Why sugar is worse than fat

Watch "Fareed Zakaria GPS," Sundays at 10 a.m. and 1 p.m. ET on CNN

Fareed speaks with CNN Chief Medical Correspondent Sanjay Gupta about recent research on the risks of high sugar consumption. Watch the video for the full interview.

For 20 years, people have been assuming that fat was the enemy because it produced cholesterol, which was blocking arteries. That's not quite right.

I could talk about this all day long, because I think it highlights some very important things in terms of how we sometimes misinterpret science, or at least exaggerate it.

It was in the late '70s – in fact, there was a Senate commission, Senator McGovern, who actually looked at this issue and found that people who had very high levels of cholesterol tended to die early of heart disease. And there was also other studies that showed if you ate a diet high in fat, it raised your cholesterol. But those were two different studies. And they got really, really linked, not only by the Senate, but also in the scientific community and then by everybody else.

And what happened over the last 30 years, it got codified. It became the way that we eat low fat in this country. And nothing changed. In fact, things got worse. Cardiovascular disease remains the biggest killer of men and women. Diabetes rates are higher than ever before. Childhood obesity. So it didn't work. And I think that's what sort of prompted all this analysis.

I think there's two issues here. One is that fat doesn't get a free pass here. There's still some problems with it. It still raises cholesterol levels. That is associated with heart disease. The problem is that what we replaced fat with was sugar. And sugar may be more problematic, in some ways, for someone who's worried about heart disease than fat.

More from CNN: Our fear of fat is melting

If I put a double cheeseburger here and a big sugary drink and I asked anybody, which of these two things is worse for your heart, even a child would probably say the cheeseburger. And almost always they would be wrong. It's the sugary drink that gets converted into that bad cholesterol in our body.

But as you said, the crucial thing to understand is, it's not that fat is good for you, it's that if you replace fat with sugar, it's worse for you?

That's right.

Why is sugar so bad? Is there a simple way to explain that scientifically?

Here's a simple way – it’s that humans weren't designed to eat this much sugar. We used to get sugar once a year when fruit fell from the trees. Even honey was protected by the bees. How much food could you really eat? I mean you can't…10 oranges, that's enough. Now, we eat 140 pounds, roughly, a year, on average. Our bodies simply didn’t evolve to be able to handle that.

So it hits the liver, the liver says I don't know what to do with all this sugar, so it starts to metabolize it in unusual ways and it gets turned into what are known as low density lipoprotein particles. And that's the worst kind of cholesterol.

And for the body, a slice of white bread and a packet of sugar are essentially indistinguishable. The body receives them as the same. White bread – those kind of carbohydrates, for the body, are sugar?

It gets turned into sugar just the same way, and maybe a little bit of a time delay so to speak. But you can trace the sugar, whether it be in that bread or a packet of sugar, and you can find those same particles in those cholesterol particles later on.

    I wonder why humming birds and ants love sugar so much? And does sugar hurt them too?

    These articles always "kill" me because they don't tell the full truth. Ever watch when they say " there's this much sugar in a can of soda" and the poor out processed can sugar. Most drinks are made with corn syrup. This syrup is fructose. Sugar is Sucrose (dextrose). There is lactose which humans don't digest, glucose, maltose, and other forms. Some are monosaccharides and disaccharides. I body does react to different sugars when processing. All fruits and veggies have some form of sugar and sugar is a carbohydrate. Then there is fat that we need and fat that we don't. To much meat and protien will kill you too. Humans can survive without meat but they can't survive without fruit and veggies. They should be telling what to eat. I could go on and on so in simple words eat and exercise. Don't over eat and lay around .

    The right kinds of sugars and fats are essential for good health. Too much of anything is bad, including water and oxygen. You will turn all kinds of food into body fat if calories in exceeds calories out. Humans need a balanced diet to be healthy, that includes carbohydrates (sugars), protein, and fat. The carbs should be coming from a variety of fruits, vegetables, and grains, not a bag of Doritos and a Mountain Dew thirstbuster.

    A wonderful source of carbohydrates is beer.
    In Germany, beer is considered food. It is especially beneficial in nutrition because its alcoholic content induces relaxation and lowered metabolism, encouraging the storage of calories in the tissues of the body as God intendeded.
    We are rendered more pleasant and nonthreatening in appearance by adequate consumption of beer, therefore socializing more easily and stimulating our economy.

      Alcohol also reduces fear, Joey. And is why we old drillers drank. Even being limited to 3 shots of imported Jack Daniel's imported whiskey per day while drilling in Bavaria during Oktoberfest. (during breakfast)

        @ LaBella:
        Three shots of whiskey a day is just medicinal, you know.
        Alcohol is known to benefit heart function, body-mass index, dental hygiene, gait, and halitosis.

    The hedge fund Starboard Value says Olive Garden restaurants lack training and discipline and that servers bring too many breadsticks to tables at a time.

    The same guys who said take out a few toilets on the jet and put in more seats , just because you can make a profit on corporate prison's doesn't give you the right to make bad Italian food !

    Did Mitt Romney say that ?

    I lost over 30 lbs. using a kind of Atkins diet. I watched my carbs like a hawk, especially simple carbs. I could never lose weight with the calorie counting or low-fat diets, but with low-carb, the weight came off so fast I worried I was somehow sick. But I hadn't felt as good since high school. Kept the weight off now for three years.

      @ Nelson has discovered The Truth about nutrition and the weight of human bodies.
      For nutritionists. The Truth must accommodate the reality of Liability, Lawsuits, USA Government Guidelines, Court Decisions, and Mandated Carbohydrates.

        Sixty grams of carbs are contained in one baked potato of medium size, without butter or chocolate fudge on top.

        If you have to choose between butter, chocolate fudge, and bacon to flavor your 60-carb-gram baked Idaho potato, forego the fudge.

    While excess fat/obesity is responsible for over 40% of all healthcare costs, it is lack of tears/empathy that is behind hardened hearts...not sugar. Tears carry away toxins that build-up in our hearts just as perspiration does for our bodies.
    DANGER: Acetaminophen found in most pharmacy products inhibit tears from forming. And in most Rx prescription painkillers and antidepressants not only inhibit tears but also cause weight gain and brain damage.

    Let's see...sugar is a natural substance. Pharmacy drugs are petrochemicals laced with addictive substances. It's a no-brainer.

    Odd that only humans of the animal species are drug addicts/avid pharmacy goers.
    One would think quite the opposite since humans are so much more "evolved" than the "weaker" species.

    This is huge misinformation the fat was not replaced with sugar whitch need i remind everyone is not bad for you in fact it's a carb which is necessary for your body and comes in complex and simple forms whitch give loads of energy and are actually good for you. What they did replace the fat with was sodium to maintain flavor whitch is also necessary but easilly used in eccess whitch is why people got worse when all the diet products came out, they were getting too much sodium but carbs should take up at least 70% of your intake and that's pushing it to the least. This is because our bodies are highly dependant on carbohydrates for energy consumption we are designed to consume sugars and starch for the majority of our diets.
