Jim Fixx:
Lessons:
- family history of heart attack and premature death
- was morbidly obese and a sedentary smoker at age 35
- was probably an out-of-control diabetic
- did not have a healthful diet
- autopsy - 3 coronary arteries almost completely blocked with plaque
- dead at age 52
Lessons:
- unstable plaque in coronary arteries causes heart attack and death
- exercise does not prevent formation of plaque
- faulty diet is primary cause for plaque formation
- exercise can stabilize plaque and reduce risk of them from breaking off
The man who wrote Winterdance, a fine book about running the Iditarod, also died from a heart attack. His story is similar to that of Fixx. Let us celebrate those who try.

Welcome, CarScar.
There are plenty of people here who initially came off wrong -appearing maybe like a troll when really they were just. little over-enthusiastic when expressing their opinions. If they were willing to listen and learn, they and everybody else benefitted..
The thread has already illustrated that there are some people here with deep knowledge of health and nutrition. Stick around and think a little before posting threads that may provoke unintentionally.

Some of the best diet related information we have comes from the blue zone studies. I don't agree that meat in general is unhealthy. I do think the source of animal protein is extremely important. I also think that most people consume too much animal protein. It is my opinion that most diet related health problems come from processed foods, including fast food. I also think too many seemingly healthy active people think they can get away with a less healthy diet because they exercise.

It’s always remarkable to me that people have such strong and unequivocal opinions on questions where the real experts are uncertain and there is no scientific consensus.

You're going to have to explain how blood pressure can determine which foods are good or bad for you. Never heard of that one before

I don't necessarily disagree that diet or exercise changes BP from day to day. But does that matter, as long as one stays under the age-appropriate numbers? I'm not obsessive enough to check my daily routine against my BP. That level of obsession would raise my BP for sure. We've been natural food "vegetarians" who also consume dairy and fish for 50 years.
Bragging about one's lack of medical care isn't a good look, IMO. Knowledge is power.
I was raised by wolves, BTW, or so says my wife. There was the time on our Alaska homestead when my brother and I, 9 and 12, left alone by our parents for the day and playing outdoors, watched a column of about 20 wolves trot across the small clearing around our house, nose to tail in a straight line, looking neither to the left nor the right, and about 20 feet from us. We held perfectly still, no problem. They were beautiful.

Red meat consumption was positively associated with blood pressure.

Eating too much sugar can inhibit the production of nitric oxide (NO) in blood vessels. Nitric oxide normally helps with vasodilation (expanding of the blood vessels). Without NO, vasoconstriction (narrowing of the blood vessels) can result, leading to high blood pressure.

Enough of this thread has been deleted that I cannot tell what exactly the controversy is. But I was a serious runner from the mid 70's through mid 80's (Jim Fixx era) and I certainly recall him. I don't recall him saying much of anything controversial other than this idea that some amount of weekly running would 'make you immume' from serious heart issues (clearly not true in his case). At least I associate that flawed concept with him, but maybe my recollection is incorrect here. But I sure don't remember much from him that I would consider controversial.

There is his video on youtube about 1 year before his death. He has red face, which is usually sign of high blood pressure. I am sure his BP was elevated for a few years before dying. He could check his BP and adjust his nutrition. Another redface was Dr. Atkins, creator of "meat and fat diet". He died of heart problem, what a brilliant doctor!!!

However he did die WITH heart disease. In his case it was cardiomyopathy. This is a weakening/thickening/stiffening/etc'ing of the heart muscle. The causes are not well understood (although genetics plays a strong role here). There is no known relationship between cardiomyopathy risk and diet.

Related to the car5car quotation in Post #36 above. I'm still wondering how you can determine which foods are healthy for you based on blood pressure readings? Any answers or any references would be appreciated. That would be a great way to start the new year off right if its plausible.

Well, there may be a certain liquid diet that can cause cardiomyopathy: heavy alcohol consumption.
The medical folks gave it a name: alcoholic cardiomyopathy. I'm pretty sure that's what killed my sister.

Thought that I had also read that Jim Fixx was also a heavy smoker before becoming a runner. As we all know, smoking exacerbates a plethora of health related issues (including the heart) which may have also contributed to his untimely demise. His legacy was to inspired an entire generation to start running and to live a healthy lifestyle - myself included. I was a runner for 12 years before beginning a slow transition to cycling.

So red meat -- to eat or not to eat, that is the question.
Here are some guidelines from the "experts":
Here are some guidelines from the "experts":
World Cancer Research Fund International
Limit red and processed meat
If you eat red meat, limit consumption to no more than about three portions per week. Three portions is equivalent to about 350–500g (about 12–18oz) cooked weight. Consume very little, if any, processed meat....Meat can be a valuable source of nutrients, in particular protein, iron, zinc and vitamin B12. However, eating meat is not an essential part of a healthy diet. People who choose to eat meat-free diets can obtain adequate amounts of these nutrients through careful food selection.American Institute for Cancer Research
Limit Consumption of Red and Processed Meat
You don’t have to eat red meat to get the nutrients you need, but eating moderate amounts provides a good source of protein, iron, zinc, and vitamin B12. However, eating more than 18 oz. of red meat weekly can increase your cancer risk. If you eat red meat, limit the consumption to no more than 3 portions a week or about 12-18 ounces (cooked). Eat little, if any, processed meat.

As far as processed meats, I believe the WHO classifies processed meats the same as plutonium in carcinogenic properties.
