“What Soft Drinks are Doing to Your Body” by Dr. Maoshing Ni is a frightening look at the damaging health effects of drinking soda. Research has shown that drinking large amounts of soft drinks has been linked to diabetes, obesity, heart disease, tooth decay, and nutritional depletion.
Not only does the high level of sugars in soft drinks end up being stored in the body as fat, but the raised insulin level causes the immune system to falter. Turning to diet sodas doesn’t seem to be the answer, as many artificial sweeteners have been found to be carcinogenic.
This article is a really fascinating read and gives ample justification for giving up the soda and switching to water, tea, or juice.
