“Convenient snacks can be higher in refined carbohydrates with excess sugar and sodium,” says Edith Yang, RDN, who specializes in kidney disease and diabetes in Monrovia, California. And classic low-carb snacks like beef jerky may have more protein and sodium than you should eat.
The healthiest snacks offer some complex carbohydrates to supply you with energy, mixed with some protein, healthy fats, or fiber to slow your blood sugar response, says Yang. Keeping your blood sugar on target is a key to maintaining kidney health when you have diabetes. Also, she says, look for snacks that have 200 milligrams (mg) or less of sodium, as too much salt stresses your kidneys.
Although finding snacks that fit the bill may be tricky, “there are many different ways to put together something easy and quick,” Yang says. And it’s important to note that people with a more-advanced stage of kidney disease, including those on dialysis, may have additional dietary recommendations that they need to juggle. If that’s you, then you may need to limit how much potassium and phosphorus you get from food, for example.
The recommendations below may not work for everyone with CKD. So, it’s critical to ask your doctor or a dietitian for a personalized eating plan.
Roasted Legumes
This trendy snack is typically chickpeas, fava beans, or soybeans that have been cooked without oil. They have a crispy texture, come in a variety of flavors, and contain a diabetes-friendly mix of plant-based protein and dietary fiber.
“It’s a shelf-stable source of these nutrients, so it’s something you can keep in your desk, the car, or your bag and take out when you need it,” says Yang.
Look for brands that have 200 mg or less of sodium to help protect your kidneys, says Yang.
Popcorn
When you’re living with diabetes, it may be healthier to balance popcorn with a small handful of almonds or peanuts for protein and more fiber. If you have a sweet tooth, toss in a few chocolate chips — a small amount helps limit added sugar — or dried fruit for a nice sweet-salty combo that will help tide you over until your next meal.

Hummus and Veggies
Yang recommends this winning combo for a quick snack.
It’s also easier than ever to find individual snack packs of both raw, cut vegetables and hummus dips. So, aside from taking both out of the fridge and putting them into a bag (maybe with an ice pack if you’re going to eat it later), there’s no prep required. You can even find little snack trays that pair hummus with crunchy veggies.
A Nut, Dried Fruit, and Cheese Snack
This snack combo is good for people with diabetic kidney disease, because it is jam-packed with nutrients and won’t spike your blood sugar.
A cheese stick, plus a half ounce (oz) of unsalted nuts — pistachios, cashews, almonds, walnuts — and a tablespoon (tbsp) of dried fruit for sweetness — such as raisins or cherries — creates a complete snack. It has a nice balance of complex carbs, protein, and healthy fats.
“You can make a mini cheese plate to take on the go,” says Allison Beach, RDN, a certified specialist in renal nutrition in Carrollton, Texas.
If you’re not able to make a portable snack, look for ready-to-eat versions of this combo at the grocery store. Beach suggests choosing the products that have cheese, nuts (the kinds that aren’t honey-roasted), and dried fruit for a blood sugar–balancing snack that limits added sugar and sodium. You’re better off skipping those that have chocolate or crackers.
Apple Slices With Nut or Seed Butter
Sliced apples are available in single-serve bags at many grocery stores in the refrigerated section of the produce aisle. And many brands of nut butter come in individual, squeezable packets.
Sugar–Free Snack Bars
It’s best to be careful in the snack and energy-bar section of the grocery store. That section is full highly processed foods that could have more sugar or protein than you should eat.
When considering snack bars, be sure to read the nutrition facts labels. Also, think about following Beach’s 10-and-3 rule. “Look for something that has less than 10 g of added sugar and at least 3 g of fiber,” she says. The best choices will rely on nuts, seeds, and dried fruit for flavor.
And when you’re living with kidney disease, you should be suspicious of the trend that tries to pack as much protein as possible into these energy bars. “Many protein bars may not be a good option,” says Beach.
Yogurt Drinks
As always, please stay away from options with more than a little bit of added sugar. Luckily, yogurt brands love to target health-conscious customers with zero-sugar options that are sweetened with trendy alternatives like monk fruit and allulose.
The Takeaway
- People with diabetic kidney disease need snacks that balance blood sugar without overloading their kidneys. This means eating choices with low added sugar and sodium, plus moderate amounts of protein to avoid kidney strain.
- Advanced kidney disease may bring additional restrictions, such as a limit on how much phosphorus and potassium you can eat.
- Smart grab-and-go snack choices include dry-roasted legumes, popcorn, hummus and veggies, nuts and cheese, yogurt, and protein bars.
- Aim for snacks with under 10 g of added sugar, at least 3 grams of fiber, and lower sodium to support blood-sugar management and kidney health.
