Added Sugars

Also known as Free sugars, Added sugar

Added sugars are sugars and syrups added to foods and drinks during processing or preparation, unlike the natural sugars in fruit and milk. They add calories with little nutrition and are linked to weight gain, tooth decay, and heart disease. The Dietary Guidelines advise keeping added sugars to less than 10 percent of daily calories, and the American Heart Association suggests tighter limits of about 25 g/day for women and 36 g/day for men.

Why it matters

What it does in your body

  • Provide quick energy but no essential nutrients
  • Improve taste and texture in processed foods
  • Act as a preservative in some foods
  • Contribute empty calories that displace nutrient-dense foods

By age, sex, and life stage

How much you need

This is a limit, not a requirement. The Dietary Guidelines for Americans advise keeping added sugars to less than 10 percent of daily calories starting at age 2, and avoiding added sugars entirely before age 2. The American Heart Association recommends stricter limits of about 25 g/day (6 teaspoons) for women and 36 g/day (9 teaspoons) for men.

What moves the number

What changes your needs

Sugary drinks

Sodas, sweetened teas, energy drinks, and juices are the single largest source of added sugars.

Total calorie needs

The 10 percent limit is a share of calories, so gram amounts are lower for smaller diets.

Age

Children under 2 should avoid added sugars entirely during a key developmental window.

Hidden sources

Sauces, breads, flavored yogurts, and cereals can add sugar even when foods do not taste very sweet.

Running low

Signs you might not get enough

Not applicable; added sugars are not an essential nutrient

Most at risk: There is no deficiency state. The body has no requirement for added sugars.

Too much

Can you get too much?

Weight gain and obesityTooth decayHigher triglycerides and heart disease riskIncreased risk of type 2 diabetesFatty liver with heavy intake

Most Americans exceed the limit, largely from sugary drinks. Cutting back on sweetened beverages is the highest-impact single change.

Where to get it

Best food sources

Regular soda, 12 ozabout 39 g
Sweetened coffee drink, 16 ozabout 30 to 40 g
Candy bar, 1 standardabout 24 g
Flavored yogurt, 1 cupabout 17 g
Sweetened breakfast cereal, 1 cupabout 12 g
Ketchup, 1 tbspabout 4 g

The bottom line

Keep added sugars under 10 percent of calories, and ideally near 25 to 36 g/day. Start by cutting sugary drinks and reading labels for hidden sugars.
