8 Easy Grab-and-Go Snacks for C3G/IC-MPGN

“Berries are one of the highest fiber fruits,” Evink says. “Fiber is extremely important with kidney disease because it can help support regular bowel movements.”

Evink also says that constipation can contribute to high potassium, which can be dangerous if not treated.

“Therefore, making sure to consume meals and snacks that contribute to a higher fiber intake is a good preventative strategy,” she says.

Similar to fresh fruit, raw vegetables are whole, unprocessed foods that are generally low in phosphorus and sodium, and many are low in potassium. They are rich in nutrients and fiber. Evink points to cucumbers and carrots as a particularly good snack.

“Carrots and cucumbers are low sodium, low fat, and low protein,” she says. “Plus, they're nonstarchy vegetables that won't have an impact on blood glucose levels for those who are diabetic.”

“Nuts are a good source of healthy fats and plant-based protein,” Evink says. “While protein intake should still be monitored, plant-based protein is a much better option to maintain lean muscle mass compared to animal protein sources.”

Rather than choosing flavored yogurts, which can contain sugar and other additives, add some fresh berries to plain yogurt. You can also add walnuts, sunflower seeds, or chia seeds for texture and to boost nutrition, and give it extra flavor with a sprinkle of cinnamon, vanilla extract, or nutmeg.

Movie theater–type popcorn tends to be drenched in butter, salt, and even artificial flavorings. These can give you more sodium, calories, and unhealthy fats than you may intend.

As for store-bought popcorn, Evink recommends SkinnyPop.

“It's low-protein and so convenient, and you can even buy individual portion-size bags,” she says.

Store-bought trail mixes may include a number of salted nuts and other ingredients that you may want to avoid. Try making your own, choosing healthy ingredients that work best for you.

Garden suggests trying:

• Unsalted cereal, such as Original Cheerios and Corn Chex, which are low in sugar, sodium, and potassium.

• Lower-potassium dried fruits such as raisins or apples

A number of brands of crackers on the market fit the bill, Garden says. These include unsalted or low-sodium whole-grain crackers such as:

• Triscuit Hint of Sea Salt
• Wasa Multi Grain Crispbread
• Blue Diamond Almond Nut-Thins

Unsalted rice cakes can be a good choice, she says. Evink says that some graham crackers can also be a low-sodium snack.

“They can help curb a sweet tooth while offering a serving of whole grains,” she says. “Spread some nut butter on top for a more filling option.”

Although there are healthier alternatives, one of your best options is to make your own.
