Sweetness or white poison?

June 3, 2015
Sugar, a very common food additive in the United States, and increasingly, in other countries, is being implicated in an increasing number of health conditions. This article discusses new research relating sugar to the stress response, diabetes, caries, and more.

We are finding that the consumption of sugar is not so sweet! Sugar comes in many forms, including high-fructose corn syrup, fructose, fruit juice concentrates, honey, sugar granules, syrup, corn syrup, sucrose, and dextrose. A recent article discussed how the National Caries Program was not successful in advancing a scientific understanding of how to restrict sugar consumption to prevent tooth decay. (1) The National Caries Program was a product of the (then) National Institute of Dental Research (NIDR). In the late 1960s, the National Institutes of Health (NIH) stated that decreasing sugar ingestion was not practical for the public’s health, while theoretically a sound premise. This article will delve into the dangers of sugar ingestions.

The average American consumes 150–170 pounds of sugar each year. (2) It is no wonder obesity in the USA is skyrocketing. 150–170 pounds of sugar each year is comparable to ingesting .25 to .5 pounds of sugar, or 30–60 teaspoons, in a 24-hour period. This calculator can help you figure how much sugar you consume from beverages. Some scientists have found that sugar is a poison to our systems, and too much causes immune system impairment, a drop in white blood cell count, as well as heart disease, obesity, and diabetes. However, one 2010 study published in Critical Reviews in Food Science and Nutrition found that that the existing evidence did not support a single quantitative sugar guideline covering all health issues. (3) The same study found that mixtures of sugar amount and frequency, fluoride exposure, and food tackiness were more dependable prognosticators of caries risk than the amount of sugar alone. Critical Reviews in Food Science and Nutrition is a highly respected journal, with an impact factor of 5.5.

This issue is not just a concern for the United States. A 2015 study of European adults determined that the ingestion of soft drinks, sweetened milk beverages, and energy from total sweet beverages was related to higher type 2 diabetes risk by themselves, even without the influence of body fat. (4) Water or unsweetened tea and coffee appear to be appropriate substitutions to sugar-sweetened beverages.

The study found that compared with people who drink only one sugar-sweetened drink per day, those who drink water, coffee, or tea as an alternative are at 14% lower risk of developing type 2 diabetes. (4) Surprisingly, drinking fruit juice and sweetened tea or coffee was not associated with diabetes. (4)

A brand-new study found that ingesting sugar­-sweetened drinks can suppress cortisol and stress responses in the brain, but diet beverages sweetened with aspartame do not have the same effect. (5) This is the first study to show that sugar’s stress-relieving properties can perhaps leading to over consumption and habituation, increasing the risks of sugar, such as obesity. These results help us to understand why some people are tempted to eat sugary comfort food when they feel stressed. (5)

Recent research illustrates that the risk of cardiovascular disease increases as the amount of added sugar consumed increases. (6) Even when young, healthy men and women ingested added sugar for, their risk factors for cardiovascular disease were considerably increased. (6) The risk factors for cardiovascular disease, specifically lipid profiles, were greater in men than in women and were independent of body weight gain. (6)

Many studies have shown that added sugar is bad for one’s health. Reducing all sugar consumption is desirable, especially high­fructose corn syrup. (7) In the American diet, 44% of the added sugar is sucrose, 42% is high­fructose corn syrup, and the remaining 14% includes honey, molasses, juice concentrates and agave. (7) The remaining 14% combine fructose and glucose, known as dextrose. Globally, high­fructose corn syrup is only about 8% of added sugar consumption. On a positive note, Burger King removed soft drinks from their kids’ menu, offering milk and 100% apple juice instead. Fast-food chains are trying to contribute to fight childhood obesity. (8)
