What Is in Coca Cola and How Does It Affect the Heart
A standard 12 oz can of Coca Cola contains 39 grams of added sugar and 46 milligrams of sodium, according to the brand's published nutrition facts. The American Heart Association recommends no more than 25 grams of added sugar per day for women and 36 grams for men, meaning one can exceeds the daily limit for women. Excess added sugar intake is associated with weight gain, insulin resistance, and higher triglyceride levels, which are established risk factors for coronary heart disease and stroke. The Coca Cola Company discloses ingredient and nutrition data on its global website and in its annual reports submitted to the U.S. Securities and Exchange Commission via SEC filings.
Coca Cola also contains caramel color, phosphoric acid, and caffeine, which contribute to its flavor and acidity. Caffeine in a 12 oz can is about 34 milligrams, a level generally considered safe for most adults, but sensitive individuals may experience temporary increases in heart rate and blood pressure. Phosphoric acid gives the drink its tangy taste and low pH, which can affect tooth enamel and, in excess, may influence mineral balance in the body. The Coca Cola Company publishes ingredient information for its products in multiple countries and references external nutrition databases as reported by Forbes.
How Sugar Sweetened Beverages Like Coca Cola Relate to Heart Disease
Sugar, Blood Sugar, and Cardiovascular Risk
Large cohort studies and meta-analyses published in peer reviewed journals have linked high consumption of sugar sweetened beverages to increased risk of type 2 diabetes, hypertension, dyslipidemia, and cardiovascular events. The Global Burden of Disease study and related analyses identify sugar sweetened beverages as a major dietary source of added sugars in many countries, including the United States. The Coca Cola Company's portfolio includes carbonated soft drinks, juices, and sports drinks, and the company reports global sales volumes and revenue in its annual financial disclosures on its corporate site.
Obesity, Visceral Fat, and Heart Strain
Calories from sugary drinks are less satiating than calories from solid food, which can lead to excess calorie intake and weight gain over time. Obesity, especially visceral abdominal fat, raises the risk of high blood pressure, high LDL cholesterol, and insulin resistance, all of which strain the heart and blood vessels. The American Heart Association and the World Heart Federation emphasize reducing added sugars as part of a heart healthy dietary pattern to lower the risk of heart attack and stroke per the American Heart Association.
Sodium, Blood Pressure, and Long Term Heart Outcomes
Sodium in Carbonated Soft Drinks
While sodium levels in a single can of Coca Cola are moderate compared with processed foods, frequent consumption of multiple servings can add to total daily sodium intake. High sodium intake is a well documented contributor to elevated blood pressure, which is a leading risk factor for ischemic heart disease and hemorrhagic stroke. The World Health Organization recommends limiting sodium intake to less than 2,000 milligrams per day for adults, and people with hypertension
