** THE PROS AND CONS OF FUNCTIONAL FOODS
* Functional foods have some health benefits, but functional foods are
not a substitute for a healthy lifestyle or any medications your
doctor may prescribe.
Peruse the shelves of your local supermarket and you’re sure to find a
proliferation of functional foods — products that contain ingredients
that purportedly offer health benefits, from lowering blood pressure
and cholesterol to boosting your body’s immune system. But do these
health products really provide the benefits their labels tout? Here we
look at three functional foods to let you know the pluses and minuses
of each.
* Functional Food 1: Activia Yogurt
Health claim: Helps naturally regulate your digestive system.
Functional food ingredient: Live cultures of the bacterium Bifidus
regularis.
Evidence for claim: Not much. All the research has been done by
Dannon, the makers of Activia. This research shows that, when eaten on
a daily basis, Activia decreases transit time (how long it takes for
food to pass through the digestive tract) by up to 40%. When food
moves slowly through your digestive tract, it can lead to constipation
and abdominal discomfort.
Pluses: Contains only 110 calories per 4-oz serving and is low in fat.
One 4-oz serving has 15% of the daily recommended amount of calcium.
Activia contains no artificial flavors or colors.
Minuses: Dannon recommends one serving (4 oz) a day, but more research
is needed to determine the minimum beneficial dose. More research is
also needed to definitely say this product has the intended effect.
However, it is safe to try Activia to see if it helps keep you
regular. Another minus: It contains added sugar.
* Functional Food 2: Nature Valley Healthy Heart Chewy Granola Bars
Health claim: Helps keep your heart healthy.
Functional food ingredient: 0.4 g of plant sterols.
Evidence for claim: Many studies show that eating 2 g of plant sterols
on a daily basis as part of a diet low in saturated fat and
cholesterol helps lower blood cholesterol levels.
Pluses: Contains oats and barley, which are whole grains. Contains 3 g
of fiber per serving. Low in saturated fat (only 0.5 g).
Minuses: To see a cholesterol-lowering effect, you will need to eat
five granola bars every day. That comes at a daily cost of about 750
calories. The granola bars are also high in sugar.
* Functional Food 3: Tropicana Pure Premium Essentials Orange Juice
With Fiber
Health claim: Helps your digestive system stay healthy and regular.
Functional food ingredient: Fibersol-2, a fiber derived from corn.
Evidence for claim: Research shows that fiber adds bulk to and softens
the stools, which may help prevent constipation.
Pluses: An 8-oz glass contains 3 g of fiber (as much as a medium sized
orange). Regular orange juice contains no fiber. Good source of
vitamin C, folate, and potassium.
Minuses: Why not just eat a medium- sized orange instead? It has just
as much fiber for half of the calories (60 vs. 120 calories). In
addition, the latest dietary guidelines recommend that most of your
fruit servings come from whole fruit.
