8 Reasons High-Fructose Corn Syrup Is Bad for You

High fructose corn syrup serves as one of the most damaging food items available. You will not only see a decrease in normal healthy bodily functions, but an increase in the risks for several harmful diseases and illnesses. Here are 8 reasons HFCS is bad for you.

Reason #1: Increase in Bad (LDL) Cholesterol and Triglycerides

Typically, over-consuming sugar will result in metabolic hindrances. High fructose corn syrup causes a major increase in insulin and leptin resistance, two key factors that help metabolize food into energy. Your body will encounter increased levels of bad cholesterol because the metabolized sugar turns to fat, in turn elevating triglyceride levels, also known as fat storages.

Reason #2: Risk of Heart Attack and Heart Disease

Consuming large quantities of HFCS will lead to worsened cholesterol levels in that the bad cholesterol will continue to heighten and the good will fall. As an outcome, arteries get damaged or blocked and the natural flow of blood to and away from the heart decreases. This diminishing cycle damages the muscles within the heart and forces them to work much harder.

Oxygen circulation becomes limited, and you will not have the ability to perform lengthy exercise or physical activity without losing breath and muscle energy.

Reason #3: Anemia Variations

Since high fructose corn syrup does not contain any sort of nutrients other than sugary carbohydrates, the sweetener depletes storages of other valuable vitamins and minerals in order to fully digest and metabolize within your body.

Reason #4: Poor Immunity

Tied in with the third negative effect, high fructose corn syrup also decreases the levels of helpful bacteria fighting enzymes within your body. These valuable and rare hormones work to protect you against several forms of simple and more serious illnesses.

Reason #5: Empty Calories

High fructose corn syrup will provide extra calories to your diet with no added benefit. Think of the altered sugar as strictly a form of calories and nothing more. Although food sources packed with HFCS leave you feeling full some of the time, that fullness will not give your body any nutrients at all. This poses a problem to many individuals looking for nutritionally dense foods, especially when counting calories.

Reason #6: Increases the Risk of Diabetes

Many sugars including high fructose corn syrup cause large spikes in the secretion of insulin. The overworking pancreas often leads to some form of damage, regularly causing diabetes in both males and females.

Reason #7: Tooth Damage

Sugars like HFCS that get stuck between teeth or remain on their enamel surfaces rot and deteriorate their structure. In most cases, cavities directly happen as a result of the overconsumption of sugary foods and the lack of proper teeth cleaning. The risk of getting tooth damage, especially cavities, greatly increases through eating a diet containing high fructose corn syrup and other sweeteners.

Reason #8: A Combination Leading to Obesity

As mentioned before, high fructose corn syrup does not trigger your body to produce either insulin or leptin. These two crucial and naturally occurring substances in the body help regulate metabolism and appetite or hunger control.

The combination of directly storing HFCS as fat, plus not knowing when to stop eating, directly contributes to the likeliness of obesity in people across the world.

    Could you share the research literature behind these 8 things? I am working on an incentive and education structure to get people to be more attentive to what’s in their food (and what they put in their bodies), and would love to reference some of these studies!

    Many thanks,
