how bad

I think the worst of the three food groups you mention are saturated fats because it can harm both ill and healthy persons.Sugar and salt are needed by our body in moderate amounts and it may not harm you if you're not suffering from diabetes and hypertension.Besides,saturated fats is not needed by our body. As with your health conditions,you really need to avoid all these kinds of food.

Yes you have to not eat to much sweet stuff,not to much salt, not too much meat and starch, but the most important things is that you have too avoid is all the (genetically modify organism) in the food that you eat, best to eat more organically.

I'm going to say sugar. It's not good for diabetics and it raises your blood pressure as well as being hard on your digestive system. The other two are bad, but can be handled in small amounts. Saturated fat, as long as it's natural, isn't as bad as they'd have you believe. It's the unnatural saturation that causes problems. Salt isn't as bad as an unbalanced diet. Salt needs to be balanced with potassium. Sugar, on the other hand, is mostly not natural to our diets. We would naturally eat a small amount of fructose as is found in fruit, compared to the horribly high amounts found in almost all processed foods. Add to that, desserts and "treats," sugary drinks and on and on...
