Despite knowing how bad they are for our health, most of us continue to drink sodas. Soft drinks are the beverage of choice for millions of people, second only to water. But sugary drinks increase the risk of diabetes and heart disease. A study that followed 40,000 men for two decades found that those who averaged one can of a sugary beverage per day had a 20% higher risk of having a heart attack or dying from a heart disease than men who rarely consumed sugary drinks. A related study of women found a similar correlation. 

Most people either forget or don’t realise how many extra calories they consume through what they drink. Drinking a single 330 ml can a day of sugary drinks translates to more than 1lb of weight gain every month. There is good evidence that cola beverages can increase the risk of kidney problems, more so than non-cola sodas. Researches clearly demonstrate that large quantities of cola result in enhanced kidney stone formation. If you’re wondering exactly how soft drinks cause kidney stones, it’s because of their acidity and radical mineral imbalance. Your body must buffer the acidity of soft drinks with calcium from your own bones. As this calcium is eliminated through your urine, it slowly forms kidney stones. Another problem with sodas is that they act as dehydrating diuretics. Both caffeine and sugar cause dehydration. Caffeine is a diuretic and causes an increase in urine volume. High concentration of sugar is drawing off water because your kidneys try to expel the excess sugar out of the blood. When you drink a caffeinated soda to quench your thirst, you will actually become thirstier.
