How to Read and Understand Food Labels

In the local grocery stores, you can usually find many manufacturers of the same type of food especially the boxed cereal aisle where Kelloggs, Post and other brands are competing everyday with who has the healthiest, lowest sugar cereal on the market. Unfortunately, many manufacturers have forgotten about the consumer and have led them down the deception aisle.

Be Aware of Serving Size

The first thing to be aware of on a food label is the serving size - All the other specification like calories, fat, sodium, etc. are based of the serving size. Of course, you can get only 1-2 grams of fat in some products if the serving size is the size of a quarter. We know good and well that many of us will eat 3-4 times that amount and increase our fat to about 8-10 grams per serving. Depending on the other ingredients and what the food is, this could be a lot of fat for one serving.


The calories listed are for the serving size only - not the entire package. Of course, some items may say serving size: 1 bar or 2 - 1” pieces. Please be aware that the serving size is very important for you to determine how many calories are in that meal.

Carbohydrates, fats and proteins are listed by the weight in grams. For example, 5 grams of protein in one serving would have 20 calories for that serving:

  • 1 gram of protein = 4 calories

  • 1gram of carbohydrates = 4 calories

  • 1 gram of fat = 9 calories


The sodium on the food labels is something most people forget to look at. Unfortunately, many packaged products are loaded with sodium. Too much sodium in the diet can lead to water retention and possibly hypertension in some extreme cases. Be aware of a single serving size of sodium with 300 milligrams and above. The RDA (Recommended Daily Allowance) is 2,400 milligrams per day. This can be high if you are trying to lose weight or need to watch your blood pressure. One tablespoon of soy sauce has 2,000 milligrams alone. Can you imagine how much sodium you take in during one dinner out for Chinese food.
