Do you drink sugary drinks? Some argue that sugary drinks play a significant role in today’s obesity epidemic in the US. Why? Because when you drink sugar, you are consuming calories. And, your body doesn’t feel as full when you drink these calories compared to when you eat the same number of calories as food. 1
That’s why I am excited about a new study that came out of the Harvard School of Public Health Prevention Research Center last week (and, I’m a co-author!). Researchers took a look at standards passed by the Boston Public schools more than ten years ago that stopped the sale of sugary drinks in vending machines, on a-la-carte lines in the school cafeteria, and in school stores. And about five years ago, the Boston Public Schools expanded the policy. When the policy was expanded, Boston Public School district staff also provided trainings and tools to help schools carry out this policy.
So, what did the study find? After more than ten years, the standards are still in effect. And, researchers found that the majority of schools are following the policy. As a result, about 85% of the students in the school district – more than 47,000 students – did not have access to sugary beverages at school.
What does this mean? The more access that children have to sugary beverages at school, the more likely they are to drink sugary beverages. 2 And, this matters for a number of reasons. Healthy drinks like water have amazing benefits – from regulating your body temperature, to providing cushion for your joints, to getting rid of toxins. In fact, a study done on sixth grade students showed that dehydration impacts performance on cognitive tests. 3
What do you think? Is it possible to offer healthier drinks (not sugary drinks) as the only choice at school?
