Hidden Sugars in your Diet

Excess sugar consumption is strongly associated with weight gain, insulin resistance, and increased risk of type 2 diabetes and cardiovascular disease. Importantly, these risks persist even when total calorie intake appears reasonable, highlighting that where calories come from matters as much as how many are consumed. Large human cohort studies ¹ demonstrate that diets high in added sugars are linked to higher triglyceride levels, lower HDL cholesterol “(the good cholesterol”), and greater cardiometabolic risk. 

Even foods perceived as “healthy” or “savory” can contain surprisingly high sugar levels. Many everyday foods, such as condiments, sauces, dressings, packaged snacks, and even bread, often contain hidden sugars. For example, some commercial salad dressings contain 6–10 grams of sugar per serving, often equal to or exceeding the sugar content of desserts. To make this worse, individuals don’t always use just the suggested serving size. This can quickly turn a healthy salad into a high-calorie, sugar ridden meal.  Common culprits include:

• Salad dressings (especially fat-free or low-fat varieties)

• Barbecue sauces

• Ketchup and tomato sauces

• Marinades

• Flavored yogurts

• Protein bars and meal replacements

One of the biggest challenges consumers face is that sugar rarely appears simply as “sugar” on ingredient lists. Instead, manufacturers use multiple alternative names, making it harder to recognize total sugar exposure. Products containing multiple sugar sources often appear healthier than they are because each sugar appears lower on the ingredient list, masking the total sugar load.

Common hidden sugar names include:

• Corn syrup

• High-fructose corn syrup

• Sucrose

• Maltose

• Fructose

• Molasses

• Honey

• Malt syrup

• Maltodextrin

• Invert sugar

• Malt extract

According to research ², food manufacturers often use terms like “no added sugar” or “reduced sugar” that can be misleading if calorie reductions aren’t meaningful, confusing consumers about the actual sugar content. They also list many sugar forms or sweeteners under different names (e.g., syrups or scientific‑sounding sugars) so that total sugar isn’t obvious at a glance, and consumers may misinterpret nutrition claims, leading to hidden added sugars on products.

Sugars consumed in liquid or semi-liquid forms, such as sauces and dressings, are metabolized rapidly and provide little satiety, meaning they don’t help you feel full. It has been shown that liquid sugars lead to weaker appetite suppression than solid foods, increasing the likelihood of overeating later. Research ³ shows that carbohydrates consumed in liquid form (e.g., sugary beverages) generally lead to weaker feelings of fullness compared with solid carbohydrates, which can contribute to higher overall energy intake later.

Frequent exposure to hidden sugars causes repeated spikes in blood glucose and insulin. Over time, this can contribute to insulin resistance, even in individuals with normal body weight. Sugar-sweetened beverages (SSB), which are now the primary source of added sugars in the U.S. diet, are composed of energy-containing sweeteners such as sucrose, high-fructose corn syrup, or fruit juice concentrates. 

Prospective human studies ⁴ demonstrate that higher intake of added sugars is associated with reduced insulin sensitivity and an increased risk of metabolic syndrome. Higher levels of SSB intake could be a marker of an overall unhealthy diet as they tend to cluster with factors such as higher intakes of saturated and trans fat and lower intake of fiber. 

A study ⁵ analyzing U.S. dietary survey data found that regular use of sugar information on nutrition panels (i.e., looking at sugar content on product labels) was associated with a significantly lower dietary added sugar density, suggesting that label readers had lower added sugar consumption. It shows that individuals who actively monitor ingredient quality reduce added sugar intake significantly over time. Fortunately, reducing hidden sugars doesn’t require eliminating flavor or convenience. Evidence-based strategies include:

• Reading ingredient lists carefully, not just nutrition labels

• Choosing products with one or no added sugar sources

• Opting for homemade dressings and sauces when possible

• Selecting unsweetened versions of condiments

• Tracking ingredients, not just macros, using food-logging apps

Even when you’re diligent about tracking your macros, hidden sugars in everyday products like salad dressings, condiments, and sauces can easily sneak into your diet. These sugars can significantly contribute to your overall daily intake, even if you're mindful of other food choices. The root cause of this issue is the lack of clear labeling and manufacturers' use of hidden-sugar names. With so many disguised forms of sugar, such as high-fructose corn syrup and molasses, it's difficult to stay fully informed without extra effort.
