Increasingly, people are aware of the dangers of 鈥渢oo much sugar鈥� in the diet. Consuming excess sugar can lead to a condition called , which is characterized by high blood pressure, high blood sugar, unhealthy cholesterol levels, and . Excess sugar also contributes to widespread inflammation and even leads to a higher risk of .

Excess sugar intake can be bad for your brain, too. Studies have found that high sugar intake has a negative effect on , and it has also been implicated in and in children and adolescents.

But what does 鈥渢oo much sugar鈥� look like? On the one hand, we have the well-known 鈥減roblem foods鈥� like sugar-sweetened sodas, candy, and baked treats. On the other hand, we have the naturally occurring sugars in some whole foods (like plain yogurt, milk, or fruit) that are part of a healthy diet.

Between those lurk the less well known hidden sugars that are so common in the average person鈥檚 diet.

Sugar鈥檚 hiding places

You might be surprised where added and hidden sugars can be found in the foods we eat every day. For example, a tablespoon of one popular brand of has 4 grams of sugar, and most people add about 3 tablespoons of ketchup to their burgers. That 12 grams of sugar from the ketchup alone is more sugar than you鈥檇 find in a serving of two store-bought , which contains only 9 grams of sugar! And a store-bought would seem like a healthy choice at only 60 calories in a single 1-cup (8 ounce) serving 鈥� but that single serving size still contains 11 grams of natural sugar, even though the label doesn鈥檛 list any added sugar.

A completed by the Department of Health and Human Services (HHS) noted that American adults consume 13.4% of their calories from hidden sugars, and in children, this figure is a whopping 17%. The main sources of the hidden sugars in the typical U.S. diet were snacks and sweets (31%), added sugars in beverages (47%), and soda (25%). Of course, few people would be surprised that soda is high in sugar.

What the experts say about hidden sugar

Until now, we clinicians have given dietary advice based on the recently revised , which simply reminds us to select foods and beverages with less saturated fat, sodium, and added sugars, without going into much detail. However, a in JAMA has summarized all the current guidelines for sugar intake (I鈥檝e listed them in the table below). These recommendations offer specific advice on sugar consumption and, unlike prior guidelines, they address added and hidden sugars in food 鈥� a welcome and important change.

Pay attention to these hidden sources of sugar

Consider these common 鈥渟ugar traps.鈥�

• Specialty coffees. Take, for example, a new Starbucks coffee drink, the . At 340 calories, a 鈥済rande鈥� (16-ounce) serving might seem like a relatively harmless once-in-a-while dessert-like treat. In fact, you might even guess that it鈥檚 on the healthier side because it contains honey, one of the 鈥渓ess demonized鈥� sugars. Look a little more closely, though, and you鈥檒l see it contains 45 grams of sugar! That鈥檚 180 calories of sugar. This single not-very-nutritious beverage takes you over your daily sugar limit.
• Honey. Let鈥檚 look a little more closely at honey as well. One study in the聽Journal of the American College of Nutrition聽found that honey 聽(a prebiotic that feeds gut flora) as well as small amounts of proteins, enzymes, amino acids, minerals, trace elements, vitamins, aroma compounds, and polyphenols. So one may argue, therefore, that honey is a healthy ingredient. However, your body breaks down honey 鈥� even raw, organic honey 鈥� as glucose and fructose. Just like plain old table sugar.
• Fruit juices. Basically, fruit juice is devoid of the healthy fiber you鈥檇 get from eating the fruit itself and instead concentrates the sugars. A single 8-ounce (1 cup) serving of contains only 110 calories and 0 grams of fat, but 22 grams of sugar! Those 22 grams of sugar are 88 calories 鈥� that is, more than half the calories in your morning glass of juice. And if you鈥檙e a woman, that鈥檚 nearly your entire sugar-calorie 鈥渁llowance鈥� for the day using the guidelines from the American Heart Association above. To think of it another way, that鈥檚 the equivalent of 5 陆 teaspoons of sugar. You probably wouldn鈥檛 add that much sugar to your morning coffee or tea.
• 鈥淎KA鈥� sugars. To be an astute label reader, you need to know that sugar can go by many names. For example, sugar can be also known as: agave nectar, barley malt, dextrose, rice syrup, isomalt, or high fructose corn sugar.

Know the sugar content of your food

A healthy diet is rich in fresh fruits and vegetables, healthy proteins (grass-fed meats, fish, poultry, and beans), a variety of whole grains, and healthy oils. Many of these foods include naturally occurring sugars and therefore are part of a healthy diet. But to truly eat well, you need to be on the lookout for hidden and added sugars. We also use guidelines for a healthy diet, for example, such as whole grains with an understanding that certain individuals may have food sensitivities, while others prefer to omit certain foods from their diet for various personal and or scientific reasons.

In future blogs, we will look more closely at sugar in the diet.
