An Extended Interview With Ray Peat

Here is a long interview with biologist, Dr. Ray Peat.  Of course he is supportive of REDUCING PUFAs and enjoying your fructose.

Listen here.

Misleading PUFA Studies

Imagine you are a fat person.  In the past you would try to drop some weight by eating salads and drinking diet soda.  What you would be doing is INCREASING your PUFA intake with salad dressing but DECREASING your fructose intake with diet soda.  This could be expected to show some mild improvements in your health metrics if you are part of a clinical study.  But these clinical studies don't test for the combination of PUFAs and fructose.  They are usually just isolating their PUFA intake.  The measurements are almost never given in the context of fructose intake.

When you see a dietary study that shows an improvement with increased PUFA consumption, make sure they are taking measures of participants who are not decreasing their fructose intake.  How much better would the study participants do with a low PUFA diet?  Hopefully, some day, we will know.

The PUFAs and Fructose Reaction

I try to imagine it like this:

If you put a lit match up to a little puddle of gasoline, the gasoline will start on fire.  It is a common reaction that most people are familiar with.  Now imagine you have a huge puddle of gasoline that is sitting out on a hot day.  If you get anywhere near that gasoline with a lit match, it will have a much more violent or explosive reaction. 

Now imagine the little puddle of gasoline again but this time someone comes up to it with a flame thrower!  The little puddle will burn just like it did before.  The size of the fire doesn't make much difference in how the gasoline will react.  Same for the huge puddle of gasoline.

I imagine PUFAs to be like the gasoline and fructose to be like the fire.  A person could theoretically eat lots of fructose and if they only get a little bit of PUFAs, it won't make much of a difference.  However, if a person is consuming a lot of PUFAs then there is going to be a strong reaction to fructose in some people.  But it is not the fructose that is the bad guy.  It is the careless consumption of PUFAs in people who have a strong reaction.

PUFAs = BAD----Fructose = GOOD!

There has been such a vehement effort to attack HFCS and sugar and fructose that conspiracy theorists would have a heyday with my support of fructose.  Surely I must be a shill for the corn refiners.  One could almost buy that except I theorize that high PUFA oils (you know, like corn oil) are extremely bad products to put into food.  So I am canonizing and demonizing foods from the same source; corn. 

Actually, I don't think either one is truly bad.  They are both just food.  But the reaction of the two in some people is unmistakable.  If I had to pick which one to minimize in my diet, I would choose PUFAs. 

So don't throw gasoline all over your metabolism!  Keep your puddle small and enjoy the fire :)

The evidence is starting to mount against PUFAs and fructose. I am expecting to see a very big exodus from the use of PUFAs.  I can't imagine it is going to take too long in the day and age of the internet.

But what would a world without obesity look like?  I imagine it would be extremely competitive for those looking for dates.  There would be a HUGE reduction in healthcare costs.  Incredibly, lifespan would lengthen even further.  This may lead to a bit of a population boom.  Diet gurus would disappear (yeah!). 

I'm thinking that competition overall would be greater, not just in dating.  There would be a greater need to distinguish one's self in a highly competitive environment.  Once fat Betty and fat Bobby don't look so different, they might just kick some ass in business, entertainment, sports, and elsewhere in the world.

What about the price of coconut oil?  OMG!  Through the roof.

Do you have a prediction for when obesity disappears?  Leave a comment.

Who consumes the most PUFAs?

Q.  What country is the greatest per capita consumer of PUFAs?

A.  Israel

Here is a PubMed paper on the "Israeli Paradox".

Two key ingredients point to the cause of obesity.

The PUFAs and fructose theory IS THE ONLY DIETARY THEORY that explains why the low carb/high fat eating Inuit stayed lean AND why the high carb/low fat eating Kitavans stayed lean AND why the obesity epidemic in the U.S. is increasing with its PUFA consumption AND why the French paradox is effective AND why the Okinawans stay lean (and may help explain why they live so long) AND why a person can still get fat eating only "healthy" vegetarian foods.

How I Decided Obesity Is Caused By PUFAs And Fructose

It all started with a NY Times article on obese monkeys.

Here is the question:

How did they make the monkeys obese?

It turns out that it was not complicated at all.  They simply add some foods with two primary ingredients that have already been under suspicion.  But when they combined them both, some fat magic happened.

Keep in mind that these are monkeys in cages.  There are no "self-esteem" issues at play.  It had nothing to do with "eating too much and not exercising enough".  They did not select "couch potato" monkeys.  They tried to induce the "couch potato" lifestyle on the monkeys, but it was the diet that tipped the monkeys into obesity. 

All the monkeys were getting monkey chow which was about one third fat, (probably) 20% protein, and about 50% carbohydrates.  That is the standard monkey chow every monkey gets and it does not usually cause obesity.

So how do they get these darn monkeys to be fat?  They ADDED a peanut butter snack, a high fructose sweetened beverage, and occasional peanuts and popcorn.  There are two factors that stand out about those dietary additions.  Can you guess what they are?  (Hint--see title of this blog).

The fats we get in our diet basically consist of three types:

Saturated
Polyunsaturated
Monounsaturated

Saturated fats are the stiff fats at room temperature and usually have a long shelf life.  Common saturated fats would be lard, tallow, coconut oil, and palm oil.  They are usually found in our diet from meat, dairy, chocolate, and coconuts.

Polyunsaturated fats are liquid at room temperature and even when refrigerated.  They do not last long before going bad.  They are usually kept stable and safe by adding preservatives or antioxidants.  PUFAs are highest in seed oils like soybean, canola, corn, peanut, sunflower, safflower, cottonseed, grapeseed, and walnut oils.  They are usually found in our diet from snack chips (or crisps in the U.K.), salad dressings and mayonnaise, crackers, cakes, cookies, popcorn, peanuts, corn, nuts, seeds, and whole grains.

Monounsaturated fats are also liquid at room temperature but can be solid if refrigerated.  Common sources of high monounsaturated fats would be olive oil, macadamia nut oil, and high oleic sunflower (not to be confused with regular sunflower) oil.  Common dietary sources of MUFAs would be macadamia nuts, maybe some Italian or Mediterannean foods, and some salad dressings.

So did the researchers add a high saturated fat snack to the monkeys' diet?  No.
Did the researchers add a high MUFA snack to the monkeys' diet?  No.

The researchers added a high PUFA snack to the monkeys diet.  Did it work?  Not well enough.  Not until they added a high fructose sweetened drink did the researchers get the big fat monkeys.  But fructose is not effective enough on its own to cause obesity.  It takes BOTH.

PUFAs and Fructose

But how do we know it wasn't glucose (the other carb in the equation).  Because the peanuts and popcorn already have carbohydrates that break down to glucose in them.  But fructose is a different type of carbohydrate entirely.  With fructose they had the key carbohydrate that worked with the key fatty acid and did a number on their systems to generate obesity.

PUFAs and fructose is a magical blend that may be the greatest discovery in this decade.  With PUFAs and fructose you also may be able to generate diabetes, heart disease, and cancer!  Four morbidities for the price of a little vegetable oil and sugar!

Time will tell.
