Latinos are a major participant in federal food assistance

Research on the impacts of healthy food financing initiatives among SNAP and WIC participants is important because a large proportion of them are Latino, and/or belong to underserved populations.

Latinos comprise 19 percent of SNAP and 32 percent of WIC participants.36,37

About 50 percent of U.S. Latino children are served by the WIC program.37

Efforts to promote healthier food via federal food assistance

In 2009, the U.S. government revised the “package” of food eligible for WIC food to include a wider variety of healthy foods, including whole grains, fruits and vegetables, and lower-fat milk.

Three studies found that the new WIC food package significantly improved the availability and variety of healthy foods sold in WIC-authorized stores and, to a smaller degree, even non-WIC convenience and grocery stores.38–40

Latinos benefit from these changes

One study showed that the WIC revisions made fresh vegetables more affordable in predominately Latino neighborhoods.41

Using pre- and post-revision store inventories to assess how the new WIC food package affected access to healthy foods in convenience and grocery stores in the state of Connecticut, a study found that the supply of healthy foods increased by 39 percent in lower-income areas. Moreover, improved availability and variety of whole-grain products were responsible for a majority of the increase in the healthy food supply.38

Another cross-sectional study of small, WIC-authorized food stores in eight U.S. major cities found that after WIC was revised, store managers reported increases in their sales of new WIC-approved foods, such as whole-grain bread, low-fat milk, and white-corn and whole-wheat tortillas.40 Although this study did not find changes in sales of processed fruits and vegetables, a pilot program implemented in New York State documented that the vegetable and fruit WIC vouchers were popular among stores that accepted them.42

The revised WIC food package also appears to be changing the diets of participating Latino and other children.

A longitudinal study of Chicago children observed a significant decrease in fat consumption and increases in fruit intake and dietary fiber among participating Hispanic children in Chicago 18 months after the WIC package revisions.30

A cross-sectional study, using a sample of California WIC participants, found an increase in whole grain foods, low-fat milk, and fruits and vegetables 6 months after the implementation of WIC revisions.43

Another cross-sectional study of children aged 2-4 in New York state found a 3 percent increase in consumption of low-fat or nonfat milk and steady increases in daily consumption of fruits, vegetables, and whole grains after the WIC revision was implemented. In the same study, the proportion of children aged 1-2 years and 2-4 years who were obese decreased by 6 and 3 percent, respectively.44

In contrast to WIC, SNAP benefits subsidize broad categories of foods and are not restricted to healthier options within those categories.

Two cross-sectional studies and one short-term longitudinal study found that participation in SNAP does not appear to improve the nutritional quality of adult or children’s diets.45–47

There are conflicting findings on whether participation in SNAP makes children more likely to become obese.48

One study found that Latino women participating in SNAP were 4.5 times more likely to have a child in the 85th percentile for weight than non-participants.49 However, a different study found that participation in SNAP significantly reduces BMI percentile and the likelihood for being overweight/obese for boys and girls ages 5-11 and boys ages 12-18.50
