Summary Introduction
To review:
The vitamin deficiencies that would occur because of the higher consumption of olestra and the reason for such effect.
Introduction:
Vitamins are micronutrients that are required in very small quantities, but are essential for the body. Without these organic molecules, the body does not function properly. These are to be taken up through a vitamin-rich diet because the body does not synthesize vitamins on its own.

Lactose intolerance is caused by reduced production of the enzyme lactase. A variety of digestive system problems, such as celiac disease and Crohn’s disease) can also lower the production of lactase. If an individual produces low levels of the enzyme lactase, explain why they might be able to tolerate eating dairy products that contain lower levels of lactose (e.g., hard cheeses, feta cheese, and cottage cheese), but will not be able to tolerate foods with high levels of lactose (e.g., milk).
According to current dietary recommendations, trans fat intake should be limited. How is this best accomplished?
Group of answer choices
Select foods containing manufactured rather than naturally occurring trans fats.
Read labels to select foods that say “polyunsaturated fatty acid free.”
Choose foods with <10% of calories from saturated fat per serving and no hydrogenated oils in the ingredients list.
Use fat replacers, such as olestra, which provide the same nutrient content as regular fats without being saturated.
Avoid all processed foods such as bakery items, packaged cookies, and store-bought bread.
Which of the B vitamins are intricately involved in the breakdown and processing of proteins?
Vitamin B1 and Vitamin B2
Vitamin B2 and Vitamin B5
Vitamin B2 and Vitamin B3
Vitamin B5 and Vitamin B6
