The Biden administration is set to announce on Monday the biggest increase (29.75%) to food stamps in the history of SNAP, the Supplemental Nutrition Assistance Program. It's a move that will help 42 million Americans.

The average SNAP benefit was $121 a month before the pandemic. It will increase in October to $157 a month. The boost is part of revisions to the Department of Agriculture's Thrifty Food Plan.

The Thrifty Food Plan, the basis for allocating food stamp benefits, is one of four USDA-designed food plans that specifies the categories and amounts for adequate nutrition.

The increase in food assistance was first reported by the New York Times. Agriculture Secretary Tom Vilsack on Monday is expected to make an official announcement of the plan.

"A modernized Thrifty Food Plan, based on current food prices, consumption data, the nutrients in food, and the latest dietary guidance, is more than a commitment to good nutrition – it’s an investment in our nation’s health, economy, and security," Vilsack posted Monday on Twitter.

Poverty and food security activists have argued that there have not been enough funds in the SNAP program for recipients to fill their carts with healthy food choices.

The $36 increase received positive feedback from Democrats on social media.
