I know this is not a debate forum but I believe there has been some misunderstanding.
I'm not sure what the ultrasound was taken of. A ultrasound of the heart will not see plaque buildup in coronary arteries. An ultrasound of the carotid arteries (neck) may see moderate or advanced atherosclerosis (plaque) but this isn't very common in people in their 30's or 40's. By the time plaque is seen there, cholesterol levels have been high for decades.
1. Cholesterol medications are taken when blood tests show elevated cholesterol levels.
2. A low cholesterol diet can slightly reduce blood cholesterol levels. Medications for cholesterol are taken when diet fails to control high cholesterol levels.
3. A low-cholesterol diet limits animal-based products (meat and cheeses) which are in rich saturated fats and calories.
4. A healthy diet includes plenty nutrient rich foods, low-calorie foods, especially fruits and vegetables.
5. Pasta, soda, sugary cereal, breads, macaroni, etc. are nutrient poor, high calorie foods which cause weight gain (fat) but in themselves do not contain cholesterol.
6. Exercise elevates HDL cholesterol (the good cholesterol). A high total cholesterol is acceptable in the presence of a high HDL.
Hope this helps
