Final answer:
Current evidence, particularly from studies like Wolraich et al. (1995), does not support the claim that sugar intake causes hyperactivity in children with ADHD. Therefore, the assertion that Mary should not feed her daughter with ADHD any refined sugar products to control symptoms is false.
Step-by-step explanation:
Research regarding attention deficit hyperactivity disorder (ADHD) and sugar intake has been subject to myth and misunderstanding. Contrary to popular belief, current evidence, including a study by Wolraich et al. (1995), does not support the idea that sugar causes hyperactivity in children. In fact, studies suggest that the link between sugar and hyperactivity is a common misconception, with little evidence to substantiate the claim.
Factors leading to ADHD and its behavior are complex and may involve genetics, environment, and lifestyle rather than just diet alone. Additionally, while dietary changes can impact overall health, singling out sugar as the cause of hyperactivity in ADHD lacks substantial scientific backing. The final answer to the question of whether Mary should avoid feeding her daughter refined sugar products specifically to control ADHD symptoms is: false.
However, promoting a balanced diet and healthy lifestyle, including reducing processed and high sugar foods, can contribute to overall well-being and may have indirect benefits for children with ADHD.
