What are low fat, reduced fat, and fat-free?

The most time I spend in Walmart is when I stand in the aisle and hesitate to choose among the low fat, reduced fat, and fat-free string cheese. What I always think is that “What do low fat, reduced fat, and fat-free really mean?” “Are they really different from each other?” or "Do I gain less fat if I eat fat-free cheese?" In fact, I always end up choosing the “original” one.

          The only thing I knew was that FAT is the most useless nutrition (this is my own opinion). And for any kinds of foods, the low fat, reduced fat, and fat free are “healthier” than the original one. But I had no idea how they actually work.

          Penny Klatell, in his article “What’s the difference between Low fat, Reduced Fat, Light, Lean”, stated that Fat Labels includes total amount of fat, saturated fat and unsaturated fat.

·       Low fat means 3 grams of fat or less per serving (or per 100 grams of food)

·       Reduced fat means the food product contains 50% (or less) of the fat found in the regular version

·       Less fat means 25% or less fat than the comparison food

·       Fat free means the product has less than 0.5 grams of fat per serving, with no added fat or meal

In other words, the percentage of fat in each fat labels are different. The order of fat from the highest percentage to lowest percentage is original, reduced fat, less fat, low fat, and fat free.

In fact, I avoid eat fat-free foods because I cannot imagine how does fat free version of fat and cream-based foods taste like. And I don’t think eating fat-free ice cream, cheeses, milk, and butter can be called eating “healthy”. I would rather eat apple or carrot with full-fat ranch sauce instead of eat fat-free chocolate ice cream.
