Evaluate how good ice cream is for a healthy diet.

Ice cream, like many other sweets, is a treat that should be consumed in moderation in the context of a healthy diet. While delicious, it is usually high in sugar, calories, and saturated fat, all of which can have negative effects on your overall health if consumed in excessive amounts. 

In small quantities, ice cream can be a part of a balanced diet. It can provide calcium and other essential nutrients from the milk or cream used to make it. However, it's important to keep in mind that there are often healthier sources of these nutrients, such as low-fat dairy products or leafy green vegetables. 

In summary, while ice cream is not inherently unhealthy, it also isn't considered a health food. Enjoying it in moderation can be perfectly fine, but if you're concerned about maintaining a healthy diet, it's best not to make it a regular part of your diet.
