Another ingredient to be on the lookout for is saturated
fat. Many bars have moderate amounts of fat, (4-8 grams
per bar). The total fat grams, however, is not as important
as the type of fat used. Some bars derive their fat from
peanut butter, which is fine in small amounts. Unfortunately,
others use hydrogenated oils and tropical oils such as coconut
oil or palm kernel oil. These are the "bad fats"
that have been implicated in heart disease and cancer. Watch
out for those 40-30-30 bars - they are notorious for this.
There is nothing magical about the 40-30-30 ratios just
because a best-selling book says so. One popular brand of
40-30-30 bars lists soy protein as the first ingredient,
corn syrup as the second and fractionated palm kernel oil
as the third. These companies are really taking advantage
of the public's naivete by calling these "health food"
or "nutrition bars." If you think you're eating
some magical combination of nutrients, think again - what
you're really eating is empty sugar calories and saturated,
artery-clogging fat!
When choosing a bar you should also look at the total calories
and the carb to protein ratio. There are several different
types of bars available, including energy bars, protein
bars and meal replacement bars. The ratio of nutrients in
each type can vary greatly. Your best bet is to choose one
with a substantial amount of protein (30 grams of protein,
preferably whey, is good for a bar). A meal replacement
bar is usually around 300 calories with a ratio of one part
protein to two parts carbs. If you're on a fat reducing
program, then you may want to choose a protein bar with
the opposite ratio: Two parts protein to one part carbs.
Other bars are marketed as "energy bars" because
they are primarily carbohydrates.
An example of a meal replacement bar is the original Met-Rx
"Food bar." They contain 320 calories, 48
grams of carbs and 27 grams of protein (a pretty good ratio
for a meal replacement). But let's examine where the carbs
come from: On the ingredients list, Metamyosin (Met-Rx's
proprietary whey, milk and egg protein blend) is the first
ingredient. So far, so good. But look at the second ingredient:
Corn syrup (sugar!) What's the third ingredient? High fructose
corn syrup (read: more sugar!) So the second and third ingredients
are refined sugar. Not exactly diet food is it?
Protein bars such as "Pure
Protein" by Worldwide Nutrition are immensely popular
these days because so many people are on low carb or reduced
carb diets. The bad thing about the "Pure Protein"
bars is that most are coated with real chocolate (yes, the
same stuff a Hershey's bar is made of). Others are coated
with Yogurt (a slight improvement.) The good thing about
"Pure Protein" is that with 280 calories, 31 grams
of protein, 16 grams of carbs and 4 grams of fat, the calories
and ratios of nutrients are good for a fat loss program.
And the total carbs and sugars are low. Also, it's a convenient
way to get 31 grams of whey protein.
Power
bars are energy bars that were designed with endurance
athletes in mind. Power bars contain about 80% of the calories
from carbs, 20% from protein and minimal fat. An endurance
athlete's diet is very high in carbs, as much as 60% or
more of total calories. That makes the Power Bar a decent
energy food for endurance athletes in intense training.
Unfortunately, the Power Bar has the same problem as many
other bars - it's mostly sugar. Maltodextrin, an excellent
source of Complex carbohydrate, is the second ingredient,
but the first ingredient is - you guessed it - high fructose
corn syrup. You'll probably burn all those carbs up if you're
extremely active, but these are not the greatest for a fat
reducing program and they're skimpy on the protein. If you
need the carbs, why not just have a piece of fruit instead?
Some of the newest brands of MRP and protein bars have
gotten around the refined sugar and saturated fat problem
by using fake fats such as Salatrim and artificial sweeteners
such as Acesulfame Potassium. When most of the refined sugars
and saturated fats are removed, using fake fats and artificial
sweeteners is the only way left to make the bars palatable.
There is an ongoing debate about the safety of artificial
sweeteners and fake fats. The Center for Science in the
Public Interest rates Acesulfame Potassium as one of the
top ten worst food additives, because tests showed that
it caused cancer in animals. It is important to note however,
that these tests involved giving laboratory rats hundreds
of times the amount that humans would normally ingest in
a day.
Furthermore, the Food & Drug administration (FDA) categorizes
it as generally recognized as safe (GRAS), a classification
for all food additives that are considered harmless. The
American Dietetic Association (ADA) also approves of fake
fats and artificial sweeteners including Aspartame and Acesulfame
K. The ADA's position statement on "fake" fats
says "Fat replacers may offer a safe, feasible and
effective means to maintain the palatability of diets with
controlled amounts of fat and/or energy." The ADA's
position statement on artificial sweeteners says, "It
is the position of the ADA that consumers can safely enjoy
a range of nutritive and non-nutritive sweeteners when consumed
in moderation and within the context of a diet consistent
with the Dietary guidelines for Americans." Probably
the best advice is to just do like the ADA (and your mother)
told you and partake of all things, including artificial
sweeteners, in moderation.
The new Met-Rx
"Protein Plus" bar is one of the new breed
of bars that uses artificial sweeteners and fake fats. Let's
take a look at what's in them: The "Protein Plus"
bar contains 300 calories and only 15 grams of carbs. The
first ingredient is "Metamyosin" protein. With
32 grams, there's probably no easier way to get a whole
meal's worth of high quality complete protein when you're
in a hurry.
The second ingredient is a "faux" chocolate coating
that includes Maltitol, Salatrim, peanut butter and Acesulfame
Potassium. Maltitol is a "sugar alcohol" that
is used as a sweetener. It has half the caloric value of
sucrose because it is not completely absorbed by the body.
The FDA classifies it as GRAS. Salatrim is a reduced calorie
fat developed by Nabisco that has only 5 calories per gram
as opposed to 9 calories in conventional fats. Salatrim
is used in both solid and liquid forms in snacks, cookies,
dairy products, (and now protein bars).
The third ingredient is Glycerine, a crystalline, viscous
liquid formed when fat molecules split. It is half as sweet
as sugar and is used to keep baked goods, jelly beans and
marshmallows moist and to plasticize foods such as fudge,
chewing gum, gelatin, cheese, etc. Glycerine is GRAS. Additional
ingredients in the bar include peanut flour, polydextrose
(a bulking agent with only 1 calorie per gram), natural
flavors, malt barley syrup and peanut butter. Clocking in
with 8 grams of fat, or about 24% of the total calories,
the Protein Plus bar is not exactly low fat, but the fat
is not saturated and the total calories in the bar are not
excessive.
Source One bars, also by Met-Rx, are similar, with the
protein blend as the first ingredient, Salatrim the second,
and cocoa the third. The only difference is the Source One
Bar has only 190 calories with 30 grams of carbs and 15
grams of protein. That makes it a decent snack for people
on a reduced calorie diet.
All things considered, if you are concerned with staying
lean and muscular, then you're better off with bars that
use artificial sweeteners and fat replacers than ones loaded
with corn sweetener (refined sugar) and palm kernel oil
(saturated fat). No bars are "excellent" nutrition-wise,
but some are definitely better than others. My advice is
to read the labels carefully and choose one that is low
in calories and refined sugars, uses no saturated fats and
has a good protein to carb ratio.
Always stick with whole foods whenever possible and make
the powdered MRP shakes your second choice. Don't make it
a habit to eat bars regularly - use them for convenience
only. But remember, you have to eat something every 3 or
4 hours for a muscle-building or fat reducing diet to work,
so if you have no other alternative, a bar might be the
only way to get your fill of protein in a pinch.
