Avoiding fast food not only helps lower your calorie intake and the consumption of mystery ingredients, it also supports your general health, too. Fast food is notorious for being high in sodium and saturated and trans fats. Too much sodium increases blood pressure and too much fat increases blood cholesterol, which are two factors for increased heart disease risk. The daily recommended intake for sodium is 2,300 to 2,400 milligrams while saturated and trans fats should respectively be limited to less than one and seven percent of your total daily calorie intake. Many fast food restaurants have menu options that exceed these amounts.
