The study was based on food preferences from 2,000 participants (11 participants in each group), and included three main groups: those who tried to avoid sugar, chocolate, and other sugary foods; those who tried not to eat such foods, and those who didn’t try food items that were high in sugar, but did eat high in other sugary foods. There were no significant interaction terms involving alcohol, sugar, food type, or sugar sensitivity. Dietary fiber was assessed by the inclusion of the Dietary Reference Intakes (dietary fiber: 1.0, 1.5, 2.0, 2.5, and 3.0 mg/100 g or less).
Results of the study were consistent with other studies that have found a relationship between sugar and weight gain in middle-aged men with and without eating any type of fruits, vegetables, fish, or seafood. The prevalence of obesity is highest among individuals of lower socioeconomic group, and the prevalence of overweight and obesity among high-income individuals (14,15). The current study assessed the relationship between sugar and the risk of developing overweight and obesity with a subgroup of 12,800 people at high risk, who identified as white, white, and Hispanic, respectively (2,15,16).
A large, randomized trial was conducted to find a relationship between increased food intake and risk of becoming overweight or obese. This trial was designed to evaluate the associations of higher consumption of sugar and a number of other sugar-containing foods, including sugar-sweetened beverages, with risk of becoming overweight or obese (2). The trial included 39,000 American adults with an average height of 15.7 m and weight of 130.5 kg, healthy controls (12 males and 5 females) with a BMI of 22.4, and 18,800 randomly selected controls (4 males and 7 females) (3,16). Weight of the 12,100 participants was measured by hand on a computer screen in a research room.
