High-Fructose Corn Syrup vs Sugar: Which is Better?

High-fructose corn syrup (HFCS), also referred to as glucose-fructose syrup, is a sweetener derived from corn starch. It is frequently used as an alternative to sugar in food and beverage products. In contrast to the common ‘sugar’ (sucrose), a combination of glucose and fructose extracted from sugar cane or sugar beet, HFCS is produced by breaking down corn starch into glucose using enzymes. 

While both HFCS and sugar are forms of sweet-tasting, soluble carbohydrates, they differ in their composition and source. The use of HFCS and sugar has sparked debates and raised concerns due to its prevalence in processed foods, leading many to opt for alternatives in their diet. Are they both just as bad as each other? Let’s take a look.

Differences Between High-Fructose Corn Syrup And Sugar

Sugar finds its way into numerous food products. It comprises simple sugars, also known as monosaccharides, such as glucose, fructose, and galactose. The common type of sugar, sucrose, is derived from a combination of glucose and fructose and is typically extracted from sugar cane or sugar beet. Sugar serves other significant roles aside from sweetening in food technology, serving as a preservative, texture modifier, fermentation base, flavoring and coloring agent, and bulking agent. 

High-fructose corn syrup is an artificial sweetener produced from corn syrup. It exists as a liquid sweetener derived from corn. Initially, corn starch is broken down into individual molecules, resulting in corn syrup – a simple sugar composed entirely of glucose. Enzymes are introduced to convert a portion of this glucose into fructose. HFCS is predominantly used in processed foods, cereals, baked goods, and select beverages like soft drinks.

Taste and Culinary Uses

When it comes to sweetness, high fructose corn syrup and sugar have similar flavors; however, HFCS tends to be slightly sweeter. Researchers studying the relative sweetness of natural and artificial sweeteners found that HFCS is about 1.5 times as sweet as table sugar. Some individuals even seek out drinks like Mexican Coca-Cola, which uses sugar instead of HFCS, because they prefer its taste.

In terms of culinary applications, both HFCS and sugar play key roles. Sugar, considered the gold standard of sweet taste, provides a clean and pleasant sweetness that is noticeable from start to finish in desserts and baked goods. It is widely used in sauces, syrups, and beverages to enhance viscosity and create a thicker consistency. Aside from being a sweetener, HFCS acts as a fermentable sugar and humectant in various applications. In baked goods like breads, buns, rolls, and yeast-raised donuts, HFCS can ferment directly without requiring sugar inversion, making it a convenient option for these products.

Are High-Fructose Corn Syrup and Sugar Substitutes for Each Other?

Technically, yes, but it would result in a different textured product. Try 1 cup HFCS for every 1.5 cups of sugar for similar sweetness, and reduce the other liquid ingredients.

Nutritional Profile And Health Benefits

Table sugar (granulated sugar, sucrose) (2 tsp.)

• Calories: 30
• Total carbs: 8 g
• Sugars: 8 g
• GI: 65

High-fructose corn syrup (1 tsp.)

• Calories: 16
• Total carbs: 4 g
• Sugars: 4 g
• GI: 73+

High fructose corn syrup shares a similar taste and metabolic effect to table sugar. Although overconsumption of HFCS in sweetened drinks and processed foods can contribute to excessive calorie intake and weight gain, minimal consumption as part of a well-balanced, nutritious diet is considered safe by the regulatory authorities. 

Diet Suitability

Let’s start with high fructose corn syrup. While HFCS is vegan-friendly, it’s worth noting that most corn used in its production is genetically modified. Genetically modified corn is engineered to protect against pests and insects, sometimes using animal genes in the modification process. As a result, some individuals following a vegan lifestyle may consider GMO-derived HFCS not vegan.

In terms of diet considerations, high fructose corn syrup is not paleo-friendly or approved in Whole30 diets. Additionally, HFCS has a high glycemic index, meaning it can cause a rapid increase in blood sugar levels. For those aiming to avoid high glycemic sweeteners, such as sugar, honey, and agave nectar, it’s advisable to steer clear of HFCS as well.

Sugar, which is traditionally refined from cane or beet, also has its own set of considerations. While refined cane sugar is not vegan due to some processing involving bone char, sugar from sugar beet is fine. However, it is not classified as keto-friendly, paleo-friendly, or compliant with a Whole30 diet.

How to Store High-Fructose Corn Syrup and Sugar

For optimal storage, sugars are best kept at room temperature in an airtight container. It is recommended to handle and store sugars between 80° and 100°F. High fructose corn syrup can be stored in a cool, dry place away from direct sunlight, and make sure the lid is on tight. 

Price and Availability

Sugar is available for as low as 25 cents per pound. Although high fructose corn syrup can be found online for $12 per gallon, it is not commonly sold on Amazon and may require some searching on specialty websites.

Environmental Impact

The burning of sugarcane has a detrimental impact on the environment, mainly through the emission of various harmful substances that contribute to air pollution. These substances include nitrates, carbon compounds, and sulfates, which not only degrade air quality but also contribute to the issue of climate change. When sugarcane is burned, releasing these compounds reduces oxidization efficiency and increases ozone concentrations.

The environmental impact of high fructose corn syrup is also significant. The production of HFCS often relies on monocultures, which involve using pesticides to ensure crop survival. However, this pesticide use has harmful consequences, as it can deplete the nutrients in the soil, lead to erosion, and pollute both the soil and groundwater. Additionally, the hydrofluorocarbon refrigerants (HFCs) commonly used in cooling and refrigeration systems associated with HFCS production are considered potent greenhouse gases. Pound for pound, HFCs can trap thousands of times more heat than carbon dioxide (CO2), contributing to the rapid increase of greenhouse gas emissions.

High-Fructose Corn Syrup vs. Sugar: The Ultimate Verdict

I will never understand why high fructose corn syrup is used when real sugar tastes so much better! Maybe it is cheap and convenient for food manufacturing, but I prefer to steer clear of it and opt for more natural sugar instead. Thumbs down from me, HFCS!
