Final answer:
Heavy cream or whipping cream has the highest fat content but the lowest naturally occurring sugar content among milk types.
Step-by-step explanation:
In terms of milk, whole milk has the highest fat content but also the highest naturally occurring sugar content. However, if you are looking for milk with the highest fat content but the lowest naturally occurring sugar content, your best choice would be heavy cream or whipping cream.
Heavy cream or whipping cream contains significantly more fat than whole milk but has very low amounts of naturally occurring sugar. It is often used in desserts and recipes that require a rich and creamy texture.
It's important to note that heavy cream or whipping cream is much higher in fat and calories compared to whole milk, so it should be consumed in moderation and as part of a balanced diet.
