A new American Heart Association scientific statement
provides specific guidance on limiting the consumption of added sugars and
provides information about the relationship between excess sugar intake and
metabolic abnormalities, adverse health conditions and shortfalls in essential
nutrients. The statement, published in Circulation: Journal of the American
Heart Association, for the first time, provides the association's
recommendations on specific levels and limits on the consumption of added
sugars.
Study highlights:
High intake of added sugars is implicated in numerous poor
health conditions, including obesity, high blood pressure and other risk
factors for heart disease and stroke.
Added sugars and solid fats in food, as well as alcoholic
beverages are categorized as "discretionary calories" and should be eaten
sparingly.
Most American women should consume no more than 100 calories
of added sugars per day; most men, no more than 150 calories. (Prior studies
have found that the average American is ingesting 355 calories daily from added
sugars).
Soft drinks and other sugar-sweetened beverages are the
number one source of added sugars in the American diet. (Soda, for example,
contains about 130 calories in just a 12-ounce can).
Added sugars are sugars and syrups added to foods during
processing or preparation and sugars and syrups added at the table. High intake
of added sugars, as opposed to naturally occurring sugars, is implicated in the
rise in obesity. It's also associated with increased risks for high blood
pressure, high triglyceride levels, other risk factors for heart disease and
stroke, and inflammation (a marker for heart disease), according to the
statement's lead author Rachel K. Johnson, Ph.D., M.P.H., R.D., associate
provost and professor of nutrition at the University of Vermont in Burlington.
"Sugar has no nutritional value other than to provide calories,"
Johnson said. "Consuming foods and beverages with excessive amounts of added
sugars displaces more nutritious foods and beverages for many people."
The statement says that most women should consume no more
than 100 calories (about 25 grams) of added sugars per day. Most men should
consume no more than 150 calories (about 37.5 grams) each day. That's about six
teaspoons of added sugar a day for women and nine for men.
In contrast, the statement cites a report from the 2001-04
National Health and Nutrition Examination Survey that showed the average intake
of added sugars for all Americans was 22.2 teaspoons per day (355 calories).
Soft drinks and other sugar-sweetened beverages are the
number one source of added sugars in Americans' diet, according to the
statement. "One 12-ounce can of regular soda contains about 130 calories and
eight teaspoons of sugar," Johnson said.
The American Heart Association recommends a dietary pattern
that is rich in fruit, vegetables, low-fat dairy products, high-fiber whole
grains, lean meat, poultry and fish.
"This new statement expands on earlier recommendations and
gives consumers more detailed guidance by recommending a specific upper limit
on added-sugars intake," Johnson said.
In addition, the statement recommends that no more than half
of a person's daily discretionary calorie allowance should come from added
sugars.
Discretionary calories refer to the number of calories "left
over" after a person eats the recommended types and amounts of foods to meet
nutrient requirements, such as fruit, vegetables, low-fat dairy products,
high-fiber whole grains, lean meat, poultry and fish. Added sugars, alcoholic
beverages and solid fats - including saturated fat and trans fat - are
typically considered discretionary calories that are to be included after
individual daily nutrient requirements are met.
"It is important to remember that people's discretionary
calorie ‘budgets' can vary, depending on their activity level and energy
needs," Johnson said. "So, if you can't live with the recommended limits on
your added sugars, you'll have to move more."
For example, a moderately active 51-55 year-old woman who
eats 1,800 calories per day and maintains her weight would have about 195
discretionary calories per day and only about 100 calories, or half that
amount, should come from added sugars. In comparison, if that same woman, still
maintaining her weight, was more physically active and burned 2,200 calories a
day, she could consume 2,200 calories a day, and would have a larger
discretionary ‘budget' of about 290 calories. About half of that amount, or 145
calories, could come from added sugars.
To ensure proper nutrient intake in the diet and to limit
excess calories, Johnson said people should be sure foods high in added sugars
are not taking the place of foods with essential nutrients or increasing their
total calorie intake.
She recommended that people use their added sugars
"allotment" as a vehicle to enhance the flavor of otherwise nutrient-rich
foods. For example, choosing a nutrient-rich dairy product, such as a flavored
yogurt or a sugar-sweetened whole-grain breakfast cereal, would be a better
choice than a nutrient-void candy.
