What is healthy, or good for you, may very much be determined by a person's overall health and other factors,such as anymedication that's being taken. For example, if one is a diabetic, oatmeal with fruit may not be such a good thing as the oatmeal contains a fair amount of carbohydrates and fruit contains a fair amount of sugar, both of which can contribute to an increase in blood sugar. OTOH, bacon and eggs contains virtually no carbohydrates and sugar, and will have no effect on blood sugar. In fact, fats can slow down the conversion of carbs to sugars. So, if choloesterol and fat is not an issue, bacon and eggs can be a better breakfast choice than oatmeal and fruit.
If one is taking certain medications, such as certain statins, grapefruit may not be desireable.
So, what is healthy depends on many factors as well as how the individual is treating those factors.
