A new bill proposes a two percent sales tax increase on various junk food items on the Navajo Nation.

In a press release, Council Delegate Danny Simpson, who is sponsor of the Healthy Diné Nation Act of 2013, said the legislation, if approved by the Navajo Nation Council, is one way to fight the diabetes and obesity epidemic on the reservation.

The revenue from the tax would go to community wellness projects, according to the release.

A spokesman for the tribe said the council will review the junk food tax in the coming months, but a firm date is not set.

Opponents of the bill said if it passes people will buy junk food off the reservation equating to lost revenue for the nation.

Lawmakers in Mexico approved new taxes on sugary drinks and junk food last month in an effort to combat rising rates of obesity and diabetes in their country.
