At home, you can eat only what is available. For your weight
management program to be successful, you must master the
art of low-fat shopping. If what you have in your refrigerator
and cupboards is junk food, chances are you'll eat that
in place of healthy, low-fat foods that satisfy and provide
energy.
Before you head to the store, you should have a clear
understanding of how to read labels so you can make the
healthiest, wisest choices of foods you will enjoy. The
following are key words for properly understanding food
product labels:
- Serving size: The amount of food the
information refers to.
- Servings per container: The number
of servings in the entire product or package.
- Percent daily values: Shows how a food
fits into an overall daily diet based on a daily intake
of 2,000 calories.
- Calories: The total number of calories
in one serving of this food.
- Calories from fat: The total number
of calories from fat in one serving of this food.
- Total fat: The weight of fat (in grams)
in one serving of this food.
- Saturated fat: The weight of saturated
fat (in grams) in one serving of this food.
- Sodium: The weight of sodium (in milligrams)
in one serving of this food.
- Protein: The weight of protein (in
grams) in one serving of this food.
- Total carbohydrates: The weight of
both complex and simple carbohydrates (in grams) in one
serving of this food.
- Sugars: The weight of simple carbohydrates
(in grams) in one serving of this food; to find out how
many complex carbohydrates are in the food simply subtract
sugars from total carbohydrates.
After you have a clear understanding of the key label words,
there are five other important values you will want to consider
before concluding that the food product is a healthy, low-fat
food.
1. Check the List of Ingredients:
Ingredients are listed in descending order according to
their quantity in that food. The first three or four ingredients
listed usually make up most of the product. Keep in mind,
however, that fat and sugar come in many different forms;
even if they are not one of the first three ingredients,
the food can still be very high in fat and/or sugar. Other
"names" of fat include hydrogenated vegetable
shortening, butter, margarine, oil (coconut, safflower,
palm, etc.), lecithin, lard, and cream solids.
Other names of sugars include fructose, honey, corn sweeteners,
molasses, maltose, corn syrup, fructose, galactose, glucose,
and dextrose. If only one of these names appears among the
first few ingredients on the label, or if several of them
are listed throughout the label, this food is likely to
be high in fat or sugar.
2. Pay Attention to Total Fat and Saturated Fat:
When checking the label of a food, always check the line
that reads "total fat." Most experts believe you
should get no more than 25 percent of total daily calories
from fat. For someone who weighs 160 pounds, that would
be about 72 grams a day. So before purchasing any food,
check the total fat to see if that product fits into your
eating plan.
Right below the "total fat" line is "saturated
fat." Again, you want this number to be very low, since
this type of fat is linked to obesity and heart disease.
No more than 10 percent of your calories should come from
saturated fats. For the average person, this is between
7-10 grams a day.
3. Figure Out the Percentage of Calories from
Fat:
In addition to listing the ingredients, labels give you
the information you need to determine the percentage of
calories from fat in a specific food product. Knowing this
is actually far more important than simply knowing the number
of grams of fat in the food product. Just as you want less
than 25 percent of your total daily calories to be from
fat, you also want to try to eat foods that get less than
25 percent of their total calories from fat. Because a food
product has a low number of fat grams, it is not necessarily
a low-fat, healthy food.
Take, for example, a reduced-fat whipping cream. Many
people assume that since this product only has 1.5 grams
of fat per serving that it is a healthy dessert topping
(often justifying double or triple the amount on their dessert).
However, this product contains actually 45 percent fat.
On the other hand, a common nutrition bar has 5 grams of
fat per serving. Many dieters would not touch this product
for fear of so much fat, when, in actuality, this product
contains only 12 percent fat.
How can a food that only has 1.5 grams of fat per serving
have a higher percentage of fat calories than a product
that contains 5 grams of fat. It is quite simple: The whipped
topping only contains 30 calories per serving whereas the
nutrition bar contains 380. The nutrition bar is packed
with protein and carbohydrates, giving the product a lot
more nutritious food value and more calories. Since the
whipped topping only contains 30 calories, it has very little
nutritional value and quite a bit of fat relative to the
total volume of food and calories. When checking labels,
be sure to figure out the percentage of fat calories in
addition to the number of fat grams.
To determine the percentage of calories from fat of a
food product, look for two important numbers: calories per
serving and total grams of fat per serving. Since you want
to know what percentage of the total calories are fat calories,
you must first convert the grams of fat into calories. Remember,
there are 9 calories per gram of fat.
To calculate the fat percentage of the food:
- Multiply the number of grams of fat by the number 9
(9 calories per gram of fat).
- Divide this number by the total calories per serving.
- The result is the percentage of fat calories (should
be less than 25).
