Answer:
Dietary sodium only comes from 25% of the table salt we add to our food. The other 75% comes from the process food such as take-out that we, and Bill, eat.
Explanation:
This is because sodium is added to preserve the freshness of the process, enhance the thickness of the products and to cover up any bitter aftertaste, if present, and enhance the flavour of the food. Therefore, in order for Bill to decrease his sodium intake he needs to cut back on the packaged food he eats daily. A better alternative would be to eat more fresh fruits, vegetables and salads. He should also avoid using condiments when he does get take-out as these are heavy in sodium. Instead, Bill can carry with him his own salt-free sauces. Products such as milk and coffee are also low in sodium. If he wants to be more conscious about the food choices he makes, he can also ask for the nutrition menu when he eats out so that he can determine exactly how much sodium he is consuming.
