Study links sugar to heart disease

A study published yesterday by the Journal of American Medical Association (JAMA) concludes that a correlation exists between dietary added sugars and blood lipid levels among U.S. adults.

The culprit: added sugars

The study defines added sugars as caloric sweeteners added to processed foods by manufacturers or added to prepared foods by consumers to make foods more desirable. Sugar added to oatmeal, tea and coffee; sugary drinks, such Coke and Pepsi, and most processed foods meet the description of “dietary added sugars.” Although complex carbohydrates found naturally in fruits and vegetables, such as corn, beets and bananas, ultimately break down and become chemically similar to added sugars, they are not the same as dietary added sugars.

Trans fats and cholesterol have been known to increase the risk of heart disease by collecting along artery walls and eventually hardening into plaque. Although exactly how is not understood, it’s been known that excessive carbohydrate consumption causes a lipid profile that correlates with increased risk for heart disease.

A balanced diet is essential

That doesn’t mean carbohydrates can be eliminated from your diet to reduce your risk of heart disease; they are essential for good health for the energy and nutrients they provide. Added dietary sugars increase total carbohydrate consumption to unhealthy levels without adding any nutritional value. The answer is to eat a healthy diet with balanced portions of protein, carbohydrate and fat. Added dietary sugars upset the balance because they increase carbohydrate levels and they lack nutrients.

Sugar under a different name

Check the sugar listing on the nutritional facts panel and read the list of ingredients for processed and packaged foods. It’s surprising how often added dietary sugar can be found — it’s even in ketchup and mayonnaise. But it’s not usually listed as “sugar” in the ingredient list. This About.com article has a handy list words for added dietary sugar to lookout for in ingredient lists:
