Avoid Sugar to Improve Immune Function!


Diets high in sugar have been linked to health problems including diabetes, hypoglycemia, asthma, candida infections, headaches, intestinal gas, inflammatory bowel disease, chronic constipation, obesity and tooth decay.

Eating sugar affects cancer as well. Elevated insulin levels slow the release of growth hormones, which in turn reduces white blood cell production and promotes tumor growth. Insulin, the hormone that lowers blood glucose, in excess will send a message to our cells to grow! This is great for healthy cells, but not so great for the cancer cells. One of the goals in our food choices should be to avoid the dramatic spikes in blood sugar, with the correlating spike in insulin. Referring to glycemic index information can assist in making informed, lower GI food choices. (http://www.nutritiondata.com/topics/glycemic-index)

High sugar diets also increase production of secondary bile acids. These carcinogenic compounds contribute to a toxic GI environment and have been linked to colorectal cancer. Reducing sugar in our diets is a very positive step towards fighting cancer.

Let’s take a look at what sugar does to our immune system. Neutrophils are a type of white blood cell that phagocytize (eats) any viruses, bacteria, cancer etc. that is present in your body. In order to swallow these invaders efficiently, these white blood cells need vitamin C to be inside the cell. To the white blood cells, the vitamin C and sugar look similar in structure. If there’s a lot of sugar in your system, it will compete with the vitamin C for entry into the white blood cell. The more glucose that goes into the cell, the less vitamin C that enters, so the phagocytic ability of the cell weakens. The average white blood cell can gobble up about 14 germs in an hour. When the body is exposed to 100g of sugar (about 3.5 ounces), the number of germs per hour falls to 1.4 and stays that way for two hours. Tackling sugar overload is something that is important to boost the immune system. According the U.S. Department of Agriculture, a safe amount of sugar is about 40g (1.5 ounces) per day. If you can reduce your intake, you can dramatically improve your health and improve the way your immune system functions.
