5 Delicious Smoothies for People with CKD

5 Delicious Smoothies for People with CKD

Mmmmmmm, smoothies. The perfect breakfast or snack. But a lot of them contain too much potassium and phosphorus for folks with kidney issues need to avoid. To stay healthy, you need to know which ingredients to look for – and which to avoid.

How healthy are smoothies anyway?

Fresh fruits and vegetables include dietary fiber, and you can get a significant part of daily nutritional quota packed into one smoothie. But, like anything, too many sweet fruits or added sweeteners can up the carbs, and breakfast can quickly turn into dessert. Balanced ingredients and reasonable portions will keep things in check.

Can I drink pre-made smoothies?

Sure – but read the label. Bottled and fresh smoothies can contain fruit juice, sweeteners, dairy, plant milk, nuts/nut butter, seeds, tea, chocolate or supplements. Make sure your smoothies combine the ingredients that make sense for the kidney diet you’ve discussed with your doctor.
