Question

Which one leaves the human stomach at the earliest?
A. Fat
B. Protein
C. Carbohydrate
D. Beer

Answer 1

Hint: Digestion is the chemical breakdown of the ingested food into absorbable molecules. Absorption refers to the movement of nutrients, water and electrolytes from the lumen of the small intestine into the cell, then into the blood.

Complete answer:
-Carbohydrates, fats, and proteins are the major nutrients the body needs for growth, repair, movement, and maintaining tissue and organ function.
-These macromolecules are broken down and absorbed into the body at different rates and into specific forms as they travel through the organs in the digestive system.
Carbohydrates must be digested to glucose, galactose, and fructose for absorption to proceed.
-Proteins must be broken down into amino acids for absorption. Digestive products of protein can be absorbed as amino acids, dipeptides, and tripeptides. Fats not being soluble in water by their nature are both difficult to digest and absorb. They do not mix with the stomach or intestinal contents.
-Fatty acid is broken down to glycerol to get absorbed.
-Alcohol is not digested like other foods. Once alcohol is swallowed, it travels down the esophagus into the stomach and the small intestine. It avoids the normal digestive process and goes right into the bloodstream.
-Carbohydrates, proteins and fats will remain in the alimentary canal for complete digestion and when broken down completely in the small intestine, it will be absorbed in the intestine but beer will not be digested in the alimentary canal and directly absorbed in the stomach.

So, the answer is D. Beer

Note:
Approximately 20% of alcohol is absorbed through the stomach and most of the remaining 80% is absorbed through the small intestine. Alcohol is metabolized by the liver, where enzymes break down the alcohol.
