WIC food packages and nutrition education are the chief means by which WIC affects the dietary quality and habits of participants. Did you know that these two benefits are among the top reasons for continued participation in WIC (in addition to the work of WIC personnel!), and that consistent 4-year participation in WIC was associated with better diet quality?
Eye on Nutrition brings focus to the foods and nutrients in the WIC food packages to shine a light on their importance to WIC participants. Potassium is a nutrient of public health concern across the lifespan. Luckily, it’s in many WIC foods. Be sure to check out potassium-rich recipes members of the WIC community have shared with us.
Potassium is an essential mineral, is in all body tissues, and is required for normal cell function. It helps to balance out sodium and offset the negative effects of salt on blood pressure.
Potassium is a key component in the functioning of:
- Muscle contraction
- Nerve signaling
- Fluid balance
Potassium plays an important role in lowering blood pressure, thus reducing the risk of heart disease and stroke, but controlling high blood pressure during pregnancy is also important for mom and baby.
For mom, complications of high blood pressure during pregnancy include eclampsia, stroke, the need for labor induction (giving medicine to start labor to give birth), and placental abruption (the placenta separating from the wall of the uterus).
For the infant, complications of high blood pressure during pregnancy include low birth weight and preterm birth.
While other factors also affect blood pressure, increasing potassium (and reducing sodium) in the diet can help control high blood pressure (spoiler alert: foods high in potassium are naturally low in sodium).
Getting too little potassium can also deplete calcium in bones, and increase the risk of kidney stones.
The daily recommended amount of potassium is based on gender and age, with pregnant women needing the most at 2,900 milligrams (mg) per day, and breastfeeding women needing 2,800 mg per day.
A number of WIC-eligible foods contain potassium, though not all foods may be available in every State, US Territory, or Indian Tribal Organization due to the flexibility they have in selecting foods for their WIC food packages. Among the WIC-eligible foods that provide potassium are:
- Legumes (beans, peas and lentils)
- Vegetables (including soybeans*)
- 100% juice
- Milk and milk substitution options:
- Soy beverage
- Canned fish, particularly sardines
*Technically soybeans are in the legume category, but they can be purchased with the CVV since they’re only available in fresh and frozen forms, so we included them here! Foods beyond those in the WIC food packages that have potassium include cashew nuts, seafood, meat and poultry.
Mention "a high potassium food" and many people often think first of a banana, but a number of fruits and veggies (and other foods) have more potassium than this staple fruit. Below is a sampling from this list from the Dietary Guidelines.
Beet Greens (1 cup)
Lima Beans (1 cup)
Swiss Chard (1 cup)
Sapote or Sapodilla (1 cup)
Guava (1 cup)
Kiwi (1 cup)
Cantaloupe (1 cup)
Banana (1 medium)
Help your participants explore vegetables and fruits that are in season with the Seasonal Produce Guide.
Get inspired by WIC State-developed resources, including yearly farmers’ market cookbooks, and share them with your participants. (Examples of farmers’ markets training materials are also available for those interested in what other WIC State agencies are doing.)
Keep Nutrition Facts label fact sheets for vitamins and minerals handy. These provide action steps for consuming a diet rich in vitamins and minerals (including potassium), and charts that identify food sources of each vitamin and mineral.
