Taking the fat out of ice cream and other frozen treats not only takes some of the fun out of dessert, but it also tends to round things out with additives that don't bring the same nutrition as real dairy. When made with real, full-fat milk, ice cream contains calcium and protein your body needs for good health. Some research even shows that consuming whole dairy is not typically accompanied by a higher risk of weight gain, heart disease, or type 2 diabetes.
Sometimes, selecting a low-fat version doesn't even save you that much fat. Kroger's Low-Fat Vanilla Ice Cream contains just 2.5 fewer grams of fat than its Deluxe Artisan Vanilla Bean Ice Cream.
