An Illinois nutrition program is tweaking the diet of the low income residents it helps feed.

In a news release, the Illinois Special Supplemental Nutrition Program for Women, Infants and Children says that beginning Wednesday, many of those who receive food vouchers will be offered skim milk or one percent milk instead of whole milk in an effort to improve their health.

The release from the program called WIC says skim or one percent milk will be offered to pregnant women, new mothers, women who are breast feeding and children over the age of two. To insure proper growth and development, children between one year and 23 months will continue to receive whole milk.
