Anyone on low sodium diet?

I'm 69 and was diagnosed with PAH (pulmonary arterial hypertension) nearly 2 years ago and PD (Parkinson's disease) 6 months later. It is essential for my lung and heart that I maintain a 1500 mg per day limit of sodium intake. I'd like to lose weight, also, but the shortness of breath and other symptoms of PAH are limiting my exercise. I use MFP mainly to create loso (low sodium) recipes. Are there others out there on MFP who might want to share loso tips and recipes?
