Saturated fat. Usually solid at room temperature, saturated fats are found in animal products such as meat and milk, as well as in coconut and palm oil. Saturated fat is often used in foods to prevent rancidity and off flavors. No more than 5% to 10% of your total daily calories should come from saturated fat.

Serving size. This section of a nutrition label helps you determine the number of calories and amount of each nutrient in a recommended serving of a food. USDA serving sizes are often smaller than you might eat. So read labels carefully. Even small packages often contain more than one serving.

Sodium. While sodium (commonly called salt) is vital for healthy nerves and muscles, most of us get too much salt in our diet, often from processed foods. Read food labels to help keep your sodium intake to 2,300 milligrams a day or less. Persons 51 and older, African Americans, or people who have hypertension, diabetes or chronic kidney disease should limit sodium to 1500 milligrams daily.
