Tomatoes are considered a high potassium fruit, known to raise potassium levels if not consumed moderately. Kidney disease sufferers often ask if they should avoid tomatoes, marinara sauce, or any other type of tomato sauce. 

In this video today, you will get a better understanding of the right way to enjoy tomatoes. Generally, the larger the tomatoes are, the more potassium they carry and vice versa. 

While maintaining a renal diet, you’re allowed to have small portions of tomatoes as long as you control the quantity and sizes of the tomatoes. For example, Roma tomatoes are a much smaller type known to have around 200 mg of potassium in one tomato. You can very easily include these types of lower potassium tomatoes in a salad, sandwich, or whatever your preferred food is. 

Kidney disease sufferers should not be scared as enjoying small amounts like Roma tomatoes or a half cup of tomatoes would generally be considered safe. If you’re someone looking to strictly restrict potassium intake, you should avoid it altogether. 

Marinara sauce may be hard to avoid but it packs an extremely high amount of potassium. It can have upwards of 1000 mg of potassium in one cup. Generally, marinara sauce, pasta sauce, and spaghetti sauce are recommended to be served in small amounts (about a quarter cup). 

With tomatoes and a renal diet, you can include small portions and do just fine. However, for kidney sufferers, you should always try to avoid large amounts of marinara sauce due to their deadly potassium content.
