Scientists at the Children’s Hospital Oakland Research Institute (CHORI) Nutrition & Metabolism Center recently announced that they have developed a low-calorie, high-fiber, fruit-based vitamin and mineral nutrition bar called the CHORI-bar, which improves biomarkers linked to risk of cardiovascular disease, cognitive decline, and associated decline in antioxidant defenses.
Question: I had my cholesterol checked, and I got four numbers back. Which one is most important, and what do the numbers mean with regard to my health?

Daily consumption of two or more drinks per day (where a “drink” contains about 14 grams of pure alcohol, and results are independent of the type of drink consumed) increases breast cancer risk by 50%. These results suggest a much stronger effect of low to moderate alcohol consumption on lifetime breast cancer risk than previous studies [2-4] have done.
New research suggests that the intensity of exercise might be more important than the quantity in helping to prevent death from heart disease and other causes.
In a study presented last week at the European Society of Cardiology Congress 2011, scientists described new research that examined the relationship between exercise duration, exercise intensity, and total risk of death [1]. Lead researcher Peter Schnohr of Copenhagen, Denmark explained that both male and female cyclists had a decreased total risk of death if they cycled vigorously (by their own perception), but that cycling duration didn’t show a similar protective effect.
A recent study evaluating the effects of fast-food-based overeating on liver enzymes and liver triglyceride content has been making the news this week. However, most media sources have been incorrectly interpreting the results. The Swedish study, published in the British Medical Association journal Gut, suggests that eating too much fast food can cause liver damage [1].
