  • it's interesting when we design our studies we provide diets that are high

  • in starch and then we take away that starch and replaced it with sugar why do

  • we even see such unfavorable effects when we replace pasta or bread with a fructose sweetened beverage

  • or let's even say high fructose corn syrup sweetened

  • beverage well to answer that question we're gonna start first with the glucose

  • the grains that we eat and we call carbs are pretty much pure glucose and it goes

  • into our bloodstream slowly cause it takes a while for those enzymes in the

  • intestine to break it all down the glucose leads the intestine in what we

  • call the portal vein and that veins first stop is the liver if the liver

  • needs energy that liver is going to pull the glucose in if the liver has enough

  • energy most of the glucose bypasses the liver and is delivered to the rest

  • of the body it gets to be used by any other place in the body that needs

  • glucose now with fructose its different we're talking about fructose in the fructose

  • sweetened beverages are subjects consumed but we're also talking about

  • the fructose in sodas because high fructose corn syrup contains fructose

  • so fructose is in the intestine and it too is delivered directly to the liver however

  • there's an enzyme there that's always turned on so it takes any fructose it

  • can get its hands on even if the liver has enough energy

  • very little fructose gets delivered to the rest of the body so what we end up

  • is this fructose overload in the liver it needs to start storing it as fat when

  • you increase your levels of liver fat you're gonna have more fat heading out

  • into the blood with more fat heading out in the blood

  • you end up with higher levels of triglycerides and cholesterol both of them

  • risk factors for cardiovascular disease there's another problem we believe liver

  • fat decreases insulin's ability to do its job thats increases your risk of

  • diabetes

  • there's another problem when your insulin isn't working well it also

  • causes more fructose to be turned into fat and it is also going to

  • increase the amount of fat that liver sends into the blood there's another

  • problem this group that consumed fructose tended to gain that weight within

  • the abdominal cavity this is what we call visceral fat that makes us apple

  • shaped

  • so what we have is this vicious cycle going on that's really why

  • metabolic syndrome tends to be a group of problems they make this little

  • vicious cycle where one makes the other worse and they just go around in this

  • circle what we all need to do is get to the point where sugar is a special

  • occasion food it's not a staple and that's where we need to think about our

  • foods and what they can be doing to our health are you wondering how much sugar

  • you're eating click on this video to find out and be sure to subscribe to figure 1
