A few things we follow in her diet are:
1. We flavor with fresh diced onion, variety of diced peppers (not spicy though). We avoid any seasoning at all, even the Mrs. Dashes is not too good for you, but an option for those who need a little more taste.
2. Cauliflower - we steam fresh cauliflower (no seasonings added ) / a little lemon or lime juice gives it just enough extra flavor for her. But if you steam it correctly, I find I don't need to add anything.
3. The dieterian highly recommended any fruits or veggies that have a high water content - CUCUMBER & CELERY came the highest recommended.
The dieterian says some fruits like watermelon don't have the highest nutritional needs but a good healthy snack if avoiding the normal package snacks.
4. Steamed Cabbage
5. Kiwi - no highly recommended if your kidney has long term issues, but since her numbers are back to normal, we have found this as an alternative to fresh apples. It also helps regulate your blood pressure.
6. As you already do, limit her protein. On top of sodium, protein even fresh can carry high amounts of potassium and other vitamins. If she does eat it, it's a little portion with fruits and veggies on the side.
7. Yourget but still have to be on the caution side if taking any type of medication that could impact your potassium levels.
8. Apples - though she struggles with missing teeth, we have her eat an apple a day. If she has applesauce at all, it has to be unsweetened and unflavored. She doesn't like the sugar additives at all with her applesauce.
9. Brown rice - our alternate to a lot of those pasta products. No white rice since white rice is basically sugar. We have tried the noodles made with veggie base like spinach, but we were advise to stay away from pasta dishes.
10. IF we season the food, I use BASIL. Basil has just enough of the sweet taste as well as an anti-inflammatory.
The best trick for my daughter is to make smoothies with both veggies and fruits that would best with her. We did find out the hard way that too much celery can take away from the other flavors. Unlike most people, I just use a little bit of water & a tray full of ice cubes to make the smoothie.
Also because some veggies have considerate amounts of sodium compare to others, my daughter has a container in the fridge that was filled with serving size sandwich bags. This way if she wanted carrots, we knew she was only get the 45mg of sodium. Cauliflower also has a higher sodium content like some other veggies.
As far as nots for her:
1. We avoid any processed foods as much as possible. I aim for fresh fruit and veggies in her lunch.
2. I avoid as much dairy and bread products, but thankfully she doesn't take sandwiches to school.
3. I avoid all sugary drinks in general. If she was having issues with her water intake, we were told to put fresh fruits or veggies into the water to flavor it; and to avoid any of those Crystal Light or other similar products at all cost. Even advised not to buy those fruit juices you would find in the fresh produce area (hence, the smoothies).
4. Most dairy products are no-no for her.
You're pretty much following the same thing as us, but each child has their own likes and dislikes. I found that the more fresh fruit and veggie diet we follow, the more she doesn't go after the normal prepackage or processed snacks and actually goes for the fruits/veggies. I also found that her ankles don't hurt as much. She dances, so there's additional stress on her ankles which are her main complaints, but the doctors warned me that her joints make take awhile to recover.
And like you asked the ped doctor, ranitidine has been used just because there are some fruits or veggies that can have high acidity level depending on you make it. My daughter loves her oranges, sliced tomatoes, etc. but if she eats too much of them, she complains. Half a tablet of the ranitidine does the trick. Unfortunately I cannot avoid some healthy foods because they are better than the alternate.
Going out to eat meant only going to one diner for us, because we are friends with the staff. The manager has a special meal that they would make just for her, and still still wouldn't feel left out. The manager only serves fresh fruit so it was a plus for us (no canned fruit).
We normally logged no more than 1100-1500mg of sodium/day, but only with the right planning. As a family of 6 of us, we as a family took on her diet as much as possible. Having a toddler means they have some needs that I needed to still address. Thankfully after six months, we have learned the basics of what products to try or stay away from in general.
