Another newspaper headline about what we should eat. But this one is different.

The story (Kosten kan påverka prostatacancer), is about prostate cancer. As usual is it not hard to find any English articles a: Men With Prostate Cancer Should Eat Healthy Vegetable Fats 

Unfortunately does the paper not exist as full text version and only as an abstract. But it gives some information.

So what is it about and why do I mention it? Because it mostly support what I have now understood for a year. Removing carbohydrates from your diet and increase the fat intake could decrease the risk for cancer. Mind you, I using the word could.

Reading it did I feel a little split. I felt that I was cherry picking parts of it. Increase fat, and decrease carbs. I am all for it. But then does the observational study find that saturated fat is bad. Guess what, I do not agree. But the big problem, it is only a observational study no more. As one commentary was:

Using data from food frequency questionnaires completed every four years during follow-up, they found that men who consumed more vegetable fat had a lower risk of prostate cancer death.”
”Thus, in the absence of randomized trial data, it is impossible to use these data as ‘proof’ that vegetable intake lowers prostate cancer risk, and the authors have carefully avoided such statements,” Freedland continues.
”When counseling patients, I remind them that obesity is the only known modifiable risk factor linked with prostate cancer mortality to date. Thus, avoiding obesity is essential. Exactly how this should be done remains unclear, although the data by Richman et al suggest that substituting healthy foods (i.e. vegetable fats) for unhealthy foods (i.e. carbohydrates) may have a benefit. Determining whether this benefit is due to reduced consumption of carbohydrates or greater intake of vegetables will require future prospective randomized trials,”
But even though I can be accused for cherry picking, do I take this as another small piece of the puzzle on what is healthy food. Less carbohydrates, and more fat, and yes even saturated.

The reason besides the feeling of bias in the articles I found, animal fat is unhealthy and vegetable oil are good, are the questioners.  It took me some time to find them. But they are here. They ask people every 4th year about what they eat. Since 1986, so they are persistent.

Have in earlier post, pointed out how strange it is to believe you will get the truth out of these. People lies, most of all to themselves. Especially if they believe certain foods are bad for you health and they are health conscious. People over or underestimate all the time. Most you can hope for is that over time they will do it consistently. As long they do not change opinion about what one should, or not should eat. But the hope that people as a group will lie consistently is futile. Because each one tries to hide different things depending on how they try to eat and live otherwise.

So what does the questioners say that makes me think that their assessment (because that is all what it is) of what the subjects rely is eating and in this specific case, in regards to how much animal fat they get. Or rather in combination with what. Screws up the data.
Take a look on one part of it.
Questionair for harvad study

So if you eat sausages that contains all kind of preservatives, hamburgers with sweet bread, sandwiches or pasta together with meat of different kinds then you eating animal fat. I.e. saturated fat. And if you then get an health problem, it is blamed on saturated fat.

This problem that we always mix our diet with combination with different food items, will screw up things. Especially in questioners like these that enhance the problem.

And this kind of data is precisely what each and every news paper headline that warn or advice us what to eat, is built of.

I remember studying economic for a semester. They taught us how to make predictions, or outcome of different scenarios. And the teacher then said. You will go out in the world and use these methods. They will be presented to the executives, who will say “now we finally have numbers, and can make decision on what to do”. All the while, you know how these numbers was created.

In short shit in, shit out.
