Sugar is far more dangerous for our health than it was previously believed-not only does it rots our teeth and adds padding to our thighs, it can devastatingly alter our metabolism.
Both sugar and high-fructose corn syrup are equally bad because both contain about the same amount of fructose, he said. "This mutation that occurred 15 million years ago could explain why we`re fat today. It doesn`t mean we all become obese. It doesn`t mean everyone is going to get diabetes. It does mean that all of us are more susceptible to being fat than most other mammals," Discovery News quoted Johnson as saying. In the new study, the researchers identify just such a mutation that affects how our bodies deal with uric acid, an ordinary byproduct of metabolism. The mutation evolved 15 million years ago, during a period of starvation and is present on all of us. Johnson said that the mutation led to an increase in how much uric acid our bodies produce after eating fructose, while also lengthening the amount of time that uric acid sticks around after a sweet treat. The result is inflammation and an increased ability for cells to become fat. In other words, uric acid works within cells to amplify sugar`s ability to cause obesity, he said. Even on a calorie-restricted diet, animals that eat too much sugar develop insulin resistance, an early sign of diabetes, he said. Other trials in people have shown that lowering uric acid levels lowered their blood pressure. And like alcohol, the recent study found, sugar is also habit-forming and possibly addictive. The study was published in the journal Transactions of the American Clinical and Climatological Association. ANI
