How to tell if food has high-fructose corn syrup?

4 min read

Over 80% of processed foods in the U.S. contain some form of added sweetener. Knowing how to tell if food has high-fructose corn syrup (HFCS) is essential for anyone aiming to reduce their sugar intake and make more informed dietary choices. While HFCS is a common ingredient, it's not always obvious, and reading labels carefully is the only definitive way to know for sure.

Quick Summary

A guide to identifying high-fructose corn syrup (HFCS) by examining ingredient lists. Learn to spot the primary indicator, understand ingredient order, and recognize other related sweeteners. Gain insights into which food products most often contain this corn-derived additive.

Key Points

  • Check the Ingredients List: Always read the ingredients list first, as HFCS must be declared by name.

  • Prioritize Whole Foods: The most effective way to avoid all added sweeteners is to consume more fresh, unprocessed foods and fewer packaged products.

  • Spot Other Sweetener Names: Be aware of alternative names for corn-based sweeteners like corn syrup, maize syrup, and dextrose.

  • Scrutinize Ingredient Order: The higher up "high-fructose corn syrup" is on the list, the more of it the product contains.

  • Use the "Added Sugars" Line: The Nutrition Facts panel includes an "Includes Added Sugars" line to help you track total added sugar intake, not just from HFCS.

  • Mind Hidden Sources: Many items, including condiments, breads, and cereals, can contain HFCS, even if they don't taste overly sweet.

The Golden Rule: Read the Ingredients List

The most effective and straightforward method for determining whether a product contains high-fructose corn syrup (HFCS) is to read the ingredients list. By law, food manufacturers must list all ingredients in descending order of predominance by weight. This means if "high-fructose corn syrup" is among the first few ingredients, it is a primary component of that product. Conversely, if it appears near the end of the list, it is present in smaller quantities. The key is to avoid products where any form of added sugar, including HFCS, is high up on the ingredient list.

Look for the Explicit Name

The most obvious way to find HFCS is to look for the exact phrase on the ingredient label. The U.S. Food and Drug Administration (FDA) requires manufacturers to label it clearly, rejecting attempts by the Corn Refiners Association to change its name to "corn sugar" to avoid consumer confusion. A food product that includes this on the label contains the sweetener.

Spotting Other Names for Corn-Derived Sweeteners

HFCS is not the only corn-based sweetener to be aware of. Many processed foods contain various corn-derived sweeteners that may have different properties but still contribute to your overall sugar intake. By becoming familiar with these alternative names, you can be more vigilant in your food choices.

  • Corn syrup: Different from HFCS, corn syrup is a family of ingredients made up of only glucose. While it is not HFCS, it is still an added sugar derived from corn.
  • Corn syrup solids: This is a dehydrated form of corn syrup.
  • Maize syrup: 'Maize' is another word for corn, so this is another corn-derived sweetener.
  • Dextrose: A simple sugar (glucose) often derived from corn.
  • Maltodextrin: A polysaccharide used as a food additive, also derived from corn.

The Nutrition Facts Panel: A Broader Perspective

While the ingredients list is crucial for identifying the presence of HFCS, the Nutrition Facts panel provides a broader picture of a product's overall sugar content. Under the "Total Sugars" line, you will now see a line item for "Includes Added Sugars". This was mandated by the FDA to help consumers better understand how much sugar has been added during processing.

What to look for on the Nutrition Facts panel:

  1. "Includes Added Sugars" Line: Check the grams and the percentage of the Daily Value (% DV) next to this line. A high percentage indicates a significant amount of added sugar from all sources, including HFCS and other sweeteners.
  2. Compare Products: Use this panel to compare similar products. For instance, comparing the "Added Sugars" line on two different ketchup brands can help you choose the one with less added sweetener.

Examples of HFCS in Your Pantry

HFCS can be found in a surprising variety of everyday processed foods, even those that don't taste explicitly sweet.

Common HFCS culprits include:

  • Condiments: Ketchup, barbecue sauce, salad dressings.
  • Beverages: Sodas, sweetened juices, and sports drinks.
  • Baked Goods: Commercial breads, crackers, and pastries.
  • Cereals and Granola Bars: Many popular breakfast foods and so-called "healthy" snack bars contain HFCS.
  • Dairy Products: Flavored yogurts and some ice creams.
  • Canned and Jarred Foods: Canned fruits, pre-made sauces, and some jams.

Understanding the Product Type

Beyond label reading, being aware of what types of food are typically processed can serve as a shortcut for a more mindful shopping experience. Ultra-processed products, in particular, are the most likely to contain HFCS and other artificial additives. By focusing on a diet that emphasizes whole, unprocessed foods like fresh fruits, vegetables, and lean proteins, you can significantly reduce your exposure to hidden added sugars.

A Comparison of Common Sweeteners and Sources

Feature High-Fructose Corn Syrup (HFCS) Table Sugar (Sucrose) Raw Honey Agave Nectar
Source Corn starch, processed enzymatically Sugar cane or sugar beets Nectar collected by bees Agave plant sap
Fructose/Glucose Ratio Typically 42% or 55% fructose 50% fructose / 50% glucose Approx. 49% fructose / 43% glucose Up to 90% fructose (depends on processing)
Processing Highly processed, liquid form Processed, granulated crystals Minimally processed (raw), more vitamins Processed, liquid sweetener
Primary Uses Soft drinks, processed snacks, condiments Baking, home use, general sweetening Teas, spreads, natural sweetening Sweetening drinks, vegan alternative

Conclusion

Becoming an expert at spotting HFCS and other added sugars is a vital skill for anyone interested in managing their diet and health. By prioritizing the ingredients list, paying attention to the "Added Sugars" on the Nutrition Facts panel, and becoming aware of the types of foods that are typically processed, you can regain control of your food choices. Remember that whole, unprocessed foods are the best way to ensure you are not consuming hidden sweeteners. Start by checking your pantry and shopping carts for the biggest culprits like sugary drinks and common condiments, and gradually make more informed, healthier choices. For more on navigating food labels, the FDA provides a helpful resource on how to understand and use the Nutrition Facts label.

Frequently Asked Questions

High-fructose corn syrup (HFCS) is a liquid sweetener made from corn starch that has been processed to convert some of its glucose into fructose.

Yes, by law, manufacturers are required to list "high-fructose corn syrup" directly in the ingredients list if it is used in a product.

No, common corn syrup is composed primarily of glucose, while high-fructose corn syrup has been processed to increase its fructose content.

Manufacturers often use HFCS because it is a low-cost sweetener with a long shelf life, making it an economically attractive alternative to table sugar.

From a metabolic standpoint, some studies suggest that HFCS and regular table sugar (sucrose) have similar health effects when consumed in similar quantities. However, excessive consumption of any added sugar is linked to negative health outcomes.

Yes, HFCS is often used to balance flavor in a wide range of processed foods, including many savory condiments like ketchup, barbecue sauce, and salad dressings.

The best way to avoid HFCS is to read ingredient labels and reduce the consumption of processed foods, opting instead for whole, natural foods that have no added sweeteners.
