Skim milk is a type of milk that has had most of its fat removed, resulting in a lower calorie content compared to whole milk. It typically contains about 0.5% to 1% fat, making it a popular choice for those looking to reduce their fat intake while still enjoying the nutritional benefits of milk, such as calcium and protein. This milk is often used in cooking and baking, as well as in beverages like smoothies and coffee. Many people choose skim milk as a healthier alternative to whole milk, especially in diets focused on weight management or heart health.
