It’s one thing to say a policy should work. However, do healthy food policies actually change what people buy? Mexico offers an important real-world example.
After the country introduced a tax on sugary drinks, purchases of taxed beverages decreased, with the largest decreases seen among lower-income households.
Purchases of untaxed beverages also increased during the post-tax period.
That matters because it shows that changing the food environment can influence the choices people make, not just in theory, but in the real world, leading to real change.
