It took over 20 hours of personal research to produce the "High Potassium - Low Calories Food List". You won't find anything else like it on the internet. I hope it helps you achieve your daily potassium goal. It's helped me where I'm no longer concerned about getting enough.
Drinking a lot of water (4+ cups) within a short period of time (~30-60 mins) will prevent your body from using it properly. It is MUCH better to spread your water intake over the whole day. This allows your kidneys to use it properly, instead of releasing unprocessed water and dehydrating you. If you drink throughout the day while eating, you replenish both sodium and water in your kidneys to keep them functioning properly.
Cutting out salt will actually increase your chance of heart disease and fat retention and slower metabolism, among other things. I used to do no salt than did some research and now eat a lot of salt. (see additional note for women)
Almond butter is a great substitute for peanut butter. Amazingly enough, it has 0g of sodium!
I added up the calories, nutrients, etc. for my own recipes and entered them in my nutrition tracker. What a shock! Although I add no extra salt, my own soups had more sodium than Campbell's--because I use bouillion and canned ingredients. Even switching to the low sodium broths didn't help all that much. I read a SparkPeople Article that suggested avoiding canned vegetables and beans and using frozen vegetables and dried beans instead. What a difference it made in the sodium count.
On your nutrition tracker page, there's a link near the top to "change nutrition goals". Clicking that link takes you to a page where you can add any of dozens of nutrients for your nutrition tracker to calculate. Examples are calcium, iron, magnesium, sodium, potassium, glucose, sucrose. The additional nutrients show in the chart at the bottom of your nutrition tracker page and help you watch your daily intake.
In addition to tracking calories, fat, carbs, and protein... keep track of your sodium intake too. It's very easy to stay within your calorie range but majorly exceed your recommended daily sodium allowance. By monitoring this, I have doubled the amount of weight I have lost in half the time!
For my husband's health we had to cut down on salt. I've lost almost 30 pounds in the last seven months. Cutting out foods that had high sodium also meant healthier choices, too (e.g. no fast food or frozen dinners), so that helped in the weight loss also.
