Do you reach for a Red Bull for an afternoon pick-me-up? After reading this (or drinking that), you may have a change of heart.

A recent study conducted at Adelaide University found that people who regularly drank sugar-free Red Bull had a cardiovascular profile similar to that of people with heart disease. In fact, they found that drinking just one sugar-free Red Bull increased the “stickiness” of the blood and raised the risk of blood clots.

So what causes this? The main ingredients in Red Bull are taurine (an amino acid), glucuronolactone (a normal human metabolite), caffeine, and B vitamins. And the diet version – the one used in this study – is sweetened with sucralose and aspartame.

To beat mid-day fatigue, make sure you stay properly hydrated throughout the day. And enjoy organic green or white tea, lightly sweetened with all-natural stevia. It’s calorie-free too, packed with antioxidants and actually good for your heart.

Kelley Herring is the Founder & CEO of Healing Gourmet – a multimedia company that educates on how foods promote health and protect against disease. As a young adult, Kelley battled a debilitating health condition that went misdiagnosed by multiple doctors for more than a year. Finding no help from “modern medicine”, she turned to her own knowledge of biochemistry and her passion for health research. She soon learned that her symptoms were related to nutrition and within weeks, she charted a course back to health with nothing more than simple lifestyle changes and the power of the plate. The lessons she learned spawned the creation of Healing Gourmet.
Kelley is a firm believer in vigorous exercise, moderate sun exposure and delicious, healthy, home-cooked meals. She is also the creator of Healing Gourmet’s Personalized Nutrition Software and Editor-in-Chief of the Healing Gourmet book series published by McGraw-Hill including Eat to Fight Cancer, Eat to Beat Diabetes, Eat to Lower Cholesterol and Eat to Boost Fertility.
