In the U.S. sugar consumption is up and so is childhood obesity. Too much sugar can contribute to obesity and according to recent research there are more problems.

According to the FDA, in the last seven years, sugar and sweetener consumption has increased by nearly 20 percent, mainly high-fructose corn syrup, a low-cost substitute for sugar in beverages. A new study shows too much added simple sugar can negatively affect your blood pressure.

"Simple sugars have an effect on the elasticity of the blood vessels how they expand and contract and if your blood vessels are contracted, your blood pressure will be up," said dietician Judith Siler.

Nine thousand people were followed for 18 months. People with diets high in added sugar were found to have an increase risk of in obesity, high triglycerides, high blood pressure and stroke.

"In this study people who have a high simple sugar intake their blood vessels are more apt to stay contracted," Siler said.

The main culprits are juice drinks and soda. In a 12 oounce soda contains 10 packs of sugar. In order to cut down on your child's sugar consumption some experts say keep sugar beverages out of house especially soda and items like Gatorade.

"Sweetened juices, the Sunny Delight. They will drink Kool-Aid. They will drink Gatorade thinking they will get muscle and get big they are going to get big but I don't think in the way they are expecting. It's not to going to gain muscle mass," said Siler.

Experts say while soda should be limited, moderation is key.

"An occasional soda is not going to hurt somebody but be aware of the calories you are taking in and what you are drinking because you don't realize how many calories you are taking in," said Siler.
