Key Takeaways

People living with rare kidney diseases like C3G and IC-MPGN often find that everyday food choices, especially those involving sodium, can have a big impact on their kidney health.

View all takeaways

Living with a rare kidney disease can make everyday food choices feel complicated. Many people with complement 3 glomerulopathy (C3G) and immune complex-mediated membranoproliferative glomerulonephritis (IC-MPGN) worry about how a lifetime of food choices will impact their kidneys.

One helpful place to start is by cutting back on sodium. Here’s some background on sodium and low-sodium meal ideas with plenty of flavor.

What Is Sodium and Why Does It Matter?

Too much sodium can worsen swelling and high blood pressure, two common problems with C3G and IC-MPGN. A high-sodium diet promotes fluid buildup and puts added strain on the kidneys. Over time, too much sodium can accelerate kidney damage.

When you hear “sodium,” you probably think of the salt shaker. But sodium is a natural mineral. It’s found in many different foods, even some you might not suspect.

Check the Sodium Content

When buying packaged foods, you can find sodium listed on the Nutrition Facts label. Generally, foods with 240 milligrams of sodium or more per serving are on the high side and should be avoided.

You can look for foods marked as “low sodium” or “sodium free.” Compare different brands and be mindful of your portion sizes. Also pay attention to the serving size listed on the label, as eating more than one serving increases the amount of sodium you consume.

Processed foods and restaurant foods tend to be high in sodium. Sodium adds flavor and extends the shelf life of packaged products. Limiting your intake of canned foods and frozen meals and eating out less can help you cut back.

Make Your Own Meals

Cooking fresh foods whenever possible gives you more control over your sodium intake. Here are some recipes to get you started.

1.5 cups of all-purpose white flour

Spray the muffin pan or set up the muffin papers for 12 regular-sized muffins.

Ingredients

1 medium onion, chopped
1 tablespoon of unsalted butter

Chicken in Wine Sauce

Wine and sodium-free seasoning boost the flavor of this high-protein meal from the American Kidney Fund. This flavorful dish takes around 65 minutes to prepare and cook. Watching your protein intake? Find out from your dietitian what the right serving size is for you.

Ingredients

2 tablespoons of canola oil
½ cup of all-purpose white flour
¼ tsp freshly ground pepper
6 chicken thighs (bone-in, with the skin)
4 cloves of garlic, peeled and halved
¾ cup white wine, divided into ½ cup and ¼ cup
1 teaspoon of Mrs. Dash garlic herb seasoning mix

Instructions

Heat the oil in a large skillet over medium heat.
Place the flour and black pepper in a dish.
Coat the chicken in the flour and place it in the skillet.
Cook the chicken skin-side down until golden brown.
Flip the chicken and continue cooking.
Add garlic cloves, ½ cup white wine, and Mrs. Dash seasoning.
Cover and cook chicken on low heat until it reaches 165 F (about 20 to 40 minutes).
Check the temperature as you go. Thighs that reach 165 F should be removed and set aside while you finish cooking the rest.
Add the remaining ¼ cup of white wine midway through cooking.
Top your finished chicken with the wine sauce from the skillet and enjoy.

How Much Sodium Can You Have?

Your specific sodium restrictions depend on your diagnosis and level of kidney function. After reviewing your lab results and medical history, your healthcare provider can make recommendations for you.

In addition, some people with advanced C3G and IC-MPGN need to consider more than just sodium. You may need to follow a low-potassium or low-phosphorus diet too.

Ask about meeting with a registered dietitian to make meal planning a little less stressful. They can help you make a grocery list, find recipes, and learn how to eat well for your condition.
