While we hear all the time that sugar is not healthy, many of us continue to eat it, and allow our kids to eat it -- then we wonder why there's an uptick of colds and flu in the household. An 1973 undisputed study reminds us how this happens.


The consumption of sugar is increasing rapidly. Parallel with the increase of sugar consumption is an increase in chronic disease, Diabetes, Heart Disease, Cancer, and more.

While sugar being bad for you isn't new news and the study referenced in this article isn’t new research, no other study has disputed it. This undisputed study from 1973, published in the American Journal of Clinical Nutrition, has not been disproven, and still holds true to this day. Yet many people don’t know it exists.

High Sugar Consumption And Flu Share The Same Season

The study claims to this day, that sugar is a depressant of the immune system. In other words, if you eat high amounts of sugar in your diet, you are more likely to get sick. Therefore, it is a fact that many who eat high amounts of processed food and fast foods that are high in sugar, are more likely to be susceptible to colds, flu, and infection.

We accept that colds and flu are imminent each winter, but many people don’t often make the connection that it is caused by their diet. In the U.S., from Halloween through to February, it is highly likely that many children are eating a lot of sugar. According to the study’s findings this type of eating brings down their immune function, leaving them vulnerable to disease.

Sugar Also Causes White Blood Cell Malfunction

White blood cells are the “fighter” cells that protect you from bacteria and viruses. The study also found that sugars reduce the “phagocytic capacity” of the white blood cells. Phagocytic capacity is a scientific term describing the inability of your white blood cells to kill viruses, bacteria and remove foreign matter from the blood. The study reported that the greatest suppression happened between one to two hours after sugar consumption and was significant even after five hours after feeding. “

Not surprisingly, the study confirmed that ingestion of starch, also known as complex carbohydrates, had no suppressing effect on the immune system. Starches are found in sweet and white potatoes, vegetables, grains, legumes, nuts and seeds. These foods are powerhouses of nutrition making them an essential part of your and maintaining your good health.

Another Study Confirms Sugar Depresses Immune Function

To confirm the findings that sugar is, in fact, a depressant of the immune system, there was a second study conducted by Ringsdorf, et al. This study gave their subjects twenty-four ounces of sugar (sucrose) sweetened cola. Results showed, the disease-fighting capacity of the white blood cell’s ability to fight disease (phagocytic index) was reduced by fifty percent.
