One-half cup is not very much, but being aware of how much frozen dessert you are eating will help you budget your calories and food choices for the day. This is similar to many premium dairy ice cream products. Non-dairy treats, though, are much lower in fat, with between 1 and 3 grams per serving. Many are available with only 4 or 5 grams of fat, comparable to many light or reduced-fat dairy ice creams. This is still considerably less than many of the super premium dairy ice creams that contain 18 to 23 grams fat.
Nutrient levels vary considerably with brand and flavor, so compare labels carefully.
I have eaten more than my fair share of these treats, and will testify that many of them are incredibly tasty. A few seem to have a slight beany flavor which I have grown accustomed to, but that some of you may find objectionable. The texture seems close to dairy ice cream, but varies with brand. My favorite advice is always to try different flavors and different brands, as you WILL find several you really like. All these ingredients are found in many flavored dairy ice creams, too.
