According to the American Heart Association, a healthy American adult should eat less than 2300 mg of sodium per day.
2300 mg?! That's a lot, right? Not really. Sodium is in everything. You really have to pay attention to the nutrition facts on foods to make sure you're not getting too much. Stay away from processed foods, which is basically almost all of the food in the center aisles of the grocery store. If it comes in a box, it is likely processed.
If you're a fan of the easy frozen dinners, watch it. They pack a lot of sodium. Take for instance, Lean Cuisine's Sesame Chicken. It has 650 mg of sodium which is 27% of your daily allowance. Remember, this is just one meal. If you eat a couple of these in one day PLUS your other food you need to be eating, you are likley to go way over your daily allowance.
You don't want your diet to constantly contain high amounts of sodium becasue too much sodium in the diet leads to high blood pressure which then increases your chances of having a stroke or heart attack.
So, just try to keep this in mind the next time you're buying food and planning your meals. Low soduim!
