The Wrath of Cola

1. Study Links Cola to Bone Loss in Women

Regular consumption of carbonated cola drinks may increase risk for low bone mineral density (BMD) in women, according to the results of the Framingham Osteoporosis Study reported in the October issue of the American Journal of Clinical Nutrition.

2. Cola Drinks May Boost Blood Pressure

Women who drink lots of coffee can relax. But those who drink lots of cola may have a problem: high blood pressure.

High blood pressure isn't good. It's linked to heart disease and stroke. There's been a lot of worry that everyday coffee drinkers may be at increased risk of high blood pressure.

3. Cola, not coffee, increases risk of hypertension in women

Winkelmayer and colleagues explain that there is much "clinical lore" about the possible association between caffeine intake and the risk of hypertension. Any long-term effect of caffeine intake on the risk of developing hypertension would be of substantial public-health importance, given the widespread consumption of beverages containing caffeine, they note.

Although many short-term studies have shown that consumption of caffeine acutely increases blood pressure, this effect seems to be attenuated over time.
