You might have read or heard recently that the city council in Berkley, Calif., will vote this evening to add a soda tax to the list of initiatives that will appear on the November ballot. Some elected officials in Berkley think that a soda tax will help people get fit. But common sense tells us that we need to balance calories consumed from all foods with the calories burned through physical activity and exercise in order to maintain a healthy weight. If we want to get serious about obesity, it starts with education – not laws and regulation. Singling out soda and other sugar-sweetened beverages for an additional tax will do nothing to improve people’s health. These politicians should focus on what matter most – education, jobs and the economy – and leave the grocery shopping to us.
