Strengthening Arguments on Sugary Drinks and ADHD Symptoms

Very Hard Critical Reasoning Strengthening Data Arguments

A recent study found that children who regularly consume sugary drinks are more likely to exhibit symptoms of attention deficit hyperactivity disorder (ADHD). Specifically, 40% of children diagnosed with ADHD reported daily consumption of sugary beverages, compared to only 20% of children without the diagnosis. This has led researchers to argue that reducing the intake of sugary drinks could lead to a decrease in ADHD symptoms among children.

However, this conclusion has sparked debate among experts. Critics point out that correlation does not imply causation and note that other factors, such as socioeconomic status and access to nutritious foods, could also contribute to the prevalence of ADHD symptoms.

Which of the following options would most strengthen the argument that reducing sugary drink consumption could lead to a decrease in ADHD symptoms among children?

A follow-up study finds that children diagnosed with ADHD who eliminate sugary drinks from their diet report a significant reduction in ADHD symptoms over a six-month period.

A separate survey shows that the majority of parents of ADHD children believe that sugary drinks are a major cause of their child's condition.

Research indicates that children with higher socioeconomic status tend to consume less sugary drinks and also show lower rates of ADHD symptoms.

An analysis reveals that dietary habits related to fruit and vegetable intake have no correlation with ADHD symptoms among children.
