Gastrointestinal Nutrition & Gut Health

Question 1

Which type of fiber is beneficial for promoting healthy digestion by adding bulk to stool?

Accepted Answer

Insoluble fiber

Answer

Insoluble fiber does not dissolve in water and passes through the digestive system largely intact. Its primary benefit is to add bulk to stool, which helps to promote regular bowel movements and prevent constipation. This bulking effect also aids in moving waste through the digestive tract more efficiently.

Question 2

Which vitamin is essential for proper absorption of calcium and maintaining gut health?

Accepted Answer

Vitamin D

Answer

Vitamin D is crucial for overall health, including gut health and the absorption of calcium. It plays a role in maintaining the integrity of the gut barrier and modulating the immune system within the gut. Adequate Vitamin D levels are essential for calcium absorption in the small intestine, which is vital for bone health.

Question 3

Which type of food contains probiotics that help maintain a healthy gut microbiome?

Accepted Answer

Yogurt

Answer

Yogurt is a fermented dairy product that often contains live and active cultures, which are beneficial bacteria known as probiotics. These probiotics help maintain a healthy balance of microorganisms in the gut microbiome. Consuming yogurt can support digestion, enhance nutrient absorption, and boost immune function.

Question 4

What is the primary role of prebiotics in gut health?

Accepted Answer

Provide food for probiotics

Answer

Prebiotics are non-digestible fibers that act as food for the beneficial bacteria (probiotics) already residing in the gut. By fermenting prebiotics, probiotics can grow and thrive, contributing to a healthy and balanced gut microbiome. This symbiotic relationship is crucial for optimal digestive and overall health.

Question 5

Which dietary change can help reduce symptoms of acid reflux and GERD?

Accepted Answer

Eating smaller, frequent meals

Answer

Eating smaller, more frequent meals can significantly reduce symptoms of acid reflux and GERD. Large meals put more pressure on the lower esophageal sphincter, making it more likely to relax and allow stomach acid to reflux into the esophagus. Smaller meals reduce this pressure and prevent the stomach from becoming overly full.
