Putting down the salt shaker & skipping sugar in your coffee
is a step in the right direction, but that's not where most people get the majority of their salt & sugar. Sodium & sugar are rampant in most packaged foods from pasta sauce & mac & cheese to rice mixes & soups. Start by checking the nutrition label on your breakfast cereal (some pack up to 20 grams of sugar per serving!).
Here's a quick tip: Divide the amount of sugar in grams by 4 & you get the number of teaspoons. Would you really pour 5 teaspoons of sugar into your cereal bowl?
