My wife is wanting some advice on recipes

My best advice is to stop putting salt in things, and not buy pre packaged foods. Those are LOADED with salt. If she's making something like baked chicken, use Mrs Dash seasoning....they don't have any salt in them, and they're DELICIOUS! And tell her to drink tons of water. My ankles swelled up REALLY bad with my pregnancies, and they didn't go down until about 2 weeks after delivery. And have her put her feet up above her heart...that will keep some of the swelling down.

Agreed with prior posters. The more you can cook from fresh ingredients and avoid processed food and eating out, the less sodium you will have in your diet. Don't add salt to foods, but use Mrs. Dash or other seasonings to add flavor. Get low-sodium versions of things you do use to cook (chicken broth, etc.... or I suppose you could make your own but that never seems to work for me!) Tell her to stay off her feet when she can too (and do things to help her be able to do that!). I had a lot of swelling/water retention the last few months of pregnancy... the good news it is goes away after delivery but the months in between are no fun! (I also wasn't paying attention to not eating processed foods, etc at the time)
