Renal Diet 101: Pizza

Most people, if not everyone, can’t deny having tasted at least a single slice of pizza.

The sight and aroma of the combination of cheese, bell pepper, tomatoes, and other choice ingredients on top of a circular flatbread, baked to goodness, is enough to make some stomachs growl in anticipation.

Truth be told, pizza has gone through a lot of changes and variations ever since it was first created in that, one can say, "there is a flavor of pizza for everyone."

But for someone with a kidney condition and on a renal diet, can pizza still be a food option?

A Brief History of the Flatbread

Modern day pizza, or the beginnings of it, started in Naples, Italy. This was based on the Greeks’ way of using bread for relishes. This was refined even further by Romans, where they used a sheet of fine flour, topped with cheese, honey, and bay leaves. Neapolitans also added tomatoes to the recipe.

However, it wasn’t until 1889 that cheeses became an official part of the pizza recipe. This was due to the Royal Palace’s request to Raffaele Esposito, a Neapolitan pizzaiolo, that he make a pizza for Queen Margherita’s visit. The result is a pizza greatly favored by the Queen, bearing the colors of Italy -- with basil (for green), mozzarella (for white), and tomatoes (for red).

Ever since then, pizza has gone through so many variations, especially when it was adopted as a beloved snack by the Americans.

Some common types and flavors of pizza are the following:

  • Pizza Margherita (authentic Neapolitan pizza)
  • pepperoni (most common topping in America)
  • Hawaiian (pizza with pineapple chunks)
  • meat-lover's

And that's just 4 of the most common ingredients. This doesn't even include the components used to make the bread itself, and the amount of salt needed to season the whole dish.

It's unfortunate, really, but if you want to slow down your kidney deterioration, pizzas are a no-no for you.

Pizza Alternatives

The good news is, you can try and cook your own version of pizza at home. Here are some suggestions to keep in mind when making homemade pizza:

  • Choose low-potassium toppings like green peppers, leeks, onions, and/or pineapples.
  • Fresh meat toppings like chicken, beef, and some fish have lower sodium content compared to pepperoni, bacon, ham, and such.
  • Avoid extra cheese toppings.
  • As an alternative to tomatoes, try using garlic or pesto.
