carbohydrate

Put down that PB&J on white bread and listen to this: In a just-released landmark study, researchers at Tel Aviv University’s Sackler School of Medicine and the Heart Institute of Sheba Medical Center found that high carbohydrate foods can be extremely dangerous to the health of your heart. Implicated foods include the “bad” carbs like white bread, sugary cereals, cookies and cakes.

While this isn’t exactly new news, this important study provides a direct reason why these high glycemic foods wreak havoc on the heart and increase risk of heart disease. The researchers showed that after you eat a carb-laden food like a bowl of corn flakes or a Twinkie, your brachial arteries become distended, or swollen, for several hours. While it’s important for the arteries to have a certain amount of elasticity in them, over time, a sudden expansion of the arteries, which follows after noshing on a carb-filled snack, can cause a number of negative health effects, including reduced elasticity, which can cause heart disease or sudden death.

On Thanksgiving, I will be surrounded by 40-50 family members. After we share our feast from appetizers to desserts, several of us will find a spot in front of the television to watch football and doze through commercials. Although I would like to see the Lions hand the Titans another loss (I am a true blue Colts fan!), surrendering to “turkey-daze” is part of the holiday, right? It is commonly believed that the tryptophan in turkey induces sleepiness; however, there is more to our holiday drowsiness than this one chemical.

Tryptophan is one of ten amino acids that the body cannot manufacture on its own and must be supplemented through diet. Tryptophan aids in the production of the B-vitamin niacin which then assists the body’s production of serotonin. Serotonin helps us regulate mood, aggression, anxiety, impulsiveness, body temperature, appetite, and sleep. However serotonin cannot cross the blood brain barrier, meaning we cannot create more serotonin in our bodies.
