Fat Substitutes and Health

Are fat substitutes safe?

By Peggy Trowbridge Filippone, About.com

It is not easy getting a handle on fats. Science has come a long way in determining the role of fats in a healthy diet. Believe it or not, fat is actually necessary to our diets. Some vitamins are strictly fat-soluble, meaning they cannot be delivered to the body via any other method. Vitamins A, D, E, and K provide energy reserves and are fat-soluble vitamins. Of course, fat is the insulator for the body and protects body organs. Let us not forget that fat is essential to the production of sex hormones; and yes, it really is brain food!

However, not only do we need to follow the old adage of "all things in moderation," but we also need to choose the right fats for the needs of our bodies. How to control cholesterol? Just refer to another old standard:  "Diet, exercise, weight control, and no smoking."  But, you already had a clue about that, right?

Warning!:  Do not put small children on a fat-free diet without consulting your physician. Very young children need fats in their diet.

About Fat Substitutes

There are a number of fat substitutes and additives already in many low-fat foods. The most controversial synthetic fat, Proctor & Gamble's Olestra®, (registered as Olean®) has been approved by the FDA for use in the United States to both public intrigue. Of course we'd all love a no-calorie fat that adds the flavor and texture of the real thing, but many health professionals question its safety. Olestra® is synthesized from sugar and fatty acids. It passes through the body without being digested or absorbed, and thus has no calories. It can withstand high heat, making it perfect for frying foods.

However, since it is not digested nor absorbed, it does not release fat-soluble Vitamins A, D, E and K which have been shown to be cancer-fighting agents. Deficiencies of these particular vitamins can lead to diseases of the blood and liver. Studies have also shown that a significant number of human subjects suffered diarrhea and cramps after ingestion of Olestra products. Yet, the company maintains the product is safe for consumers. Probably the best bet is to stick with the real thing in moderation.
