves, are used to getting, eating, and getting rid of excess cholesterol, whereas within months a fraction of that can start clogging the arteries of animals adapted to eating a more plant based diet."

But when it comes to China, 'The China Study vs the China study' - although lengthy, it’s worth reading this, every word, all the way through to the end: https://proteinpower.com/drmike/2010...e-china-study/
https://proteinpower.com/drmike/2010/07/27/the-china-study-vs-the-china-study/I really don't get the argument where he assumes that people will assume that the author is talking about human studies when he indicates the author describes the study as based on rats. Way too many assumptions. Re. observational studies, that was what was used to tie cigarettes to lung cancer, and it also took a long time to be accepted by most, at the cost of many lives. Double blind randomized controlled studies don't fit all circumstances so sometimes we have to make use of observational studies. That they are not the ideal type of study does not discredit them, nor does the fact that the China study is not perfect ... and it's not like it is the only study supporting the benefits of a plant based diet.

Here is an interesting Ted Talk where an Archeologist discusses the Paleo diet: https://www.youtube.com/watch?v=BMOjVYgYaG8. The speaker addresses three myths: 1. Humans evolved to eat meat and paleolithic people consumed it in large quantities, 2. Paleolithic people did not eat whole grains or legumes, 3. Paleodiet foods are what our Paleolithic ancestors ate; and suggests 3 lessons learned: 1. There is no one correct diet but diversity in our diet is key, 2. We evolved to eat fresh foods when they are ripe, 3. We evolved to eat natural whole foods in their complete package.
 
Everyone has to eat what is best for them. I know from personal experience that people don't like to change what they eat if it means giving up certain foods*. I've changed my ‘way of eating' a few times over my life - at one point I was really into the complex carbs/low fat thing, made all my own bread, as wholewheat wasn't much available then, ate brown rice, ate only low fat foods and mostly vegetarian, the whole complex carb/low fat kaboodle that began during the early 1970's. I found after about 30 years of that way of eating that it wasn't good for my health and had to make major adjustments. Hence my writing about the paleo way I eat now - I appreciate that it is quite radical. I never think anyone should radically change the way they eat unless they have done a lot of research and checked their health to make sure it is right for them.

*PS for example, my DH, who does not eat paleo, is so annoyed that he put on wieght over the past few months and Christmas. He knows that prior to this that when he gave up fruit, such as bananas and pears, that he lost a bit of weight, and now he knows that he has to cut back on bread and rice cakes which he loves. He hates it. I don't tell him what to do, he just knows what foods make him gain weight easily, and he knows the reasons why, but that doesn't make it any the easier for him to cut back or give them up and he gets pretty miserable about it.

The reason people put on weight with a high carb diet is that you need a higher caloric intake of carbs to feel satiated compared to protein. There are vegetable sources of protein that do the same thing. If you read the Bible you'll notice they bang on about bread a lot. They lived on the stuff and women baked it every morning. But it wasn't the refined crap we eat today. The Romans were a greater threat than coronary artery disease. There's a difference between eating carbs and gorging on them.

I'm essentially vegan, except for fish and fish oil. I eat nuts and don't refrain from healthy fats. Even Ornish/Esselstyn are lightening up on nuts. I mean seriously, no meat, oil or nuts. That's two out of three macronutrients out.

btw your desire to eat animal flesh dissipates after about two months, so I seriously don't feel like I'm missing out. However, you need a source of B vitamins and Iron. I supplement my diet by eating half a bicycle twice a day.

My wife says the same , go a couple months without and my desire will go away...But seriously you no longer desire steak, a burger or ribs?

I don't miss them at all. I can't remember the last time I had any of these, probably once or twice within the last year and not by choice but because others chose the restaurant or the menu. I think the key is finding and getting used to tasty alternatives. I had Chinese today and the vegetarian dish they make is very bland, so I ask for it with a spicy sauce that they use on some other dishes and it is so much better that way. I would have a harder time going without pizza, so I don't. I eat it maybe once a month. Frankly I don't understand why vegetarian or vegan has to be all or nothing. It's not what you eat occasionally that is going to be harmful (or helpful) to your health in the long run, but what you do regularly. Perhaps it is different if someone is trying to reverse heart disease, but I am trying to prevent it. I just try to increase the healthy things that I eat and reduce the things that I view as harmful. One way I do this is by drinking green smoothies, about 1/3 fruit and 2/3 greens. I generally drink two of these a day which is roughly 8 servings of fruits and vegetables. I also switched from beer and scotch to red wine (most of the time). I don't feel like I'm missing out on anything.

?? How does one eat a bicycle?

I grind it down and then consume the iron filings, mixed in with my oats and soy milk. Some sliced banana on top.
I don't actually eat the whole bike. I avoid the tyres and plastic bits.
 
My oldest uncle found out quite unexpectedly that he had major coronary blockages in his sixties, to the point where he needed immediate triple bypass surgery.

He changed almost nothing about his diet or habits afterwards. He told me that the doctors told him to drink less alcohol after the operation, so now he only drinks five beers a day instead of an entire six pack.

His CABG was well over 15 years ago. He is 79 now -- 80 in less than six months. Some people do all the wrong things and they are fine -- others step out of line one centimeter, and POW! "Justice" is served.

Anyhow, these discussions on diet sometimes start to remind me of religious arguments. Probably not a coincidence. Not saying who is right or who is wrong, just... There is a lot of ideology.

And it's hard for there NOT to be when, let's face it, the average American eats the standard American diet and lives to their late 70s or early 80s. If you really have to worry about your diet to live that long, you lost.
