Health concerns In 2003, a report was commissioned by four U.N. agencies, the World Health Organization (WHO) and the Food and Agriculture Organization (FAO), compiled by a panel of 30 international experts. It stated that sugar should not account for more than 10% of a healthy diet. However, the Sugar Association[1] of the US insists that other evidence indicates that a quarter of our food and drink intake can safely consist of sugar. There is an ongoing argument as to the value of extrinsic sugar (sugar added to food) compared to that of intrinsic sugar (sugar, seldom sucrose, naturally present in food). The primary benefits of added sugar is usually taste, and the primary drawback is the additional calories. In the United States, sugar has also been attributed as a leading cause of obesity. Sugar and hyperactivity There is common belief among the general public, in the U.S. at least, that eating too much sugar (not only sucrose, but other varieties such as glucose) will cause some children to become hyperactive—giving rise to the term "sugar high" or "sugar buzz". Recent studies have not shown a link between the consumption of sugar and hyperactivity levels, even when the researchers focused on children with a presumed "sugar-sensitivity" [2]. The belief in the possibility of a sugar-high among parents and teachers may cause them to perceive children being more energetic and excited after consumption of sweets and sugary beverages through observer bias. Others believe that the hyperactive effects of sugar can be seen equally in children and adults. On average Americans eat or drink 5 pounds of sugar a month, drastically higher than 10 years ago due to the fact that sugar is in many foods under many different names.

Sugar, saliva, and bacteria lead to a formidable combination that may lead to tooth decay. After eating sugar, particularly sucrose, and even within minutes of brushing your teeth, sticky glycoproteins (combination of carbohydrate and protein molecule) adhere to the teeth to start the formation of plaque. At the same time millions of bacteria known as Streptococcus mutans also adhere to the glycoprotein. Although, many oral bacteria also adhere, only the S. mutans is able to cause cavities. In the next stage, the bacteria use the fructose in a metabolism process of glycolysis to get energy. The end product of glycolysis under anaerobic conditions is lactic acid. The lactic acid creates extra acidity to decrease the pH to the extent of dissolving the calcium phosphate in the tooth enamel leading to the start of a cavity. Source So apparently sugar is quite a source of energy for the bacteria responsible. Perhaps the frequency of consumption would be more of a factor than quantity - I mean I can't imagine the bacteria guzzling the stuff down, but a steady supply of sugar would most certainly keep them in tip-top shape!
