In the study, participants of the study consumed 100 g of either fructose, glucose, sucrose, orange juice, or honey after fasting overnight. Before and after the consumption of the various kinds of sugar, the researchers collected blood samples from the participants. Then, the blood samples were exposed to Staphylococcus bacteria strain.
Based on the results, the presence in the bloodstream of the any of the sugar examined caused a significant reduction in the immune response. In all cases, the ability of the white blood cells to surround and combat the bacteria dropped by approximately 50 percent.
Research has also revealed that viral replication in bugs, such as the influenza virus, relies on the amount of glucose available in the bloodstream. This means that bacteria and viruses feed on sugar. Higher levels of sugar in the blood can increase the survival rate of bacteria and viruses.
Moreover, the amount of sugar in two cans of soda has an almost immediate adverse effect on immunity, starting 30 minutes or earlier after consumption. These adverse effects can go on suppressing immunity for five hours or longer. Other factors, such as current health status, stress levels, and the amount of sleep a person has been getting, may worsen the adverse effects of high blood sugar levels on the immune system.
High blood sugar level in the body also increases one’s risk of developing cancer. Similar to bacteria and viruses, cancer cells also feed on sugar. Moreover, the increased inflammation stimulated by high consumption of sugary food and beverages and increased blood sugar levels create a more favorable environment for cancerous tumors to grow.

It is important to know the difference between added sugars and naturally-occurring sugars. Naturally-occurring sugars from fruits and vegetables are safe to consume, while added sugars are not. Sugar consumption in the U.S. is extremely high. The average sugar consumption of the average American adult in 2012 was 77 g per day, which is way too over the limit of 37.5 g for men and 25 g for women. Because of the adverse effects of sugar consumption on health, people are encouraged to limit their sugar intake. Here are some steps in minimizing sugar consumption:
