Question

A manufacturer markets a 'low-fat' frozen dessert that lists olestra in the ingredients. Analyze the likely effects olestra will have on (a) product calorie content, (b) consumer absorption of fat-soluble vitamins, and (c) possible side effects.

Accepted Answer

Olestra reduces product-available calories because it is non-absorbable, can interfere with absorption of fat-soluble vitamins A, D, E, and K, and may cause gastrointestinal side effects such as oily stools or cramping in some consumers.

Answer

Olestra increases available calories because it is fully metabolized and enhances absorption of fat-soluble vitamins, improving micronutrient status while having no side effects.

Answer

Olestra converts to trans fats in vivo which raises calories and cardiovascular risk directly and is therefore banned in all jurisdictions worldwide.

Answer

Olestra acts like a fiber and selectively increases absorption of fat-soluble vitamins while reducing carbohydrate digestion, making the product superior nutritionally with no trade-offs.
