Cholesterol in itself isn't bad at all. In fact it is needed for good health. It's the type that you have particle wise that makes the difference. Also big are the Triglycerides (unhealthy fat in your blood). Added sugar in your diet is toxic to your overall health. Many people with perfectly good cholesterol numbers have heart attacks. Genetics play a big part as well.
The Western diet and especially the American diet is really a recipe for disaster. If you ever get to watch the documentary "FED UP" it will be quite an eye-opener. The stuff that the food industry is putting out and the rise in obesity in this country (and elsewhere) is shocking.
Real food is good food and anything coming in a box............
