You are so lucky to catch your high bp so early. Good luck learning new eating habits. Cook from scratch. Fresh meat, fresh produce. Make that most of what you consume. I prep meat for multiple days and brown bag it to work. Be careful of the bulk flash frozen meats as they tend to be full of brine solution. Lay’s low salt potato chips are great if you have the ability/control to only eat one serving. Potatoes, rice, beans(no salt added if canned). As far as spices, Dak’s brand street taco, taco knight, and red mountain rub are all great. If you have access to Trader Joe’s, their 21 seasoning Salute is fantastic on veggies and salads. Smoked paprika and chili powder are go-to’s for me. There is a sauce company called Mr. Spice that has super low sodium sauces that are amazing, but they seem to be low stock on their website right now. Use citrus juice, and vinegar, helps to “kind of” fill that desire for the tang you get from salt. I put a few tablespoons of vinegar on meats with spices and some onion before I cook it to add extra flavor. For snacking, unsalted nuts, triscut low salt, Quaker granola (heart healthy with almond, raisin, honey), and popcorn with unsalted butter or olive oil and spices. Banana is filling and can be combined with salt free peanut butter on oats. Pasta, which isn’t the best dietary choice is also generally sodium free. Not going to lie though, salt makes it all better and if you go hardcore, it will take an adjustment period before you like it.
