Do you have any long term research?

Is this sustainable? What are the long term effects of eating the way you do?

I get this question a lot when people ask about the way I eat.  I eat a higher fat, moderate protein and lower carb diet with my primary fuel source being the fat I eat and fat that is stored on my body.  My fitness and health have never been better.  My recovery thanks to the anti-inflammatory nature of this way of eating is a breeze.   As of late,  I've been venturing into a more primal way of eating.  This basically means expanding upon the massive amount of vegetables that I already consume.

So the TL, DR version from above, I eat some meat, a lot of above ground veggies, healthy fats like coconut oil and ghee, some fruit and very minimal processed meats/cheeses/full fat dairy.

Even more TL, DR.  My diet contains almost entirely real food that grows in nature in the most natural way possible today.

It's essentially what humans have eaten for tens of thousands of years.  But didn't they die young?  Yes, around 33 was the hypothesized average life span.  Complications from childbirth, predators, and infections from flesh wounds were probably the common culprits.   It most likely wasn't from heart disease, cancer, or diabetes.   It also wasn't out of the ordinary for many to live full, healthy lives up into their 60's and 70's, some as old as 94.

Heart disease deaths

My question back usually is, have you looked at the long term effects of what you are eating?  Did you know 71% of the items at a grocery store didn't exist 100 years ago?  While I don't want to make any brash claims here, but take a look at graphs like these.  The two leading causes of death in America are heart disease and cancer.   Look at the graph for Soybean oil and start reading your ingredients list.  Soybean oil is in nearly everything.   But I'm not going to completely throw soybeans under the bus for all people,  and I'm not going to say correlation equals causation.  But the massive increase in the rate of consumption is very problematic.   Consuming to many omega 6 fatty acids leads to inflammation,  one of the primary drivers of heart disease.  For more reading on the harmful effects of soybean oil, here's a start. 

Next, there is a tremendous amount of new research coming out about the role of sugar in cancer cell growth.  Cancer cells fuel of off the sugar in your blood.  Just like every other cell in your body.  However, there is another fuel source, ketones.  Ketones are made from the breakdown of fat.  Cancer cells cannot use ketones for fuel.  So they struggle to survive.  There is a great evidence based article about that here.  

All that to say.  I'll take my chances eating real food similar to the way humans have eaten for the vast majority of human history.  I've found most people don't ever stop and think about the long term effects of what their diet currently consists of.  But they ask with skepticism about mine as they are drinking soda or juice and eating twinkies or "health" bars loaded with soybean oil.
